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: Jackie says that "speed means how far you go in a certain amount of time." Does that definition make sense? When someone says the speed of a car is 50 miles an hour, what exactly does that mean? How far would a car traveling that speed go in three hours?

Focus: In this segment, watch to see how the CyberSquad use the information they gather about how far each broom travels in five seconds to figure out the distance each broom travels in one second. What computations do they make? Use a paper and pencil to write down the steps of their process.
