In this video segment from Cyberchase, Digit competes against Hacker in a cooking contest. Digit is making a CyberSouffle that takes exactly 12 minutes to cook. Using a digital clock, he must figure out exactly when his CyberSouffle will be done. He runs into a bit of a problem when his addition results in a time of 9:62, but he soon realizes how to adjust his answer.
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: Are there 100 minutes in an hour? If not, how many minutes are there in an hour? If it is 7:55 a.m. and you run for five minutes, what time will it be when you are done? What time would it be if you started at 7:55 a.m. and ran for six minutes? How did you figure this out?
Focus: In this video segment, Digit tries to calculate when his CyberSouffle will be done. What problem does he run into after doing his calculation? What does Matt do to help?
Follow Up: What time will Digit’s CyberSouffle be done? Even though the watch broke, Matt and Digit were able to figure out what time the soufflé will be done. How did they do it?
MATT: Nice try, Hacker...but no Chef's Hat!
DIGIT: Yeah, The Didge is back and ready to make his famous CyberSouffle!
HACKER: We'll see whose souffle wins today! Hello? Souffles-to-Go? Hello... Hello?!
BUZZ: What is it, boss?
HACKER: Ugh! My phone doesn't work! So much for the 'Call Anywhere From Anywhere Plan!' I'll have to make my own souffle!
DIGIT: Sugar...it needs sugar! Now comes the hard part - cooking it. The souffle has to cook for exactly 12 minutes - not a moment earlier or later! And we have to be very, very quiet.
DIGIT: Once the souffle is in the oven, any loud noise will flatten it!
MATT: Okay, we need to know what time it'll be when twelve minutes have gone by.
DIGIT: No biggie. What time does your watch say right now? Right now it's...9:50. So I'll just add 12 minutes to 9:50 and that gives me...9:62!
MATT: There's no such time as 9:62!
DIGIT: There's not?
MATT: No, there's not.
DIGIT: YOIKES! Now what do we do?! I was gonna count forward on the clock.
MATT: Don't panic, okay? The clock face may be gone - but we still have the minutes marked on this strip.
DIGIT: Oh, yeah...I see. It sorta looks like a ruler - but it measures time!
MATT: Right! We can use these marks to show the minutes in an hour. Here's 9:30, 10:00 and 10:30. We put the souffle in at 9:50, which is right here...And count forward, five...ten minutes... Now we're at 10 o'clock. Add two more minutes...and that takes us to...10:02!
DIGIT: That's why my addition was weird! These are telling time numbers - not just plain old numbers!
MATT: Exactly! Nine-sixty-two is really a whole hour after nine - plus two minutes. The take out time is 10:02!
DIGIT: All we have to do is wait and watch the clock till its 10:02. Except...THE CLOCK IS BUSTED!
MATT: Sh-shush! But this one isn't!
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.
