*Compare the Calculations printable sheet*

There are four multiplication calculations hidden below.

Your challenge is to put them in order, from easiest to hardest. Try to do this without actually calculating each answer if you can.

Click on 'Show' to see them.

70 x 40

70 x 57

70 x 21

70 x 100

How did you decide the order?

You might like to do exactly the same with the set of four division calculations hidden below.

350 $\div$ 7

350 $\div$ 1

350 $\div$ 25

350 $\div$ 3

Create a set of four multiplications or four divisions yourself, which you think could be put in order from easiest to hardest.

Give them to someone else to order.

Do they agree with your final order? Why or why not?

You may find it useful to print off a sheet of the two sets of calculations. You could cut them up into two sets of four cards.
