in class, we have been learning about doubling and halving numbers to simplify the numbers
when you do this strategy you look to see how you can make it easier by doubling and halving
1. 5x48= so first you can halve 48 which is 24 and double the 5 which is 10 and 24x10=240
2. 5x16=what you do is double the 5 and a half 16 so that is 10x8=80
and that is how you doubling and halving
