About This Year 2 Maths Topic

In Year 2, children move beyond simply counting objects one at a time. They begin to understand how our number system is organised into groups of ones, tens, hundreds and, where appropriate, thousands.

The most important idea is that the value of a digit depends on where it is placed. In the number 352, the digit 3 represents 3 hundreds, the digit 5 represents 5 tens and the digit 2 represents 2 ones.

Children also learn to recognise numbers in different forms. For example, 352 can be shown as a numeral, spoken as “three hundred and fifty-two”, built with place-value blocks, partitioned as 300 + 50 + 2, or located on a number line.

Parents can support this learning by using familiar objects, asking children to explain their thinking and encouraging them to show the same number in several different ways.

These activities support Australian Curriculum Version 9.0 content descriptor AC9M2N01 and its associated elaborations.

Learning Intentions

Children will learn to:

• recognise numbers to at least 1000;
• read and say two-, three- and four-digit numbers;
• write spoken number names as numerals;
• represent numbers using objects and place-value materials;
• partition numbers into hundreds, tens and ones;
• locate numbers on number lines;
• identify missing numbers in number sequences;
• use hundreds charts to recognise number patterns;
• compare and order numbers;
• explain the value of each digit in a number;
• understand the purpose of zero as a placeholder;
• group large collections efficiently into tens and hundreds.

Student Success Criteria

Key Vocabulary

Teacher Guide for Parents

When teachers introduce numbers to 1000, they do not begin by asking children to memorise long lists of numerals. They first help children understand how numbers are built.

At home, follow the same approach: build it, say it, write it and locate it.

1. Begin with Real Objects

Use objects that are easy to count and group, such as buttons, bottle tops, pegs, pasta pieces, blocks, craft sticks or coins.

Ask your child to make groups of 10. Then place 10 groups of 10 together to make 100.

This helps the child understand that:

• 10 ones make 1 ten;
• 10 tens make 1 hundred;
• 10 hundreds make 1 thousand.

2. Explain Place Value

Write a three-digit number such as 364. Point to each digit and explain:

• 3 is in the hundreds place, so it represents 300;
• 6 is in the tens place, so it represents 60;
• 4 is in the ones place, so it represents 4.

Then show:

364 = 300 + 60 + 4

Ask your child to build the number using place-value blocks, bundles of sticks or drawings.

3. Show the Same Number in Different Ways

Choose a number such as 428 and ask your child to show it in several forms:

• numeral: 428;
• number name: four hundred and twenty-eight;
• expanded form: 400 + 20 + 8;
• place value: 4 hundreds, 2 tens and 8 ones;
• materials or drawings;
• position on a number line.

This helps children understand that the representations look different but describe the same quantity.

4. Teach Numbers Containing Zero

Numbers containing zero are often difficult because children may ignore the zero or move the other digits into the wrong places.

Compare:

• 608 — 6 hundreds, 0 tens and 8 ones;
• 680 — 6 hundreds, 8 tens and 0 ones;
• 806 — 8 hundreds, 0 tens and 6 ones.

5. Compare Similar-Looking Numbers

Children may confuse numbers that use the same digits in a different order, such as 808, 880, 818 and 881.

Teach your child to compare from the greatest place value first:

1. Compare the hundreds digits.
2. If they are equal, compare the tens digits.
3. If they are still equal, compare the ones digits.

For example, when comparing 818 and 881, both numbers have 8 hundreds. The tens digits are different, and 8 tens is greater than 1 ten, so 881 is greater than 818.

6. Explain Number Lines

Before filling in a missing number, teach your child to identify the interval between the marked points.

Ask:

• What number does the line begin with?
• What number does it end with?
• How many equal spaces are there?
• Are the numbers increasing or decreasing?
• Are we counting by ones, tens, hundreds or another interval?

7. Explain Hundreds Charts

On a standard hundreds chart:

• moving one square to the right adds 1;
• moving one square to the left subtracts 1;
• moving one row down adds 10;
• moving one row up subtracts 10.

Cover parts of a chart and ask your child to work out the hidden numbers using neighbouring squares.

8. Teach Ordering Numbers

To order a group of numbers, compare the greatest place value first.

For example, to order 275, 725, 257 and 572:

1. compare the hundreds digits;
2. place the numbers into hundred groups;
3. compare the tens digits when hundreds are equal;
4. compare the ones digits if needed.

The ascending order is: 257, 275, 572, 725.

Recommended Teaching Sequence at Home

1. Count a small collection accurately.
2. Organise the collection into groups of 10.
3. Combine groups of 10 to make hundreds.
4. Build a number using hundreds, tens and ones.
5. Say the number aloud.
6. Write the numeral.
7. Write the number in expanded form.
8. Locate the number on a number line.
9. Compare it with another number.
10. Place several numbers in order.

Supporting Different Learners at Home

Children Who Need More Support

• begin with numbers to 100 before extending to 1000;
• use real objects and place-value blocks;
• use a labelled hundreds, tens and ones chart;
• work with one place value at a time;
• practise counting forwards and backwards by tens;
• use partially completed number lines;
• compare only two numbers at first;
• allow oral explanations before written answers;
• repeat activities with different numbers.

Children Ready for Extension

• work with numbers beyond 1000;
• use number lines with larger or less obvious intervals;
• identify numbers halfway between two labelled values;
• compare numbers containing several zero placeholders;
• create original hundreds chart puzzles;
• represent a number in several different ways;
• find multiple numbers that satisfy place-value clues;
• order larger sets of three- and four-digit numbers;
• explain and correct an intentionally incorrect answer.

Quick Parent Check

Use the following questions to check whether your child understands the main ideas.

1. Read the number 708 aloud.
2. Write “six hundred and forty-three” as a numeral.
3. Partition 526 into hundreds, tens and ones.
4. Build or draw 391.
5. Explain the purpose of zero in 605.
6. Write the number that is 10 more than 476.
7. Write the number that is 100 less than 832.
8. Order 808, 880, 818 and 881 from smallest to largest.
9. Complete a number line counting by tens.
10. Explain what happens when moving down one row on a hundreds chart.

A child shows secure understanding when they can give the answer and explain how they know.
