[upbeat cheerful music] - Hi friends, okay, here we are.

We're getting ready to play our money game.

I have with me here my friend.

- Malena.

- My mathematician friend.

So today, I'm going to write a number value in cents and you are gonna show it to me using our magnetic coin.

So let's just review.

This is 50 cents, which is a half dollar.

These are quarters, which are worth 25 cents.

We have these, which are dimes.

They're worth?

- 10 cents.

- These are?

- $5 cents.

- Five cents.

And these are?

- Pennies that are worth one cents.

- One cents, so 50 cents, 25 cents, 10 cents, five cents, and one cents.

So if I write 55 cents, can you show me what that's gonna look like?

- So I could take this half dollar coin, which is 50, and then plus this nickel, which is this five.

- This would be 50 plus five equals 55 cents.

Is there another way we can do it with different coins?

- So we can take a dime, we could take five dimes.

- [Zoe] Five dimes, which is each dime is 10 cents.

- So the value equals 50 cents.

50 cents plus a nickel which is equal to 55 cents.

- So each dime is worth 10.

So let's count 10, 20, 30, 40, 50, plus five more equals 55 cents.

Wow, is there another way you can show me 55 cents?

- So a quarter equals 25, and another quarter equals 25, so it equals 50.

And then 50 plus a nickel equals 55.

- Fantastic, you are a money expert.

All right, let's try another number.

If I wanted 37 cents, how could I do that?

- So you would take a quarter, and then you could take the nickel, which equals 30, and then 30 plus you could do another five, and then plus two pennies.

- All right, so we have 25 cents plus five cents, 25, plus five, plus five, plus one, plus one.

So that's 25, 30, 35, 36, 37 cents.

So equals 37 cents.

Excellent, let's see.

That was a lot of coins, the one.

Can you show us another way we can make 37 cents?

- Yes, so you could take three dimes which equals 10 cents.

- Three dimes meaning 10 cents each, right?

- Yes.

- So 10, 20, 30, great.

- And then 30 plus one, two, three, four, five, six, seven pennies, which is each one cent equals 37.

- Right, so 10, 20, 30, 31, 32, 33, 34, 35, 36, 37.

Ooh, that's a lot of pennies, fantastic.

What about, let's see if I can make this 74 cents?

- So I could take two quarters and then I would get this to 50.

- [Zoe] 50 cents.

- And then you could add two dimes would get us to 70.

- Because they're 10 each, right?

- And if you take four pennies, which is each one cent, four pennies, they'll get you to 74.

- All right, let's see, 25, 25 is 50.

10 and 10.

So 50, 60, 70, one, two, three, four, fantastic!

Can you show us a different way to make that?

Yes, like chess.

- Maybe you'll be dealing with lots of money when you're older.

[bouncy music] - So I could take seven dimes.

- [Zoe] Seven dimes at 10 each, 10 cents each.

- That'll get us to 70.

And then plus four pennies, which is each one cents.

- Beautiful, so let's count, 10, 20, 30, 40, 50, 60, 70.

Seven dimes, 70 cents.

71, 72, 73, 74, amazing!

One more, and then we'll finish up.

And then you guys can practice this at home.

Let's try 42 cents.

- So if I did two quarters, it would be 50, so we can't do that.

So we could take one quarter equals 25 plus a dime would get us to 35.

And then 35 plus five would get us to 40.

And then 40 plus two pennies, which equals 1 cents equals 42.

I love the way you're explaining your thinking.

So 25, 30, 40, one, two.

Quarter, nickel, dime, and two pennies, fantastic.

One more way to show 42.

- Okay, so you could take four dimes, which equals 10 cents.

And then you have 40, but you can't add a five because it's five bigger than two, so you have to add two pennies.

- That's right, you put a nickel, it would be 45.

And it's 42.

So great, let's count, four dimes, 10, 20, 30, 40, 41, 42.

You're excellent at money.

All right, friends, I hope you play this game at home.

- Bye.

- See you later, bye.
