In this video segment from Cyberchase, the CyberSquad must divide up thirty-five pieces of rock candy evenly among seven gargoyles in order to stop Hacker’s control over the gargoyles. Jackie suggests that they figure it out by sharing the pieces of rock candy in rounds, but Inez has a better idea. She thinks that using numbers will allow them to solve the problem faster.

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 had a bowl of forty cherries and there were ten people who wanted to share the cherries equally, would you have to physically count out the cherries for each person? What would be another way to make sure there were fair shares? What mathematics would you use?
Focus: As you watch this segment, you will see how the CyberSquad quickly divides the pieces of rock candy into even groups. How do they manage to create the fair shares without actually having to count out the rounds?
Follow Up: How did the CyberSquad create the fair shares of rock candy for the gargoyles? How did they start? What mathematical operations did they use to insure that there were fair shares? How does the idea of "rounds" relate to multiplication?
JACKIE: Hi! Remember me?
HAROLD: Yeah! You're the nicest being in Cyberspace!
JACKIE: Yup, that's me. Heh.
HAROLD: What are you doing here?
JACKIE: I'll tell you later. But I was wondering if maybe I could have some of your rock candy? Please?
HAROLD: Take it all! We're gonna do more trick or treating.
BUZZ: Come on, Harold! We're ready!
HAROLD: Bye nice girl! Happy Halloween!
INEZ: Okay! Let's count out thirty-five pieces of rock candy.
DIGIT: We need some privacy!
HACKER: Did you just hear something?
ERICA: Only my heart beating, Hacky.
HACKER: You! Check out the castle!
MATT: Thirty-three...thirty-four...thirty-five pieces of rock candy!
DIGIT: Okay, but how do we divide it up so each gargoyle gets the same amount?
JACKIE: Rounds! We can do rounds!
DIGIT: Wu-oh! We got company!
INEZ: I bet we can figure this out faster by using numbers instead of rounds of candy.
MATT: Let's try it. There are seven gargoyles - so each round would be seven candies. Then we just add sevens and see how many sevens it takes to get to thirty-five! And hurry!
INEZ: Seven plus seven is fourteen...plus seven is twenty-one, plus seven is twenty-eight... plus seven is thirty-five!
JACKIE: So how many sevens in thirty-five?
DIGIT: Way to go, Wolfie! Five candies for each gargoyle! Hold it, goyles! Rock candy for all. Chow down!
HACKER: Ah-ha! Tried to escape, did you?
ERICA: What's going on, Hacky?
HACKER: Just a momentary interruption, my dear. Return them to the dungeon! Didn't you hear me?! Lock 'em up!
INEZ: They obey our commands now, Hacker.
HACKER: Oh, please! Do you really expect me to believe that?!
JACKIE: Okay, Hacker, you asked for it. Gargoyles, remove Hacker from the Mayor's castle...now!
HACKER: Ah! Let me down, you grotesque gargoyles!
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
