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: When someone says that they made 50% of their free throws in a basketball game, what do they mean? Is there a fraction that would mean the same thing? If you shot 100 free throws and made all 100, what percentage would you use to describe how successful you were?

Focus: As you watch this segment, you’ll see how the CyberSquad compares the Squitters' jumps. Use a paper and pencil to write down the data the CyberSquad has collected. How did they convert all of the fractions into percentages? Notice what Matt says the word “percent” means.
