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:** How do you double an amount? For example if you have five pennies, how much would you have if you doubled that amount? How about if you doubled it again? What do you think would happen if you kept doubling that amount, say four or five times? How about twenty times? What mathematical operation are you using?

**Focus:** As you watch the video segment, think about how the penny amounts increase on the chessboard as the doubling occurs. Which wager would pay out more money, the five dollar wager or the doubling pennies?

**Follow Up:**Which wager amount was more? The five dollar wager or the doubling pennies? When we double an amount, what are we multiplying it by? After doubling a small amount, only nine or ten times, we can see that it increases dramatically. Why does that happen?
