Maths by Month – November (updated 2020)

Category : Uncategorized

Welcome to the third installment in this year’s Maths by Month posts, designed to explore the Operation Maths topics on a month-by-month basis.

As we journey together through on this school year, with all the uncertainties and possibilities that it may bring, rest assured that Edco Primary Maths and the Operation Maths blog will continue to support teachers, schools and families, along the way.

Central to this will be our Digging Deeper series of posts aimed at teachers and the ever-expanding series of Dear Family posts, aimed at parents and families, supporting children’s mathematical development at home. In addition, for teachers who want to find out more about the Operation Maths program, check out the About Operation Maths posts.

To access lists of relevant links and online resources, navigate towards the end of the relevant Dear Family posts, for a whole suite of suggestions, organised into approximate class levels.

Don’t forget that integrated with your digital Operation Maths pupil books, are numerous custom-made digital resources to support each maths topic. Just click any of the hyperlinks while viewing the digital book to bring you direct to the relevant resource.

TIP! If there are any digital resources for a particular page, they will also be briefly given and described in the footer of that page (both print and digital books). 

HINT: If you are new to Operation Maths this year or have changed class level, be sure to check out the Quick Start Guide to the Operation Maths books and the companion Quick Start Guide to the Operation Maths Digital Resources. Don’t forget that Operation Maths also has you covered for planning whether you’re teaching a single class or multi-class. 

Other suggestions for November:

  • The Bebras® Computing Challenge 2020 runs from 2nd to 13th November; it introduces computational thinking (i.e. the thinking skills behind coding and programming tasks) to students, by allowing them to solve interactive tasks online. The tasks can be answered without prior knowledge about computational thinking or information and communication technology. The aim of Bebras is to get students all over the world excited about computing. The challenges are divided into five different age categories from 8-18 years old. On the link above, both teacher and student can explore previous challenges and, even  if your class or school doesn’t register to take-part (which is free), the past challenges are very engaging and worthwhile to explore as a whole class or groups.
  • The 11 November marks the anniversary of the ending of the Great War, “the war to end all wars”, which is now typically referred to as World War 1. For 5th and 6th class teachers, who are planning to explore this topic in history, check out these Maths Activities from the Trench Brothers Education Zone.
  • Codes and code breaking were a very important part of warfare tactics during both World War 1 and 2. To find out more about the maths of code breaking click on the link.
  • Science Week 2020 runs from 8th-15th November. There are obvious links between Maths and Science, a fact which is being celebrated by the STEM (Science, Technology, Engineering and Maths) movement globally. Of the STEM areas, coding is one of the most exciting, not least of all to kids! And Operation Maths is the only Irish maths programme that has integrated coding activities via the Scratch Lessons for Operation Maths 3-6. Check out the scratch lessons that are included in the Operation Maths digital resources via your TRB or edcolearning.ie For infants, the Aistear Themes are an ideal way to explore STEM using a thematic focus (and lay the foundations for the development of computational thinking skills); consult the Junior and Senior Infants TRB for the monthly Aistear suggestions.

For some more primary-focused STEM activities, check out the links below:

Dear Family, your Operation Maths guide to Multiplication and Division

Category : Uncategorized

Dear Family, given below is a brief guide to understanding the topic of multiplication and division, 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 in the Operation Maths Dear Family letters for third to sixth class.

Understanding Multiplication and Division

Like addition and subtraction, multiplication and division is not just about multiplying and dividing to get a correct answer (although accuracy is always to be valued in maths); the focus is very much on understanding and visualising what is happening to the amounts/numbers, how they are changing, why they are changing and how the same calculation can be done in many different ways. This is often referred to as developing a child’s number sense.

In Operation Maths, the children are always encouraged to use materials and pictures, and to explore different strategies (ways) to get their answers. They are also encouraged to compare their strategies with the strategies of others, and to explain or justify why one way might be more efficient (faster and/or simpler) than another way.

From Operation Maths 3, possible thinking strategies for 2x, 5x, 10x.

In particular, the children are encouraged to refer to some key, benchmark facts, that, in turn, can be used to work out other facts. These include doubling and halving (which can be used to multiply and divide by 2, 4 and 8) and multiplying and dividing by 10, which in turn can be used to multiply by 5 (half 10 times the number) and multiplying by 9 (one group/set less than 10 times).

