Counting in steps of 2, 5 and 10
We can count in steps. Instead of going up by one, we go up by 2, 5 or 10.
Look at the step between two numbers. Then count on the same step to fill the gaps.
Key ideas
- Counting in 10s: 10, 20, 30 ...
- Counting in 5s: 5, 10, 15 ...
- Counting in 2s: 2, 4, 6 ...
Method. The numbers go up in steps of 5. Find the step first.

Watch out
Watch out. In steps of 5 the numbers end in 0 or 5. Do not write 42 in a count in 5s.
Exam tip
Grown-up tip. Count in 10s on the hundred square. Then count in 5s by touching the 5s and 10s.
