This is a complete lesson on sample space diagrams that looks at how to find all combinations of outcomes for pairs of events by drawing sample space diagrams, and using these to find probabilities of the combination of events. The lesson is designed with the new GCSE specification in mind.

- To list all outcomes for single events and for combined events systemtatically.
- To draw sample space diagrams and use them for finding simple probabilities.

This pack is designed for GCSE higher or foundation tier students. It could also be used with Key Stage 3 students.

Included in this download are the following:

- Full lesson plan for the ‘Sample Space Diagrams’ lesson, including introduction, teaching content, individual activities, plenary and suggested support and extension activities
- Example Sample Space Diagram
- Student Worksheet on Sample Space Diagrams
- Spot the Mistakes Plenary
- Probability Fact Sheet
