One of the hardest things to get children to do is explain how they did a sum. These two pages try to help with this, encouraging children to explain the decisions they make about:
which operation is involved in word problems
whether calculations can be done mentally or with pen and paper
how to explain and record the operations used.
Talking about what they do is vital in the internalisation of processes, which eventually become second nature.
These two pages can be found in our Year 4, Using and Applying Maths category.
