Dear Family, your Operation Maths guide to Counting and Numeration

Dear Family, given below is a brief guide to understanding the topic of counting and numeration, as well as some practical suggestions as to how you might support your children’s understanding at home. Also below, are a series of links to digital resources that will help both the children, and you, learn more about place value. The digital resources are organised according to approximate class level:

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class.

Understanding Counting and Numeration

Counting and numeration is about the counting words we use to tell the amount in a group, and the numbers we write for those counting words. And counting is not just about chanting a series of numbers …’one, two, three, four, five…’. It is about using these numbers with meaning, for example, understanding that the word ‘five’ can be written as 5, that it comes after four and comes before six, and that it can be used to describe the amount in a group of five items (and not just the label for the last item in the count). So, even though your child may know how to count to 10 or 20 or more, by the time they come to primary school, this does not necessarily mean that they understand the meaning of each number, or its place in the counting sequence. This is often described as the difference between rote counting (chanting a sequence of numbers) and rational counting (counting with understanding); for more on this, please check out the one minute video below.

Counting and numeration is a strand unit in Primary Maths for children in junior infants to second class only. Children in the senior classes will still do a lot of counting and numeration activities, but mainly as part of the strand unit place value. In the younger classes, the type of learning activities are very similar at every class level; the main difference is that each class level will have different number limits. In school, we expect that most children should be able to read, write and use numbers:

  • 0-5 by the end of junior infants, and be able to count to 10
  • 0-10 by the end of senior infants, and be able to count to 20
  • Up to 99 by the end of first class
  • Up to 199 by the end of second class

That is not to say that you should limit your child to only counting up to the number limit for his/her class level. In reality, children will encounter much larger numbers in the real world, than they will encounter in their maths books, so feel free to include larger numbers when you meet them. But, bear in mind that, even if a child can read or say a large number, it doesn’t necessarily mean that they understand it.

Practical Suggestions for Supporting Children

  • Count, count and count some more! Count out the plates at the table, count out sweets or treats, count steps as you go up and down stairs, count down the days left to a birthday; use every opportunity for your child to hear you count, and when ready involve them in the counting.
  • Say rhymes and sing songs that involve numbers or counting, for example, One, Two Buckle my Shoe, Five Fat Sausages, Ten Green Bottles, etc.
  • Watch Numberblocks and Numberjacks. Many of the episodes from these two award-wining series from the BBC are available on-line and may also be available on your TV if you have BBC.
  • Develop counting skills though play:
    • Play tea-time with the toys, where each toy gets one cup, one plate, one bun etc. No toy should have more than one, and no toy should have none. These activities help to reinforce the one-to-one correspondence required in counting correctly.
    • Play counting games at home (for example throw items into a basket/box and count them as you throw) and ordering games, for example where you layout playing cards in order. Or guessing games, where you estimate (guess carefully) the number of items in a container, bag etc., and then count to check.
    • Play board games where the child has to throw a dice, recognise the number of dots shown, and then move on a counter that number of places.
    • Play games where each number in a sequence (e.g. 1 to 10; 45 to 55; 103 to 113) is written on piece of paper/card and placed face-down. The child must turn over every piece in turn and read aloud the number. Then, he/she should put the numbers in a line in order. Finally, you could play hide and seek: remove a number from the line and your child has to tell you the missing number.
    • Play counting games on car journeys, e.g. each child in the car picks a colour and counts every car of that colour that they see or meet on the road. The winner is the person who hits the highest number before the driver’s patience wears out!
  • When your child starts to write numbers, you will need to monitor their number formation very carefully; it it very important that they don’t get into the habit of writing a number incorrectly.
  • Draw your child’s attention to numbers around your home and in the wider environment, e.g. numbers on signposts, car registrations, phone numbers, the number of pieces in a jigsaw, page numbers on catalogues, the numbers on houses or hotel rooms. When you spot a number, ask them to read it out.
  • With older children, when you are talking about numbers be careful to use the correct language e.g. for 125 say ‘one hundred and twenty five’ not ‘one-two-five’
  • It’s an unfortunate convention, but the way we talk about numbers every day, can often be mathematically incorrect and/or confusing. For example, when calling out a mobile number, that starts with 08….. we will likely say ‘oh eight‘…… Yet 0 is a digit called zero, whereas O (said as ‘oh’) is a letter of the alphabet and not a number at all! So, when verbalising numbers with zero, try to get into the habit of saying ‘zero’ instead of ‘oh’.
  • Numbers that end in ‘-teen’ or ‘-ty’ can be difficult for some children. In particular, some children can have difficulty hearing the difference between numbers ending in ‘-teen’ and ‘-ty’ when they are spoken out loud, e.g. ‘fifty’ (50) sounds very like ‘fifteen’ (15) when spoken, yet their values are very different. Try to say these type of numbers clearly, and encourage your child to say them clearly also, so that they appreciate the difference between these similar-sounding numbers.

