Venn diagrams are not taught well anywhere.
With little effort, these diagrams can be brought to life with beauty and by going beyond that little 3 circle Venn diagram. At the very least a teacher should end a lesson on the three circle Venn diagram with a question: "I wonder if this is possible with four circles?"
But we can go much, much further... and the puzzle sheets created below are designed to get you there 😉
"Venn for Polygons" is a highly engaging puzzle that gives students ages 8+ practice with properties of polygons. All edges are the same length unless they are obviously different lengths. Thanks to student Calvin Chan for finding a shape that was a little wonky 😉
"Mishap at Venn Zoo" is a full presentation of a polyomino variant that includes rotational symmetry. This is good for students as young as 8 or 9.
"ToothPick Polygons" has got a tough second question, but the first part is as easy as "Mishap at Venn Zoo."
