The Right Angle - Evidence-informed approaches for great maths teaching

Great secondary maths teaching is not magic. It is built from deliberate, evidence-informed decisions that shape how students think, practise and improve. Structured around the linear flow of a typical maths lesson, this book explores the building blocks of effective classroom practice: purposeful beginnings and endings, clear modelling, responsive checking for understanding, rich questioning, independent practice and feedback that changes the next attempt. From qualifier questions to example problem pairs, each chapter connects practical strategies to research and contextualises them within the everyday realities of classroom teaching. Drawing on cognitive science, evidence-informed pedagogy and extensive classroom experience, The Right Angle asks two simple questions throughout: why does this matter, and what might it look like in practice?The result is a practical guide for maths teachers who want to make better classroom decisions, understand why effective strategies work and make every stage of the lesson count.
