Maths Venns is my collection of Venn Diagram activities covering many mathematical ideas. Students must think hard to find examples that meet different combinations of criteria in order to complete the diagram. Are some regions impossible to fill, or have students simply not found an example yet?
You can search for different topics using the Topics menus above, and you can find out more about Maths Venns on this page.
I have written two books about my use of these types of activities.