These benchmark facts (or friendly facts), combined with other strategies, ensures that the child develops both understanding of, and fluency with, the basic multiplication and division facts, which in turn cam be applied to more complex situations later, such as bigger numbers or fractions and decimals. Pictured below are examples of some useful thinking strategies for the basic multiplication and division facts.

From Number Facts 3 & 4, Edco, 2018

While multiplication and division are separate operations, they are also very closely related, being the inverse (or opposite) of each other e.g. 3 x 10 = 30, 30 ÷ 10 = 3, 30 ÷ 3 = 10. This is another strategy that the children can use i.e. think multiplication to do division, or vice versa. Beginning in third and fourth classes, the children will explore multiplication and division as being the inverse of each other, which will progress towards using the inverse (opposite) operation to check their calculations. 

Therefore, nowadays, there is less emphasis on just learning off “tables”, (i.e. memorising answers) and more emphasis on thinking strategies to use what they know, to solve what they do not know. 

Practical Suggestions for Supporting Children

  • Invite your child to help out with any opportunity to do multiplication and/or division at home, or when out and about, e.g. how much for 5 packets of the same sweets? If buying a multipack of anything, how much roughly for each item? etc.
  • Encourage your child to use strategies when multiplying and dividing and/or to explain their strategies. Ask your child to explain how they know, or worked out the answer.
  • “I don’t believe you…prove it!” When your child arrives at an answer, ask him/her to show you how they got an answer, to prove that that is the answer, and encourage them to think of other ways to arrive at the same answer. Are there ways that might be more efficient (better) than others?
  • Encourage your child to estimate. Estimation is a very important skill; this involves quickly getting a rough or ‘ballpark’ idea of the answer, e.g. 3 boxes of sweets at €4.79 each is just under €15 because €4.79 is almost €5. Encourage your child to quickly estimate answers e.g. How much, roughly, is that going to cost? Do we have enough money?

Other suggestions for October:

  • The October plan for third to sixth classes has deliberately allowed for a free week, to enable teachers to engage with Maths Week, held every year at this time. This year, Maths Week will run from 10-18 October, and while it will be a very different celebration this year, with no public gatherings, it will still be possible to participate virtually. So why not start to consider now, how your school might get involved in this national celebration of maths, and don’t forget to register your school at the link above. You can also follow the links in the site to find out more about Maths Art (which, coincidentally, links very well with October Operation Maths for 3rd and 4th classes i.e. tessellations in 2D shapes), Maths and history and code breaking. Check out their resource packs by class level also.
  • You could also make Maths Week become a game-themed week in your class. Teachers of third to sixth classes could use the Games Bank in the Operation Maths TRB. Teachers of infants to second classes can use any of the games listed in the short-term plans in their TRBs.
  • Another option for Maths Week, if you didn’t already do it in September, is Jo Boaler’s Week of Inspirational Maths. Click on the link for an overview of the activities in Week of Inspirational Math, and scroll down to the bottom of the page to access all the resources; Kindergarten roughly aligns with Infants, Grade 1 and 2 with 1st & 2nd classes, and Grades 3-5 roughly align with 3rd-6th classes.

Dear Family, your Operation Maths guide to Addition and Subtraction

Category : Uncategorized

Dear Family, given below is a brief guide to understanding the topic of addition and subtraction, 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 Addition and Subtraction

Of all the topics in primary maths, this is probably THE one with which the grown-ups feel most familiar…sure isn’t all just about either adding or subtracting (take away), plus (+) or minus (-), total or difference?

In some ways, it is, and in other ways, it’s not.

As the song goes, ‘it’s not what you do, it’s the way that you do it’ and the same is true for addition and subtraction at primary level; it’s not so much about getting a correct answer (although accuracy is always to be valued in maths) as understanding and visualising what is happening to the amounts/numbers, how they are changing, why they are changing and how the same calculation can be done in many different ways. This is often referred to as developing a child’s number sense.

In Operation Maths, the children are always encouraged to use materials and pictures, and to explore different strategies (ways) to get their answers. They are also encouraged to compare their strategies with the strategies of others, and to explain or justify why one way might be more efficient (faster and/or simpler) than another way.

