In this lesson

In this video you'll learn about three-set venn diagrams for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to interpret worded information about three overlapping groups to complete a three-set Venn diagram starting from the centre outward, and use n(A) notation to state the number of elements in a set or region.

For teachers

This GCSE Maths lesson teaches three-set Venn diagrams, element counts and n(A) notation (Higher). By the end, students should be able to interpret worded information about three overlapping groups to complete a three-set Venn diagram starting from the centre outward, and use n(A) notation to state the number of elements in a set or region. It works through two worked examples and the mistakes examiners report.
