2.10 Factorising Difference of Two Squares PowerPoint Lesson

In this 20-slide lesson, students will learn how to identify and factorise quadratic expressions that are the difference of two squares. They will explore the structure a^2−b^2 = (a+b)(a−b)and practise applying this identity to both numerical and algebraic expressions. The lesson will also include recognising when an expression is not a difference of squares and how to simplify before factorising where necessary. 

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.