In particular, the children are encouraged to refer to some key, benchmark facts, that, in turn, can be used to work out other facts. These include doubles (e.g. 4 + 4, 9 + 9 etc), near doubles (e.g. 4 + 5, 9 + 10 etc) and number bonds for 10 (e.g. 4 + 6, 9 + 1 etc). These benchmark facts (or friendly facts), combined with other strategies, such as count on (for adding smaller numbers eg 0, 1, 2, and 3), adding 10 and make a ten, ensures that the child develops both understanding of, and fluency with, the basic addition and subtraction facts, which in turn cam be applied to more complex situations later, such as bigger numbers or fractions and decimals. Pictured below are examples of some useful thinking strategies for the basic addition and subtraction facts.

While addition and subtraction are separate operations, they are also closely very closely related, being the inverse (or opposite) of each other e.g. 10 + 20 = 30, 30 – 20 = 10, 30 – 10 = 20. This is another strategy that the children can use i.e. think addition to do subtraction, or vice versa. Beginning in first and second classes, the children will explore addition and subtraction as being the inverse of each other, which will progress towards using the inverse (opposite) operation to check their calculations. 

Therefore, nowadays, there is less emphasis on just learning off “tables”, (i.e. memorising answers) and more emphasis on thinking strategies to use what they know, to solve what they do not know. 

Practical Suggestions for Supporting Children

  • Involve your child in any adding and subtracting that happens at home, or when out and about, e.g. buying tickets for the cinema, buying items of clothes, etc.
  • Encourage your child to use strategies when adding and subtracting and/or to explain their strategies. Ask your child to explain how they know, or worked out the answer.
  • “I don’t believe you…prove it!” When your child arrives at an answer, ask him/her to show you how they got an answer, to prove that that is the answer, and encourage them to think of other ways to arrive at the same answer. Are there ways that might be more efficient (better) than others?
  • Encourage your child to estimate. Estimation is a very important skill; this involves quickly getting a rough or ‘ballpark’ idea of the answer, e.g. €31 and €52 is roughly €80. Encourage your child to quickly estimate totals and differences, e.g. How much, roughly, is that going to cost? Do we have enough money? About how much will we have left?

Dear Family, your Operation Maths guide to Comparing and Ordering

Category : Uncategorized

Dear Family, given below is a brief guide to understanding the topic of comparing and ordering 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 comparing and ordering. 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 Comparing and Ordering

Comparing and ordering is probably something that happens a lot in any home already!

  • “She’s got more than me! That’s not fair!”
  • “I want to be first!”
  • “I want to have the biggest piece!”

In maths, comparing is when two items, amounts or portions are examined to see if they are the same (equal), and if not, which is the larger/has more and which is the smaller/has less. Statements can be made to show how the two relate to each other; for example they are equal (=), there are more bananas than apples (opposite); there are less pears than strawberries.

Initially, the children will be identifying which group has more/less, and which number is less than or greater than another number. Then, they will begin to describe the relationship in more detail e.g. there is one more banana than apples; there is one less pear than strawberries.

In second class, the children will begin to use mathematical symbols (inequalities) to show the relationship eg 5 > 4 (five is greater than four); 2 < 3 (two is less than three).

Once the children are comfortable comparing two items, amounts or portions, they will then be able to progress to ordering three or more, for example ordering four numbers, smallest to largest, or vice versa. Number word order is also an important aspect of this i.e. identifying the number that comes before or after another number.

Ordering also involves being able to use the ordinal numbers 1st, 2nd, 3rd, 4th, 5th…. and ordinal words such as first, second, third ….. and last.

