- Hi, kindergarten Math Mights.

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

Today, I have some very fun activities for us to try.

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

Today, we are going to do a mystery math mistake, and we're gonna practice learning the names of shapes.

Oh my goodness, they're all mixed up.

All of our Math Might characters have their strategies confused.

We're gonna have to help them fix their strategies.

Here's how it works.

We are gonna have our friend Dotson come, and he was given a problem.

He tried to solve the problem.

We're gonna take a look at how he solved it, and we're gonna have to decide, did he do it right, or was there a mystery math mistake?

If there was a mistake, we have to help our friend Dotson fix it.

Here's what Dotson had to do.

Dotson made some different number lists.

He took numbers, and he wanted to put them in order.

He did it three different times.

A, B, and C are what he came up with.

Do you agree, or do you see some mistakes to make mystery math mistakes?

Our friend Landon is here to help us share his ideas.

Landon said that in the letter A that he thinks that seven should not be there.

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

So Landon looked at letter A, and he noticed that the seven should not be there.

Let's go and count.

So here we have one, two, three, four, five.

That does sound right.

I think Landon was right.

We need to get rid of the seven.

Let's cross it out.

So we're gonna get rid of this seven.

That way it's not in the order lineup.

Now our friend Ryan is here.

Ryan looked very carefully at letter B.

He said that letter B doesn't start at one, but if he counted up starting at three, then nine shouldn't be there.

It should be three, four, five, six, seven, eight.

Let's take a closer look.

So Ryan noticed that here we have three, four, nine, five, six, seven.

Did that sound right, Math Mights?

Let's take out the nine, and see how it works.

So we'll cross out the nine.

Now we have three, four, five, six, seven.

That's it, that's how it starts.

Even though we didn't start counting at one, it's still the correct order, we just started by counting at three.

Let's see if we can figure out the last one.

On the last one, letter C, we have three, eight, four, five, six, seven.

Hmm, that didn't sound right.

Did you see the mystery math mistake?

What number didn't belong?

That's right, Math Mights, it was the eight.

We need to take it away.

So we're gonna cross out the eight.

That way we have three, four, five, six, seven.

Great job, Math Mights.

You were able to help order all of the numbers in their correct order.

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

I can describe and learn the names of the shapes.

Take a look at this work mat I have here.

On it are four different shapes.

Do you know their names?

Let's take a closer look, as we play a game, and help sort our shapes.

So here is the mat with the four different shapes.

The first shape I noticed right away had three sides and three corners.

That's called a triangle.

Say it with me, triangle.

Let's look at the next shape.

The next shape is very round.

There are no sides, and no corners.

Do you know that one?

That's a circle.

Let's keep going.

This shape has four sides and four corners.

But I noticed that two are long, and two are short.

Do you know what that's called?

That's called a rectangle.

Can you say that?

Rectangle.

Let's look at the last shape.

The last shape is almost like a rectangle, because it has four sides and four corners, but all the sides are the exact same length.

That shape is called a square.

Can you say it?

Square.

Now that we have all of our shapes and names, we're gonna play a game.

Here I have a stack of shapes, and as fast as we can, we're gonna flip them over, and try to make 'em match.

Are you ready?

The first shape I have is this, that's a rectangle.

Four sides, four corners, two are long, and two are short.

Let's flip over this one.

Mm, let's see, that's a triangle.

There it is.

Let's do the next one.

Do you see where it goes?

That's a rectangle.

Great job.

Keep going, Math Mights.

Take a look at this one.

Well, it's all rounded.

That must be a circle.

Now I have this one.

Four sides, but they're all the same.

That means it's a square.

Now look at this one.

That one is a circle.

How about this one?

Three sides, that's a triangle.

You're doing a great job, Math Mights.

Let's finish the game.

Now I have this shape.

That's a rectangle.

And this, that one has three.

That's a triangle.

And now I have this one.

Hmm.

That one looks like a square.

And our last one, that is a circle.

Did you notice something, Math Mights?

