A complete, ready to teach lesson on the circumference and area of a circle for KS3 and GCSE maths (Foundation and Higher). 31 editable PowerPoint slides with teacher notes on every slide. The lesson builds step by step from the parts of a circle to exam style problems: Learning objectives (must, should, could) and a warm up on halving, squaring, square roots and rounding, with answers Key words: centre, radius, diameter and circumference, with a colour coded diagram What is π? Shown by unrolling the circumference against the diameter The formulas C = πd (or 2πr) and A = πr², and why area always uses the radius Circumference: worked examples from a diameter, from a radius and working backwards, then six “your turn” questions with answers Area: worked examples from a radius and from a diameter, answers in terms of π, and finding the radius from the area Practice set of six mixed questions, including a semicircle, with an answer slide Problem solving: how many turns a bike wheel makes in 1 km, and one large pizza or two small ones? Exam style question (4 marks) with a mark scheme Common mistakes, an exit ticket with answers, and a key points summary Every question has a worked answer slide, so it works for whole class teaching, cover lessons, intervention groups and revision.
