Doubling And Halving

 In class, we learned a new strategy called Doubling and Halving hji

When you do this strategy you look at the .............x......... then you have to halve the one that is gonna make it easier and the other you double.

.5 x 16-

a) I could double .5 and halve 16 = 1 x 8=8 

b) OR could halve .5 and double 16 =.25 x 32= 8

The easier way is A because it is more accessible during times

                                                                                                                                                                        

6 x 3.5

a) double 3.5 and halve 6= 7 x 3= 21

b) double 6 and halve 3.5= 12x 1.75=21

The easier way is A because  it makes it easier to times
