In this video segment from Cyberchase, Buzz, Delete, and Harold are trying to share 18 pieces of candy equally among themselves. Jackie helps them by demonstrating how to divide the candies equally by distributing the candies in rounds.
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 we have an apple and we want to share it among four people, we can just cut it into four equal pieces. But what if we want to share a bag of peanuts among four people? How would you go about doing that? What mathematical operations would you use?
Focus: During this segment, watch how Jackie insures that the sharing of the candy among Buzz, Delete, and Harold is done in a fair way. How does she start off? Notice what she calls her method.
Follow Up: How did Jackie make sure that the sharing of the candy was done in a fair way? Why did Harold’s attempt at sharing the candies fail? Was there any division used in any of the sharing? If yes, describe how it was used. If you had to share 72 pieces of candy among three people, how would you go about doing it?
HAROLD: Great costumes!
BUZZ: Thanks, Harold!
DELETE: Hey, it's us! Buzz and Delete. Oh, no, Buzzy! I just remembered what you told me not to forget but I forgot to remember when we left - Trick or Treat bags.
BUZZ: No bags, no candy...!
HAROLD: No problem! We can divide up my candy. I have plenty.
DELETE: Whoa, that is a lot! How many pieces do we each get?
BUZZ: I'll divide it up. Let's see, there's three of us --
DELETE: No way, Buzzy! I want the same amount as you - and that won't happen the way you divide.
HAROLD: I'll do it! Harold and Buzz and Delete and Buzz and Delete and Delete and Harold and Delete and Delete and Buzz and Delete and Buzz and Delete and Delete and Buzz and Delete and Harold and Delete...
BUZZ: Hey! Delete's got more than me!
HAROLD: And I got only three!
JACKIE: I'm not mean, Didge... am I? How can my best friend write that about me?
DIGIT: You're not mean, Jax! Lighten up. It's Halloween - we're supposed to have fun! Why so glum, guys? You having Halloween troubles too?
HAROLD: We're trying to divide up this candy, so we each get the same amount - but we're not doing a very good job.
JACKIE: Maybe I can help. Let's start by putting all the candy back in the middle. I used to share my Halloween candy with my best friend - back when she was my best friend. We divided it up in rounds. That way, we each got the same. Watch. One for the mummy, one for Angel, one for the other mummy. That's round one.
DIGIT: Looks fair to me!
JACKIE: One more for the mummy, one more for Angel, one more for the other mummy. That's round two. And the mummy...Angel...the other mummy. That's...
BOTS/HARRY/JACKIE: Round three!
DIGIT: And still fair!
BOTS/HARRY/JACKIE: Round four! Round five! Round six!
DIGIT: And none left over!
HAROLD: I got six candies!
BUZZ/DELETE: Me too!/Me too!
DIGIT: Perfecto! Now you each have the same amount.
JACKIE: Yup. Six rounds so you each get six candies. It's totally fair because dividing up in rounds works! Happy Halloween, guys.
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.
