In this video segment from Cyberchase, the CyberSquad must make an antidote to a virus that has infected MotherBoard. One of the ingredients in the antidote is 2/8 of a Healing Stone. Matt and Digit locate the stone and notice that it is divided into four sections. Because they need to divide the stone into eight equal pieces, they learn about equivalent fractions.

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: Suppose you have an apple and you split it evenly with a friend so that you get half and your friend gets half. Then you take your piece and cut that in half. You eat those two pieces. Have you still eaten half of an apple? What other fraction could describe how much apple you have eaten? What equivalent fractions did you work with?

Focus: As you watch this video segment, notice how Digit gets the Healing Stone and immediately breaks it up into four equal pieces, or fourths. This is a problem because they need 2/8, not 2/4 of the stone. What does Matt do about this?
