This is a complete lesson on relative frequency and expected frequency that looks at how to calculate the relative frequency of an event and the expected frequency of the event for a given number of trials. The lesson is designed with the new GCSE specification in mind.

- To understand and use relative frequency.
- To find expected frequencies based on 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 ‘Relative Frequency & Expected Frequency’ lesson, including introduction, teaching content, individual activities, plenary and suggested support and extension activities
- Student Worksheet on Relative Frequency & Expected Frequency
- Probability Fact Sheet
- Complete Solutions to all Questions
