Understanding Maths is a series of topic-based study books for children in Key Stage 2, providing rigorous practice of key subject areas. Each topic contains a concise summary of the information required by the National Curriculum, making the series ideal for use as preparation for the Key Stage 2 tests.

Together, the nine books support the whole of the Key Stage 2 maths curriculum, providing a solid foundation for success in maths. Problem Solving meets the National Curriculum requirements for Key Stage 2 maths, and covers the following areas: choosing operations, solving word problems, number puzzles, scaling, time, large numbers, negative numbers, square numbers, shape puzzles, money problems, fractions, decimals, percentages, ratio and the distributive law. This book develops strategies for solving different maths problems, from deciphering the question to deciding on a solution. Key features of Understanding Maths include: an 'Explanation' to introduce each topic; activities to consolidate and revise knowledge and skills; thought-provoking facts to foster a love of learning beyond the National Curriculum; regular 'Progress tests' and a 'Final test' to track children's development
