In this video segment from Cyberchase, the CyberSquad is trying to help the Fairy Tale people save their king. To do this the CyberSquad must count out 777 golden eggs. They don’t have much time and have to come up with a quick and efficient way get an accurate count without counting them one-by-one. They realize if they group the eggs in groups of ten, they will be about to count the eggs more quickly.

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: Sometimes people save pennies in jars or other containers. Once the jar gets filled they usually empty it to find out how much money they have saved up. How would you recommend someone go about counting and organizing a large number of pennies?

Focus: In this video segment, you will watch the CyberSquad as they count and organize a large amount of golden eggs. How does the squad use grouping to help them? Note the size of the groups they create.

Follow Up: What sorts of groups did the CyberSquad organize the eggs into? As they organized the golden eggs into groups, Jackie drew lines on the ground and asked the giant to place certain groups of eggs in certain areas on the ground. Why did she do that? How could it help? If you look at the stacks of eggs before the giant begins to move them, can you compute the total number of golden eggs?

Transcript

JACKIE: We can't let this happen. It's not fair. Nobody should have to live miserably ever after. Nobody!

DIGIT: Not even Hacker?

JACKIE: Okay, maybe Hacker. But nobody else!

INEZ: There's only one solution to this dilemma. We'll help you count!

FT FOLK: Hurrah!!!

MATT: Not so fast! How are we going count 777 eggs in - what did the pig say? A bunch of minutes.

JACKIE: What we need is a plan. Make room, I gotta pace.

INEZ: You pace - we'll start counting.

MATT: One...two...three...four...

DIGIT: At this rate, we should be done... uh... a week from Tuesday!

JACKIE: Oof! What's this?

JACK: I use 'em to carry golden eggs. I have a whole stack over there.

JACKIE: Perfect! We can use these to group the eggs.

INEZ: Excellent, Jax. Matt, toss me some eggs. 8-9...and 10! Cool! Each box holds a group of 10 eggs.

JACK: So?

JACKIE: Don't you see? If we fill the boxes with eggs - we can count by ten instead of one by one. It'll be way faster.

MATT: Okay, fairy tale people, we've got some serious grouping to do.

SPIDER: I'll help. They always do that. I just want to be accepted - be a useful member of fairy tale society!

JACKIE: Oh don't cry, Spider. We're not afraid of you.

SPIDER: I only got hit by a little bit of the spell - so I sorta remember how to count.

JACKIE: Just fill this box and you'll have 10 eggs.

INEZ: Group and conquer!

MATT: Is that another one of your quotations?

INEZ: Nope. But it has a nice ring to it, don’t you think?

TOWN CRIER: Hear ye, hear ye! Remember how many sands of time we had before? Well, there’s a lot less now!

JACKIE: Okay, we're making progress. We've grouped all the eggs in boxes that hold 10 eggs - and we've got 9 eggs left over.

MATT: But, Jax, the boxes are all over the place. How are we ever going to get them counted in time?

JACKIE: Hey, I'm working on it, okay!? Make room, I gotta pace!

DIGIT: Pacing going on!

INEZ: Make room!

MATT: Let's stack these up.

JACKIE: A plan...we need another plan. That's it! If we stack up 10 boxes like this – we have a group of 100 eggs!

INEZ: Because ten 10's equals 100!

MATT: Which means fewer groups to count so we can count faster! Start stacking!

JACKIE: Okay, everybody listen up.

FT FOLK: Listening up!

JACKIE: Now, we grouped all the eggs in stacks of 100 - boxes of 10 and singles. It's time to organize them by grouping boxes with boxes and stacks with stacks.

INEZ: I forgot, gold is really heavy.

JACK: Can I help?

INEZ: Heh. Oh, like you're stronger?

JACK: Didn't say I was, but I know who is.

GIANT: Fe-Fi-Fo-Fum! I smell the blood of an Englishman!

DIGIT: Save it for the book, big guy, we need a hand. Now that's a hand! Whoa!

JACKIE: Okay, Mr. Giant, we've got 9 single eggs in this place. Now, we need you to move the 7 boxes of 10 eggs into this place here. And the 7 stacks of 100 eggs into this place.
