- Hi, kindergarten Math Mights!

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

Today I have a lot of fun and exciting activities for us.

Let's take a look at the plan for today.

Today, we're going to do a mystery math mistake and we're going to practice identifying shapes that are the same.

(mysterious music) We have all of our characters here from Mathville, but look at them!

Oh no, they're all mixed up.

Let's take a look at how we can help them today.

In our Mystery Math Mistake, our friend Dotson had to try to solve a problem.

And we're going to take a look at what Dotson did.

After we see what Dotson did, we're going to decide if he did it right or if he made a Mystery Math Mistake.

If we see a mistake, we're going to have to try to fix it to help him.

Let's take a look at what Dotson did.

Dotson needs your help.

He was shown this on the counting buddy.

Then he was told to show one more on a 10-frame.

Here's what he did on his 10-frame.

What do you think?

Did Dotson do it right?

Or did he make a Mystery Math Mistake?

Let's take a closer look at what he did.

So Dotson had this counting buddy and he built it, and then he had to take what he thought and he had to build it on his 10-frame.

Today, I have some friends here to share their ideas of what they think happened.

Our friend Landon was here.

Landon said that Dotson made six on his 10-frame, but the counting buddy had seven.

Hmm, let's take a closer look at Landon's thinking.

So Landon said that on the counting buddy there was seven, and I can see that, I see the group of five and two more; there was seven.

And then on the 10-frame, our friend Dotson built this to make it six.

But do you remember the secret question?

Dotson was supposed to build something with one more.

Did he do it?

Let's hear from our other friend.

Our friend Ryan is here.

Ryan said that Dotson built one less on his 10-frame instead of one more; it should be eight and not six.

Hmm, that was a good observation Ryan, let's take a closer look.

So the secret question said one more, and if we had seven here, and Dotson built this, well, let's see what happens when we put one more.

There is seven, just the same as the counting buddy; seven and seven.

And Dotson was supposed to add one more, which would be eight; five and three is eight.

I think Ryan was right, Dotson made a Mystery Math Mistake.

He did one less because he took one away instead of putting an extra chip to make one more.

Let's take a look at our "I Can" statement for today.

"I can find shapes that are the same."

Take a look at this picture.

Do you see the friends having a game day?

What kind of games do you play with your family?

My family loves to play board games.

We love to play clue, we love to play monopoly, all different fun board games; I hope you do too.

Take a closer look at the picture.

What shapes do you see?

Let's go down to my work mat as we look for our shapes.

Looking here, there's all different kinds of shapes.

How would you describe the different shapes?

Today, I have some friends here with me that are going to help us see what they observed in the picture.

Our friend Landon said that he saw a circle, as the sun, because it is round.

Let's take a closer look at Landon's thought.

Landon said that he noticed up here there was a circle, and this shape was round; there are no sides to that shape.

Do you see any more circles hiding in the picture?

There's some, on the balloons.

Did you notice any more circles?

How about over here?

The plate for the pizza.

Our friend Ryan also saw some different shapes.

Ryan said that he saw triangles for their hats, and they look pointy.

Let's take a look.

Here are the triangles that Ryan saw.

He said that they were pointy.

Look at how they come together and make a point on the ends.

Do you see any more triangles?

There's some on our backgammon game.

There's a lot of triangles on the game.

Wow Math Mights!

That picture with filled with all types of different shapes.

Some shapes were round, some had pointy corners, some had three sides and some had four.

Have you ever noticed that in the world you live in there are different shapes all around you.

Take a look around the room you're in right now.

How many different shapes can you see?

Everywhere that we go on an adventure, we'll see all different types of shapes.

The important thing in kindergarten is that we can start to describe the shapes.

We can use description words like round, sides, corners.

Being able to describe the shape will help describe what shape it is and help explain it to other people.

Take a look at this picture here.

Here I have four different buttons to show you, which button doesn't belong?

Remember, just like when we did the shapes, look carefully, really tried to describe it, and it might help you figure out which one doesn't belong.

Our friend, Landon and Ryan, are here.

They have an idea which one doesn't belong.

Our friend Landon said that letter C doesn't belong, because it's not round; it looks like a flower.

