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.
