Developing the building blocks for mathematics. This book supports early years teachers and practitioners to enable children to build Strong Foundations in Mathematics. It focuses on children’s learning and development in mathematics in the critical reception year. It supports trainee teachers and early years students to reflect on their own mathematics learning and how this influences their teaching and subject confidence. It acknowledges the uniqueness of the early years and explores the mathematical pedagogies of the EYFS. Importantly, the book challenges the assumption that early years mathematics is ‘not proper maths’.
