In this video segment from Cyberchase, Inez and Digit are attempting to gain access to a machine in order to save Sensible Flats from disaster. First, they must balance a scale to get the correct numeric access code. In order to do that they have to balance a scale using four weights on each side. They soon learn that adding or removing the same weight from each side does not upset the balance of the scale.

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: If you were helping younger children to play on a seesaw and there were three children of approximately equal weight on one side and only one child on the other side, how many more children would you put on the lighter side in order to get it to balance? What if one side had three children and the other side had four children? What would you do then to make the seesaw balance if there were no other children around?

Focus: As you watch, notice which numbers Inez and Digit put on each side of the scale to make it balance. When Inez realizes there are more weights than there are numbers on the machine, what does she do? How does she keep the scale balanced?
