For teachers
This GCSE Maths lesson teaches circle vocabulary. By the end, students should be able to identify and correctly name the parts of a circle - centre, radius, chord, diameter, circumference, tangent, arc, sector and segment - from a labelled diagram. It works through three worked examples and the mistakes examiners report.