Practical Suggestions for Supporting Children

  • The next time your child complains that somebody has got more than them, ask them to prove it! If it is sweets, can the child count the amounts to explain or justify that they do indeed have less than another? Or even when sharing out items like this, deliberately give more to somebody and ask your child(ren) to check if the amounts are all the same and, if not, to explain how the amounts are different. And what could be done to make it fairer.
  • When organising, tidying, sorting at home, ask your child to compare the groups of items they encounter. Ask questions such as:
    • “Which has more/less?”
    • “Which is larger/smaller?”
    • “Do you want more tomatoes or more grapes in your lunch?”
  • Try to incorporate ordinal number words such as first, second, third…last into your daily routine.
    • Who was first up out of bed? Who was second? Who was third? Who was last?
    • Who was first, second etc to be dressed, ready to go to school, finished homework etc.
    • When giving instructions: “First put on your socks, second put on your shoes, third put on your coat.”
    • When playing games discuss who will go first, second, third etc.
    • When standing in a queue talk about your position i.e. where you are standing.
  • Monitor your child closely when they start writing the ordinal numbers, and don’t take them for granted, as the abbreviation system is not always obvious:
    • Straightforward enough: fourth = 4th; sixth = 6th; seventh = 7th; tenth = 10th.
    • Less obvious: fifth = 5th; eighth = 8th; ninth = 9th
    • Tricky! first = 1st; second = 2nd; third = 3rd
  • Talk about the dates on the calendar. Say the ordinal number word clearly so that the child appreciates the difference in the sound of these numbers and the counting numbers eg seventh not seven.
    • “Your birthday is on the 3rd (third) of October.”
    • “We will be going back to school on the 6th (sixth) of January”
  • Play hand grab: Get your child to put their hand into some lego, marbles, or other similar items and to put the handful ‘grabbed’ out onto a table. You child can then repeat this, or somebody else can get a handful. Look at the two amounts on the table. Estimate which has more. Then check which has more by either counting or laying both sets of items out in two lines, side-by side, so that you can clearly see which line has more. You could also ask your child to count to find out how many more are in the longer line.
  • Play an ordering numbers game. Write down all/some of the numbers that your child knows, (eg 0-5 for junior infants, 0-10 for senior infants 0-20 for first class and any set of random numbers within 100 for second class), with each number on a separate piece of paper/post-it. Mix up the numbers and place them face down. Get your child to:
    • Pick up a number and say it.
    • Place all the numbers in order smallest to largest (variation: largest to smallest).
    • Say what number is missing, after you remove one.
    • Pick out 3 or three numbers and put them in order smallest to largest or vice versa
  • Play guess my number. Get your child to write down a number within their familiar numbers range (see above). Work out the number by asking questions to narrow the possibilities. For example, is it greater than 5? Is is less than 5? etc. Next round, you write down a number and your child asks you the questions.
  • You can also play any of the online interactive games below.

Maths by Month – September (updated 2020)

Category : Uncategorized

Maths by Month is back!

As we embark on this new school year, and with all the uncertainties and possibilities that it may bring, rest assured that Edco Primary Maths and the Operation Maths blog will continue to support teachers, schools and families, along the way.

Central to this will be our Digging Deeper series of posts aimed at teachers and the ever-expanding series of Dear Family posts, aimed at parents and families, supporting children’s mathematical development at home. In addition, for teachers who want to find out more about the Operation Maths program, check out the About Operation Maths posts.

HINT: To ensure you don’t miss out on any future 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:

To access lists of relevant links and online resources, navigate towards the end of the relevant Dear Family posts, for a whole suite of suggestions, organised into approximate class levels.

Don’t forget that integrated with your digital pupil books, are numerous custom-made digital resources to support each maths topic. Just click any of the hyper links while viewing the digital book (see example of purple icon below) to bring you direct to the relevant resource.

TIP! If there are any digital resources for a particular page, they will also be briefly given and described in the footer of that page (both print and digital books). 

HINT: If you are new to Operation Maths this year or have changed class level, be sure to check out the Quick Start Guide to the Operation Maths books and the companion Quick Start Guide to the Operation Maths Digital Resources
Don’t forget that Operation Maths also has you covered for planning whether you’re teaching a single class or multi-class. 

