Maths by Month – June (updated 2020)

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

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:

  • Navigate to the relevant page in the book and click on the hyperlink to open up the specific activity for that page in a new tab.
  • Click on the Edco Resources icon (on book cover image on left-hand side) to open the list of all the digital resources associated with that book.

Other suggestions for June:

  • Maths outside: typically this is the time of the year when teachers are bringing their classes outdoors for learning. Since the children are at home, longing to get into the outdoors, why not encourage them to safely do some of these activities, with their families, while on their outdoor walks.
    • Outdoor Classroom Day 2020 was officially celebrated on May 21. If you missed this day, you can still access their resources with suggestions for all subject areas, including maths, https://outdoorclassroomday.com/.
    • Maths Around Us activity ideas in your Operation Maths book and/or the the Maths Around Us videos accessible at https://www.edcolearning.ie/

Dear Family, your Operation Maths guide to Chance

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

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

Dear Family, below is a brief guide to understanding the topic of number sentences & equations, 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 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.

Understanding Number Sentences and Equations

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
  • 4 + 2 = 5 + 1
  • 4 + 5 > 6 + 2
  • 5 + ☐ = 9
  • 14 – 🌳 = 8
  • y + 5 = 20

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.

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.

Now that you appreciate how confusing maths signs can be, don’t take it for granted that your child does, or will, understand 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, 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.

Practical Suggestions for all Children

  • Encourage your child to read aloud every number sentence. For example for 11 – 4 = 7 say “eleven subtract/minus/takeaway four equals seven”. Ask them to suggest a matching scenario/story eg “I had 11 sweets and I ate 4, now I have 7 left” or “I have 11 sweets and you have 4, so I have 7 more than you” (ie the difference between our amounts). Always read = as “is the same as” or “equals”.
  • Ask your child to suggest how to represent the various maths scenarios that you encounter, as number sentences, e.g. how to work out the cost of a number of some 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.
  • 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.
  • Whenever your child is working with word (maths story) problems at home, encourage them to show it as a number sentence or to make a drawing/diagram first, before they start to solve it.

Maths by Month – May (updated 2020)

A new month is just upon us, and as usual, this heralds the latest installment in this 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, to contribute to this effort in some small way, we have launched a new series of posts entitled Dear Family. Each of these posts, will focus on a specific maths topic, and provide practical suggestions as to how families can support their child’s learning, as well as 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 shapes and 3-D objects, some of which also feature in the plans for this coming month (see below). The next posts, currently in development, focus on the topics of number sentences and equations, money and chance.

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

Dear Family, your Operation Maths guide to 3-D Objects

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of 3-D objects. Also below, are a series of links to digital resources that will help both the children, and you, learn more about 3-D objects. 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

  • Naming shapes: 3-D is short for three dimensional, i.e objects with length, width and depth/height. In Operation Maths we refer to them as 3-D objects, so as to distinguish them from their flat, 2-D relations. 3-D objects can also be referred to as solid shapes and they include cubes, cuboids, spheres, cones, cylinders, pyramids, etc. Distinguishing between 2-D shapes and 3-D objects can be a bit confusing for both adults and children; for example, the shape of a real ball may be referred to as a circle, since, if a ball is drawn, or shown in a picture, then the flat, 2-D shape of the ball in the image is now a circle! But in reality, it is a 3-D object called a sphere. And a box is not a 2-D shape, it is a 3-D object called a cuboid, but the flat surface of a box is usually the 2-D shape of a rectangle or, sometimes, a square. So, if looking for 3-D objects at home, ask the children to examine and if possible pick up, actual objects, as opposed to flat representations of the shapes in a picture book or magazine.
  • 3-D Shape hunts: Play games like “I spy, with my little eye, something the shape of a cube, cuboid, sphere” etc. Again, be careful that you affirm with your child that it is the entire object that you are looking at, as opposed to just a surface or a flat face of the object.

