Students learn how to find the sum and difference of two algebraic expressions by expanding brackets. Learning progresses from working with linear to non-linear terms and writing the area of composite shapes as simplified algebraic expressions.

The start of the lesson recaps factorising and expanding a single bracket. The plenary challenges students to write the area of a composite shape as a simplified algebraic expression.

**Differentiated Learning Objectives**

- All students should be able to simplify the sum of two brackets with linear terms.
- Most students should be able to find the sum and difference of two or more brackets.
- Some students should be able to find the sum and difference of two or more brackets with non-linear terms.
