When things are grouped in tens, we can count them easily going up in 10s.
Count the eggs.
We could count each egg, one at a time, but that would take forever!
A much better way is to count them in groups of 10, as you can see below: 10, 20, 30, 40, 50.
10 | 20 | 30 | 40 | 50 |
There are 50 eggs in total.
How about if you wanted to know how many fingers were being waved in the air by 6 people?
How many fingers does each person have on their hands (if we include the thumbs!) They have 10, of course.
So, we count up in 10s until we've counted 6 people: 10, 20, 30, 40, 50, 60.
So, there are 60 fingers being waved in the air!!
Shall we try some questions now?
