Mental Computation - Lower



Mental computation is the process of drawing on known strategies to solve an arithmetical problem. For example, to find 7 + 8 + 3, a strategic approach would be to change the order of the addition to 7 + 3 + 8 because you know that 7 + 3 makes 10, a rainbow fact, and that adding 8 to 10 is easy because 10 is a friendly number.

This book suggests activities that support mental computation by exploring the Natural Maths Strategies posters that can be printed from the accompanying CD. The posters present the early addition and subtraction strategies and lay the foundation for the understanding and later recalling of addition and subtraction facts. Knowledge of these strategies ensures that, in a situation where memory fails or the numbers are too large, the individual has the confidence to use mental computation to derive the answer.

This book is published by Blake and includes a CD with 18 posters of the mental computation strategies. It is available from:
