In this video segment from Cyberchase, the CyberSquad follows a treasure map with riddles to find Ivanka the Invincible’s secret treasure chest. One of the riddles asks the CyberSquad to record how much of a turn they make from one object to another. To do this, they have to record the angle of the turn.

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: If you were standing and facing a house across the street from yours and you were asked to turn to the right and face a house farther up the street, how could you describe or quantify that turn? Sometimes when we describe turns or movements we talk about the turn in terms of angles. Can you think of an example where you’ve heard about angles before?

Focus: In this video segment, the CyberSquad has to work together to figure out how much of a turn they need to make. Notice how they use the word angle. What do you think they mean by it here? Also, notice how they manage to record that angle.

Follow Up: How did the CyberSquad figure out how much of a turn to make? Why did they record the turn and how did they do it? If you were going to record a turn where you faced the window in a room and then turned toward the door, how would you do it? How would you record the angle of that turn?

Transcript

INEZ: Riddle number two: “Nose to shoulder, spy the boulder - that looks like a hen, but remember the turn, for ye will learn, ye will need it again.”

MATT: Man, talk about a hard riddle. Where’s my yo-yo? I gotta think.

INEZ: Okay, let’s take the riddle in pieces. “Nose to shoulder...

MATT: “Spy the boulder that looks like a hen...” I’ve got it! Jax, your nose points in this direction...and your shoulder points in this other direction, right? So maybe at an angle between your nose and shoulder is a boulder that looks like a hen!

JACKIE: Sorry, guys. No boulder...no hen.

MATT: I’ll turn my spyglass between the angle of your nose and the angle of your shoulder.

INEZ: What do you see, Matt?

MATT: I see the Hen Boulder! It’s in that direction! Come on!

INEZ: Wait! There’s more to the riddle!...‘remember the turn, for ye will learn, ye will need it again.’

MATT: Remember the turn? What turn??

JACKIE: Must be this turn. From where we started...to pointing at that hen-shaped boulder.

INEZ: How are we supposed to remember how much of a turn that was?

MATT: Jackie can just keep her arms like that til we get to the boulder.

JACKIE: Are you kidding me!? No way, my arms are already getting tired!

INEZ: I have an idea! But we need some string.

MATT: Oh, no. Not my yo-yo. No way!

JACKIE: This is really embarrassing.

INEZ: We’ve almost got it. Just tell me when I’m lined up with hen boulder.

JACKIE: Go more to the right, a little more... too much, back a little...there!

INEZ: You sure we’re all lined-up?

JACKIE: I’ll double check. Lined up at the cannon! And this one points to hen boulder!

INEZ: Okay! The string shows us how much you turned!

JACKIE: Great, but how are we going to remember it? I can’t walk around with a piece of string on my nose.

MATT: I’ll trace it!

JACKIE: You better not get ink on me!

MATT: Just don’t sneeze, okay? Now that’s what I call an angle!
