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 see a series of inputs and outputs, we can find a pattern that makes us aware of a consistent rule. How do you go about deciding what the pattern and rule are? Do you ever use operations like addition and subtraction? Is it possible to use both in the same rule?

Focus: In this segment, the CyberSquad tries to figure out the frog’s new input/output pattern by experimenting with the buttons. Record the input/output data the CyberSquad discovers and see if you can figure out the new pattern.
