2.67 Harder Algebraic Negative and Fractional Indices Higher IGCSE PowerPoint Lesson

In this 37-slide lesson, pupils will build on prior knowledge of index laws to simplify and solve more complex expressions involving negative and fractional indices. The lesson begins with solving equations where all terms are rewritten using the same base number, reinforcing core index laws. Pupils will then simplify expressions that combine numeric and algebraic terms with fractional and negative powers, using their calculators effectively to evaluate numerical components. Challenging examples and exam-style questions will stretch pupils' fluency, accuracy, and algebraic reasoning.

This lesson is for the higher tier only.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• Three structured tasks to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential algebra concepts.
