Students learn how to solve a simple equation using the balance. To do this they are taught how opposite functions are used to keep an equation balanced while it is rearranged.

At the start of the lesson students use mental methods to solve simple written problems. In the main part they learn how to use the balance method to solve a one step equation. The plenary is used to assess progress against each of the differentiated learning objectives.

**Differentiated Learning Objectives**

- All students should be able to recognise inverse operations such as + / - and × / ÷.
- Most students should be able to solve a single step equation using the balance method.
- Some students should be able to set up and solve an equation using known facts.
