Designed to link research with real world classroom applications, the In Action series provides an accessible outline of key theories which teachers can then apply to their practice in their own unique settings. The writers of each of the In Action books are all either serving teachers or teachers who have taught for many years; this means the books' focus are grounded in the reality of teaching children in real classrooms. "Primary Maths: In Action provides a compelling vision for what a world-class Primary mathematics curriculum can look like. It also attends, with exquisite precision, to the small details of mathematics teaching. Fantastic for maths leaders and teachers alike."Gareth Metcalfe, Director of I See Maths
