Fact familys

Fact families is a easy math strategy.

You use it to know other math questions by switching the number in the questions like 2x3=6 3x2=6.

To change the answer into bigger numbers you have to add a zero in to the first nuber number and it will be sixty if the answer is six and keep how much your multiplying the same.

Here are some examples

7x2=14             2x4=8            5x2=10           3x6=18

2x7=14             4 x 2=8          2 x 5=10         6 x 3=18

70x2=140         20x4=80       20 x 5=100    30x6=180

2x70=140         4 x 20=80     50x2=100     60x3=180
