Reversibility Strategy

WALT: Use place value partitioning to solve multiplication problems.
Today in class I learned that when you have a problem that you can't solve because its hard or its complicated, try using reversibility. Example:
24 divided by 4 = ?
4 x __ = 24
If you don't know what make 24. Maybe you should try time tables that make 24!
Try your 8 times tables. 8 x 4 = 24, there you go your answer is 8.
So that is 1 way you can solve a problem!
Reversibility is an easy way to solve a problem.

  1. Hi Lotu, it's great to see you understand the reversibility strategy. This is a strategy I use all the time with division problems.
