(bell rings) (children cheering) - [Narrator] Get ready for a very special super-duper math class.

We're going on a field trip where learning math is tons of fun.

Our destination is the Math Park.

(crowd cheering) (children laughing) - Howdy chipmunks.

Welcome to Math Park.

I'm park ranger A. Rith Metic.

But you can call me Ranger Rith.

Math Park is a place where good times can be counted on along with fingers and toes.

You know, we've seen fractions in so many different ways.

- So we've seen circle models.

What fraction of this model is red?

One fourth, correct.

- The square model.

What fraction is shaded in red?

Four fourths, or you could say one whole, but I don't plan to fall into any more holes.

- Yeah bro.

It wasn't easy getting you out of that hole yesterday.

Now here's the rectangular model.

What fraction of this model is shaded red?

Five sixth.

- And we've seen the ever popular bar model.

What fraction is shaded red?

Two fifths.

Good, muy bien.

- But take a look at this.

It's a group of stars and the stars are different colors.

Did you know this is another way to show fractions?

It is.

First of all, let's find out what our denominator is.

How do we do that?

Count the stars.

How many stars are there?

Six.

Now, how many stars are red?

There's just one.

So if I wanna express this as a fraction, I would say one sixth of the stars are red because one out of six is red.

How many stars are yellow?

That's right, two.

Now express it as a fraction.

Two sixth because two out of the six stars are yellow.

What fraction of the stars are green?

Three sixth of the stars are green.

Do you know what we call this?

Fractions of a set, because the group of stars is a set and we express the colors as fractions of a set.

Good job.

You deserve a pat on the back yeah.

(upbeat music) - [Narrator] Fractions.

Fractions of a set yeah.

All right, dessert time.

We have four dessert cups.

One for me, one for Aunt Joan, one for Uncle Judd and one for Skipper.

I wonder what's going in those dessert cups.

Yeah, looks like ice cream.

There's one, one fourth of the dessert cups has ice cream.

Two fourths of the dessert cups have ice cream.

Three fourths of the dessert cups have ice cream.

Four fourths of the dessert cups have ice cream.

Four fours, that means the whole group of dessert cups have ice cream.

Hey, may I have some whipped cream on mine?

(sound of putting whipped cream) One fourth of the dessert cups have whipped cream.

Hey Aunt Joan, would you like whipped cream on your dessert?

- [Aunt Joan] Yes, darling.

(sound of putting whipped cream) - [Narrator] Two fourths of the dessert cups have whipped cream.

Hey, I just noticed something.

Not only the two fourths of the dessert cups have whipped cream, but also one half of the dessert cups have whipped cream.

Hey, Uncle Judd, do you want a whipped cream on your dessert?

- [Uncle Judd] But of course I do.

(sound of putting whipped cream) - [Narrator] Three fourths of the dessert cups have whipped cream.

Skipper, would you like whipped cream?

- [Skipper] Thanks, I sure would.

(sound of putting whipped cream) - [Narrator] There, four fourths of the dessert cups have whipped cream.

That means the whole group of desserts have whipped cream.

What's that?

You'd like some whipped cream too.

Okay.

(sound of putting whipped cream) (upbeat music) - [Narrator] It's time to play Fraction Match.

Today's contestants are Ivana and Janet.

(gong sounds) Here we go, ladies.

Round one, let's choose our fraction of a set pictures.

(beeping sound) All set, there are the fraction of a set pictures.

Now let's see what fraction the fraction generator is going to show.

Three fourths.

So whose fraction of a set picture shows three fourth shaded red?

It's Janet, because three out of the four triangles are shaded red.

Round two.

(beeping sound) Let's get those fraction of a set pictures.

There we go.

Now let's look at the fraction generator and see what fraction it's going to stop on.

Four fifths.

Now whose fraction of a set picture has four fifth shaded red?

Ivana, because four out of the five stars are shaded red.

Congratulations.

(gong sounds) Round three.

Okay, ladies, here we go.

Let's get those fraction of a set pictures there.

There they are, okay.

Now let's take a look at the fraction generator and see what fraction it's going to stop on.

Five sixths.

Whose fraction of a set picture has five sixth shaded red?

It's Ivana again, because five six of the squares are shaded red.

All right, congratulations Ivana.

You win today's game.

- It's great to be up here with a bird's eye view of the countryside.

Now take a look at that train down there.

There are six cars down there, including the engine.

What fraction of the train is blue?

That's right, it's three sixth, because three of the six train cars are blue.

What, do you see another fraction?

Yes, one half, because half the train is blue and half is yellow.

Hey, look down there.

I think I see somebody who's about to do a karate chop.

(gong sounds) - Sevenths - Howdy green horns.

I'm Math Dillon.

We're gonna have a little quick draw contest to see who's faster at mathematics.

Me or you.

Here's how it's gonna work.

In just a moment, you're gonna see a fraction picture above my head with part of the fraction shaded in red.

Now here's what you gotta do.

You're gonna write that fraction using numbers and see if you can do it faster than I can.

Are you ready?

Get set.

Go.

(laughs) Done.

Did you get five ninths?

'Cause five ninths of the picture was shaded in red.

If you got it, you're smarter than a dickens.

If you got that, then you're quicker than a greased pig in a waffle house.

But I'm gonna get you next time.

(laughs) (Bugle Call plays) (crashing sound) - Did you hear that?

That means Math Park is closing for today.

Until Math Park reopens, I salute you math chipmunks.

(children cheering) - How can I help you today?

- I'm in desperate need of one half.

I used to have one half, but then I accidentally dropped it and it fractioned all over the floor.

- Oh, not to worry.

Take a look at this.

- What's that?

- Math Park is presented by Lucky Cat Productions.
