In this video segment from Cyberchase, Wicked and Digit are following clues left by Motherboard to help them free the CyberSquad. To get the next clue from Grubby, they must use a fraction to describe their share of a box of worms. In doing so, they learn to identify the denominator as the number of parts that make up a whole and the numerator as their share of the parts.

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: If you bought a pack of gum with three pieces in it and ate two of the pieces, what fraction of the pack have you eaten? To solve this, you are finding a fractional part of a set. When you write the fraction, what does the bottom number, or denominator, mean? What does the top number, or numerator, mean?

Focus: As you watch this video segment, notice how Digit figures out what fraction of the box contains worms. How does he determine the bottom number of the fraction? How does he determine the top number?
