Teaching Tips: Pizza Toppings

Here are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.

What is Frame, Focus and Follow-up?

Frame: Suppose you and your two friends want to create a data display representing your favorite movies. Each of you must choose your top five movies (it's possible that some of your favorites might be the same). How might you display this data?

Focus: In this video segment, watch to see how Bianca organizes the pizza topping preferences. How does she show a topping that two of the friends want? How does she show a topping that only one person wants?

Follow Up: What do the intersecting areas on a Venn Diagram show us? Why does the middle section of Bianca's pizza have no toppings? When does it make sense to use a Venn Diagram to represent data?
