Five pages that take the Venn diagram to three circles. Pages 1 and 2 sort sixteen numbers from a number bank, two in each of the eight parts, with the first number done as an example. Pages 3 and 4 read diagrams that show how many children are in each school club and play each sport, with six questions each: only one, exactly two, all three, none, and how many in all. Page 5 sorts twelve numbered shapes by whether they have 4 sides, are shaded, and have a square corner.
Before page 1, test one number aloud against all three rules: Is 21 odd? Is it a multiple of 3? Is it greater than 15? Three yes answers put it in the very middle. Show how each "no" moves the number out of that circle. On page 3, have students shade a whole circle with a pencil before adding its parts, so they see that the art club includes four numbers, not one.
Pick three questions about your family, like "Wears glasses?", "Likes pizza?" and "Has a pet?", and sort everyone into a three-circle diagram drawn on paper. Then ask who is in all three circles and who is in none.
