Sharing My Learning Using Equal Addition

In Te Ngahere for the past week we have been learning to evidence our Maths.

I had to explain my knowledge of Equal Additions. Equal Additions is good

strategy to use for subtraction.The thing I found easy in this is balancing the numbers out. What I found hard

was trying to explain how and what to do in each step.

 

Have you ever had to evidence you math work?
