This is a collection of 6 Venn diagrams. This is intended as an ice-breaker or warmup exercise: the task is to identify what defines each set.
For an extra challenge: look at my other files for a set of Edwards' Venn diagrams.
If requested: I can also supply these without a translucent background to improve image quality when printed in B&W. You'll probably want to remove (or skip) the answer key, but it is important to review it before you begin so you can give students hints as they get stuck. (Some of these can be very tricky!)
This document was created in Pixie. All the artwork is either from Pixie's clip art library or openclipart.org. If you want the Pixie document, you can download it here:
If you want to further develop this into another lesson/activity:
Ask students to make their own diagrams, then exchange with their peers and try to solve what each set is.
If you're using Pixie: you can use the extensive clip art library as you create new diagrams. If you don't have a lot of clip art available: just write words instead of providing illustrations. It's OK to have one or two empty spaces in a diagram, but if you have several you might want to rethink your categories or brainstorm new elements to add.
(If you would like further instructions on creating or solving these diagrams, feel free to ask.)