Dear Family, your Operation Maths guide to Early Mathematical Activities (EMA)

Dear Family, given below is a brief guide to understanding the topic of Early Mathematical Activities (EMA) as well as some practical suggestions as to how you might support your children’s understanding at home. Also below, are a series of links to digital resources that will help both the children, and you, learn more about Early Mathematical Activities.

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book

Understanding Early Mathematical Activities

Early Mathematical Activities is a strand in Primary Maths for children in junior infants only, although the activities can also suit children at the beginning of senior infants, as revision, as well as being suitable for many children in their final preschool year. The focus is on doing activities, that develop the child’s mathematical thinking, but that do not involve number or counting. The children will be:

  • identifying things that are the same, and things that are different
  • matching pairs of items that are identical and/or items that belong together
  • classifying (sorting) items into into groups that are identical and/or belong together
  • comparing items and sets of objects to determine which is larger or has more, and ordering objects according to to a certain criteria e.g. their length, size, weight etc.

All of these type of activities help prepare the children for later, similar activities, involving numbers and counting.

As mentioned, an essential skill is for the children to recognise objects and images that are the same and that are different. The objects may be completely identical in all features, or have the same colour but a different shape or size. The children will learn to match identical items (e.g. socks) and to match items that are different but belong together (e.g. fork and spoon). Later, the children will learn to sort items into different groups, depending on the purpose.

Practical Suggestions for Supporting Children

Most of the Early Mathematical Activities can be incorporated into the various tidying and sorting/organising activities that occur regularly around the home:

  • Putting away or sorting clothes. Ask your child:
    • ‘What items are identical (or exactly the same) and belong together in matching pairs?’ For example socks.
    • ‘What items are identical or exactly the same and but don’t belong together in matching pairs?’ For example any t-shirts, or jeans, or pieces of underwear that are identical.
    • ‘What items are not exactly the same, but do belong together?’ For example, a pyjama top and bottom set, a shorts and t-shirt set etc.
    • ‘What items are the same colour?’
    •  ‘What items are different from everything else?’
  • Sorting, for example, the drawer of kitchen utensils and/or cutlery:
    • Organise the contents into groups of items that are identical or exactly the same.
    • What items don’t belong in any group e.g. a large soup ladle or wooden spoon? These items are different.
    • Can you find any items that are similar, and do the same thing but do not look exactly the same? e.g. different types of spoons
    • Can you find items that are not the same but usually go/belong together? E.g. fork and knife
  • Tidying up the toy box or play room. Ask your child to suggest ways to sort the items into groups e.g.
    • Sort according to type: all the similar items together, e.g. books, cars, dolls etc
    • Sort according to colour: all the red items together, all the yellow items together
    • Sort according to size: all of the large items together, all of the small items together
    • Sort according to owner: all of each child’s toys together
    • Organise the Lego pieces; you might sort them according to colour, shape, size or purpose e.g. all the wheels together, all the doors and windows together, all the mini-figures together etc.
  • Identifying colours:
    • Pick up something and ask your child to find another one that is the same colour or a different colour.
    • Organise items into groups of the same colour. Ask your child to name the colour.
    • Ask your child to show you an example of items that are the same colour, but not exactly the same (i.e. different shades of the same colour), and to use the words dark and light to describe these colours e.g. light blue and dark (or navy) blue.
    • Play ‘I spy with my little eye something the colour of …..red’. Repeat with other colours.
  • Go on a walk outside. Ask your child if they can you find any items from nature that are identical or exactly the same? Can he/she find any items that are different?

Dear Family, your Operation Maths guide to Place Value

Dear Family, given below is a brief guide to understanding the topic of place value as well as some practical suggestions as to how you might support your children’s understanding at home. Also below, are a series of links to digital resources that will help both the children, and you, learn more about place value. The digital resources are organised according to approximate class level:

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class, and in the Operation Maths Dear Family letters for third to sixth class.