Let's take a closer look at Landon's thinking.

So looking down here at our four different buttons, our friend Landon said that this one didn't belong, because all of these are round.

And this is the only button that was not rounded, it had more of a flower shape to it.

That was a good observation Landon.

Let's hear from Ryan.

Our friend Ryan said that letter A didn't belong, because letter A is not blue, it's green.

Let's see what Ryan had to say.

Ryan said that he noticed that these three buttons were all the color blue and this one doesn't belong because it's green.

That was a good observation Ryan.

What do you think Math Mights?

Do you agree?

They have some more ideas to share.

Landon now, he thinks that maybe B doesn't belong, because it doesn't have four circles in the middle, it only has two.

Let's take a closer look.

When we're looking at the buttons, he noticed that on letter B, there are two circles in the middle.

Those are like the holes that we would sew a button on with.

But these three all have four circles in the middle.

Hmm, I'm not sure which one doesn't belong yet.

Let's hear from Ryan again.

Ryan said that maybe letter D doesn't belong, because it's not big, it's small.

Let's take a closer look.

When we're looking at all the buttons, A, B and C are all about the same size.

And Ryan noticed that D was a lot smaller, and he said maybe D doesn't belong.

So what is it Math Mights?

What do you think?

I think that maybe each of them has their own reason for why they don't belong.

But you did an amazing job really taking a close look at the shapes and being able to spot some differences and how they might be similar and how they might be different from one another.

Math Mights, you are getting so great at looking at the different attributes, or the different ways to describe shapes.

Let's play a game.

This game, we're going to be matching shapes to objects that have the same shape.

Are you ready?

I'm going to need your help for this one.

Let's take a closer look.

So here on my page, I have four different objects from our birthday picture earlier.

Here, I have a pizza and a rug and a birthday hat and a napkin.

And over here I have four different shapes.

We'll get to the names of the shapes in a little bit.

But what we're going to be doing is we're going to be looking at which object needs to match which shape.

Remember that big word?

Attributes.

So when you look, see how the shapes are the same.

Look for rounded edges, look for sides or corners to help you try to match.

Let's get started.

So here, let's start with the pizza.

Hmm, I notice that the pizza is very round.

I do not see any sides with corners on that.

Does that match that shape?

No.

How about the next shape?

There it is!

This is a circle.

The pizza is in the shape of a circle.

Notice how they're both round with no sides and no corners.

Now let's go down here to the rug.

Hmm.

Well, this one has four sides.

Hey, that's just like this shape!

This one has four sides.

But wait a minute, do those look the same?

I think they look a little different.

Let's take a closer look.

On this rug, I notice that these lines, that are parallel to each other, are very long and these ones are short.

And on this shape, they're all the same size.

Well, I don't think that's a match anymore.

Let's look at the next shape.

Hey, what do you think Math Mights?

I think we have a match.

This is a rectangle.

The rug is the same as a rectangle.

They both have four sides and four corners, but it has two long sides and two shorter sides.

Great job Math Mights!

Let's go to the next picture.

On this picture we have our party hat.

Hmm.

Well, I noticed right away there's no rounded edges.

Let's count how many sides there are.

1, 2, 3 sides.

And let's count the corners.

1, 2, 3.

Three sides and three corners.

Do you know what shape that is?

That's called a triangle, can you say that?

Say triangle.

Let's see if we can find it on our page.

The triangle, well it doesn't match that, because remember that had four.

We already matched those and (gasping) look Math Mights!

1, 2, 3 sides.

1, 2, 3 corners.

I think we have a match!

Let's put it together.

Draw a line, the hat to the triangle.

Now onto our last shape.

Here I have a napkin.

Let's count the sides.

1, 2, 3, 4.

(gasping) Math Mights!

Do you remember?

The shape on the top?

That also had four, let's see if it's a match.

Up here we had 1, 2, 3, 4.

And look, all the sides are the same.

The napkin matches this shape.

That's called a square.

We've been working so hard at finding shapes that are the same.

Now it's your turn to play a game to count up how many shapes you can find that are the same.

Great job, Math Mights, you worked so hard today finding shapes that were the same.

I hope you had a great time and I can't wait for you to come back soon.
