(upbeat music) (school bell ringing) (cheering) - [Host] Get ready for a very special super-duper math class.
We're going on a field trip where learning map is tons of fun.
Our destination is the math park.
(cheerful music) (children laughing) - Howdy Chipmunks, welcome to math park.
I'm park ranger, A. Rith Metic, but you can call me Ranger Rick.
Math park is the place where we separate fact from fraction and we're going to have some more fraction action.
So let's get started.
- Oh, I am so grateful to be working for the Rich Mrs. Epson, but I have a problem.
She asked me to bake this rainbow cake, but I have a problem with the recipe.
It says for the frosting, I need 1/6 strawberry, 1/6 orange, 1/6 lemon, 1/6 Lime, 1/6 Blueberry, and 1/6 Grape, But I do not understand it.
I do don't know what I'm going to do.
I know, I should call the Denominator.
And fortunately I have him on the speed dial.
(phone dialing) (phone ringing) - Denominator here.
- Denominator, I'm a chef and I am trying to frost a rainbow cake and I need your help.
- Cake frosting aye.
I'll be right there (upbeat music) - What took you so long?
- I was stuck behind a flock of pigeons in Poughkeepsie.
- I do not know what that means, but perhaps you can help me with this.
I do not understand this recipe.
I do not understand what these numbers mean.
- Well, these numbers are called fractions.
- Wash your mouth out.
- No, no, no, no, no, no.
Fractions, fractions.
Do you see this number in the bottom?
It's called the denominator.
- But that, its your name?
- Yes it is and a grand name it is, don't you think?
- Meh.
- This number tells you how many equal pieces you should cut the cake into.
- So I should cut the cake into six equal pieces.
- Precisely, allow me.
(laser noise) (speaking in foreign language) - But I still did not understand this numbers on the top of the fractions.
- That's not my department, I'll call my twin brother.
(phone dialing) - Bro, can you come over here right now at these coordinates?
Thank you.
(whooshing noise) - Hi bro, you called?
- I sure did.
- Who are you?
- Hi, I'm the Numerator.
(intense music) - He is faster then you.
- That's what everyone says.
Well, my work is done here.
Bro, I'm going to go home and say hi to mom.
Would you mind taking over for me here?
- Sure thing.
- Very good and the best of luck to you, goodbye.
(whooshing sound) - Enough of the soap opera.
Let's get back to my problem.
I do not understand what's the number at the top of the fraction means.
- Let me explain it this way.
The bottom number is the denominator, that tells you how many pieces there are all together.
You have six pieces of Cake.
- (speaking in foreign language) this is true.
- The top number, the numerator tells you how many out of each piece.
See, it says one out of six should be strawberry.
- So I should put strawberry frosting on one of these six pieces - That's correct.
1/6 of the cake needs to have strawberry frosting.
- And 1/6 should have orange frosting, 1/6 should have lemon frosting, 1/6 should have lime frosting, 1/6 should have blueberry frosting, And 1/6 should have grape frosting.
- That's it.
- But this cake taking so long, I will never get it frosted in time now.
- Let me help you with that.
(laser noise) - 1/6, that means one of the six is strawberry.
(laser noise) 1/6 is Orange.
(laser noise) 1/6 is Lemon.
(laser noise) 1/6 is lime.
(laser noise) 1/6 is blueberry.
(laser noise) And 1/6 is grape.
(speaking foreign language) (whooshing sound) - What's that?
- I think it was Ranger Rick in the math park helicopter.
- No, no, I think it was a flying saucer.
I better go check it out.
(upbeat music) - [Host] What fraction of the bar is shaded red?
If you said 3/5, you are correct.
Now remember the top number is called the numerator.
- Numerator, Yeah.
- And what do we call the bottom number?
The Denominator.
- Denominator, Yeah.
- I have a feeling that we're going to have a close encounter with the outer space aliens in the math park.
You think so?
Stay tuned and find out.
- This is a rectangle.
1/6 of it is shaded.
- This is a square.
What portion of the square is shaded?
1/4.
- Hello, (speaking foreign language), this is a circle.
What fraction is shaded in?
