3.2 Symmetry GCSE PowerPoint Lesson

In this 28-slide lesson, pupils will explore the two main types of symmetry in 2D shapes: lines symmetry and rotational symmetry. They will learn how to identify and draw lines of symmetry in regular and irregular shapes, and how to determine the order of rotational symmetry by rotating shapes around their centre. Pupils will use tracing, mirror lines, and rotation techniques to develop their spatial reasoning and visual accuracy.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• Three structured tasks to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential geometry concepts.
