- Hey everybody.

It's that time again.

It's math time and it's game day.

And I'm so excited because I've got a great game that I want to explain so that you can play wherever you may be.

And all you're gonna need for this game is a deck of cards, kind of like these.

And if you don't have a deck of cards, don't worry because you could make your own if you just have some pieces of paper and a pen or a pencil, and you could design your own.

You're just gonna need the numbers one to nine, and you could write those out on little pieces of paper and there's your cards.

So that's what you'll need today.

And we're gonna play a game called "whose number is larger?"

And I'm really excited about this and it's best played if you have a second person.

So maybe you have a friend, a sibling, or a family member who you could play with.

I have a friend here with me, Emma is here and I'm so excited.

Hi Emma.

- Hi.

- And we're gonna play the game, whose number is larger.

All right, so we're gonna show everybody how to do this.

And the way we start out is we're each going to get two cards.

So Emma, I'm gonna give you two cards and I'm gonna get two cards.

And I'm gonna look at these and we're gonna try and make the largest number that we can.

Now, for just so everyone knows, if you get an ACE in this game an ACE we're gonna treat like it's a one, okay.

And so the way we're gonna make our number is the first number we put out there is going to be in the tens place.

All right.

The second number is gonna be in the ones place.

So if I put this out there and I go, Hey, all right, three.

So that would be like 30.

And then one, that'd be 31.

Now, if I flip that around, I would have a one and a three.

So one 10, and then three, that only be 13.

So which one should I make?

Probably 31, right?

So I'm gonna make the 31.

And that's the largest number I can make with my two cards.

So there I have it.

Now, Emma, let's see what your cards are.

She's got a four and a five, five and a four.

So we can make two different numbers.

She could either put them out there and put that five first and say, you know, that's gonna be in my tens place.

And that'll be 54.

Or you could make 45, right.

So, hmm, I wonder which one we should do, 45 or 54?

So we would put them down and we're gonna see who's number is larger.

So if you put yours down, all right, so I'm looking at it.

I see she put down 54, all right.

So here it is.

She's got 54.

Amazing job, 54. and mine was only 31. Who's is larger, 54 or 31?

- 54.

- 54.

All right, Emma, you win.

So guess what?

You get my cards and you can put those in a pile.

She's gonna put them off to the side and we're gonna play again.

So that's how you play, whose number is larger and you're gonna keep going.

So now we start over, she gets two cards, I get two cards and we're gonna see whose number is larger.

All right, this time I have a two and a three.

So I could either make 32 or 23.

Thinking which one's larger?

Well, the largest one I can make is 32.

You've got a seven and a four.

All right, yours is bigger than mine.

So you have 74.

She's holding up, she has 74.

Well, 74 is larger than 32.

You get them again.

Oh my goodness.

All right, so Emma's winning this game.

So we're going to show you a second game.

All right, so we're gonna do something a little bit different.

It's kind of similar to whose number is larger, but this one is called "addition battle."

Okay, so we're gonna play addition battle this time.

So we'll put these off to the side or I'll just put them underneath and I'll say, all right, it starts the same way.

So I'm gonna give you two cards, all right.

I'm gonna take two cards.

And this time we're actually going to add our numbers together.

So we're gonna treat them as two separate numbers.

All right.

And we're just going to add them and see who's makes the largest number, so the largest answer.

Now, remember with addition, the order doesn't matter, nine plus seven is the same as seven plus nine.

So if I add these together, nine and seven, and you can either count them if you have the cards or you can think of an addition strategy to come up with.

Mine, I think is 16, nine plus seven is 16.

All right, let's look at yours.

What do you have Emma?

You've got a five and a four.

All right, she has a five and a four.

So if you were to add those two numbers together, - Eight.

- Eight, okay.

Eight is four and four.

So you're really close.

Now you have a five so one more up from that eight plus one, what would that be?

- Nine.

- Nine, she's got it, nine.

Okay, now let's look at mine.

I had 16, you had nine, whose number was larger?

- Yours.

- Mine was larger.

All right.

So I get it that time, I won one finally, you won all the other ones.

So that's our game.

So we have two games.

Remember we did addition battle where you're adding those two numbers together.

We had, whose number is larger, where you were arranging those with place value, to who can make the largest number.

All right.

So keep learning, keep problem solving.

Emma, thanks for joining us.

And we'll see you again soon.
