Stem and Leaf Plot

Stem and Leaf Plot is a completely interactive lesson designed for learners taking GCSE (1-9).

Learning Objectives:

1. to be able to draw an ordered stem and leaf plot for numerical data;

2. and use stem and leaf plots to calculate mean, median, mode, and range.

Teachers can use the lesson for whole-class teaching. Learners can also use it at home for practice and revisions.
There are lots of drag and drop activities as well as interactive worksheets with instant feedback.

The lesson contains 35 interactive slides in stunning design and dynamic graphics that will engage your learners. A free 4-page worksheet is also included with answers.