Maltesers - Wikipedia

  • Sweet! A great place to find 3-D shapes is in treats and their wrappings or containers. Next treat time, look carefully at your Maltesers (spheres), Toblerone box (triangular prism), Smarties container and Lindor chocolates box (both hexagonal prisms), tub of Quality Street (octagonal prism) Starburst/Opal Fruits (cuboid), mini-rolls and hot chocolate powder (both cylinders) and wafer cones (cone, of course!)
  • Properties: Each family of 3-D objects also has properties or characteristics that make them different from other 3-D objects. In the younger classes, the children will be exploring whether a 3-D object can roll, stack, slide etc. When out and about or helping around the house, children can be asked to name the 3-D objects that are easier to stack on shelves in the shop, in the cupboard etc? What 3-D objects might roll off a shelf? As the children get older, they will be exploring properties such as the number of corners (also called vertices), the number and type of edges (straight or curved), and the number and type of surfaces (flat faces or curved surfaces). Through developing a better understanding of what makes an object that 3-D object, the children can start to group 3-D objects with similar properties or characteristics together.
  • Take it apart! 3-D objects and 2-D shapes, as mentioned earlier, are very connected. Another way that children can explore this relationship is to take apart examples of 3-D objects. Boxes are ideal for this, so, before you put your boxes in the recycling bin, ask your child to tear it open along an edge so as to open it out flat and identify the 2-D shapes that make it. This is referred to as the 2-D net of a 3-D object. Did they see the 2-D shapes they expected to see?
  • Play, play, play! Encourage your child to play and explore with 3-D objects as much as possible:
    • Lots of the toys that are aimed at preschool age children focus on 3-D shapes: wooden building blocks, shape sorter toys etc. Even older children can return to these toys and look at them in a new way to see what they can now discover and say about these shapes.
    • Magformers , Geomag and 3-D puzzles are examples of toys specifically geared towards the construction of 3-D structures. Other toys that can be used to create 3-D structures include Lego, K’nex, Mega Bloks, Plus-Plus and Stickle Bricks/Bristle Blocks.
    • Build anything! Use boxes and any objects from around the home to build, stack, etc. Without even realising it, the children will be exploring and learning about the properties of these shapes.
    • Solve 3-D puzzles. Perhaps you have a Rubik’s Cube somewhere around the house? Or look out for other 3-D puzzles like Rubik’s Cage, Soma cube or Tetris Shake. Any of these these type of puzzles are a very worthwhile way to spend time!

Dear Family, your Operation Maths guide to 2-D Shapes

Dear Family, given below is a brief guide to understanding the topic of 2-D shapes, 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 2-D shapes. 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 2-D Shapes

Why do children need to learn about shapes? Learning to recognise different shapes not only helps children learn about this maths topic, but, in the early years, it also develops their ability to recognise numbers and letters by their shape. This skill will also transfer to other signs and symbols, be they maths symbols such as +, =, <, > etc., or signs and symbols in the real world e.g. road signs, safety signs etc.

Naming shapes: 2-D shapes is short for two dimensional shapes, i.e. shapes with length and width, but not depth/height. Also called flat shapes, these include circles, squares, rectangles, triangles etc. 2-D shapes can be a bit confusing for both adults and children; for example, a real ball is not a 2-D shape, it is a 3-D object called a sphere, but if a ball is drawn, or shown in a picture, then the flat representation of the ball in the image is now a circle! And a box is not a 2-D shape, it is a 3-D object called a cuboid, but the flat surface of a box is usually the 2-D shape of a rectangle or sometimes a square. So, if looking for 2-D shapes at home, ask the children to examine the flat surface of objects and/or to look at the flat shapes in a picture book or magazine.

Properties of Shapes: 2-D shapes also have properties or characteristics that make them different from other 2-D shapes. A shape with three straight sides and three angles (also referred to as corners or vertices) is always a triangle…but as the children get older they will also realise that some triangles have three equal sides (equilateral), some triangles have only two equal sides (isosceles) and some have no equal sides (scalene). Through an understanding of what makes a shape that shape, the children can start to group shapes with similar properties or characteristics together. So, if exploring 2-D shapes, draw the children’s attention to properties such as the number and type of sides (equal, not equal, straight or curved), the number and type of angles/vertices (equal, not equal, right angles or not).

