Venn Diagrams are used in all subject areas to compare and contrast. The Button Box by Margarette S. Reid is a great book to read to students and introduce them to how to complete Venn diagrams based on attributes. In this activity, I have a double Venn diagram for younger students and a triple Venn diagram for older students as well as a sample page of buttons. When I use this book, I bring in the large bag of buttons I bought at the local discount store. Don't forget to address where to place the buttons that do not have any of the attributes given.
Venn diagrams are often included on state tests. This is a great cross-curricular activity!
