Lesson Plans Using this Resource:
In this video segment from Cyberchase, Hacker and the CyberSquad are racing each other to try to reach the Good Vibration, which is set on top of a tall monument. Two sets of stairs appear and Hacker chooses the one with larger steps. The CyberSquad must use the stairs with smaller steps, so they are afraid they will never catch up to Hacker.
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: Looking at the rate at which something increases can be interesting. If there are two jobs and the first job pays a dollar a day for thirty days, and the other one pays one cent on the first day and then doubles each day for thirty days, which job pays more over the course of 30 days?
Focus: As you watch, look carefully at the two sets of steps. Digit says, “Our steps are so much smaller, we’ll never catch up to him.” Look for a possible pattern in the way both set of steps increase, and decide whether or not you agree with Digit.
Follow Up: Do you believe that if the stairs continue to appear in the same way they are now, that Hacker will reach the top first? Why or why not? Is it possible to write about what you see using numbers? Is there a pattern?
HACKER: At last...I found the Good Vibration! And now to destroy it! How do I get up there?
RED WARRIOR: There is but one way: the Staircase of La.
HACKER: Where is it? I don’t see any staircase!
KIDS: Whoo hoo! Ahhh!
HACKER: Those miserable mites escaped! How could they?
HACKER: Show me that staircase now! Or say good bye to Pi!
RED WARRIOR: I...I don’t understand. It’s not working.
HACKER: Ah, I’ll do it!
RED WARRIOR: What have you done?!
HACKER: Two staircases??
RED WARRIOR: It is the way of the La...sort of.
HACKER: I’ll ride the big ones! That’s the way of The Hacker!
INEZ: It’s Hacker!
MATT: And he’s going after the Good Vibration!
JACKIE: We’ve got to stop him!
HACKER: You’re too late, kiddies!
DIGIT: Pull the plug, Red! Stop the stairs!
RED WARRIOR: Hacker has damaged the mechanism. The progress of the stairs cannot be halted.
ANGLE ON: Inez runs to the blue staircase.
INEZ: We’ll ride this other staircase!
JACKIE: No fair! Hacker’s steps are way bigger!
MATT: We don’t have a choice, Jax! C’mon!
HACKER: It won’t be long before Shangri La is a pit of ugliness and despair! Bla! Toodle loo!
DIGIT: Our steps are so much smaller; we’ll never catch up to him!
