(gentle music) - It's game day, everybody.

Are you ready for some math time?

Because I am.

I'm so glad that you are here with us today, because I have an awesome game I wanna show you.

So let's get started.

We have an awesome game I wanna explain, and all you're gonna need, you can play right along at home or wherever you may be, you're just gonna need a pair of dice, if you have them, or if not, you could even just write some numbers, one to six, on some pieces of paper, kind of tear them up and put them in it in a bag or in a box, and you could just pull those out, and that would be your number.

It'd be the same thing as rolling that dice.

Now, I want you to play too, so what we've done is I'm going to go for me and I'm gonna roll mine and we're gonna do my turn, but then you're gonna have a chance to play too, and we're gonna see who wins, and if it's me or you.

So I'm gonna go for my first roll, and we're gonna roll both of these, all right?

Let's see what we get.

All right, that one's for me, and look what I got.

I got two twos.

So a two and a two.

So what I'm gonna do is I'm simply just going to write that down, and what I need to do is I need to add those up.

How much do I have altogether in total?

So I know that I have a two and I have another two, okay?

Well, let's think about that.

Two plus two, if I add two onto two, I'm up to four.

You got it.

Okay, so that's my first scores, I get four.

All right.

Now it's your turn.

Now, I'm gonna roll for you this time, but again, you could play right along wherever you're at.

So I'm gonna roll.

Are you ready?

Let's see what you get.

Oh, you got a two and a six.

All right, good job.

So let's write those in.

So you have a two and a six.

Okay.

Now, again, we need to add these up to see your total, all right?

And you could say two plus six, but remember, with addition, does the order matter?

We could also do six and two.

So if I count on from six and I add two more, I'd have seven, eight.

Okay, so you have eight in total.

All right.

So now let's compare our numbers.

Remember what I got?

I got a four, and you have an eight.

So which one was larger?

Okay, well, the eight is larger.

So you have the larger number, but how could we show that?

What's a way that we could write out in maybe the notation to say that eight is larger than four?

Remember those symbols, we have less than, greater than, and equal to?

Well, we can put those right in the middle.

So I know that four, my answer, my total, was less than eight.

And you had the larger number.

So guess what?

You win that round, but let's try again and let's see if I can come back in this one.

So that's one way you can play and you can keep going, and you can keep adding those up and see those totals, but a second way you can play is instead of adding the numbers, we could work on subtraction.

So let's take a look if we were to play with subtraction.

So I'm gonna go first again.

Are you ready?

I'm gonna do my roll.

So here we go.

I've got a five and a three.

Now, a little advice here.

I would always put the larger number first for this game while we're playing, okay?

If we're doing subtraction.

That's just for subtraction, but I'm gonna say that five minus three.

Okay, and again, we still wanna come up with a total.

So what do we have altogether?

If I say five minus three, okay?

Take three away from five and I'm left with two.

So I only have two.

Okay, now it's your turn.

You get to roll again.

So we go back to you and we're gonna use our dice.

You ready?

Here we go.

Oh, it's really close.

Do you see that?

You have a five and a two, a five and a two.

Okay.

So remember, when we do this, we're gonna do the larger number first, so I'm gonna put five first for you.

Five minus that other number, and we had a two.

And what do we have when we subtract those together?

Well, again, taking away, subtracting just two from our five, if I go backwards, let's count backwards by ones.

You ready?

So if I'm at five, I go back one, I'm down to four.

I go back one more, I'm down to three.

And you have three.

Okay.

So let's see.

let's compare these numbers.

I had a two, you had a three.

We're really close, but two is, what's that symbol I should use?

It's less than.

Two is less than three.

You had the larger number again.

Congratulations.

So that's the game that we had today.

I hope that you find someone that you can play with, whether it's a friend, a family member, or somebody close by.

And again, you don't need a whole lot of materials for this.

And if you don't have dice, you can use pieces of paper or whatever you have around you to play this.

But work on adding those numbers together, work on subtracting those numbers and comparing the two together.

So I hope you had fun, 'cause I sure did.

And keep learning and keep problem-solving, and we'll be back again real soon.
