Gamma: The 3rd Book of Mathteasers is one of three question booklets aimed at advanced learners. The problems in this book are ideal for children in Years 6-8. Pupils who have already mastered the standard curriculum will find a welcome challenge in this series written by Tony Gardner. The questions have been designed to deepen pupils’ mathematical knowledge rather than accelerating them through topics. The books, similar to Maths – No Problem! Primary Textbook Series, follow the 2014 English National Curriculum.
