When things are grouped in fives, we can count them easily going up in 5s.
Count the red spots.
We could count them one at a time, but that would take forever!
A much better way is to count them in 5s: 5, 10, 15, 20, 25
5 | 10 | 15 | 20 | 25 |
There are 25 red spots here.
Shall we have a go at some questions now?
