(playful music) - Hi everyone, welcome back.

My name is Mrs. Gray, and I can't wait to do more math with you today.

Today, we're gonna be doing a numeracy talk with our friend Dotson.

We're also gonna be practicing matching some expressions and some drawings together.

Get ready, we're gonna warm up our brain with our friend Dotson.

Here he comes now!

Today, Dotson is gonna be showing a numeracy talk with the counting buddy.

When the counting buddy comes on your screen, you are going to be taking a picture with your brain.

Try to remember how many beads are on the counting buddy.

But today, I'm not just gonna ask you how many beads, today, there will be a secret question after we see the counting buddy.

Oh, here he comes now.

I wonder how many beads were there.

Now the secret question today is how many beads were there if there was one more?

Let's take a look at what some of our friends had to say.

Our friend Keira thought that she saw one more that would be six.

Our friend Maggie thought that one more would be seven.

And our friend Colton thought that one more would be eight.

Let's take a closer look at what our friend Kiera saw.

Kiera saw seven and she thought that one more would be six.

Do you agree with Kiera?

Do you disagree?

Let's hear what Colton has to say.

Colton said that he politely disagreed with Kiera.

He thought that it had to be seven so one more would have been eight.

How about we take a look on our counting buddy to see Colton's thinking?

Colton saw seven beads on the counting buddy.

So one more would have to be eight.

Wow, kindergarten Math Mights.

You did a great job on that numeracy talk with the counting buddy.

Our friend Dotson would so proud of how hard you're working.

Let's take a look at our I can statement for the rest of today.

Our I can statement is I can match expressions to drawings.

I have something to show you.

I want you to look at this.

What do you notice?

What does this make you wonder?

Well, I see some chips.

I see some are red and some are yellow and I see that the number under it also matches.

I see the three red and there are two yellow.

And I also see the addition sign.

That means that they're gonna be putting those numbers together.

I want you to be thinking about that as we keep going in our show.

Take a look at this drawing.

This drawing has an expression.

Maggie said that she thinks that this expression matches the drawing.

What do you think?

Do you agree with Maggie?

Do you politely disagree with Maggie?

Let's take a look and act out Maggie's thinking.

So Maggie saw six chips.

She thought that two chips were taken away.

Well, that expression doesn't really match what's going on here because what I see is I see the four red chips and I see two yellow chips.

It looks to me like they had four and they got two more.

I think that this might be an addition problem.

I think the expression that Maggie meant was four plus two equals six because none of the chips were taken away so it can't be a subtraction problem, this has to be an addition problem.

Wow, Math Mights, you did a great job helping me help Maggie figure out what expression matched that story.

Now we're gonna get to play a game and this is gonna be a matching game.

We've been talking a lot about expressions and about drawings and today in our memory game, we're gonna be flipping over cards to see if we can match the right expression with the right drawing.

So I'm gonna be picking up two cards and I'm gonna flip them over.

So there's our drawing and there's our expression.

We have to decide if that's the match.

Let's look closer.

Here, I am seeing seven circles.

Here, I am seeing six minus three.

Well, I know that one doesn't match because there's no subtracting going on in our drawing.

None of the chips have been taken away.

So I'm gonna put that expression back and see if I can find the right expression to match the drawing.

Let's try this one.

I think we might have a match, let's double check.

This says seven plus zero.

Here, we have seven dots and there's zero more being added on.

I know there's none being added on because there's no dots of a different color or separated by a line, so that means that zero more came to the seven.

That means we have a match.

Let's move that match out of the way and try for another one.

Let's try this card and let's try this one.

Well here, this says nine minus two.

And this is the drawing.

Do you think that matches?

No, I don't think so either because none of the chips have been taken away.

Let's try for another expression.

Let's try this card.

I think we might have a match.

Let's double check.

This expression says five plus three.

And when we look at our drawing, we have five on the top and three more.

That means we had five plus three just like on our expression.

We found another match, great job.

Let's keep going and see if we can get all of our matches.

We're gonna flip over one of our drawings.

Ooh, this one looks a little tricky, let's try this.

So this expression shows six minus three.

Well, when I look at our drawing, let's see, one, two, three, four, five, six, seven, eight, nine.

This shows that we started with nine and that doesn't match our expression because the expression says that we only started with six so that one is not a match.

Let's put it back and try again.

When we flip over this one, let's see.

I think we might have another match.

We started with nine just like in our expression.

And now it says take away two.

On our drawing, we can see that two of the dots have been crossed off.

That means there was nine and two were taken away.

That matches our expression.

We found another match, great job.

Let's keep going.

We're gonna flip this one and let's try this card.

So this expression says six plus three.

Well, I know right away that that's not a match because our drawing shows that there was chips taken away, not added to it so let's put that back and keep going.

Let's try this one.

This expression says six minus three.

That means there was six chips and three of them had been taken away.

We found another expression.

Great job, Math Mights.

Now we have one left.

I wonder if it will be a match, let's see.

So we have... Oh, we have some chips.

Oh, and we have the line showing the two different numbers that were put together.

Let's see if it matches.

One, two, three, four, five, six, and three more.

That means we have a match.

This drawing is showing us six plus three just like the expression.

Great job, we found our last match.

Wow, I can't believe how many matches we found.

We were able to look at the drawing and the expression and put them together.

Now we're gonna get ready to get out our magnifying glass.

A magnifying glass is something that you might look through to help you see things that are very small.

It might help you to really look close at what we're doing.

So we're going to be trying to find more matches of drawings and expressions.

This example shows us four plus three.

Do you think the drawing matches?

I do too.

It shows four and then the line to show the other number, which is three and it shows that four and three were put together.

We're gonna be doing some more examples of some expressions and some drawings.

Let's take a look at our first expression.

Our first expression is five plus three.

How do you think we should draw that?

I think we should start with the five and draw it out.

One, two, three, four, five.

Then I can show the other number by drawing the line and drawing my three.

One, two, three.

I can see that five plus three is eight.

Five plus three equals eight.

Let's try it again using another expression.

The expression we're gonna use is going to be eight minus two.

How would we draw that out?

I think we should start with the eight.

Let's draw it.

One, two, three, four, five, six, seven, eight.

Now we can show that we are taking two of them away by crossing them out.

One, two, if we count what we have left, we have six.

I know it's six because there was five left on the top and one left on the bottom.

So eight minus two equals six.

Let's take a look at another example.

This example is gonna start with the drawing and we are gonna have to try to write the expression.

This is our drawing.

Well, I'm noticing right away that this must be an addition problem because none of the chips have been taken away so let's start with our first group of chips that are in black.

There are three black chips.

Then there are seven red, let's count to be sure.

One, two, three, four, five, six, seven.

There are seven red.

The expression that would match this drawing is three plus seven.

And if I add those together, that would be 10.

Three plus seven equals 10.

Let's do one more.

This is another one where we're gonna see the drawing and have to write the expression.

In this drawing, there are lots of circles here.

Let's count them to know how many.

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

We started with nine circles, let's write it, nine.

Now I know this is a subtraction because there are some that are crossed out.

Let's see how many are crossed out.

Can you count with me?

One, two, three, four, five, six, seven, eight.

There were eight that were crossed out, which means they were subtracted.

And I know if I had nine and I took eight away, there would be one left.

Nine minus eight equals one.

Math Might, you have been working so hard helping me match drawings with their expressions.

You are gonna get a chance to play the game more where we match the cards by flipping them over.

All day today, we worked very hard matching drawings to expressions.

I can't wait for you to come back and do more math with me.

I will see you soon.