Children in the senior end of primary school will further classify shapes into named groups, for example, they will identify different types of triangles, polygons (any shape with straight, non-curved sides) and quadrilaterals (four sided shapes, quad = four) and explore the different properties (size/shape of angles, length of sides) that make each one unique. They will learn more detailed terminology about the parts of shapes, especially the parts of a circle. They will also be asked to solve various problems (for example finding the measure of an unknown angle or side) based on what they know already. This is preparing them for the type of geometry they will meet in second-level maths.

Practical Suggestions for Supporting Children

  • Shape hunts: Play games like “I spy, with my little eye, something the shape of a rectangle” etc. Again, be careful that you affirm with your child that it is the surface or face of, for example, the door, that is a rectangle, not the entire door (which is in fact another cuboid i.e. a 3-D object). Look out for 2-D shapes on posters, road signs, billboards, wallpaper and in picture books. With older children, encourage them to notice that while each shape group has a key feature in common, each individual shape is different; for example while every triangle must have 3 sides, they also can have different size angles and sides. Look around for different triangles!
  • Play, play, play! Encourage your child to play and explore with 2-D shapes as much as possible:
    • Make 2-D shapes with sticks, string, playdoh, pastry, creating imprints in sand, mud, pastry, etc. Use construction toys such as Lego, K’nex, Geomag and Plus-Plus to create 2-D shapes and then build them further into 3-D structures.
    • Draw 2-D shapes and cut them out, create pictures, patterns, designs etc. Perhaps you have a spirograph toy somewhere in the house? Dig it out and give it a spin (excuse the pun!).
    • Solve shape puzzles. One of these are tangram puzzles. This ancient Chinese 7-piece puzzle, provides an excellent way to develop a child’s ability to manipulate and visualise shapes. You can often buy reasonably priced plastic or wooden tangram puzzles in local book and toy shops. You can also print out a set of trangram pieces and use them to solve the numerous puzzles available on line. Or you can play an interactive tangram puzzle game.
    • Other very worthwhile shape puzzles include tetrominoes (like the Tetris game of old) and pentominoes. You can also download games, based on many of these shape puzzles to your device; just search your app store for tangrams, tetrominoes/tetris and/or pentominoes.
  • Programming If your child does programming, or is interested in trying it out, they could use a free programme such as Scratch to draw various types of 2-D shapes.

Dear Family, your Operation Maths guide to Capacity

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 capacity. Also below, are a series of links to digital resources that will help both the children, and you, learn more about capacity. 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

  • Where possible allow your children to have opportunities for “water play”; this can be during bath time, playing in the sink when the washing up is done, having tea-time with a play tea-set, playing outside with a basin of water and containers, etc. Sand play, if available, should also be encouraged as children explore with “pouring” sand from one container to another.
  • In school, the children are enabled to compare, estimate and measure capacity. You can reinforce this at home by asking the children to use their visual sense of capacity to compare and estimate which bottles, containers etc., hold more or hold less. Collect a selection of various types of bottles and containers and, if possible, remove any telling labels. Ask the children to line the containers up in order, starting with the one that they think holds the least. Fill this one with water, and then pour this water into the second container.
    • Does all the water fit? If no, then the first container holds more than the second container.
    • If yes, does the water from the first container fill the second container to the same level? Then they both hold the same amount.
    • Or is there space left at the top of the second container? Then it must hold more than the first container.
  • When estimating capacity, do the children realise that height and/or shape is not always indicative of capacity i.e. a taller but skinnier container may contain less than, or the same as, a shorter container.
  • When investigating capacity, try to conserve water; have a large basin handy, or do the water-pouring over a closed sink or bath so that the water can be reused. Why not even investigate the capacity of various containers as part of water play in the bath or sink?
  • Draw the children’s attention to capacity labels on bottles and containers, especially l for litres and ml for millilitres. Even children who may not yet know that there are 1,000ml in a litre, can examine labels and can use their number knowledge to identify the one which holds the most/least. If the item does not have a capacity label, does it have a label for a different unit of measurement and why is this? (e.g. perhaps g or kg for weight).
  • Is it good value? Keep a close eye on the capacity of various items when shopping (whether it be in the shops or online): while you’d expect that a 3l bottle of drink would be twice the price, or slightly less than twice the price, of a 1.5l bottle of the same drink, you would not expect it to be dearer – yet that can sometimes be the case! So involve the children in checking the capacity of items to make sure that you’re getting the best value for your money!
  • Find the items around your home that measure capacity (these are often called measuring instruments): kettles; liquid detergent caps and dispensers; medicine cups, spoons and syringes; buckets and basins; measuring jugs. Look carefully at the measuring scale, marked usually along the side, and get the children to try out these measuring instruments for themselves.
  • Involve your child in measuring capacity when cooking and baking. If using recipes, ask the children to calculate how much of each liquid ingredient would be required to make half, double, etc., of the amount/dish.
  • Enlist the help of older siblings if available. As they explain and support the younger members of the family, they will also be developing and consolidating their own knowledge and skills, especially communicating mathematically.
  • Draw the children’s attention to any other situation where capacity needs to be considered eg water conservation around the home, how much water we should drink daily, putting liquid detergent in the washing machine, the capacity of the household bins, the amount of rain forecast, recommended dosage for various medicines, buying enough paint for a particular room, purchasing fuel (eg petrol, diesel, home-heating oil), etc.

