Why Lesson Planet?
Elementary schoolers engage in a game of logical reasoning called Secret Sort. A Venn diagram is used as a way to sort objects. This resource would be a great way to introduce the Venn diagram (maybe the most famous, and most-useful graphic organizer ever invented) to your charges. The game is clearly explained, and it should lead to an exciting math lesson. A resource link is embedded in the plan that allows access to more games like this one.
