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? Or what is it about a circle that makes it a circle? Sometimes measuring helps with this process of defining a shape. Can you think of an example?

Focus:
As you watch this segment try to determine what the CyberSquad knows about circles that enables them to find the exact center of a circle. How does the CyberSquad use this knowledge to physically go about finding the center?
