Students learn how to rotate an object on a grid using a centre, direction and amount of turn. As learning progresses the centre is given as a coordinate pair and on a Cartesian axes.
The start of the lesson is used to recap the difference between rotational and reflective symmetry. The plenary challenges students to describe two different and equivalent transformations.
Differentiated Learning Objectives
- All students should be able to perform a rotation where the centre touches the object.
- Most students should be able to perform a rotation on a grid.
- Some students should be able to perform and describe a rotation on a Cartesian grid.
