This activity is about the order of multiplying and dividing.
Notice that:
2 × 5 = 10 and 5 × 2 = 10
10 × 2 = 20 and 2 × 10 = 20
5 × 10 = 50 and 10 × 5 = 50
7 × 5 = 35 and 5 × 7 = 35
Multiplying can be done in any order.
You always get the same answer.
*****WARNING*****
Dividing is different.
10 ÷ 5 = 2 but 5 ÷ 10 = ½
They are not the same.
Dividing cannot be done in any order.
When we are dividing, we usually put the biggest number first and divide that by one of the other numbers.
The best way to get your head around this is to practise by doing some questions!
