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: Fractions describe amounts that are less than one whole. If you had a whole carrot and had to share it equally among three friends, how would you cut it up? What kinds of fractions would you have? What if you didn’t want any of the carrot, while one of your friends really liked carrots and you wanted to give her more? How much might you give her?

Focus: In this video segment, watch how Jackie and Inez go about figuring out how to measure out 2/5 of an Electro-Root. Also, notice how the root grows.

Follow Up: How did Jackie and Inez figure out how much of the root they needed? How much was left? If the Electro-Root did not grow in equal parts, how would you be able to figure out how much 2/5 of the root would be?

Transcript

MELVIN: Let’s see...Got it! The antidote for The Mean Green! Whoooooops!

DIGIT: Nooo...!!! I don't suppose you have another one, do you?

MELVIN: Oh, sorry. Wait! The recipe for making the antidote is on the label! Two-fifths of the Electro-Root... two-eighths of the Healing Stone...and one-third of a box of Hacker's Wig Gel!

DIGIT: Bingo! I can make the antidote myself! Oh, who am I kidding? I need kids. Mel, baby, I need a cyber-portal quick!

MELVIN: Not to worry. This is last century's model. It's a little worn, but--

DIGIT: Hee hee... uh... Let me handle this one! Come on, portal...open! I need kids! A squiggly portal appears and out tumble baby goats with their bells. Not Billy Goat kids! Kid kids!!

INEZ/JACKIE/MATT: Oh!

MATT: What's up, Didge?!... Who's your pal in the moo moo?

DIGIT: ...Uh Melvin, the Magnificent, brother of Merlin, the Temporarily Missing!...But... never mind that...Wicked put a spell on Motherboard... "The Spell of the Mean Green"! It’s making Motherboard turn cyber sites nasty, like Hacker! But I have the recipe for the antidote right here!

INEZ: Hmmm, the ingredients are in fractions.

MATT: We have to collect those ingredients before Motherboard turns all of cyberspace mean and green!

DIGIT: At last check she had only 723 sites to go!

INEZ: Jackie and I will get the Electro-Root!

MATT: The Didge and I will get the Stone!

JACKIE: And we'll meet up at The Grim Wreaker for the Wig Gel.

MELVIN: Uh...w-well, don’t forget to drop by for the Sorcerer’s B-B-Ball next year! Tootle-loo!

INEZ: Uh?

JACKIE: Sure.

MATT: Right.

HACKER: Yeeessss! You did it, Wicked! You did it! The Spell of the Mean Green is working to perfection! Motherboard is doing all my dastardly deeds for me. Ha ha ha ha ha ha!

WICKED: Ooooh, I love it when you’re pleased, Hackie. Screen check!

PIG 1: Would you be so kind, dear brother, as to pass me some more mortar?

PIG 2: By all means, dear brother. Ha ha ha ha!!

PIG 3: Ha he he he!

WICKED: Ha-ha-ha! There goes Happily-Ever-After!

HACKER: Only 694 more sites to turn bad! Once this number drops to zero... Cyberspace will be mine!!! And for helping me out like this - I have a present for you. Hacker pulls out from behind his back, a new pink and green broom. He holds it out for Wicked.

WICKED: A broom??! I make it possible for you to take over Cyberspace - and you give me a broom?!!

HACKER: Not just any broom, my wonderful Wicked. The Bimbus 4000! Now you can fly in style!

WICKED: You want to see style, big boy? Watch this?!

HACKER: YEOW! Buzz - Delete - get me my wig gel! Brush! Mirror! Hello, handsome!

BUZZ: You know, boss, I think Wicked was upset.

DELETE: Yeah, she was disappointed all she got was a broom.

HACKER: How could anyone be disappointed in The Hacker? I'm undisappointable! I know, I'll make a video about myself. Yes, that's it – I'll show her just how marvelous I really am!

INEZ: The last time we saw the Electro-Root it was sitting on a gorilla's head.

JACKIE: Omigosh! This is so perfect - the Electro-Root!

INEZ: If this is so perfect - you get it!

JACKIE: Shhh!

INEZ: Wooo Aghh!

JACKIE: Got it! How much of this root do we need?

INEZ: Two fifths of the whole thing.

JACKIE: So we only need part of it...but just how much is two fifths? I mean, I can see if we broke it right here – we’d get two equal halves. But how do you get two fifths?

INEZ: Well...I suppose we could break the whole root into 5 equal pieces.

JACKIE: Then one piece would be one fifth...

INEZ: ...and two pieces of the whole root is just what we need! Two fifths!

JACKIE: Check it out! One, two, three, four, five! The root actually grows in five equal parts! Here’s one-fifth...two fifths!

APES: OOK AWK! ape walla

INEZ: I guess nap time is over.

BIGGEST APE: Oooh oooh ooh ooh ahh ahh!...

JACKIE: Let me explain, Mister Ape, okay? You see...we just need two fifths of the root to help fix Motherboard and you can keep the rest. And, actually, you get more than we do, 'cause three fifths is more than two fifths, see?
