Lesson details
Key learning points
- Congruent shapes can be used to investigate rotational symmetry.
- The centre of rotation is the centre of the shape.
- You must be careful not to count the starting point twice.
Keywords
Rotational symmetry - Rotational symmetry describes when a shape appears the same after some rotation. The order of rotational symmetry is the number of times the image appears the same as the object in one full turn.
Common misconception
When rotating a shape to count its order of rotational symmetry, pupils may count the starting position twice: once at the start and then again at the end of the full turn.
Encourage pupils to be consistent with when they count the starting position, either always counting it before they begin rotating the shape or always counting it at the end of the full turn.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
