Venn Diagrams Challenges • Describe your strategy for filling in the regions • Which

Venn Diagrams Challenges • Describe your strategy for filling in the regions • Which was the easiest region to complete, and which was the hardest? • Which region has the most possible examples, and which has the fewest? • If you think it is impossible to find an example for a particular region, convince me why • What would you change a circle label to, to make the task easier/harder • Create your own Venn Diagram on this topic where it is possible to fill in all the regions • Create your own Venn Diagram on this topic when it is impossible to fill in just 1 of the regions. How about one where it is impossible to fill in 2, 3, 4, etc regions?