Was every shape exactly the same?

I noticed that some of the shapes were bigger, some were smaller.

I also noticed that they didn't all sit the same.

Sometimes they were turned, but they all had the same attributes, meaning they had the same sides and corners.

Some were rounded.

And if all of those attributes are the same, size doesn't matter, neither does the orientation.

That means which way they're turned.

So a square, even if it's turned, is still a square, and a small circle is still a circle, even if it's a big one.

Now, Math Mights, let's go on a shape hunt.

Take a look at this picture.

How many of each shape do you see hidden in the picture?

Our friends, Ryan and Landon, are back to help us see all the shapes in the picture.

Our friend Landon noticed that he saw two triangles on the dog's ear.

Let's take a closer look.

He noticed that there were two triangles.

One here on this ear, and one here on this ear.

Let's count them.

One, two.

There were two triangles in the picture.

Great observation, Landon.

Let's hear from Ryan.

Our friend Ryan said he saw two squares on the dog's paw.

Let's take a closer look.

Ryan noticed that the dog's paws were the shapes of squares.

We can trace them, one, two.

Do you see any more?

Nope, just two, two squares.

Now I wonder if you could help me find the circles.

Let's take a closer look.

When we look for the circle, do you see any in our picture?

I noticed here, the dog's eyes.

Those are red.

Now let's look here.

Did you see the three on his cheek, and three on this cheek?

Let's count them.

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

There were eight circles.

Great job, Math Mights.

I wonder if we can find all the rectangles.

Let's take a look.

I'm looking.

Oh, I noticed right here on his leg.

That's a rectangle, and the other leg is a rectangle.

Hmm, do you see any more?

I, here, his whole body is the shape of a rectangle.

And look at that.

Do you see his nose?

That's also a rectangle.

Let's count.

One, two, three, four.

There were four rectangles in the picture.

That was so much fun, Math Mights.

Let's do another shape hunt.

Take a look at this picture.

How many of each shape do you see hiding in the picture?

Let's take a closer look.

I think we should start with this shape here, the triangle.

How many triangles do you see?

Let's see, we have one there, here's one.

Hm, do you see any more?

Oh my goodness.

Look, Math Mights.

Every ray of the sun is a triangle.

I think we should do our touch and count method.

So as we do it, we'll touch, and then we'll start our counting.

Count with me.

One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13.

There were 13 triangles.

Great job, let's do the next shape, the circle.

Here's the circle.

How many do we see?

Well, I noticed this was a circle here, and here's a circle.

Oh, and the wheels on the car.

Let's count them.

One, two, three, four.

There are four circles.

Great job, now onto the rectangle.

Here is our rectangle.

How many do we see?

I noticed there's a rectangle.

The house is made of a rectangle.

So is the door, look at the grass.

The grass is a long rectangle.

Hm, do you see any more?

Let's count them.

Oh, there's one, the other tree trunk.

Let's count.

One, two, three, four, five.

There were five rectangles.

Onto our last shape, Math Mights, the square.

Let's see, here's our square.

I noticed the windows.

One, two, and the windows on the car.

Three, four, there were four shapes.

You are getting so great at noticing shapes around us.

Now we're gonna play a game called connect the dots.

I have a pattern here with some big red dots on it.

Those red dots will be the corners of our shape.

As you see them, I want you to try to guess what shape it will be.

Then I'll connect the dots, and we'll see if you were right.

Take a look at this one.

Did you notice the three red dots?

I wonder what shape it will be when I put the sides on.

Do you know?

Let's see if you're right.

So I'm gonna connect the red dots straight to the red.

Now, this red to here, and this one to here.

Do you know that shape?

That's a triangle.

Notice it has three corners, and three sides.

Now it's your turn, Math Mights.

You are going to get to go on a shape hunt.

Take a look at your picture, and carefully see if you can find and count all of the shapes.

Great job today, Math Mights.

We did the mystery math mistake, and we practiced knowing all of our shape names.

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