Understanding Place Value

Place value is about exploring the base-ten number system we use: how our numbers are made up of digits, each of which represent different values, depending on their position or place in the number. In the senior classes the children will explore place value in numbers with a decimal point, as well as numbers without a decimal point (whole numbers).

No matter how large a number is, you really only need to know how to read a three-digit number, to be able to read any size number. This is because the digits are always organised in groups of three, as you can see in the image below. However, we do also need to know the significance of the commas. For example, three (3) million, six hundred and twenty-three (623) thousand, nine hundred and fifteen (915) = 3,623,915: the comma closest to the units is read as thousand, the next comma is read as million, etc.

At its most basic level, central to understanding our place value system, is to recognise that 10 single items or units or ones, can be grouped together to make a ten; that 10 tens can be grouped together to make a hundred; that 10 hundreds can be grouped together to make a thousand etc. In school, the children have lots of different materials that they can group together, or exchange, such as cubes, bundles of sticks, counters on ten frames and place value discs. At home, the children could bundle cotton buds or cocktail sticks or trading cards into groups of tens and fasten them with an elastic, or group identical pieces of lego into sticks of ten, or count out beads or buttons or pieces of pasta into small containers or bags as groups of tens.

Example of materials that might be used in school: place value discs, bundling sticks and base ten blocks

In school, the type of place value learning experiences that the children have, are very similar at every class level; the main difference is that each class level will have different number limits. In school, we expect that by the end of first class, most children will understand place value in numbers up to 99, in second class up to 199, in third class up to 999, in fourth class up to 9,999, in fifth class up to 99,999 and in sixth class there is no limit … millions, billions, trillions even!

That is not to say that you should limit your child to the number limit for his/her class level. In reality, children will encounter much larger numbers in the real world, than they will encounter in their maths book, so feel free to throw bigger numbers at them. But, bear in mind that, even if a child can read or say a complicated number, it doesn’t necessarily mean that they understand its place value.

Practical Suggestions for Supporting Children

  • Ask your child to read out loud any numbers they meet around your home and in the wider environment, e.g. numbers on signposts, car registrations, the number of pieces in a jigsaw, page numbers on catalogues, the numbers on houses or hotel rooms, larger numbers on fact books e.g. Guinness Book of World Records, recorded times for races, etc.
  • Correct language: When you are talking about numbers be careful to use the correct language e.g. for 91,856 say ‘ninety one thousand, eight hundred and fifty six’ not ‘nine-one-eight-five-six’ and for 23.95 say ‘twenty three point nine five’.
  • Zero does not equal ‘oh’! It’s an unfortunate convention, but the way we talk about numbers every day can often be mathematically incorrect and/or misleading. For example, when calling out a mobile number, that starts with 08….. we will likely say ‘oh eight‘…… Yet 0 is a digit called zero, whereas O or ‘oh’ is a letter of the alphabet and not a number at all! So, when verbalising numbers with zero, try to get into the habit of saying ‘zero’ instead of ‘oh’.
  • Numbers that end in ‘-teen’ or ‘-ty’ can be difficult for some children. In particular, some children can have difficulty hearing the difference between numbers ending in ‘-teen’ and ‘-ty’ when they are spoken out loud, e.g. ‘fifty’ (50) sounds very like ‘fifteen’ (15) when spoken, yet their values are very different. Try to say these type of numbers clearly, and encourage your child to say them clearly also, so that they appreciate the difference between these similar-sounding numbers.
  • Rounding large or awkward numbers is something we do to make them easier to say or report. For example, if there was 91,856 people at a concert or a match, the media might report that there was just over ninety thousand or there was almost ninety two thousand people in attendance. When you encounter numbers in the media, encourage your child to round them; ask him/her what the number would be roughly/approximately. If you come across a number that has already been rounded, together you could guess/speculate as to what the exact number might have been.
  • Make place value fun!
    • Play counting games on car journeys, e.g. each child in the car picks a colour and counts every car of that colour that they see or meet on the road. The winner is the person who hits the highest number before the driver’s patience wears out!
    • Race to the page! Challenge your child to try to find certain page numbers, in books with plenty of pages, as quickly as they can. Use a dictionary or other reference book, or even an Argos catalogue and call out a page number, for example ‘three hundred and ninety’ and see how quickly that page can be found. If you have more than one copy of a suitable big book or catalogue, two players can race against each other.
    • Play some simple place value games using dice or playing cards
    • Play any of the online interactive games below

It is also the most child-friendly program available, designed around incorporating engaging and playful activities that are based on a concrete, pictorial, abstract (or CPA) approach, which enable active participation and learning, while developing a better understanding of maths concepts and facilitating a seamless transition to second level.

