IALH: To use Proportional Adjustment.
Today I'm going teach you how to use this Strategy for a multiplication problem. And if you're wondering this level 3/4 maths.
Portional Adjustment is the same thing as Doubling and halving . 
But we use Proportional adjustment for Multiplication.

So the Equation is 
5 x 14 =
So we want to double the 5 and half the 14. 
Now the equation will look like this.
10 x 7
Now you can solve it
=70

14 x 5 = 70
7 x 10 = 70
