Our Goal is to use the Doubling and Halving strategy to solve multiplication problems.
Here is an example: Let us say that we have this question: 56 x 8. We could either half 56 and double 8, or the other way round. Today, I am going to double 56 and half 8, which makes our question 112 x 4. That equals 448.
I hope you learn something from this post.
Maybe you could try making a question of your own?
Hi Gus,
ReplyDeleteGood job at explaining doubling and halving. I like using this strategy especially when the questions are a bit harder. I am going to show you how I would use doubling and halving for this equation - 16x20
I would double 16 and make it 32 and halve 20 and make it ten.
The new equation will now be 32x10=320.
Hello Gus, I liked your examples of Doubling and Halving! I have a question... Did you have fun doing this?