Other suggestions for September:

  • Check out the “Maths and me” attitudes questionnaire, situated after the last assessment in the Operation Maths Pupil Assessment booklet for 3rd to 6th classes. Suggest to the children that they fill this using a particular colour on one of the first days of the school year to be then revisited later in the year. At this point, the children can again record their attitudes in a different colour and reflect upon any changes they made, if any.
  • Maths about me: another great activity for the start of a new school year. The children write facts about themselves that are appropriate to their ability eg height, age, shoe size, telephone number, distance from school (use google maps), time that they get up or go to bed etc. This can be recorded on the inside front cover of the discovery book, filled in on a pre-made template from the internet, used to make a large class display or even become a more complex problem solving activity in the more senior classes.
  • The Math in Learning Names: Another one for kick-starting the year; make learning names easier (for both you as the teacher, and for the other students) with these quick and fast sorting ideas, which incorporate maths and language features, such as vowels, syllables etc.
  • Inspire your class for the year ahead: Most people have this belief that there is such a thing as a maths brain, a belief which Jo Boaler, among others, strongly challenges. Since 2015, in conjunction with her youcubed team at Stanford University, they have put together resources, videos etc for a Week of Inspirational Maths. They now have lessons and activities aimed at infants to 6th, as well as second level. Click on the link for an overview of the activities in Week of Inspirational Math, and scroll down to the bottom of the page to access all the resources; Kindergarten roughly aligns with Infants, Grade 1 and 2 with 1st & 2nd classes, and Grades 3-5 roughly align with 3rd-6th classes.
  • New year, new initiative! Number Talks is an excellent maths methodology that is gaining traction globally, and more recently, nationally thanks to the promotion of the PDST. Better still, the rationale behind it aligns itself very closely with the underlying principle of Operation Maths, that is teaching children to understand maths, not just do maths. To find out more about number talks and to access a whole suite of ready-made resources for all class levels just click on the link above.
  • Maths Week (10-18 October) will all too quickly be upon us! And while it will be a very different celebration this year, with no public gatherings, it will still be possible to participate virtually. So why not start to consider now, how your school might get involved in this national celebration of maths, and don’t forget to register your school.

We’re here to help!
If you have any questions on Operation Maths, Number Facts or anything related to primary maths over the course of the school year, please PM or contact Edco Primary Maths via Facebook and/or Twitter 


Dear Family, your Operation Maths guide to Data

Category : Uncategorized

Dear Family, given below is a brief guide to understanding the topic of data 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 data. 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 Data

Data, as the name suggests, is all about information, and in maths it is about organising information in such a way that it is easy to read and interpret. Most of us are quite familiar with information from surveys, voting etc., presented in graphs, charts and tables in various print and digital media. But graphing is only one part of the data presentation and analysis process, and this process is essentially the same, whether at the junior or senior end of primary school, or even at a more advanced level of statistics:

  • It starts when someone ask a question, that doesn’t have an obvious and/or immediate answer. This could be a question like who do most people intend to vote for in the next election or what is the favourite colour of a group of people or which sweet occurs most often in a box.
  • Information is then collected relevant to the question. This may be collected via a digital or face-to-face survey. It may be collected from a large or small representative sample of people.
  • This collected information or data is represented in a structured way that makes it easier to read. This might be a type of graph, pie chart or table.
  • This represented data is then examined and compared (analysed and interpreted) in such a way as to be able to make statements about what it reveals and, in turn, to possibly answer the initial question; if the question remains unanswered, it may be necessary to re-start the process again, perhaps using different methods.

In the senior end of primary school the children will encounter more complex data and charts/graphs, while also analysing data in more complex ways, such as calculating the average (also know as mean), in 5th & 6th class, and identifying the most frequently occurring value in a data set (also known as mode) in 6th class.

