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.
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.
A pair always has 2 things.
A pair of gloves is 2 gloves.
A pair of books is 2 books.
Practise counting up in twos from 0 to 40.
Remember, when counting in twos the last digit is always 0, 2, 4, 6 or 8.
