In this open ended maths lesson, learners explore a sequence of gradually larger shapes and consider what mathematical questions they can ask about them. What is the same and what is different about a group of triangles, and how can they be drawn accurately. What measurements make an impossible triangle, and can students work out which triangles come next in a sequence? This KS4 lesson also gives students the chance to use Cosine.
