(Playful music) (Cartoon sound effects) - [Children] Math mights!

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

Today, I have some exciting math activities for us to try.

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

Today, we're going to be doing a numeracy talk with our friend Dotson, and then we're going to be looking at written numbers with groups.

Dotson is going to come today to help us warm up our brains.

When he comes, he's going to be showing us a number of dots in a 5 frame.

Now, today, we're going to do something a little tricky.

When you see the dots on the 5 frame you're still going to take your picture with your camera in your brain.

But, today I don't want you to tell me how many dots there are.

Today, we're going to use an empty 5 frame and you're going to be building it.

However, there is going to be a secret question when I ask you to build it.

So take a good picture.

Here comes our friend Dotson now!

(Suspenseful music) Dotson brought our famous 5 frame.

Here it is!

(Camera clicking) Now, I want you to build 1 more than what you saw.

That's kind of tricky, math mites Our friend Maeve and our friend Keisha are here to help us today.

Maeve said that she built 3 on her 5 frame mat.

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

So when Dotson showed us the 5 frame, it was horizontal like this, but remember you can always turn your 5 frame to make it vertical, and it won't change how the dots are in the 5 frame.

Maeve said that she saw at 3 and she built it like this.

Hmmm, remember the secret question was: build 1 more.

Do you think Maeve did that?

Let's see what our friend Keisha did.

Keisha said she put 4 on her 5 frame mat.

Let's take a closer look.

Keisha said she had the 3 and she put 1 more to make 4.

What do you think?

Do you agree or disagree with Keisha and Maeve?

I agree with Keisha.

She saw the 3 that Dotson showed us and she remembered the secret question was: put 1 more.

So she built 4.

This way, she was able to show the 3 and 1 more.

Let's see if we could make it into a number bond.

So we can take our whole or total number and put it at the top of our number bond.

That would be 4, 4 total.

Now we can show our 2 parts.

Dotson originally showed us 3 dots on our 5 frame.

And then, there's another part, that would be the 1 more.

If we had 3 and 1 more, put it together, that makes 4.

Let's act it out, 3 and 1, make 4.

Can you do it with me?

3 and 1, make 4.

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

I can match written numbers with groups of objects.

Today, we're going to be doing an exciting activity with mystery bags.

Which bag is going to match each of the different numbers?

So, what we're going to do is, I have bags with different labels.

This is going to be bag A.

Inside, there's some mystery objects.

We're going to dump out those mystery objects, arrange it on a 10 frame, figure out how many, then on our recording sheet, we're going to record where bag A would match according to how many are inside.

Let's get started.

So we're going to take A, dump it out.

Inside, I have some little animals.

We're going to put them on our 10 frame.

How many animals are there?

Hey, that one was pretty easy because all the boxes on the top are filled.

That means there's 5.

I didn't even have to count it.

I was able to subitize.

Now we're going to record the letter A, next to the number 5.

Find 5, to show 5 number of objects that was hidden inside bag A.

Now we're going to clear the board and go to bag B.

Here is bag B, let's dump it out.

Inside we had some pretzels, arrange it on our 10 frame.

How many objects are there?

That's right, there's 3, because there are 2 empty boxes, 3.

We're going to record bag B, next to the number 3.

Clear the board.

Let's do bag C. Dump it out.

Inside, there's only 1.

Let's arrange it on the 10 frame.

Bag C was for 1 object.

Let's go to the next bag.

Dump it out.

Inside arrange them on the 10 frame.

How many objects?

There are 4 objects.

So, next to the number 4 , we're gonna write D, to show bag D had four mystery objects.

Let's try another bag.

We're going to go to bag E. Dump it out.

We're going to arrange it on our 10 frame.

How many are there?

That's right there, there's 6, 5, 6!

Next to the number six, we're going to write E. Bag E had 6 mystery objects.

Here's the bag F, dump it out.

We're going to arrange it on a 10 frame.

How many shells do you see?

That's right, there's 9.

I saw 9 because I noticed right away there was 1 empty box, and if every box was filled, it would be 10, but with 1 missing, it's 9.

