I often have requests from parents as to the best approach they should take with their children when helping with homework.  This is a valid question, as using an ‘old’ technique might result in a correct answer, but it could also lead to quite a lot of confusion if the teacher at school is doing things differently!

Following are three videos that explain, using simple examples, the difference between what I learnt when I was at school and the new techniques used today.

Subtraction – counting forward to take away – what might seem like a mathematical oxymoron actually makes sense!

Multiplication using partitioning


Division using taking away – bear with me; it makes sense by the end!
