In this video segment from Cyberchase Inez competes in a rollerblading competition against Rimm, a skater for Team Hacker. Just before Inez skates, Hacker changes the shape of the field. It still has the same perimeter, but it is much narrower. The CyberSquad decides to compare the perimeter and area of the three different fields they've had to skate on to make sure it is a fair competition.

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 we measure the distance around a football field we are finding its perimeter. When we measure the inside space of the football field, where the players actually play, we are measuring something totally different – the area. Do you think differently shaped fields can still have the same area? How is that possible?

Focus: As you watch this segment, look carefully at the pictures of the fields on the Skwak pad. Notice what measurements the CyberSquad chooses to make. What do the fields have in common? How are they different?