So next to the number 9, I'm going to write bag F. Let's try another bag.

Let's get bag G. Inside, we're gonna dump out our mystery objects and there are some donuts.

Let's put our donuts on the 10 frame.

How many donuts do you see?

There are 7: 5, 6, 7 on our recording sheet.

Next to number 7, we're gonna write bag G. Clear the board and go to bag H. Dump it out.

Let's arrange it on the 10 frame.

How many animals do you see?

There's 8, because there was 2 empty boxes, 5, 6, 7, 8.

When you do your mystery bags, you can keep going until all of your bags have been counted and you match which bag would go to which number for the objects.

Now we're going to get to play another game.

In this game, we're going to be practicing matching groups of images to the numbers.

It's going to be very similar to our mystery bag, but this time there are drawings on a page for us to count, and then we'll match it to the number.

Here we go math mites.

We're going to start at the top with the blue circles.

Let's do our touch and count strategy.

1, 2, 3, 4, 5, 6, 7.

Now we're going to draw a line to show 7 was for our blue dots.

Let's go down to our next group.

Our next group, I am going to count going down.

1, 2, 3, 4, 5, 6.

Find the number 6, there it is.

Draw a line to show 6 pink polka dots.

Now we have a 10 frame.

Hey, we can just look at the top, 5, 6, 7, 8.

There is 8.

Find the number 8, there we are, and draw a line to match it to the 8 on the 10 frame.

Now we're going to count the group of white circles.

Counting in a circle can be kind of tricky because sometimes we forget where we start and we could just go around and around.

So we are going to be using a marker and I'm going to put a little polka in each of the circles that I count so I remember where I started.

Here we go.

I'm going to start here.

1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

There was 10 circles.

Let's find the number 10.

There it is.

Draw a line to match it to the circles.

Now the next one.

Hey, it's our 5 frame, but 1 is missing, that means there's 4.

Did you subitize that?

Yes, let's match it to the 4.

There's the 4 right up top, 4 will match up, here to the 4.

Amazing Job math mites.

You were able to help me figure out which groups would match to which of the corresponding numbers.

Now we're going to get to play a game called Deck O' Dots: Train!

And in this game today, we're going to be using our yellow Deck O' Dot cards.

These cards have our 10 frames on them.

When we flip it over, we're going to be matching the number of dots on the card to the corresponding train car that will have the numbers.

Are you ready to help me play?

So, we're gonna take our card and flip it over.

How many dots do you see?

That's right, it's 10.

I bet you use subitize and noticed that every box had a dot.

Now let's put it on the 10 car on our train.

Onto the next card.

How many dots do you see?

5, 6, 7, 8.

Let's match it to the 8 car.

Next card.

How many dots do you see?

5, 6, 7, 8, 9.

Take it, match it to the 9 car.

Flip over the next one.

Hey, I don't even need to count that one.

I saw right away, 5 and 1 more.

I know it's 6.

We're going to take the 6, and match it on our 6 car.

Let's try the next card.

5, 6, 7.

Take it, match it to the 7 car.

Let's try the next one.

How many dots do you see?

That's right, there's 2.

Take it, match it on our 2 car.

Flip over the next card, how many dots?

That one is a 1.

Hey, that's just like earlier, we talked about being able to turn your frame.

It will not change how many dots there are.

Let's take the 1 and put it on the 1 car.

Take the next card.

How many dots do you see?

That's right, there's 3.

Where's the 3 car?

There it is, 3.

How many dots do you see?

That's right, there's 4.

I knew that right away cause I saw the 3 and now I see 1 more.

4 goes on the 4 car.

Our last card has 5 dots.

I know that right away, all the boxes on the top had a dot, did you see it too?

Let's match it on the 5 car.

That was so much fun math mites.

Now it's your turn.

You are going to get to play Deck O' Dot Train, using the 10 frames.

Be careful to match the right number of dots to the right car on the train.

Great job today, math mites.

I love how hard you work doing our numeracy talk and matching the groups to the different numbers.

I hope you had fun and I can't wait for you to come back soon.
