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: Many of us have certain routines we follow everyday. For example, when you get up in the morning, you might have a sequence of steps that you follow, such as shut off alarm clock, brush teeth, shower, get dressed, and eat breakfast. If you do those steps in the opposite order, that is called the inverse. What would be the inverse of addition? What would be the inverse of multiplication?

Focus: As you watch this segment, write down the steps that Bianca must follow once she is in the room with the video game eliminator. After she replaces the red crystal, write down the inverse of those steps and then watch to see if Bianca follows them. If she goes wrong, where does she go wrong?
