Students learn how to create frequency trees from two-way tables and written descriptions. As learning progress students are challenged to calculate a probability from data presented in a frequency tree.

At the start of the lesson students recap entering data in a partially completed frequency table. The end of the lesson challenges students to complete a frequency with six different events.

**Differentiated Learning Objectives**

- All students should be able to complete a frequency tree from a two-way table.
- Most students should be able to record, describe and analyse the frequency of outcomes using frequency trees
- Some students should be able to record, describe and analyse the frequency and probability of outcomes using frequency trees.
