[uplifting music continues] - I'm here today with- - Lily.

- Lily, thank you so much for joining me.

Okay, so we are working on three-digit place value.

And the activity we're gonna do today is called What is the Value of Your Name?

So Lily is going to help me today.

We're gonna find out how much her name is worth.

We already know that names are unique, that they're special, and they're valuable because they make us special.

So what we're gonna use are base-10 blocks and some centimeter cubes to build her name.

So Lily's gonna start off by building her first name, Lily.

And then she's gonna build her middle name.

- Because my first name is very short.

- Yes, so go ahead, Lily, and start building.

These blocks here are our ten-sticks.

So there's 10 cubes here.

This makes a 10.

And then the single cubes are worth how much?

- One.

- One, so she's gonna go ahead and build her name.

- And these.

- Yeah.

- This one is the hundreds.

- Our hundreds, right?

Which is if we had 10, 10 ten-sticks, we would have a hundred.

- But it doesn't mean that we have 100 letters in our name.

- It does not, it just might mean that we have 100 cubes.

But we're gonna find out when she finished building her name.

[gentle purposeful music] So I noticed that for the second L in your name, you're just using 1 ten-stick, right?

- Yeah.

- 'Cause that's the lowercase letter.

Okay, that works.

[gentle purposeful music continues] - [Lily] And every single name has a special meaning.

- It does, right?

Every name has a story.

All right, great.

So let's see.

I'm gonna just move this a little closer so we could see.

So Lily, can you say your full name again?

- Lily Hin He.

- Very good, so Lily, you used a combination of ten-sticks and some of our one-cubes to build your name.

So now, what we're gonna do is we're going to find out the value, right?

Wait, this is a math, so we're gonna actually find out what the value of your name is.

And how we're gonna do it at is we're going to use our hundred, tens, and ones place value chart to do that.

So Lily, you can go ahead and move that board out the way.

Thank you.

And what we're gonna do now, Lily, is you can put this down in front of you, you can go ahead and write your name here.

It says, "My name is"...

So you can write your first and middle name there.

And then we're going to figure out how many hundreds, how many tens, and how many ones we have to figure out the actual value of our name.

[gentle purposeful music] So now, Lily, what I would like for you to do is I would like for you to take all of the one-cubes from your name and place them in our ones place on the place value charts.

[gentle purposeful music continues] Now, we're gonna take all of our ten-sticks and place them in what column?

- The 10 place.

- In the tens place, let's do that.

So now, Lily, let me ask you a question.

The way we have our cubes in the ones place and the tens place, is it easy to count this way?

- No.

- Not really, right?

We need to organize it.

So let's organize first by counting how many ones we have.

Now, Lily, when we get to, how many ones do we need now to make a 10?

- 10.

- So 10 ones.

So every time we get to 10, we're gonna switch out her 10 cubes for 1 ten-stick.

- We exchange it.

- You were gonna exchange it, okay?

- One, two, three, four, five, six, seven, eight, nine, 10.

Here, there's 10.

- Great, so you can put that right here.

And I'm gonna give her a ten-stick.

All right, which she's automatically put right into the tens place, right?

Because it's no longer a one.

Can we keep counting those ones and see if we need more?

- Definitely.

[Tahese chuckling] One, two.

- Great, we have another 10.

So, so far, we have done two groups of 10, which is 20, right?

We just added 20 more to our tens, wow.

[gentle purposeful music] - Yeah, that's 10.

- Great, here's another ten-stick, ooh.

[gentle purposeful music continues] Okay, another group of tens.

So now we have four tens.

Four tens means that we have 40.

Okay, so how many ones do we have left now?

Do we have another group of 10?

- No!

- No, how many do we have there?

[gentle purposeful music continues] - [Lily] Seven.

- Seven, so we can leave that there, right, in our space?

Do you wanna write down the number that we have so far so we don't forget?

You can put a seven there, okay?

So, so far, we have seven in our ones spot.

Okay, now, we're gonna count our tens, okay?

Now, Lily, how many tens do we need to have to make 100?

- 10.

- So if we have 10 ten-sticks, then we're going to replace it with our hundreds, right?

All right, Lily, go ahead.

Let's start counting our ten-sticks.

How many ten-sticks we have?

- One, two, three.

[puzzling music] Nine, 10.

[sticks clacking] - Wow, so 10 tens equals... - A hundred.

- 100, so we're gonna go ahead and exchange these for the yellow.

And she's gonna place, where are you gonna place it on your map?

- [Lily] The hundred place.

- [Tahese] Hundred place.

- [Lily] It doesn't even fit.

- Okay, and did we have any more?

We don't have another set of 10 tens, do we?

- No.

- How many tens do we have now?

- Four.

- Four, so what is four tens equal to?

- 40.

- 40, great, and then we have one 100, right?

So let's write on our chart, our digits, okay?

So what number would we write above our hundreds here?

What number would go here?

- [Lily] One.

- [Tahese] One, okay.

And then what would we write above our tens?

- [Lily] Four.

- [Tahese] Four, because we said that four represents 40.

And then over our ones, I think we already wrote the number, but let's write it again.

We're gonna write the number... - [Lily] Seven.

- Seven, so Lily, this is the number that Lily has gotten for her name, okay?

How would we read this number?

We have three digits, and we know that this is the hundreds place, the tens place, and the ones place.

How would we read this number?

- 147.

- 147.

So Lily, we're gonna finish filling in our sentence.

It says, "My name is Lily."

Can you say your middle name for me again?

- Hin He.

- Hin He, I have blank, 100.

So how many one hundreds do you have?

One.

One 100.

- One.

- [Tahese] How many tens?

- [Lily] Four.

- [Tahese] Four tens, and how many ones?

- [Lily] Seven.

- Seven ones in her name.

So the value of your name is... - [Lily] 147.

- Okay, and we would say 147.

Now, we could also, this is what the number looks like, right?

We can also write it in words.

So if we were to write it in words, we would say one hundred forty seven.

That's how.

That's the same as the number 147.

And basically, like Lily told us, it means we have one group of a hundred, right, four groups of 10, which equals 40, and seven ones left over.

I hope that you guys enjoyed learning all about three-digit place value.

I hope that you enjoyed our activity of finding out the value of your name.

You can do this at home at any point, just for fun, right?

But it also helps with math.

So thank you again for joining us, and we'll see you next time.

Bye.

- Bye.
