In this video segment from Cyberchase, in order to free the CyberSquad from the Vortex, Wicked and Digit must find the Amulet of Amagansett. When they find the Amulet they realize it is missing some of its jewels. They use what they know about numerators and denominators to figure out how many jewels are missing.
Download and ShareHere are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.
What is Frame, Focus and Follow-up?
Frame: When we look at a fraction we see two numbers. For example, ½ has a 1 on top and a 2 on the bottom. What does the 2 on the bottom mean? What does the 1 on the top mean? What do we call the top number of a fraction? What do we call the bottom number of a fraction?
Focus: As you watch this segment, ask yourself these questions: How does Digit figure out how many jewels are missing from the Amulet? How did the 4/7 fraction clue from Grubby help them?
Follow Up: When Digit was figuring out how many jewels were missing from the Amulet, Wicked said if they found three more they could make it "whole." What did she mean by that? What fraction could be used to describe the jewels on the Amulet if all seven jewels were there?
DIGIT: It's the Amulet of Amagansett! I'd recognize it anywhere. Nice, huh?
WICKED: Nice, but there are some jewels missing. See? The Amulet is lopsided. More jewels on this side...than this side. Believe me, I know jewelry, and unfortunately, without the missing parts, this Amulet's only worth a fraction of its real value.
DIGIT: Missing parts? Fraction? Wicked, you're a genius!
WICKED: Again?
DIGIT: I'll let you know in a minute. Here's the fraction we got from Grubby - four-sevenths. We know the bottom number - the denominator tells us this whole has seven parts.
WICKED: But this Amulet only has four.
DIGIT: Now it does - but suppose it once had seven. And the problem is, some are missing.
WICKED: What we have to do is make it whole again! Right?
DIGIT: Right! And this fraction tells the story! The whole Amulet was made up of seven stones - and we've got four of them...which means? There are three missing!
WICKE: I am a genius! I must add that to my resume.
DIGIT: Find those three missing stones to make the Amulet whole again – and we'll find the Universal Vortex Opener - the UVO for short!
