In this video segment from Cyberchase, Matt, Digit and Slider must create an exact copy of a large ring in order to activate a powerful force and foil Hacker. To make sure the copy they make is perfect, they have to know what the “radius” of a circle is and figure out a way to carefully measure it.

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: All shapes have certain features or properties that help us define them. For example, how do we know when a four-sided shape should be called a square and not a trapezoid? What is it about a circle that makes it a circle? Sometimes measuring helps with the process of defining a shape. Can you think of an example?

Focus: As you watch this segment, ask yourself, “What feature or property of a circle helps Matt, Digit and Slider figure out how to create the exact copy of the ring they need? Was measurement involved?"
