2.17 Rearranging Formulae (Changing the Subject) Foundation GCSE PowerPoint Lesson

In this 25-slide lesson, students will learn how to rearrange formulae to make a different variable the subject. The lesson begins by revisiting inverse operations and the importance of maintaining balance when manipulating equations. Students will practise changing the subject in two and multi-step equations. Emphasis is placed on clear, logical steps and recognising the goal: isolating the required variable using algebraic manipulation.

For harder rearranging formulae where variable appears in more than one term, see higher algebra lesson.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• Two structured tasks to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential algebra concepts.
