(school bell ringing) (audience cheering) (upbeat intro music playing) - [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.
With our friends Ranger Rith, Ashley, Charles, Barbara, Mike, Janet, Kiffin, Bill and Math Dillon.
(audience cheering) (upbeat music playing) - Hello, chipmunks.
Welcome to Math Park.
I'm Park Ranger A. Rith Metic, but you can call me "Ranger Rith".
Math Park is the place where lakes will ponder, trees are never stumped, and math is always fun.
We're going to have a grand time today, so let's get started.
- [Narrator] This is a one.
If you have 10 "ones", it looks like this.
This is a 10.
If you have 10 "tens", it looks like this.
This is a hundred.
And if you have 10 "hundreds", it looks like this.
This is a thousand.
So remember: one, ten, hundred, thousand.
And we can use these blocks to make numbers.
Watch this.
Let's see what numbers we have being fried up in the frying pan here, we have... Oh, those look delicious.
We have two "hundreds" and one 10.
And what number does that make?
If you said 210, you're correct!
And we have some base 10 blocks in the sink here, getting all cleaned up.
Looks like they're just about ready and let's get a closer look and see what number we made.
Can you tell me?
We have two "hundreds" and two "ones".
If you said 200 too, you're absolutely right!
Okay, we got something coming out of the oven here, looks like it's delicious.
What number does this make?
You tell me!
130 is right!
100 and 3 "tens", 130, good job.
Let's eat!
- You know what?
It's time for my favorite TV show: Bill and Barbara's Math Drama.
(soap opera dramatic music playing) - [Narrator] "Bill and Barbara's Math Drama".
- Barbara, I'm home!
Hey angel face, what's wrong?
- Come over here.
Sit down, Bill.
This came in the mail today.
(dramatic music plays) - Dear Bill and Barbara Buxley.
You have been selected to win $1,000 dollars in cash, if you can identify this simple number on the attached page.
(page turning) Hmm.
- Hmm is right!
Our chance to win $1,000 dollars and we have to solve one impossible puzzle!
Why is life so cruel?
- I don't know, I don't know.
But we must try our very best.
It's our only chance.
- You're right.
- Wait a minute!
- What is it?
This drawing looks like something I've seen before!
- You're right!
Aunt Josephine gave me something like this for Thanksgiving.
See?
- Thanksgiving, huh?
She must've been thankful to get rid of them.
What are they?
- Base 10 blocks.
This is 1.
This is 10.
And this is 100.
I saw it on TV just a few minutes ago.
- Thank goodness you were tuned into educational television.
So we have some "ones", "tens" and "hundreds" here.
How is that going to help us win the thousand dollars?
- Look, Bill, if you'd only look!
There are two "hundreds" here, and seven "ones" here.
- Yes, but Barbara, there's something missing here.
There are no "tens".
What could have happened to them?
Do you think someone stole them?
- It could be!
There are no "tens" drawn here, only these two "hundreds" and seven "ones"!
- Then I think I have the solution to this puzzle.
The answer we need to write down in standard form, it's written like this.
- That's 27, do you think that's right?
- How could you doubt me in a time like this?
- Because it looks like there are more than 27 cubes.
I mean, we already know that there are 200 right here.
- 200, and 7 more.
That would make...
Uh... - 207!
- That must be right.
Yes, it makes perfect sense.
The two is in the "hundreds" place, the zero is in the "tens" place, because there are no "tens".
And the seven is in the "ones" place.
207 is correct!
- Yes, yes...
Yes!
- Let me se that.
It says here we need to call before five o'clock and tell them the correct answer.
- Call them now, Bill, call them now!
- Hello, counting central?
This is Bill Buxley.
The correct answer is 207.
What?
We won?
Thanks!
We won, we won!
- $1,000 dollars!
It's all ours!
- How should we spend it?
(rain thunder roaring) (rain falling) - How about a new roof?
- [Narrator] Tune in again, for another episode of "Bill and Barbara's Math Drama".
- Wow, it's raining ducks and chickens!
I'm so tired of this foul weather.
(ducks quacking) (relaxing music plays) 415.
What number is in the "ones" place?
Can you say it before the number turns blue?
(clock ticking) - [Both] Let's see what's happening at the beach!
- We've got some interesting numbers, all going for a swim and they all have a seven in them.
There's the number 72!
What's the value of the seven in 72?
The value is 70, because the "7" is in the "tens" place.
Here's the next number: It's 17!
What's the value of the seven in 17?
The value is "7", because the seven is in the "ones" place.
It's seven ones.
And here comes the last number.
It's 713!
What's the value of the seven in 713?
The value is 700, because the seven is in the "hundreds" place.
That was a good math lesson and a good swim lesson!
Let's towel off and head back to the playground!
- [interviewee] 239.
Hmm, okay.
- [Interviewer] Well, can you tell me what's the value of two in this number?
- [interviewee] Well, let's see.
The nine is in the "ones" place.
The three is in the "tens" place and the two is in the "hundreds" place.
Two "hundreds"!
So the value of the two is 200!
- [Interviewer] Perfecto!
- [interviewee] You sound surprised.
(drum sting/comedy fill) - [Narrator] Can you tell me what this number is?
If you said 315, you're right!
That's 315 in standard form.
I wonder if he can show it to us in expanded form?
There it is!
300 + 10 + 5.
That's 315 in expanded form.
- Why didn't they have slides like that when I was a kid?
(western music playing) - Howdy, greenhorns!
I'm Math Dillon.
And we're going to have a little quick draw contest today, to see who's fastest at writing in expanded form.
And I'm going to tell you how we're going to do it.
I'm going to give you a number in standard form, and then we're going to grab a piece of paper and writing utensil, and when I say draw, we're going to see who can write it out in expanded form fastest.
So here's your standard number: 777.
Hey, hey, no, no, don't start yet, you wait until I say draw!
I saw you in the back row.
All right.
Get ready.
Get set, Draw!
(laughing) (evil laughing) Done!
If you got 700 + 70 + 7, then you got it correct!
Well, that makes you smarter than a hen in a fox house!
Or a Fox in the hen house!
Maybe you're smarter than a house!
But I'm going to get you next time!
(evil laughing) - Hey Sam, why was 6 afraid of 7?
I don't know, boss.
Why was 6 afraid of 7?
Because "7, 8, 9".
(sighing) (plays out of tune piano chords) - That's not funny.
You need a real challenge... Like this: - And now it's time for the Math Park Mystery Number.
See if you can figure it out.
Clue number one: The digit in the "ones" place, is the same as the number of eyes a cat has.
Clue number two: The digit in the "tens" place is the same as 500 - 500.
Clue number three: The digit in the "hundreds" place, has the value of 500.
Did you solve the mystery?
Today's mystery number was 502.
If you've got it, hot diggity!
if you didn't keep on trying.
(high pitched laughing) Did you hear that?
That means Math Park is closing for today.
Until Math Park reopens, I salute you, math chipmunks!
