[upbeat music] - Hey, friends, I'm Omar.

I'm joining you all the way from Egypt.

I'm here visiting my friends and family.

It's been so nice.

Come on, there's so much I wanna show you here.

[airplane roaring] Egypt is a place far from where I usually live, in New York.

I'm in Cairo.

It's the biggest city in Egypt, and it's where a lot of my friends and family live.

This is them.

And this is my grandma.

We all call Sitho I stay with her when I'm in Egypt.

When we're together, we spend so much time on her balcony.

She tells me stories about the places she's been and about the ways Egypt has changed.

She's helped me see so much of the beauty in Cairo.

Friends, do you have a special place where you sit with a loved one?

What do you talk about there?

Hmm.

Well, on the balcony, Sitho and I like to count the passing cars one by one.

Will you count cars with us?

Awesome!

One, two, three, four.

Nice job counting, friends.

You know, lately I've been seeing shapes in the things around me, like those cars.

When you look at cars, do you see any shapes?

What shapes do you see?

The wheels of the car are definitely circles, and then the body of the car, I see rectangles.

[clock ticking] [bells chiming] I also like to sit on balconies with my friends.

One day when we were on my friend Fifi's balcony, we got two visitors.

Can you see what visitors we got?

[bell chiming] Yeah, we saw two pigeons.

And I see shapes.

I wonder how I can make a pigeon with these shapes.

Okay, definitely a triangle for a beak.

Maybe it's neck is a square.

And for its body, I see some triangles.

What about its tail?

I see a parallelogram.

And another triangle for its foot.

[bells chiming] Friends, I can't stop!

I'm seeing shapes in everything.

And now, I'm starting to see math all around me.

It turns out math was everywhere.

I just had to look for it.

[upbeat music] When I'm not in Sitho's apartment, I like to explore Cairo.

There's so much to see and so much history.

In this same place, where my friends and family live now, many people lived before.

These people built things that have stayed with us, things that remind us of all the people who have shared this one place.

That's what makes old cities like Cairo so special.

They're made up of layers of life over time.

In Egypt, one of the biggest reminders of the people who came before us, people who lived a long, long, long time ago, is the pyramids.

Have you ever built something that looks like that?

Can you see the shapes here?

Yeah, a pyramid is made up of triangles.

And that's not all.

A pyramid is a type of 3D shape.

It has three dimensions.

It fills up space.

So a pyramid is made up of four triangles, and if you lift it up, you'll see that has a square base.

Four triangles and one square, that makes a pyramid.

[upbeat music] - Here are a lot of pyramids in Egypt, including some that you can go inside of.

The pyramid that I went inside of is called the Bent Pyramid.

It's called that because its sides are crooked.

They're not actually triangles, but look at it, it's huge!

[upbeat music continues] I went to the heart of the pyramid where a mummy was once buried.

Getting there was tricky and so was getting out.

To get from the underground mummy's chamber to outside to the star, I had to move my body in lots of ways.

I climbed up the stairs, [footsteps thumping] crouched through the tunnel, [upbeat music continues] and crawled up the ramp, [upbeat music continues] and then I was out of the Bent Pyramid.

And I saw so many shapes on the way there.

Friends, do you see them?

Yes, rectangles!

Rectangles everywhere!

I had so much fun at the pyramids that I wanted to keep exploring.

I set out to learn more about ancient Egyptian history, about how people could build something so impressive.

I visited the National Civilization Museum with my friend, Mohais.

The museum shows the layers of life over time, the pieces of history that are still with us.

Old chairs, tools, coins.

And I saw shapes everywhere!

Friends, will you tell me what shapes you see?

This checkered material is leather.

It's part of a tent made by ancient Egyptians.

What shapes do you see here?

[gentle upbeat music] Yeah, squares.

Lots of squares.

Okay, how about here?

What shapes do you see on this wall of an old building?

[gentle upbeat music continues] Triangles, lots of them!

And circles all over!

This wall was covered with shapes.

Then Mohais and I went to the Royal Jewelry Museum.

It's a museum full of the jewels, the bracelets, rings, necklaces, that were once worn by the people who used to rule Egypt.

It's really beautiful.

There were lots of shapes there too.

Help me find them.

[gentle upbeat music continues] This is the wall of one of the rooms.

Every detail was decorated.

What shapes do you see?

[gentle upbeat music continues] Yes, a square, and above it, a rectangle.

Ooh, and another rectangle on the outside.

Rectangles inside of rectangles.

Elsewhere in the museum, I kept noticing the wood floors.

They were filled with details.

What shapes do you see here?

[gentle upbeat music continues] Yeah, circles with squares inside.

[gentle upbeat music continues] Friends, you're getting really good at spotting shapes.

Isn't it cool how once you start seeing shapes somewhere, you start seeing them everywhere?

Okay, there's one more place that I visited that I wanna show you.

It's the Muhammad Ali Palace.

This palace used to be somebody's house.

There are lots of shapes here, including some pretty complicated ones.

Let's see if we can find 'em.

In this colorful room, the ceiling is lined with trim made from small pieces of wood stuck together.

What shapes do you see?

[gentle upbeat music continues] Squares?

Yes.

And look at those light blue shapes.

They almost look like houses.

Those are pentagons.

I know they're pentagons because they have five sides.

Ooh, and what about those red shapes above them?

What shape is that?

Let's count the sides to find out.

One, two, three, four, five, Six.

Those are hexagons.

[gentle upbeat music continues] Okay, let's look at another room in the palace.

Wow, look at those colorful stained glass windows!

What shapes do you see in the windows?

[gentle upbeat music continues] Yes, some squares and rectangles.

That's right.

What about those other shapes?

The ones that zigzag?

Let's count the sides to find out.

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

Eight sides.

Those shapes, they're octagons.

Thanks for finding those shapes with me and for joining me on this journey through Egypt.

Seeing the shapes around me helped me see Egypt and its history in a new way.

It was like I was seeing with math glasses.

Friends, what math do you spot around you in the room that you're in right now?

Do you see any shapes?

What about in a place you really like, like a park or a playground or a classroom, what math do you see there?

Next time you're out in the world, next time you're out anywhere, remember that math is all around you.

Go out and see what math you can find today.

Bye.