It is a completely integrated print and digital package, with a suite of custom made eManipulatives (interactive tools), ready-to-go digital activities, videos, weblinks, scratch (coding) lessons and more!

The design of Operation Maths has been heavily influenced by some of the key maths pedagogies that are widely recognised as the most effective for teaching and learning, and/or which epitomise best practice in teaching maths, in those countries with a strong tradition of excelling in maths education. These key pedagogies include:

In schools where Operation Maths has been introduced, there is evidence that it has had a positive impact on the standardised test results at the end of the first year of implementation.

Since its launch in 2016, Operation Maths continues to evolve in response to the needs of its users. The Operation Maths blog, launched in 2017, continues to provide teachers, and most recently families and children, with information, suggestions and support. Its Digging Deeper into….. blog series (2017 to present), aimed at teachers, looks in-depth at the various primary maths topics, and provides suggestions of further helpful resources etc. Most recently, a new blog series entitled Dear Family (2020) was launched to provide families with a wealth of practical suggestions as to how they might help support their children’s learning in maths, as well as lists of up-to-date, recommended resources, available online.

Dear Family, your Operation Maths guide to Time

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of time. Also below, are a series of links to digital resources that will help both the children, and you, learn more about time. The digital resources are organised according to approximate class level.

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class, and in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • Difficult Topic? Although time plays a very important role in everybody’s life, it can be quite a difficult concept to grasp:
    • Unlike our number system, time is not built around a base-ten system. All of the other maths topics in measures (i.e. money, weight, capacity and length) are all built around units of ten, one hundred, one thousand and so on e.g. 100 c in €1; 1,000m in 1 km etc. But time is totally different: 60 seconds in a minute; 60 minutes in an hour; 24 hours in day; 7 days in a week; 4 and a bit weeks in each month; 12 months in a year etc.
    • While we can’t see or touch time, we have ways to record and show it, but again, there are many different ways to do this: sand timers, sun dials, analogue clocks and watches, digital watches and displays (which can be either 12 or 24 hour), calendars etc.
    • Time is not the same all around the world; each country belongs to a time zone and the time is different in each time zone.
    • Judging how much time has passed can be quite difficult, as it depend on what we are doing; we all have experienced how time can drag, or it can fly when having fun.
  • Talk about time all of the time! When you wake up your child in the morning, (or he/she wakes you!) announce the time and day; how many school days left before the weekend; how long before you need to leave the house; the start time for the sport’s practice or music lesson; dinner time etc. Give your child a set amount of time to complete a task or chore. Try to become a type of talking clock yourself, constantly announcing the time of day and the time left/needed to do something. This will help develop your child’s own internal sense of time.
  • What are we doing today? Involve your child in planning trips, visits and outings: what time do we need to leave to arrive there on time; what time do we need to get up at? How long is it going to take you to get ready? Highlight the importance of punctuality and being on time as a valuable life skill: we need to leave the house at 20 to 9 if we are going to get to the school for 9, etc.
  • Lots of clocks! Try to have plenty of time devices around your home, and of different types, for your child to become familiar with the many different ways to measure time. It is never too soon to have a clock in your child’s own room and/or for them to wear their own watch; however, first clocks and watches should be of the analogue type (i.e. with hands and a face) rather than digital. Even if your child is not able to read the time on the analogue clock face yet, noticing and becoming aware of the movement of the hands and their direction (clockwise) helps develop your child’s sense of the passage of time, a valuable learning experience that will be built upon when ready.
  • Buying a clock: While children need to be flexible, and to be able to tell time using a variety of different time devices, if you decide to buy a first clock or watch for your child, there are some clock features you should consider before you buy (click here to see some suitable examples):
    • All the numbers 1-12 (not roman numerals) shown clearly.
    • Minute intervals (i.e. little lines) shown clearly around the edge of the face.
    • A minute hand that is long enough to show that it is pointing beyond the numbers (which mark the hours) out to the minutes around the edge (the purpose of the long minute hand is to point out to the minutes).
  • Hour is key: When your child asks “what time is it?” ask them to try to work out what the time is roughly for themselves. When looking at an analogue clock, they should always look first at the short hour hand: which number is it pointing to (or closest to)? Then, that is the (nearest) hour. The minute hand only helps us refine that approximate time. When looking at an digital display, they should always look at the first digit; that is the hour that it was last. This is another example of why analogue is better than digital: it is possible to gauge the actual time more accurately using only the hour hand on an analogue clock, than using only the hour on a digital display.
  • Mark the date: Have calendars and/or weekly charts/diaries visible around your home. Use the calendar to mark events that would be important to your child, like birthdays, holidays, Christmas, school concert etc. Involve your child: if there is space available to do so, he/she can mark these important dates using words and/or pictures. Also try to have calendars that start with Monday, since Monday is officially the first day of the week (read on here for more interesting info on this). On weekly charts, mark repeat events like sports practices, lessons etc.
  • Dot, dot NOT dot! When writing or texting a time in digital format (e.g. See you at 6:30) always use a colon (two dots) rather than a single dot (i.e. don’t write 6.30). Firstly, a colon is what is used most often on actual digital displays. Secondly, a dot is identical to a decimal point (e.g. 2.5 meaning 2 and a half or the decimal point used when writing money e.g. €1.20) which, mathematically, is used with numbers on the base-ten system. And time, as we said earlier, does not work on a base-ten system. So using a single dot for writing time, may only confuse children.
  • 24 hour & 12 hour: For the older children, draw their attention to 24 hour time and encourage them to translate 24 hour to 12 hour with a.m. or p.m. and vice versa. Most phones, devices and smart watches have the option to display either version, so perhaps set these to 24 hour time to provide your child with more opportunities to become familiar with it.
  • When is it on? When does it leave? Highlight also any timetables and schedules that the household might use, or refer to, for example TV listings on an Electronic Programme Guide (EPG), cinema timetables, transport timetables (e.g. bus and train), flight arrival and departure times. In the case of an upcoming flight for a family vacation, encourage the children to identify the arrival and departure times and to use this information to calculate flight time. If there appears to be a difference between the outgoing and incoming flight times, can the child explain this, i.e. does he/she notice that flight arrival and departure times are always given as local time and that the destination may be in a different time zone?

