3.17 Volume of Prisms GCSE PowerPoint Lesson

In this 27-slide lesson, pupils will learn how to calculate the volume of a range of prisms by applying the formula volume equals the area of the cross-section multiplied by the length. They will begin with familiar shapes such as cuboids and progress to triangular prisms and cylinders, developing fluency in identifying the correct cross-section and using appropriate area formulas. To extend and deepen understanding, pupils will tackle more complex prisms including trapezium-based and L-shaped prisms, requiring them to break shapes into parts and work systematically. The focus will be on clear working, correct units, and interpreting diagrams accurately.

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 geometry concepts.
