- Hey everybody.

We're learning more about place value today.

Math Park, here we come.

(school bell ringing) (children cheer) - [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, Kippen, Bill and Math Dillon.

(upbeat music) - Hello, chipmunks, welcome to Math Park.

I'm Park Ranger A. Rith Metic.

But, you can just call me Ranger Riff.

Math Park is a place where marshes are mellow stouts are intense and math is always fun.

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

- Can we see those magic blocks again?

- Not a bad idea, let's go.

(happy music) - [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.

- Now let's see what's cooking in the kitchen.

- [Man 1] Oh, look at this, we've got some numbers cooking in the kitchen.

What do we have here in the frying pan?

Let's see.

Two hundreds, two tens, three ones.

What number does that make?

(upbeat music) If you said 223, you are correct.

And we have some base 10 blocks in the sink here, getting all clean.

Let's see, what do we have?

Uh, let's get a closeup.

Can we get a little closer?

There we go.

Hm, one hundred and one ten.

What number does that make?

(upbeat music) If you said 110, you're right, good job.

(upbeat music) Now what's coming out of the oven?

Whoa.

Two hundreds, one ten, and five ones.

What number does that make?

(upbeat music) 215.

Two hundreds, one ten, five ones.

215, good job.

- Base 10 blocks help us understand place value.

We have ones, tens and hundreds.

When you look at a number, we have ones, tens and hundreds as well.

- Let's put away those base 10 blocks.

You're having too much fun.

(children moan) - Now that's one lady who knows how to have fun.

Of all the classrooms in all the world, why did she have to walk into mine?

Well, let's see if you can figure this one out.

(upbeat music) - [Narrator] 831.

What number is in the hundreds place?

Can you say it before the number turns blue?

(ticking sound) - Well, children, you did pretty well on that one.

You've earned yourself a little time out on the playground.

(children cheering) No running.

(playful music) - [Man 1] What is this number?

If you said 123, you are correct.

That's 123 in standard form, let's see if she can show it to us in expanded form.

100 + 20 + 3.

Yep, that's 123 and expanded form.

Good job.

- [Narrator] That says 648.

That's the number in written form.

And here it is in standard form.

648.

But look at this.

This is 648 in expanded form.

600 + 40 + 8.

That makes 648.

- And now it's time for everybody's favorite math cowboy, Math Dillon.

(western music) - Howdy green horns.

I'm Math Dillon.

And I'm here to have a quick draw contest with you to see who can draw an expanded form faster.

This is how it works.

I'm gonna give you a number in standard form, and then you're gonna take your paper and pen and see if you can write it in expanded form faster me.

Let's see who's faster, you or me?

Our number is 527.

Now don't draw until I see the word draw, 527.

Get ready.

Get set.

Draw.

(Math laughs) You better hurry.

(Math laughs) Done.

If you got 500 + 20 + 7, then you are correct.

Well, getting that correct makes you finer then a Saskatoon spittoon, but I'm gonna get you next time.

(Math laughs) - [Narrator] And now it's time to play "Build a Number" where we'll find out which of our two players can build the biggest number.

Will it be Janet?

Or Kippen?

Well, let's find out.

Round one.

The first digit is five.

Alright those fives are nicely in place now and the next digit is five again.

Well, let's see where they're going to put them.

Janet is going for the hundreds place and Kippen for the tens place.

Okay, now let's see what our next digit is going to be.

Our next digit is four.

Okay, Janet has putting hers in the ones place and Kippen can only put his in the hundreds place.

So who built the bigger number?

Janet built the bigger number because 554 is greater than 455.

Congratulations, Janet.

And now round two.

Let's see who's going to win this round.

The first digit is six.

Janet's going for the tens and Kippen going for the hundreds.

The next digit is three.

Ooh, let's see where they're gonna put that.

Janet's going for the ones place and so is Kippen, a very wise move.

Okay our next digit is three again.

Ooh, Janet's gonna have to put it in the hundreds and Kippen is going for the tens.

Who won this round?

(audience cheering) Kippen wins this round because 633 is greater than 363.

Congratulations, Kippen.

And now for our third and final round.

The first digit is two.

Okay, pretty easy choice, I would say they're both going for the ones place.

Very wise move.

And our next digit is seven.

Mm, tough choice here.

Kippen goes for the tens and Janet goes for the hundreds.

And our next digit, the last digit is eight, ooh.

So that only leaves Janet with the tens place and Kippen with the hundreds.

So, who built the bigger number?

Kippen, because 872 is greater than 782.

Congratulations, Kippen.

And Janet?

You played a good game too.

- Now it's time for the Math Park Mystery Number.

See if you can figure it out.

Clue number one, the digit in the hundreds place is the same as 3 + 3 + 3.

Clue number two.

The digit in the tens place is the same as 6 - 4.

Clue number three.

The digit in the ones place is greater than seven but less than nine.

Did you solve the mystery?

Today's mystery number was 928.

If you got it, hot diggity, if you didn't, keep trying.

(party trumpet plays) Did you hear that?

That means Math Park is closing for today.

Until Math Park reopens, I salute you math chipmunks.

(children cheer) (upbeat happy music) (upbeat happy music)