Maths by Month – June (updated 2020)

Category : Uncategorized

The final month of the school year is almost upon us, and as usual, this heralds the last installment in this year’s series of posts designed to explore the Operation Maths topics on a month-by-month basis.

As teachers and families, around the country, continue to support children via distance learning, we have continued to roll out our latest series of posts entitled Dear Family. Each of these posts focuses on a specific maths topic, and provide practical suggestions as to how families can support their child’s learning, along with providing tried and tested links to useful digital resources. We hope that, in some small way, they may prove to be beneficial, both now, and in the future.

The posts in the Dear Family series published to date, focused on the topics of weight, capacity, 2-D shapes3-D objects, number sentences and equations, money and chance. Some of these topics also feature in the plans for this coming month (see below). The next Dear Family posts, currently in development, will focus on the topics of time, patterns and lines and angles.

HINT: To ensure you don’t miss out on any future Maths by Month or Dear Family blog-posts, please subscribe to the Operation Maths blog via email, on the top right hand of this page.
Another way to keep up to date an all new maths-related developments is to like/follow the Edco Primary Maths page on Facebook and/or Twitter 

Please feel free to share any of the Operation Maths blog posts with colleagues and members of your school community, including parents and families, whether they are Operation Maths users or not.

Book lists not finalised yet? Please consider Operation MathsNumber Facts, Bua na Cainte, Exploring Spelling, Let’s Talk Literacy, Explore with Me and My Learner ID. Click on the links for more information and to view sample pages from each program and/or contact your local Edco reps for samples.

Operation Maths for Junior Infants to Sixth Class:

  • Junior Infants: will be reinforcing their understanding of the numbers 0-5 via the topic of money.
  • Senior Infants: Further Counting and Numeration, Comparing and Ordering and Combining and Partitioning of numbers to 10; patterns (different arrays of the same number, colour patterns, number patterns, odd and even numbers); time (one-hour intervals).
  • First Class: Weight; Patterns; 3-D objects (in particular, connecting their understanding of 3-D objects to their understanding of 2-D shapes)
  • Second Class:  More Place Value to 199; Area; Lines and Angles (revisiting half turns and quarter turns)
  • Third to sixth classes: Operation Maths 3-6 is specifically structured so that the programme can be completed by the end of May, thus covering all of the topics in advance of the standardised testing.
    Depending on your own specific school circumstances, you may find yourself looking for inspiration to fill the maths lessons from now until the end of month. Whether you’re an Operation Maths user or not, there are a whole suite of suitable ideas on this blog post.

