Venn Diagrams are great for comparing and contrasting, and I love to use them for parallel characters. Then one day I wanted to compare two parallel characters and a public figure from real life. Well, invention is the mother of necessity. The Super Venn Diagram uses three squares (I prefer squares to circles to make writing information easier) overlapping each other so that two characters can be compared or so that all three can, still allowing space for contrasts. Of course, why stop there? The Super Duper Venn Diagram uses four squares to compare and contrast. Use this as a way to really make your students think "inside" of the box!
