- [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 Riff, Ashley, Charles Barbara, Mike, Janet, Kippin, Bill and Math Dillon.

(cheery music) - Hello chipmunks!

Welcome to Math Park.

I'm park ranger, A. Rith Metic, but you can call me Ranger Riff.

Math Park is the place where flowers stay in bed all day, weeds have a rooting interest, and math is always fun.

We're gonna have a grand time today, so let's get started!

- We're learning about numbers in the thousands place today.

(cheering) - [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 100.

And if you have 10 hundreds, it looks like this.

This is 1,000.

So remember one, 10, 100, 1,000, and we can use these blocks to make numbers.

Watch this.

- Okay, let's stir up this stuff in the frying pan.

Let's see what we're going to get here.

Ooh, this is interesting.

There's 1,000, 100, two tens, and two ones.

What number does that make?

That's a big one.

1,000, one hundred block, two tens, and two ones.

If you said 1,122, very good.

Okay.

Now let's see.

We're getting a nice shower, a nice bath here in the sink.

And I think it's about time to turn the water off, cause they're all clean.

There we go.

All right.

What number does this make?

Let's see.

You have 1,000.

You have two hundreds.

You have two tens and three ones.

What number does that make?

If you said 1,223, great job.

You've got it, that was a tough one.

And we have something baking in the oven here.

It smells like it's done.

Wow.

What number does that make?

If you said 1,136, you did a great job and I think you deserve a treat.

Let's eat!

- [Narrator] Time for another episode of Bill and Barbara's Math Drama.

- Honey, I'm home!

Well, I see it's typical day, what's wrong?

- Something came in the mail.

- Oh no, not a letter from your uncle Moses saying he's coming for a visit?

- No Bill.

It's a bill!

- Oh no, not a, not a bill, bill!

I need to sit down.

- Yes, Bill.

It's a bill, Bill.

It's for the roof repairs.

Take a look at this.

- Dear Bill Buxley, please pay there's 1,000, then 200, then 30, then one.

Hmm.

I've never seen a bill like this before.

- It's such a big ambiguous bill, Bill.

- Barbara, chill.

This might not be so bad.

Maybe it's like one of those tests you used to take in school where we can choose the best answer.

- You mean we get to choose the amount we want to pay?

- Sure.

I think it's so nice of the roofing company to give us such nice choices like this.

- Oh, which amount should we circle?

- They did do a pretty nice job.

$1,000?

We did just win $1,000 in that contest a while back.

- But we were going to use that $1,000 to buy a lifetime supply of popsicles, remember?

- Well then let's circle $1.

What a generous roofing company.

- But wait, look at these little signs.

- I think those are plus signs.

They make me nervous.

- Oh no.

And under each number, there are words.

Look, under 1,000 it says labor, and under 200, it says entertainment tax.

- Entertainment tax?

- Oh yes.

Remember that roofing man was playing an instrument on the roof?

What was it?

- Oh yes.

His fiddle.

That's why there's an entertainment tax.

And under 30 there's shingles, and under one there's nails.

- Wait a minute.

All these plus signs mean that we need to add all of the amounts together to get the total bill.

- You're right.

This bill is in expanded form.

Let's add it to get it in standard form.

- [Narrator] Bill is a very fast adder, but he's afraid he might make a mistake.

So he goes back and adds a little slower.

He writes down 1,000, 200, 30, one, and then he adds the ones column, the tens column, the hundreds column, and the thousands column.

And he gets 1,231.

- Wow.

That adds up to $1,231.

Oh, the price of staying dry.

- Just be thankful we have the money.

- I am.

And I just know that all of our troubles are behind us.

(running water) What's that?

- Oh no.

It's a water pipe in the kitchen.

It's busted, and water's going everywhere.

- Tell me something Bill.

- What's that Barbara.

- Did you pay our water bill?

- (grunts) - Well, that was a dumb thing to do.

- [Narrator] Tune in again for another episode of Bill and Barbara's Math Drama.

- I'm glad that Bill and Barbara took swimming lessons last summer.

They now have a house with a pool.

- 1,523.

What number is in the thousands place?

Can you say it before the number turns blue?

- Hey Sam.

- Hey, what boss?

- If you had $475 in one hand, and $875 in the other hand, what would you have?

- I'd have pretty big hands!

(discordant piano playing) - Greater than, less than?

Man, it can be confusing, dude.

But I figured out a way to keep it straight.

All you got to think of is the mouth of a big fish open towards the biggest number.

Now let's check out what's happening back at the ocean.

There's 341, and next to it is 431.

Which number is larger?

That's right, 431.

So the fish's mouth would be open to eat the 431.

Whoa!

Did you see that?

Everybody out of the water!

I just saw a hungry less than sign!

- That's not funny.

This show needs more dancing.

- [Narrator] Sometimes at Math Park, people get so inspired by the numbers they just start dancing.

So what's the number on the left?

2,867.

And the number on the right?

9,439.

So, what should go between them?

Greater than, or less than?

Less than, because 2,867 is less than 9,439.

And that's pretty easy, you just look in the thousands place.

Two is less than nine.

Okay.

Now what are they going to do?

Oh, look, they're changing places.

Now What should go in between them?

Greater than, because 9,439 is greater than 2,867.

Oh yeah, guys.

Shake it, shake it.

- [Narrator] 9,876.

- [Narrator 2] Yeah.

That's right.

- [Narrator] Well, can you find the value of nine and this number?

- [Narrator 2] Yes.

I can find the value of nine in this number.

You don't think so, watch this.

Okay.

Let's start at the last digit.

Six is in the ones place.

Seven is in the tens place.

Eight is in the hundreds place and nine is in the thousands place.

Nine thousands.

The value of nine is 9,000.

- [Narrator] Correct!

- [Narrator 2] Yabba dabba doo.

- Now it's time for the Math Park mystery number.

See if you can figure it out.

Clue number one, the digit in the thousands place is the same as the number of noses a dog has.

- Clue number two, the digit in the hundreds place is the same as 15 minus 10.

Clue number three, the digit in the tens place is the same as 16 minus 14.

And clue number four, the digit in the ones place is the same as the number of wheels on a tricycle.

Did you solve the mystery?

Today's mystery number was 1,523.

If you got it right, hot diggity.

If you didn't keep trying, you'll get there.

(rooster crowing) Did you hear that?

That means Math Park is closing for today.

Until Math park reopens, I salute you math chipmunks!
