In this video segment from Cyberchase, the CyberSquad must feed Cerberus, the three-headed dog of Greek mythology, in order to escape. The problem is that the dog has three heads and the CyberSquad only has two apples to split between them. It is up to the CyberSquad to figure out how they can divide their apples evenly among Cerberus' three heads.

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: Sharing an amount of something equally is not always easy. Can you think of a time when you have had to divide up something to be shared among a group of people? Sometimes when you share things you have to deal with both whole and fractional parts. Can you think of an example when you might have to do this?

Focus: Watch and see how the CyberSquad divides the two apples into equal shares. Notice how their problem-solving process begins with Matt’s statement about what they would do if they only had one apple. Think about how this idea helps them solve the problem. Does the CyberSquad use fractions? Do they use division? How?
