In this video segment from Cyberchase, the CyberSquad needs help from the Three Fates. In order to keep these three ladies happy they need to figure out how to divide a wreath into three equal pieces, one piece for each of the Fates. The CyberSquad realizes they can use thread and scissors to help them divide up the wreath evenly.

Teaching Tips

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: Have you ever had to cut something up into equal parts to share it fairly with friends? How did you make sure the parts were equal? We call pieces like these, pieces that are equal parts of a larger whole, fractions. Do you know the names of any fractions?

Focus: As you watch this segment, notice how many parts the laurel wreath is cut into. Matt names the parts. What does he call them? Are they fractions? How do you know? How does the CyberSquad make sure that the parts are equal?

Follow Up: When the CyberSquad split the laurel wreath, how were they able to cut it into equal pieces? If you had to cut a piece of rope into four equal pieces, how would you do it? What would you call those pieces (as fractions)?

Transcript

INEZ: Where are we going to get a gift?

JACKIE: Maybe there’s a mythological mall.

CLOTHO: Look, girls. Isn’t this wreath simply magnificent?

LACHESIS: Oh, yes! I do love laurel.

ATROPOS: Me, too. I want it!

CLOTHO/LACHESIS/ATROPOS: (pulling, fighting walla...”Mine!”/ ”I want it!”/”My turn!”/ ”Gimme!”/ ”Get your filthy hands of it!”...)

INEZ: Stop! Lives are at stake here!

CLOTHO/LACHESIS/ATROPOS: Ugh!?

MATT: Time out! Why don’t we just split the wreath into three pieces? One share for each of you.

JACKIE: Ma-att! If you cut it - it won’t be a wreath anymore.

MATT: So? They can wear the pieces as pins or something.

LACHESIS: Sounds like a plan to me.

CLOTHO: As long as her piece isn’t bigger than mine.

MATT: No problem. We just - divide - the - wreath into three - equal pieces. Except I can’t fold it - it’s too stiff!

JACKIE: I have an idea! (to the Fates) You have any extra thread?

CLOTHO: Oh, I love when I do that! She gives Jackie the thread.

JACKIE: It’s a lot easier to fold thread into equal pieces than it is a wreath.

JACKIE: There! Can we borrow your scissors?

ATROPOS: Sorry, I only do life threads.

DIGIT: I got it covered!

JACKIE: Great! Now I can divide the wreath into thirds.

MATT: Beak it, Didge! One third, two thirds, and three thirds!

DIGIT: Three equal pieces!
