[bright music] - Hello, my name is Mrs. Tahese and today I'm going to do a really fun math activity with you that involves fractions and uses our five senses.

Before we talk about what fractions are, let's talk about our five senses.

Now our five senses include our sense of sight, we use our eyes to see things around us.

Our sense of smell, we use our nose to smell things.

Our sense of hearing, we use our ears to listen out for things.

Our sense of touch, we use our fingers and our hands to feel things.

And last but not least, our sense of taste.

We use our tongue and mouth to taste things.

And today we are going to use our sense of taste.

Now, what is a fraction?

A fraction is a number that represents parts of a whole.

These parts are equal parts that when combined together make up the whole.

A fraction is made up of two parts.

So, here you can see I've written a fraction.

This is how you write a fraction, one number over top of another.

This number is actually represents one half of a whole.

The top number is our numerator and our bottom number is our denominator.

For today's activity, we are going to use graham crackers.

So we are gonna get a chance to taste them, but after we learn more about fractions.

I wanna introduce you to my friend.

- Lily.

- Hi, Lily, thank you for joining me today.

We're both gonna get a plate.

And Lily's so lucky because she has a graham cracker and I have nothing.

- That's not fair.

- It's not fair, it's not.

So, Lily, we're gonna play a game where we're gonna share the graham cracker.

- We're gonna be nice.

- Yes.

And we're gonna use fractions to share the cracker.

So, Lily, let's talk about what you have on your plate.

What fraction, what would you say your graham cracker is?

Is it a whole, a half, or a quarter?

- [Lily] A whole.

- It is a whole, right, because it's still all together.

Now, Lily, let's see, can you give me half of your graham cracker?

Could you put half of your graham cracker on my plate?

- [Lily] I'll try to make it even.

Yay, I made it even.

- All right, so let's hold up our pieces, so Lily gave me a half of her graham cracker, and if we would've put it back together, we would get a whole, right.

So we both, I think we both have equal size.

Is it equal?

- Well, almost, because it's not perfect.

- Not perfect, but technically if it's in half it would be equal, right.

- Not perfectly equal.

- All right, but it's close.

So do you think it's fair?

Do we pretty much have the same amount of graham cracker?

- Yes.

- Great.

All right, Lily, let's continue.

Lily, you know what, I'm really hungry.

How many quarters do you have left on your graham cracker?

- Four.

- Four?

We had four, right, when we had the whole, but right now you have half of it.

So how many quarters do you have right now?

How many pieces do you have right now?

- Two.

- Two.

So, Lily, I'm gonna ask you to give me, she has two quarters left or two pieces from the four.

Can you give me one of your quarters?

- Well, it's not fair now.

- Oh no, why is it not fair, how much do you have?

- One quarter.

- She has one quarter or one fourth, right?

So one quarter or one fourth, the one over four.

And I have, I'm gonna break them apart to make it a little easier.

I have three fourths or three quarters.

So who has more?

- You.

- I do, oh, but that's not fair.

Oh, Lily, you know what?

I'm really, really hungry, can I please have another quarter?

- No.

- Please share, please, please, please, please.

- But then I'll have zero left.

- Well go ahead, put it on my plate.

- No fair.

- So now I have four quarters.

Or if I was to put it all back together, how much would I have?

If I put them all back together?

If I could glue them back together, what would I have?

- A whole.

- A whole, right.

So if I put all four together, I would have a whole.

But you know what, Lily's, right, it's not fair.

So I wanna give her some back.

How much do you want back to make it fair?

- Two quarters.

- Two quarters, wonderful, because I have four.

So if I have four quarters, one, two, three, four, I'm going to give her two quarters.

So you wanna take two quarters off my plate?

One, two, excellent.

So now we both have two quarters, or one half.

She has one half, I have one half.

- And we both have the ones that connect.

- And we have the ones that connect.

You know what, Lily?

I was thinking, I'm actually not that hungry.

So in this case, even though it's fair that we have equal, I would like to give you more of my graham crackers.

How much more would you want?

- Well, I would have one more for you to have one.

- Okay, I'm gonna give her one more, one quarter or one over four.

And now how many quarters do you have?

- Three.

- Three quarters, so she has three over four.

She has three of the four pieces.

And I have one of the four pieces.

- Well, it is kind of fair 'cause you let me have it.

- I did, I gave it to her so it's fair.

So you know what, Lily, I think I'm just gonna give you my last quarter.

Go ahead, take it.

And now what do you have, how many quarters do you have?

- Four.

- Four quarters, Which makes a?

- Whole.

- A whole.

She has the whole graham cracker, and you know, Lily, I think it's time to use that last sense, which is taste.

You wanna taste it?

- Yeah.

- Go ahead.

- Mm.

- Mm.

Okay, so Lily, Lily's tasting the graham cracker.

What does it taste like?

- Graham cracker.

- It tastes a graham cracker.

Does it taste sweet, sour?

- It tastes good.

- It tastes good.

Can you describe a little bit more, sweet, sour?

- It's like sweet.

- Sweet.

- Is it crunchy, is it soft?

- Crunchy.

- Crunchy.

All right.

So, Lily, you did an awesome job today.

I hope you enjoy your graham crackers and- - Can anybody hear me crunching?

- I don't know, I can hear her crunching so I'm using my hearing, right.

So in our last activity, we used our taste, which is what she's doing now.

We used our hearing because we had to speak to each other and listen.

And I also can hear her crunching away.

We used our touch to touch the graham crackers and we used our sight, right, to look at our graham crackers and move them from plate to plate.

We kind of used our smell, 'cause we could smell it as we were working on it.

But usually when we use our five senses, we don't always use all five, but a lot of times we use more than one, okay?

And today we learned about fractions, we learned about the whole, our half, which is two equal parts, our quarters or fourths, which means four equal parts.

And when we put four equal parts together, they make a whole.

When we put two of the fours together, we get a half.

All right, so, Lily, great job.

I hope you guys enjoyed this activity and I hope you try it at home.

You could try it with graham crackers, you could try it with oranges, you could try it with pizza.

- Marshmallow.

- Or marshmallows, right.

So thank you for joining us and we'll see you next time.

Ready?

Bye.

- Bye.
