In this video segment from Cyberchase, the CyberSquad has to help Shari Spotter make a batch of Cosmic Crumpets in order to give the masters at Frogsnorts their power. The recipe they have is for four crumpets, but they need to make eight crumpets. Everything in the recipe has to be doubled, including some tricky fractions which Shari and the CyberSquad find they must convert from improper fractions to mixed numbers.

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: Fractions usually describe amounts that are less than one whole. Are there any fractions you know that describe amounts that are more than one whole? Sometimes you may see a fraction that has a larger numerator than its denominator. This is called an improper fraction and represents a quantity larger than one whole. It can be converted to a mixed number, which includes a whole number and a fraction together.

Focus: In this segment, the CyberSquad has to double a recipe that includes fractions of cups. Notice which fraction gives them the most trouble when they double it. Why do you think this fraction is so hard for them to deal with? Watch how Digit helps the rest of the squad convert it to something that is easier to understand. He uses the fraction 4/4. What is 4/4 the same as?
