This little book contains the answers to all the seven Mental Maths books by Anita Straker. The answers to Mental Maths Starter Book and Mental Maths 1–4 are also given in the accompanying teacher’s books, the answers to Mental Maths 5 and 6 are given only here. However, for the convenience of teachers who may be using two or three of the books at the same time to suit the needs of their more and less able pupils, all the answers have been collected together. The new national curriculum gives a high profile to mental maths. This book gathers together the answers to all the seven Mental Maths books. Teachers can give this book to children to mark their own work.
