(upbeat music) - [Children] Math Mights!

- Hi Kindergarten Math Mights, my name's Mrs. Gray.

And I can't wait to do math with you today.

Today, we are going to be doing a numeracy talk with our friend Dotson, and we're gonna be working with the numbers 11 through 19.

Those are our teen numbers.

Our friend Dotson is coming today to do our numeracy talk.

(air whooshing) Now today, when he does his numeracy talk, we're going to be using the counting buddy senior, that means there will be 20 beads on his buddy.

10 will be in one color and 10 in the other.

So when Dotson shows us our secret counting buddy, you are gonna be taking a picture and try to remember how many beads you see on the counting buddy.

Get ready, here comes our famous counting buddy now.

Did you see the counting buddy?

How many beads did you see?

I think we should take a closer look and hear what our friends Nora and Laila have to say.

Our friend Nora said she saw 15 beads because she saw 10 of one color and five of another, 10 and five more equals 15.

Let's take a closer look at Nora's idea.

So here is our counting buddy.

Remember, when we wanna see him, we move him over, and anything by his head, we pretend is invisible.

So Nora said she saw 10 beads of one color, and then she saw five of the other color.

She knew that 10 and five more was 15.

Great job, Nora.

Laila saw 15 too, but she saw at a different way.

Laila said that she saw 15 because she noticed that there were five beads up by the counting buddy's head.

Let's take a closer look.

So Laila saw the five beads up here, and she knew that on the whole body there was 20.

And if the five were up here and they were invisible, that means there would be 15 left, 15 because five were gone.

Great job Math Mights, did you see it one of the ways that Nora or Laila saw it, or did you see it one of your own ways?

Here is our I can statement for today.

"I can show numbers with 10 frames and dots or counters."

Today, our friend Nora is having a problem.

She has to build some numbers.

Now she is gonna be building different numbers like this one.

This is the number 11.

In this game, create the teen number, Nora is going to have to figure out how many dots to use to build the different numbers.

What do you think, Nora?

How would we build the number 11?

Nora said, to build the number 11 we're going to need a full 10 frame.

And then to make it 11, we're going to need to add one more so that we can get the right number.

So let's take a closer look.

Here is our one 10 frame.

This can be called one 10.

And Nora said to make the number 11, we would need to add one more.

10 and one more is 11.

Nora also thinks that we should use our friend value pak.

Are you ready?

Can you help me call?

The value pak.

- [Value Pak] Ooh-hoo.

- Our friend Value Pak is an amazing Math Might character.

He can be broken up into the different place value.

Let's take a look at the number 11 as a value pak.

So here is the number 11.

Now we can take it and we can break it.

Here, it becomes 10 and one more.

Hey, that's just like what we built on our 10 frame, 10 like this, and one more.

When we put it back together, we can see that that is the number 11.

That was so much fun.

Let's build another number.

The next number is the number 15.

Our friend Laila has an idea of how to build the number 15.

She said that we should be building a full 10 frame.

And if we want to make 15, we will need to add five more.

Let's take a closer look.

Here is our one 10.

And she said we need five more, one 10 and five more is 15.

Let's get our friend value pak to help break it down.

Here's the number 15.

One group of 10 is here, one 10.

Here is our five more, five ones, one 10 and five ones, when you put it together is the number 15.

Great job Math Mights, Let's do another one, this is the number 17.

Can you say it?

Say 17.

Let's take a closer look at the number 17 to build it.

Here is the number 17.

We can break the number 17, and we can see that 17 has a 10 and seven more.

So we already have our one 10.

Now we need to make our seven ones.

Here is our seven ones.

One 10 and seven ones is the number 17.

Great job, Math Mights.

We were able to build so many teen numbers.

We were able to see that every teen number had one 10 and some ones.

Get ready, we're gonna be playing a new game.

This game is called teen bingo.

Here's how it works.

In front of me, I have a double 10 frame to build my numbers on.

I have the rekenrek to build the numbers on.

I also have my game board, and my calling cards.

We are gonna flip over the first calling card.

That's the number 16.

16 is one 10 and six ones.

Let's begin by building it on our double 10 frame.

So first we're gonna build our one 10.

That means every box in the top 10 frame will have a dot in it.

Now we're gonna build our six ones.

Here is our one 10 and six ones for 16.

Now we're gonna use our rekenrek.

Remember, when we clear the rekenrek, we slide the beads all the way to the right which is also the side with the white.

To count the beads, I have to slide them over.

And just like on our counting buddy, any beads left on this side, we just pretend they're invisible.

So let's build our one 10.

That means all the beads are on the top since there's 10 beads on the top bar.

Now on the bottom bar, we're gonna build our six ones.

I'm gonna build five and one more.

That is the number 16, one 10 and six ones is 16.

Now take a look at our bingo card.

We are looking for the number 16.

It might be built on a double 10 frame like we did here, or it might be built with the beads like on our rekenrek like we did here.

Hmm, do you see it, do you see 16?

There it is, it's built like on our rekenrek.

10 and six more.

So I'm gonna take one of my chips and cover it.

That way, I know I already found the number 16.

That's so fun.

Let's do our next calling card.

Our next card is the number 12.

I'm gonna clear my board, but I think I'm gonna leave my 10 because I already know that there is one 10 and two more.

Here is our one 10.

And now we're gonna build two more.

One 10 and two more is 12.

Let's build it on our rekenrek.

To clear the rekenrek, move all the beads over to the white side.

We're gonna build our one 10 and two more.

There's 12, take a look at our bingo card, do you see the number 12?

Hmm.

Oh my goodness!

That means it's not on our calling card, and that's okay because when you play bingo some of the things called might not always be on your card.

So we're just gonna keep going to our next number.

Clear our double 10 frame.

And I'm gonna clear the rekenrek.

Call the next card, is 18.

18 is one 10 and eight more.

We already have our one 10.

So now we need to build eight more.

One 10 and eight more is 18.

Now go to the rekenrek, we're gonna build our one 10 and eight more.

I noticed down here there was five and three, so I'm going to use that to build our eight.

There it is, 18.

Let's go over to our recording sheet.

Take a look.

Hmm, do you see it?

Oh, there it is.

Because look, there's two empty boxes just like over here.

Here's our one 10 and eight more.

That's the number 18.

Let's go to the next card.

The next number is 17.

17 is one 10 and seven more.

There is 17.

On the rekenrek, it would be one 10 and seven more.

Let's find the number 17.

Looking for the number 17.

Oh, here it is, 10 and seven more, just like we built on our double 10 frame.

Let's add our chip.

We're getting close to our bingo because we almost have three in a row.

Let's keep going.

I'm gonna flip my card, clear the double 10 frame, clear the rekenrek.

Here is the number 13.

13 is one 10 and three more.

One 10 and three more is 13, 10 and three more.

Let's take a look at our bingo board.

We're looking for the number 13.

Here's the number 13, 10 and three more.

Hmm, look at what else I noticed.

Here's the number 13 too, 10 and three more.

Now I get to make a decision of which of the boxes I want to put my counter on.

Remember, the goal is to get three in a row.

So if I look, I could put it here and get three in a row, or I could put it here and get three in a row.

I think I'm gonna put it here just like on our rekenrek and get three in a row.

That means I won the game.

Now it's your turn.

You are going to get to play the teen number bingo game.

I hope you had a great time today Math Mights.

Today we did our numeracy talk and we built our numbers that were teen numbers, 11 through 19.

I can't wait for you to come back soon.
