2.18 Forming and Solving Equations GCSE PowerPoint Lesson

In this 19-slide lesson, students will learn how to form algebraic equations from real-life and mathematical word problems and then solve them to find missing values. The lesson begins with accessible problems involving solving for missing ages. Students will practise translating words into algebraic expressions and forming equations based on those relationships. The lesson then progresses to using the same skills to tackle geometric problems, where key information (such as angle facts, perimeter, or area) is used to set up and solve equations. Emphasis is placed on defining variables clearly, writing expressions from clues, setting up and solving the equations. This lesson supports key problem-solving skills and prepares students for applied algebra questions often seen in GCSE exams.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• One structured task to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential algebra concepts.
