Venn Diagrams - A Virtual Manipulative
This virtual manipulative represents three sets as overlapping circles. You can use it to represent set operations such as intersections, unions, and subsets.

The goal for each exercise is to shade the portion of the diagram corresponding to the given set.

You may begin by shading one or more entire sets (A, B, or C) and then clearing portions. When you have only the desired portion shaded, click the Check button.