Did you say 2/3?
Good (speaking foreign language) (upbeat music) - 1/5.
- [Host] That's right, once again, it's time to play fraction match.
Today's contestants are Roberto and Katherine.
Okay, let's see who's going to win round one.
Okay, here we go.
Let's get our fraction pictures up there.
Click those clickers, here we go.
All right, let's see.
Where are they going to stop?
All right, there we go.
Now let's look at our fraction generator, and where is it going to stop?
2/3, whose fraction picture has 2/3 shaded red?
It's Katherine, because two out of the three pieces are shaded red.
2/3, congratulations.
Round two.
All right, let's get those fraction pictures up there.
You got those clickers ready?
Okay, click them.
Let's see where they're going to stop.
Right there.
Okay, let's see what the fraction generator is gonna stop on.
3/4, who has 3/4 shaded in red?
Is it Roberto or is it Katherine?
It's Roberto, he has 3/4 shaded in red.
Congratulations, Roberto.
Okay, let's see, who's going to win round three.
This is our last round.
Let's get those fraction pictures up there.
Click it, okay.
Where's it gonna stop?
Right there.
All right, now let's look at our fraction generator.
Let's look at our fraction generator, there we are, and where is it going to stop?
Oh it's speeding up, let's see.
2/8, okay, whose fraction picture has 2/8 shaded in red?
Take a close look.
Is it Roberto or is it Katherine?
It's Katherine two out of the eight parts are shaded red.
Congratulations.
Good game, Katherine and Roberto.
- Now let's say you're really, really hungry, and you're really, really like candy bars.
And your friend says, they'll give you 1/8 of their candy bar or 1/4 of their candy bar.
Which would you take?
1/8 of their candy bar or 1/4 of their candy bar?
While you're thinking about it.
Let's see what the denominators is up to.
(Cheerful music) - You know, it's a funny thing.
Ranger Rick was talking about chocolate bars, because I'm about to enjoy a chocolate bar.
(whooshing sound) - Hold up bro, hold it.
I've been chasing after flying saucers and I can really use some nourishment.
May I have half that chocolate bar?
- Well Of course, here, allow me to cut the candy bar into two equal pieces.
(laser noise) But wait what's this about flying saucers?
- It's true.
I saw three flying saucers flying over math park.
Wait, what's that noise?
(whooshing noise) (upbeat music) - Greetings Earthling.
Oh yes, we must, we want chocolate.
- You weren't kidding.
Aliens chocolate, okay.
1, 2, 3, 4.
Well, I'll cut the chocolate bar into four equal pieces.
(laser noise) - So each person gets 1/4 of the candy bar.
- Wait, I hear something.
More flying saucers.
(whooshing noise) Oh, now there are eight hungry mouths that want some of the chocolate.
I know I'll cut the chocolate bar into eight equal pieces.
I'll cut it into eighths.
(laser noise) (upbeat music) - Good - Oh wow.
- Thanks for the chocolate, bro.
That was really good.
I was so hungry after helping out the chef at Mrs. Epson's place with a rainbow cake.
- Oh Rainbow cake, we love rainbow cake.
To Mrs, Epson's.
(upbeat music) (whooshing noises) - So let me ask you again.
If your friend offered you 1/4 of a candy bar or 1/8 of a candy bar, which would be larger?
1/4 would be larger.
Remember when the denominator cut the candy bar into fourths, then he cut it into eighths.
When he cut the candy bar into more equal pieces, each piece got smaller.
What would it be larger?
1/3 or 1/6?
(ticking sound) 1/3.
And one more.
What would be larger?
1/6 or 1/10?
(ticking noise) 1/6.
(whooshing noise) Did you see that?
You never know what's going to happen here at math park.
That's why I love this job.
- The rainbow cake, where did it go?
- Rainbow cake good.
(whooshing noise) (breaking noise) - Halves.
(screaming noise ) - Did you hear that?
That means math park is closing for today.
Until math park reopens, I salute you math chipmunks.
(cheering) - You know, all this work is making me hot.
I think I'm going to turn on the fan.
- Oh no..no..oh..no - Math park is presented by lucky cat productions.
