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: What sort of features do you typically find on a map? How about on a globe? Have you ever seen vertical and horizontal lines on maps or globes? What are they for?

Focus: In this video segment, the CyberSquad is split into two groups, and they are trying to find each other. They have maps on their Skwak pads, but that is not enough. As you watch, notice what they do to make their maps more useful.

Follow Up: How does a grid on the map help the CyberSquad locate their exact positions? Could you make a map of your classroom with a grid on it? Using the grid, how would you describe the position of your desk?

Transcript

MATT: I hate to say this, but I think we're lost!

JACKIE: A plan, a plan...we need a plan. I've got it!

JACKIE: I'll copy Motherboard's map onto my Skwak Pad and send it to both of yours.

INEZ: Map comin' through! Now what?

MATT: That must be Haystack Mountain! We know where we are again! See? That mountain matches the shape and position of the haystack mountain icon.

JACKIE: Excellent! Meet you at the hill with the flat top. You see it?

INEZ: You mean the hill past Haystack or the one next to the geyser?

MATT: We'll never match up the landmarks this way!

JACKIE: Wait a minute! Inez, do you see the grid on your map?

INEZ: Do you mean these lines that sort of look like graph paper?

JACKIE: Right. What if we mark the vertical lines with letters from left to right?

INEZ: You mean like A...B...C...D...E...F...G...H?

JACKIE: Yes, now mark the horizontal lines with numbers from bottom to top.

INEZ: Okay. 1...2...3...4...5...6...7 ...8.

MATT: I get it! Each landmark is on the grid somewhere. If we're at haystack mountain here on the island, then we're at G4 on the map! Cool!

JACKIE: And if we're at the waterfall, we're at E...3!

MATT: Okay, there's a bridge on the way at D...6. Let's meet there.

JACKIE: Excellent! Let's keep in touch. See you at D6!

INEZ: Bridge at D6. We made it!

MATT: Inez!

INEZ: Yikes! I owe you one, Matt.

JACKIE: We're here!

MATT: Let's jam!