Operation Maths users can also access custom-made digital resources to support these topics. To access these resources, log into your account at www.edcolearning.ie, select the At School Book/Pupil’s Book for your class level. Then you can either:

Dear Family, your Operation Maths guide to Chance

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of Chance (for 3rd-6th classes only). Also below, are a series of links to digital resources that will help both the children, and you, learn more about Chance.

Junior Infants to Second Class
You can also find class specific tips in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • Chance is one of the most interesting, and fun, areas of primary maths, since it is mostly about probability, i.e. identifying the possible outcome(s) of random events. With your children, talk about ‘chance’ whenever you have the chance (excuse the pun!):
    • What is the chance that you’ll go to school today?
    • What is the chance that you’ll get homework today?
    • What is the chance that you’ll get to watch TV or get to play computer games?
    • What is the chance that it will be warm tomorrow, that it will rain, that it will snow?
    • What factors affect the likelihood of these events occurring? For example, the day that it is, the time of year, whether the child has done their chores etc.
  • In school, we use language such as impossible, (highly) unlikely, may or may not, possible, (highly) likely, certain, etc., to describe the likelihood of events occurring. Encourage your children to use these words as accurately as possible, especially the words impossible and certain. For example:
    • On a sunny day, what is the chance of rain? Unlikely or highly unlikely you could say, but it wouldn’t be correct to say impossible, because anything is possible!
    • On a day when you have organised to do something e.g. go shopping, what is the chance of it happening? Likely or highly likely, because it is already organised, but it is not certain, because again anything could happen to disrupt the well-made plans, like the car mightn’t start.
    • If I toss a 6-sided dice once, what is the chance of getting a 7? Now that’s impossible! What is the chance of getting a number from 1 to 6? That is certain!
  • Children in 5th and 6th classes are also encouraged to use more mathematical ways, including using fractions, decimals and percentages, to express probability e.g. 100% certain, a 1 in 4 chance, 50/50, etc. This type of language could also be included in your discussions at home.
  • So, no matter how accurate the mathematical prediction, the actual outcome(s) is not certain (except in the unlikely case where there is only one possible outcome); that is the element of chance! For example, when I toss a six-sided dice, each number has a equal chance of coming up. Therefore, if I do this repeatedly for a number of times, I could expect to see equal occurrences of each number. Yet that might not happen in reality! But, it is most often the case, that if you repeat this type of investigation enough times, the actual results WILL end up being very close to the predicted outcomes. In other words, the more you do something, the more likely it will happen as predicted. Some of the activities in the Operation Maths books are specifically designed to explore this. So try them and see!
  • Many games are designed around random outcomes so play board games, card games, dice games, any type of game where you can’t know from the outset who will definitely be the winner! Ask the children before you play, and as you play, who do they think will win and why; perhaps somebody in the family is a dab hand at rolling sixes, is a card shark or after a number of turns is already way ahead of everybody else. At the end of the game did that person win? Perhaps, on this occasion, a person was dealt “bad” cards, or the dice didn’t fall as hoped for, or another player caught up and overtook the early leader. Or maybe not! Experiences like this, help the children appreciate how lots of different factors can influence and affect an outcome, and that they can predict winners or outcomes based on the best information that they have at the time, but that the predicted outcome may or may not materialise.
  • Study the weather! Look at the sky and discuss the chances of rain, sun, snow, lightning etc. Look up Met Éireann’s website to find out the weather forecast for your area and then, afterwards, discuss whether the predicted weather arrived. Again, while meteorology, the study of weather, is a science in itself, it is still involves using the best scientific information available at the time to predict the weather, which, in the end, may or may not happen.
  • Sport provides us with an abundance of opportunities to discuss chance:
    • What are the chances of a particular team or individual winning a game, match, fight, competition or race?
    • Before the event could you predict an outcome?
    • What information about the competitors or teams might be useful to influence this predication?
  • Draw the children’s attention to any other situation where chance plays a role e.g. the chances of winning a raffle or the lottery.

Dear Family, your Operation Maths guide to Money

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of money. Also below, are a series of links to digital resources that will help both the children, and you, learn more about money. The digital resources are organised according to approximate class level.

