Students learn how to use the length, area and volume scale factors for similar shapes.

As learning progresses they apply these relationships to calculate missing dimensions for a range of 2D and 3D shapes.

**Differentiated Learning Objectives**

- All students should be able to use the length and volume scale factors in similar 3D shapes.
- Most students should be able to use the length, area and volume scale factors in any similar 2D or 3D shape.
- Some students should be able to use the length, area and volume scale factors in any similar 2D or 3D shape with algebraic dimensions.
