Watch: Counting in 2s
Let's begin with a practical exercise involving counting in twos.
Example 1
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.
Example 2
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 socks.
There are 2 socks in a pair.
Can you count how many socks are below?
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
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.