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class, and in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • Difficult Topic? Although money plays a very common, and perhaps very important, part in every child’s life, money is not automatically easy or obvious to learn about:
    • It comes in different colours, shapes and sizes, and in metal and paper forms (i.e. coins and notes), each of which has its own value.
    • The sizes of the coins and notes are NOT proportional to their value i.e. a 20c coin is not twice as big as a 10c coin; a €100 note is not ten times the size of the €10 note.
    • Money can be expressed using the symbols € or c, but NOT using both at the same time. Sometimes there’s a decimal point; sometimes there’s not. And, when using the € sign, it comes first (even though €6 is said as “six euro” as opposed to “euro six”), whereas the c sign comes after the numeral.
    • So even though understanding and using money is a vital life skill, it can’t be taken for granted that children will easily “get” this understanding.
  • Cash starved: More and more, transactions are becoming cashless, as people use credit/debit cards, money apps, contactless and online payments more than ever before. In the recent past, coins and notes, were very much a regular part of a child’s experiences; watching others counting out coins and notes to pay for goods, perhaps handing over a larger amount than required and watching change being handed back. Because of cashless transactions, today’s children are missing out on essential opportunities to handle cash, and/or see it being handled in real-life situations. The increased use of plastic and contactless payments also limits the opportunities for people to use their maths skills to total mentally, calculate change etc.
  • Cash is King: Since today’s children have less exposure to cash transactions, where possible, allow your child to handle real coins and notes.
    • Collect coins in a jar and invite your child to count the money every so often to find out the total. Are there different ways to count mixed coins? What strategies might be better (more efficient)?
    • If your child is not able to count up the total of amounts yet, then ask them to sort the coins into groups e.g. brown coins, gold coins, coins with two colours, coins with 1 on them, with 2 on them, with 5 on them etc (see also the Coins Game below). In particular, draw their attention to the fact that all the euro coins and notes only start with the digits 1, 2 or 5 and may or may not be followed by one or two zeros.
    • Play shop at home. Use empty food containers etc., as goods to be bought/sold. Use play money or real coins for cash.
    • If shopping with cash, involve your child: get them to handle the money, to identify the coins and/or most suitable amount to hand to the cashier and to predict (roughly or accurately, depending on the ability of the child) the change due back.
    • If your child gets pocket money encourage them to talk about how much they have, how much they spend, how much they have left.
  • Can you afford it? Should you buy it? While cashless transactions might be more regular than cash ones, one thing that has remained constant is that we all still appreciate the value of money, and getting value for our money.
    • Encourage your child to budget and save for upcoming events (Christmas, holidays etc.) and/or to purchase more expensive items ( eg bike, games console, phone etc). Discuss the amount of money required, how much they currently have, how much they could expect to earn and/or save each week, how long it will take for them to have the necessary amount. Encourage them to write down this information as a type of written budget or financial plan (see also the Budget Game below, for 3rd class up).
    • When purchasing items encourage your child to consider its value, its cost, and whether a similar item be purchased elsewhere for less. Shop around, as they say, to research your options, whether in the actual or virtual (online) shops.
    • When grocery shopping, keep an eye out for the advertised special offers and deals; are they good options? What about multi-packs; are they good value? If there are different multi-pack offers for the same product, which offer is the best value? But don’t forget that just because there is good value on offer, if we end up buying more of the product than we need, will it end up going to waste?
    • Go through the till receipt together after shopping; what did you buy? What items cost the most? What items cost the least? What products cost about the same amount? Was there any product that you hadn’t realised cost so much or so little?
    • When out shopping for clothes, give your child a limit to the amount that can be spent. It is amazing how value-driven this can make your child become, and more selective of what they will purchase!
    • If you are comfortable allowing your child to use the internet, he/she could help research a holiday or break for the family. Examine together which destination has the best deal/offers, etc.
  • Money makes the world go round! Children may not realise that, outside of the Euro Zone, most countries have their own currency. And they may also not realise that, when changing currency, you cannot do a straight swap i.e. €1 doesn’t equal £1 or $1; the new value must be calculated using an exchange rate, which also varies. If going on holiday to a non-Euro Zone country, involve your child in researching the exchange rate, and calculating how much of the foreign currency they will get when they exchange their euro.

Dear Family, your Operation Maths guide to Number Sentences and Equations

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of Number Sentences & Equations (for 3rd-6th classes only). Also below, are a series of links to digital resources that will help both the children, and you, learn more about Number Sentences & Equations.

