This is a complete lesson on experimental and theoretical probability that looks at the difference between probabilities worked out theoretically, and probabilities found by carrying out an experiment. The lesson is designed with the new GCSE specification in mind.

- To compare experimental data and theoretical 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 ‘Experimental & Theoretical Probability’ lesson, including introduction, teaching content, individual activities, plenary and suggested support and extension activities
- Make a Spinner
- Student Worksheet on Experimental & Theoretical Probability
- True or False Cards
- Probability Fact Sheet
- Complete Solutions to all Questions
