Why is estimation an essential ingredient for learning maths? And what do so many resources typically get wrong about estimation? In this session, together we'll examine these questions and what it means for classroom practice. We’ll also consider how estimation allows us to benchmark ideas, refine our intuition and hone our focus. By uncovering great problems that use estimation, you'll have time to explore how these can act as a springboard into strengthening mathematical thinking, confidence and curiosity for all learners.
