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. Each book is a stand-alone resource, so children can either work through them in order or focus on individual aspects of the subject. Together, the nine books support the whole of the Key Stage 2 maths curriculum, providing a solid foundation for success in maths. Number Patterns & Algebra meets the National Curriculum requirements for Key Stage 2 maths, and covers the following areas: factors, multiples, fraction sequences, prime numbers, odd and even numbers, negative numbers, Roman numerals, cube and square numbers, term-to-term rule, unknowns and variables, and simple algebra. This book develops skills in recognising and explaining number patterns and sequences. 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.
