Students learn how to enlarge shapes objects on a grid using a centre and scale factor. Learning progresses from enlarging shapes to a positive scale factor to fractional scale factors. More able students are challenged to describe as well as perform enlargements by finding the centre and scale factor.

The start of the lesson recaps describing translations using vectors. At the end of the lesson students are challenged to perform and describe enlargements on an isometric grid.

**Differentiated Learning Objectives**

- All students should be able to enlarge an object using a positive integer scale factor and centre.
- Most students should be able to perform and describe an enlargement to a positive integer scale factor and centre.
- Some students should be able to perform and describe an enlargement to a positive fraction scale factor and centre.
