## Counting in twos

Here is number 7 on a number track.

How much is 2 more than 7?

How much is 2 less than 7?

9 is 2 more than 7.

5 is 2 less than 7.

Here is number 16 on a number track.

How much is 2 more than 16?

How much is 2 less than 16?

18 is 2 more than 16.

14 is 2 less than 16.

## Counting in pairs

Here is a pair of shoes.

There are 2 shoes in a pair.

Here is a line of pairs of shoes. There are 7 pairs.

How many shoes are in this line?

Count them in twos:

2, 4, 6, 8, 10, 12, 14.

## Top tip

Instead of counting up in twos, you can **multiply by 2**, which is a more efficient way of doing the same calculation.

Counting in twos gives you the two times table.

So, 7 pairs of shoes is the same as 7 x 2 = 14 shoes.

## Remember

A **pair** always has 2 things.

A pair of gloves is 2 gloves.

A pair of books is 2 books.

# Practise

## Activity 1

Practise counting up in twos from 0 to 40.

0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 |

22 | 24 | 26 | 28 | 30 | 32 | 34 | 36 | 38 | 40 |

Remember, when counting in twos the last digit is always 0, 2, 4, 6 or 8.
