A full lesson on angles in polygons. Home in on the definition of a polygon and expel misconceptions surrounding the word polygon and properties of polygons. Teach exterior angles in polygons first as the majority of exam questions do not need students to have memorised the formula (n-2) x 180 and the majority of questions can indeed be answered without remembering this formula. I have provided some exam question practice using intelligent practice, leading children through scaffolded examples. There is also a short video explaining each of the slides and why they are there. Would suit a mastery curriculum and fit in with any of the White Rose Maths small steps.
