Problem solving is a core element of teaching and learning mathematics, but also an area where teachers and children struggle. Designed to support both new and experienced teachers in guiding pupils through mathematical investigations, Problem Solving in Primary Mathematics provides practical guidance underpinned by the latest research and theory. It examines how individual pupils think and act differently, and how to promote independence and autonomy in the classroom. Offering a framework to help children through the times when learning is stalled, it supports teachers in identifying key points for intervention, helping children think and act independently, and moving learning forward.