Junior Infants to Second Class
You can also find class specific tips in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • Number sentences are a part of Algebra. Number sentences are mathematical sentences made up of numbers, symbols and/or signs eg 11 – 4 = 7, 3 × 6 = 18. They can use simple numbers or be more complicated with bigger numbers, letters, fractions etc. Number sentences can be equations, where both sides are equal/balanced (4 + 2 = 5 + 1), or be unequal (4 + 5 > 6 + 2) where one side is greater than or less than the other side. Sometimes, the children are given complete number sentences and are asked to work out if they are true or false. More often, in primary maths, number sentences will have a frame or box to represent the missing value/number which must be worked out or solved e.g. 5 + ☐ = 9. The missing value may also be represented by a symbol or a letter (called a variable) eg 14 – 🌳 = 8, y + 5 = 20
  • An essential aspect of exploring number sentences is reading and interpreting correctly the signs and symbols. However, for children, the signs and symbols can be very confusing, because they can be so similar and yet all mean something completely different. Take for example + and × ; they are actually the same shape, but turned to look different. And they have very different meanings; the first means add and the second means multiply. Consider some of the other common maths signs: = ÷ – < >. These are all very similar to each other in design and shape, but very different in meaning. No wonder children can get confused! That is why, even though the children will come across number sentences in infants to second class, they will not actually explore this topic in depth, until they are in third class and higher.
  • Of all the signs used in maths, the equals sign (=) is one that is often misinterpreted. The sign itself is made of two identical lines, to indicate “same-ness”. So this sign is saying that the value of whatever comes before it, is identical to, or the same as, the value that comes after it e.g. 7 = 3 + 4. And sometimes there is more than one value on either side of the equals sign, so that each side has to be calculated to see if it is true e.g. 10 – 4 = 3 + 2 + 1 (Tip: the children could write the value for each side above/below that side so that it’s very obvious whether it’s true or not). The horizontal identical lines in the equals sign, also remind us of a balanced scales (see image below), where the total value/weight on both sides, is equal. When reading this sign with your child, always say “equals” or “is the same as”.
  • Number sentences are simply a mathematical way to represent a scenario or story. If I buy three big bars of chocolate, costing €1.50 each, I can show that information with these number sentences: €1.50 + €1.50 + €1.50 or 3 x €1.50. So, often there can be more than one way to represent the information. The child may be asked to represent a story or word problem with a number sentence. Or they may be asked to create a suitable story or word problem to match a given number sentence. You can practice this at home by asking the children to suggest how they’d represent various number scenarios in number sentences, e.g. how to work out the cost of a number of items, the change that would be due after spending a certain amount, the number of sweets that everyone can get when a large bag is shared out, etc. Even if the child does not calculate an answer, it will benefit them to consider how the scenario might be shown using numbers and signs.
  • Whenever your child is working with word problems at home, encourage them to show it as a number sentence first, before they start to solve it. You can also ask them to show you how they sometimes use model drawings or number bond drawings (see image above) at school to help picture the problem. Drawings and diagrams are particularly useful as they encourage the child to see the “big picture” of the maths story, which can be a great help if they are finding the numbers and symbols difficult to interpret.
  • Sometimes your child might be given number sentences and asked to identify if they are true or false. To do this, it is not always necessary to work out both sides of the number sentence exactly. There is (usually) only one true or correct option, meaning that every other answer is incorrect or false. Encourage the children to use their estimation and number sense skills to quickly recognise when a statement is obviously false, e.g. in (c) below, two hundred and something and one hundred and something is definitely not bigger than 500 so I don’t need to work it out exactly to know that it is false. And while you might think this is a type of ‘cheat’ strategy, in reality, it is about using a more efficient approach, while also emphasising the value of estimation.

  • In Operation Maths, the children may be asked to identify the maximum and minimum amounts that could be used in a number sentence. Draw your child’s attention to incidences where maximum and minimum are used in everyday life:
    • you have to be a minimum of 1.1m to go on a certain theme park ride
    • the maximum number of passengers on the bus is 52
    • the maximum speed on a motorway is 120 km/h
    • a child must be a minimum of 15 kg to move from an infant seat to a booster seat in the car.
  • Now that you appreciate how confusing maths signs can be, don’t take it for granted that your child understands the the meaning of all the maths signs that they come across in their books. If your child is working with number sentences, ask them to read the sentence out loud for you and/or to tell you how their teacher verbalises certain signs. In school, we will often use a variety of language to describe a sign and sometimes that depends on the story that goes with the number sentence. For example, with the number sentence 7 x 9 above, that could be verbalised as seven multiplied by nine, seven groups of nine, seven nines etc. 20 ÷ 2 could be verbalised as twenty divided into two equal groups/parts, twenty divided by two, how many groups of two in twenty, etc.
