HYPATIAS Monday W2

LI Using reversing to solve mult/div problems


(Not always related to driving cars)

Sometimes it is easier to think of problems in a different way, as we know it doesn't change the equation if the question is written

9 x 7 = 56,    or    7 x 9 = 56

The answer is still 56, that is because each number has remained constant, or the same.

First, try this airplane problem.

Did you draw a range of plans for the aeroplane? If not, you definitely should have!
Moving on,


For example 1. 12

1. 2x6=12
2. 3x4=12
3. 4x3=12
4.1x12=12
5.12x1=12
6.6x2=12
7. 36÷4=9
8.36÷3=12
Please make sure you write the question and your answers in a neat organised table.
