(bright music) - Hi Kindergarten math mights.

My name is Mrs. Gray.

Welcome back to doing math with me today.

I'm so glad you're here.

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

We're also going to be comparing some word problems.

Get ready.

We're gonna be warming up our brain with our friend Dotson.

Here comes our friend Dotson now.

Today we're gonna be using our counting buddy, Junior.

Remember we used him last time.

Let's take a look at him to refresh our memory.

Our counting buddy Junior has a head up here and his feet down here.

When the beads are slid towards his head, we pretend those ones are not there.

To see a number, we are going to slide the beads towards his feet.

I'm gonna build a number to show you.

This is the number six.

I know it's six because there's five black beads and one pink bead.

Remember, these beads up here we pretend are not there.

Here comes our counting buddy now.

Try to remember how many beads you see without counting.

Let's see what our friends saw when they saw the counting buddy.

Our friend Anderson saw seven beads on the counting buddy.

Our friend Tenshi saw eight beads on the counting buddy and our friend Lysha saw six beads on the counting buddy.

Hmm, that was a few different answers.

I wonder which one you agree with.

Let's take a closer look at our friend Tenshi.

Tenshi said that she saw five and three more on the counting buddy.

Do you agree with Tenshi?

Do you disagree with Tenshi?

Hmm, let's take a look at what our friend Anderson says.

If he agrees or disagrees.

Our friend Anderson said that he politely disagreed with his friend Tenshi.

Anderson saw seven because he saw five and two more.

Let's take a look at our counting buddy to see what our friend Anderson saw.

Anderson saw seven.

He saw five and two more.

How about we go back and see the counting buddy to see what was shown on the screen.

Here is our accounting buddy.

Oh, I see our friend Lysha would like to change her answer from six to seven.

She was able to use Anderson's thinking to help her to change her answer.

Wow math mights, you did a great job on our numeracy talk.

Our friend Dotson would be so proud of us.

Now let's take a look at what we're going to do today.

Our I Can Statement for today is "I can figure out what's the same and different about story problems."

I want you to take a look at this video.

This video has some very cute penguins waddling around.

The penguins are on the shore.

Now I want you to keep that image of the penguins in your head.

They are going to help us when we move on to our next problem.

There were five penguins on the shore.

Then four more penguins swam in from the ocean to sit on the shore.

How many penguins are there now?

Let's go to our mat to act out our problem.

There were five penguins on the shore.

We're gonna be using our black linking cubes today to show the penguins, because remember, we can't go out and get real penguins to put on our mat.

That would be silly.

Can you count the five penguins with me?

One, two, three, four, five, then four more penguins swam to the shore to sit.

Let's add our four more penguins on our mat.

One, two, three, four.

How many penguins are there on the shore?

Can you count with me?

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

There are nine penguins now on the shore.

Now we're gonna try to do our organized quick draw to show the penguins from the problem.

We're going to dress circles to represent our penguins.

There were five penguins on the shore; two, three, four, five.

We're then gonna draw a line to separate our two numbers.

Four more penguins came; one, two, three, four, how many penguins were on the shore at the end?

Let's count; one, two, three, four, five, six, seven, eight, nine.

There was nine penguins in the end.

Now do you think we could write a number sentence that would match our drawing?

Let's do it.

There was five penguins on the shore.

We are going to add four more penguins that swam above that swam to the shore, which means there was nine penguins all together.

Here is another drawing of the problem that we just did.

We did five plus four equals nine.

Now I want you to try to remember this as we go into our next problem, we are going to be comparing them.

The next problem tells us that there was nine penguins on the shore.

Then four penguins jumped into the ocean.

How many penguins are now on the shore?

Let's go to our mat and build it.

There was nine penguins on the shore.

Can you count the penguins with me?

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

There was nine penguins on the shore and four of those penguins jumped into the ocean.

Remember to show that they have gone away.

We're going to move them off of our mat.

Let's move our four penguins into the ocean.

Count with me.

One, two, three, four.

There are now five penguins left on the shore.

Let's count to double check; one, two, three, four, five.

Now we're gonna try to do that organized quick draw.

Remember when we were counting we started with nine penguins on the shore.

Let's draw those penguins.

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

Four of those penguins swam in the ocean off of the shore.

Remember to show that, we can just put a line through them to show that they have gone away.

Let's cross out four of those penguins.

One, two, three, four.

Now we have five penguins left.

Do you think we can do a number sentence to go with our story?

Let's do it.

There was nine penguins on the shore.

Then, four of those penguins went into the ocean.

So we subtracted four.

And that means that there were five penguins left on the shore.

You did a great job helping me with that subtraction word problem.

Let's take a look at another representation of what we just did.

Here is our penguins.

And we showed the nine penguins.

We subtracted the four and that means there was five penguins left on the shore.

Those two last problems we did were both about penguins.

Let's see if we can compare them.

They both seem to have the same numbers.

We used nine and four, and five, but they were put together in different ways.

The problem that's on the top, that's in blue says that we added.

That means we took the two numbers and we put them together.

Five plus four equals nine.

The problem on the bottom was different because we started with the nine penguins.

We then showed that four of them went away.

That is a subtraction problem.

Nine minus four equals five.

Wow math mights.

You did a great job with those penguin word problems and comparing them.

Now I want you to take a look at this video of jellyfish.

Jellyfish are beautiful animals that swim in the water.

Now we're gonna be doing some word problems using jellyfish.

Can you come up with an addition story about jellyfish?

Our friend Anderson came up with a jellyfish story.

Here it's his story.

There were five large jellyfish in the ocean, and three small jellyfish.

How many jelly fish were there in all?

Let's act out Anderson's story on our mat.

Anderson said that there were five large jellyfish.

Let's count them.

One, two, three, four, five.

Then he said there were three small jelly fish in the ocean.

Let's add them to our mat.

One, two, three.

How many jellyfish were in all?

Can you count with me?

Let's do it.

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

There were eight jellyfish swimming in the ocean.

Now we're gonna do that organized quick draw to show our thinking.

There was five jellyfish, one, two, three, four, five.

We're gonna draw our line to separate our numbers.

There were three more small jellyfish.

One, two, three.

There were eight jellyfish in all.

I know that because there was the group of five and three more.

Now let's try to write it as our number sentence.

Five plus three more equals eight.

There were eight jellyfish in the ocean.

Now let's see if we can come up with a subtraction word problem for jellyfish.

Our friend Tenshi was able to come up with the problem.

She said that there were eight jellyfish swimming near the coral, three of those jellyfish left.

Let's show it on our mat.

Here we have our five and our three.

So we know there are eight jellyfish on the coral.

Three of them swam away.

One, two, three.

How many are left?

Can you count with me?

One, two, three, four, five.

Now, let's build our quick draw.

There were eight jellyfish, one, two, three, four, five, six, seven, eight.

Three of those jellyfish swam away.

Remember, we're just gonna cross them out.

One, two, three.

That means there was five left swimming by the coral.

Let's try to write our matching number sentence.

Eight take away three equals five.

You worked so hard on comparing numbers today.

Now, you are gonna get a chance to try some more.

These are called story problem puzzles.

And what you're going to do is you are going to get a story problem and see if you can match the drawing along with the number sentence to go with it.

You have worked so hard today.

We were able to work with our counting buddy friend, and we were able to do some addition and subtraction word problems, and we were able to compare them.

I had so much fun with you and I hope you did too.

And we will see you soon.
