Reversibility

WALT -  Use place value partitioning to solve multiplication problems

This week Room 1's Maths class are learning about Reversibility. Reversibility is a problem that you can solve easier. If we don't know our division it will be better if you reverse it and try our times table.

Example
81 ÷ 9 = ? Answer is 9
reversibility
9 x ? = 81
