# Number and Place Value

There are some tough challenges in the new Year 2 Programme of Study. Let’s begin by looking at ‘Number and place value’, which states:

Pupils should be taught to:

• count in steps of 2, 3, and 5 from 0, and in tens from any number, forward or backward

• read and write numbers to at least 100 in numerals and in words

• compare and order numbers from 0 up to 100; use <, > and = signs

• recognise the place value of each digit in a two-digit number (tens, ones)

• identify, represent and estimate numbers using different representations, including the number line

• use place value and number facts to solve problems.

Writing numbers to at least 100 in words is a real challenge which quite a few children will not be able to manage by the end of the year. The teen numbers are challenging, such as thirteen and fourteen, whilst when spelling whole tens, forty mysteriously loses the ‘u’.

A key idea in this category is partitioning numbers in different ways. For example:

24 can be split up or partitioned into 20 + 4 or 10 + 14 or even 12 and 12.

This is important to understand as it helps with written addition and subtraction in later years. Also it is important to begin to understand zero as a place holder; i.e. the 1 in 100 has a value ten times the 1 in 10, with the zeros being used as place holders.

Counting in multiples of 3 is a new target, introduced to help later with understanding the concept of a third.

The ‘more than’ and ‘less than’ signs are introduced for the first time; terms which in the past were introduced much later.

We have a great selection of worksheets on all these topics, so why not take a closer look?

## Counting on and back

This covers domain reference 2N1: count in steps of 2, 3 and 5 from 0 and in tens forward or back.

Counting forms a major part of Year 2 maths, including counting on in threes, fives and tens up to at least 100. Number grids and squares are often used to help with counting and positioning numbers.

## Reading and writing numbers

This covers domain reference 2N2a: read and write numbers to at least 100 in numerals and in words

## Ordering numbers

This covers domain reference 2N2b: compare and order numbers from 0 up to 100; use <, > and = signs.

Children will be expected to order numbers up to 100 and use the more than and less than signs.

## Place value and partitioning (100s 10s and 1s)

This covers domain reference 2N3: recognise the place value of each digit in a two-digit number (tens and ones) and 2N6: use place value and number facts to solve problems.

Understanding place value is the key to working with larger numbers. Bar models, abacuses and place value grids all help with this.

## Number lines

This covers domain reference 2N4: identify, represent and estimate numbers using different representations, including the number line.

Number lines are a great resource to help with counting and estimating.

## Estimating

This covers domain reference 2N4: identify, represent and estimate numbers. Being able to estimate a small amount is an important skill for Year 2 children.
