Key stage: 2
Subjects: mathematics, angles


In this activity, pupils use paired mirrors to investigate repeated reflections and the symmetrical properties of certain polygons.

Based on observations made about these symmetries, pupils will then look at how the mirors and reflections allow them to deduce the angles in various shapes.

Teachers should read through the activity ideas and make their own risk assessment for them before proceeding with them in the classroom.