Practical Suggestions for Supporting Children

  • Let’s get organised! As mentioned earlier, data is all about organising information in an easy-to-interpret way. So any activities which involve sorting or organising can become a data analysis activity, for example:
    • What lollipop flavour/colour occurs most often in the bag (see image)? Ask your child to organise the lollipops in such a way that we can see the answer, without the need to count. This could be done with a box of wrapped sweets also, for example, Quality Street, Heroes, Celebrations etc. For more challenging questions, ask your child to tell you how many more/fewer of one type than another type.
    • What toy type do you have most of? When tidying up the toys, lay them out in rows alongside each other (parallel rows, similar to above), with the same type in each row. Of what toy type is there the most? The least?
    • Hat sort: Organise your hats into rows of winter hats and summer hats or hats with rims and hats without rims or even just according to colour. You can do something similar with other clothes types also.
    • You can also organise buttons or Lego pieces or building blocks in a similar way …. or any suitable material you may have at home.
  • Real-world examples: Anytime you come across any examples of the data process, share these experiences with your children. It could be completing a review (survey) for an online purchase or a holiday stay. It could be survey or election results you come across on the internet, radio or TV. If a graph is used, ask your child to tell you the type of graph it is and to tell you what they notice, or can tell, from the information shown.
  • League tables (soccer, GAA, rugby), are an ideal example of data presented in a table. Look at a table of results together, ask your child to interpret the information given, what it tells us, and what the various headings mean. Discuss an upcoming game: if your preferred team wins, how will that affect the table?
  • Planning a party and not sure what to do or where to go? Why not ask your child to survey his/her playmates with 3 or 4 possible options and then use the collated results to determine the destination?
  • Do a survey: You could do a traffic survey outside your house or a bird watch survey in your back garden. Or just encourage your child to come up with their own questions that they would like to answer. Survey your friends and family and then graph/present the collected information. Digital technologies (for example Microsoft Excel and Google Docs/Sheets) make it very easy to create a variety of very effective graph types.

Dear Family, your Operation Maths guide to Lines and Angles

Dear Family, given below is a brief guide to understanding the topic of lines and angles 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 lines and angles. The digital resources are organised according to approximate class level:

Understanding Lines and Angles

Line and angles is a strand unit in the Primary Maths Curriculum for 2nd class up. For most people, when they think about angles, they also think about degrees, for example a 90° (ninety degree) angle. Yet in primary school, we don’t introduce degrees, as a way to describe, measure and construct angles, until 5th class. So what are they doing before that?

Initially, children are exploring angles as ‘turns’ i.e. recognising angles in terms of rotation: quarter-turns, half-turns and full turns. The children explore this themselves by turning to show the different turns, in both clockwise (turning right) and anticlockwise (turning left) directions.

In school, the children will also be shown other real-world examples of angles, including angles made by the hands of a clock, by the blades of an open scissors, by a door opening and closing, etc. We also look at angles (or corners/vertices) in 2-D shapes, for example in rectangles and triangles… even the names of these shapes pay homage to the angles that made them what they are today! (triangle = tri (or 3) angle; rectangle = rect (right/proper) angle)

In third class, the children will begin to use the term right angle, as a more mathematically correct way to describe the quarter turn (when movement is involved) or square corner (when there is no movement i.e. the angle is static) that they met in second class. The children will also learn to identify and name a variety of angles: angles less than a right angle (acute angles), angles more than a right angle (obtuse or reflex, more than 2 right angles/a straight angle) and angles equal to 2 right angles (straight angle). Then, in 5th and 6th class, they will begin to use degrees to identify, measure and construct various types of angles. This requires the use of a protractor, from a maths set, and it is not the most obvious or straightforward tool to use, so plenty of practice is required (see video links below in the Digital resources section for 5th and 6th class).

You can’t have an angle without having at least two connecting lines, therefore lines are an integral part of this area of maths. Like angles, not all lines are the same and the children learn to recognise and describe lines as horizontal, vertical, oblique, parallel or perpendicular.

Practical Suggestions for Supporting Children

  • Ask your child to teach you about the angles and lines in your home. What different types of lines can be seen? What different types of angles can be seen? Can they name them?
  • Line Hunt: ask your child to show you some lines that they can see at home. Ask them to run their finger along the lines so they get a sense of the line’s direction and position.
  • Make a right angle finder: From a scrap piece of paper, tear out a large circular shape. Fold the shape in two, and then fold it in two again. The two straight edges/lines meet at a corner to make a right angle. Ask your child:
    • ‘Have you heard any other name for this type of angle?’ (square corner, quarter turn)
    • ‘Can you find any angles this size in this room? What are they called?’ (right angles)
    • ‘Can you find any angles greater than/smaller than right angles in this room?’
  • What’s in name? Write out your name in all capital letters. Name the different line types and angle types you can see. Are there any lines of symmetry in the letters? How many lines of symmetry and where? Click here to see some possible answers.
  • You gotta hand it to ’em! Look closely at your hand… can you see angles in the lines made by your fingers? Estimate the degrees and then click here to see possible answers.
  • 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 line and angle types.

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 counting and numeration. 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 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
