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: Where have you seen percentages used? What does it mean to consider 50% of something? What about 10% of an amount? If you had 50% of a dollar, how much money do you have? How about if you had 10% of a dollar?

Focus: Watch the steps the Answer Man takes as he calculates 15% of $15.45. Use a paper and pencil to work along with him and follow the steps.  Does the answer make sense? How do you know?