Maths by Month – April (updated 2020)

A new month is just around the corner, and as usual, this heralds the latest installment in this series of posts designed to explore the Operation Maths topics on a month-by-month basis.

This installment, however, is coinciding with a very turbulent and uncertain time in national and global history, as teachers and families around the country explore how best to continue to support children’s learning.

To contribute to this effort in some small way, we have launched a new series of posts entitled Dear Family. Each of these posts, will focus on a specific maths topic, and provide practical suggestions as to how families can support their child’s learning, as well as 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 first post in the Dear Family series focuses on the topic of weight, which all of the classes from third to sixth are likely to encounter in their Operation Maths books this month. Please feel free to share this post with members of your school community, whether Operation Maths users or not.

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.

Dear Family, your Operation Maths guide to Weight

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 weight. Also below, are a series of links to digital resources that will help both the children, and you, learn more about weight. 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

  • In school, the children are enabled to compare, estimate and measure weight. You can reinforce this at home by asking the children to use their outstretched hands to compare and estimate the heavier/lighter of any two items, from anywhere around the house. Do they realise that size is not always indicative of weight? i.e. a bigger item (e.g. beach ball) may be lighter than a smaller item (e.g. a book).
  • The children can then check their estimate by using a handmade balance, assembled quickly from a clothes hanger and two identical bags.
  • Draw their attention to weight labels on food packaging, especially kg for kilograms and g for grams. Even children who may not yet know that there are 1,000g in a kg, can examine labels and can use their number knowledge to identify the heavier/lighter item. If the food item does not have a weight label, does it have a label for a different unit of measurement and why is this? (e.g. ml or l for capacity).
  • Is it good value? Keep a close eye on the weight of various food items when shopping (whether it be in the shops or online): while you’d expect that a 4kg bag of potatoes would be twice the price, or cheaper even, than a 2kg bag of the same potatoes, you would not expect it to be dearer – yet that can sometimes be the case! So involve the children in checking the weight of bags and packages to make sure that you’re getting the best value for your money!
  • Involve your child in weighing and measuring when cooking and baking. Show them your kitchen/digital scales (if you have any); demonstrate how it works and get the children to try the scales out for themselves. If using recipes, ask the children to calculate how much of each ingredient would be required to make half, double, etc., of the amount/dish.
  • Do you have any other weighing scales at home? Bathroom scales, luggage scales etc? Allow the children to explore how they work and use them to measure the weight of the bags used by the household: school bags, handbags, rucksacks etc.
  • Enlist the help of older siblings if available. As they explain and support the younger members of the family, they will also be developing and consolidating their own knowledge and skills, especially communicating mathematically.
  • Draw the children’s attention to any other situation where weight needs to be considered: weight requirements for children’s car seats, weight restrictions on baggage with airlines, weight restrictions when posting letters and parcels, etc.
