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: Sometimes when we observe an activity we collect data to try to better understand what is happening. For example, a gardener may experiment by using different amounts of fertilizer on tomato plants. What kind of input and output data might the gardener record? What kind of patterns might the gardener look for in the results of this experiment?

Focus: As the CyberSquad tries to figure out how to control Hacker’s frog, they begin to experiment by pushing the buttons on the side of the frog and recording the results. As you watch this segment, record the input/output data to see if you can describe the pattern they find.
