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: Let’s say you want to create a special outfit. You have three different color ties, three different color shirts and two different color pants. How many outfit combinations can you make? How can you find all the possible combinations and be sure you ahave not left out any possible combinations?

Focus: In this video segment, you will see the CyberSquad trying to turn off a force field. In order to do that, they must find the correct combination of switch, lever and button. How do they organize the information they have so that they are sure they try every possible combination? What do trees and branches have to do with the way they organize their information?
