In this video segment from Cyberchase, celebrity twin sisters are arguing over whose square is bigger on the Gollywood Walk of Fame. When they each measured a side of their individual squares, they got different lengths. The CyberSquad helps them resolve their dispute.
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: What are some measuring tools you might use to measure the length of a piece of wood? How would you decide which tool to use? How do you line up the object with the measuring tool? Does it matter what number you start on?
Focus: As you watch, notice how the twins disagree on the length of the sides of the squares. Why do you think they got different measurements? Why does Matt mention zero?
Follow Up: When you begin to measure an object, what number on the measuring tool should you line up with the edge of the object? If there were no numbers on the measuring tool, would you still be able to figure out the length of an object?
GIRL: Hey! How you doin’?
HARRY: Not so great.
GIRL: What’s wrong?
HARRY: My motor’s not working so well.
GIRL: My motor needs work, too.
HARRY: I hope we get better soon.
GIRL: Are you a kid or a grownup?
HARRY: Can’t you tell?
GIRL: Well, you seem kind of big to be seeing a pediatrician.
DR. LARRY: How long have you been sneezing?
HARRY: About a week. I think i have the flu.
DR. LARRY: Have you had any fevers?
HARRY: No.
DR. LARRY: Any headache?
HARRY: No.
DR. LARRY: I think you might have an allergy.
HARRY: Really?
DR. LARRY: Do you have any pets at home?
HARRY: No.
DR. LARRY: You might be allergic to pollen…or dust…or maybe something else.
HARRY: How can I find out?
DR. LARRY: For the rest of today, I'd like you to keep a record of your sneezes...the location and the number of times you sneeze in a minute.
HARRY: Okay.
DR. LARRY: The data will help us figure out how you can avoid allergy attacks. Don’t forget to come back with that data.
CASHIER: Bless you.
HARRY: Thanks. Hey Inga, I--
INGA: How are you?
HARRY: I was just in the, in the-- neighbor-- I gotta go…
DR. LARRY: You look like you’re doing a lot better, Harry.
HARRY: I’m not sneezing anymore. I don’t get it.
DR. LARRY: Let’s take a look at the data. You did most of your sneezing at Inga’s house. Does she have any pets?
HARRY: Yeah. Daisy Mae. A cat. I took care of her last week!
DR. LARRY: You probably are allergic to cats. I predict if you visit the vet’s office down the block, you’ll do a lot of sneezing there.
VET: Can I help you?
HARRY: Your prediction came true. But if I’m allergic to cats, why did i sneeze when i wasn’t near a cat?
DR. LARRY: You were wearing different clothes earlier today. They must have cat fur on them.
HARRY: Of course! Daisy Mae fell asleep on the jacket I was wearing. So, I’m allergic to cats. What’s the treatment?
DR. LARRY: Clean your jacket, clean your apartment, and no more cat sitting.
HARRY: Thanks, Dr. Larry. Can I have my sticker?
