In this video segment from Cyberchase, the CyberSquad must build a raft to cross a river. The first raft they build floats, but there are gaps between the pieces of the raft that allow biting piranhas to jump through the holes. The CyberSquad uses their knowledge of tessellations to build a second raft that has no gaps or overlaps.

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: When a floor is installed in a bathroom or a kitchen it is often made up of tiles of the the same size and shape. The tiles fit together without any gaps or overlaps. Why would that be important? Fitting together shapes of the same size is called tessellating. Where have you seen examples of tessellations?

Focus: In this video segment, you will see the CyberSquad build a large square raft from smaller squares. Inez says that the big square raft is a tessellation. What does she mean? Why is the raft an example of a tessellation?
