(upbeat music) - Good morning, mathematicians.

Well, it's a rainy day today, and Hallie and Harper, you all are getting a little bored, aren't you?

Well, I thought it would be fun to send them out on a scavenger hunt.

Girls, how does that sound?

Sound like fun?

- Good.

- Yes?

Okay, awesome.

So I have an idea that will make this game about learning too.

I want you to look for examples of parallel and perpendicular lines.

Maybe we should review those words before we get started.

Okay.

So parallel lines are always equidistant, and perpendicular lines meet at right angles.

Okay, girls, so you use your arms and show me parallel lines.

Great job.

Perpendicular lines.

You've got it.

Okay, let's start the scavenger hunt.

Are you ready?

Set, go.

(upbeat music) - Woo, I'm tired just watching you all.

Okay, you found some really great things.

Harper, you found the first aid kit, right?

So when you look at this do you see parallel or perpendicular lines?

- Mm, I see both.

- Oh, I feel like right here, where they cross, that could be perpendicular, right?

I see a right angle.

But also maybe at the top and the bottom, are they running parallel to each other, and then on the sides, they're running parallel to each other?

Great find.

Hallie, did you bring the kite?

- Yes.

- Okay, what do you see when you look at this kite?

- I see perpendicular lines.

- Oh, great job.

Yep, the frame of the kite meets and makes right angles.

So really good.

Who found the shirt?

Harper, when you look at this shirt, do you see parallel lines or perpendicular lines?

- Um, parallel.

- Yes, so those stripes are lines that run equidistant to each other.

And then who found the blocks over here?

- Me.

- Hallie, what do you see when you look at these blocks?

- They're parallel.

- Yes, these definitely run parallel.

They're equidistant from each other.

Okay, you all found some really good things.

Harper, I'm going to challenge you to find one more item.

Do you think you can do it?

- I think I can do it.

- I think you can too.

Ready, set, go.

(upbeat music) - Here you go.

- Great job, good job.

Okay, so you found a picture frame.

When you look at this do you see parallel or perpendicular lines?

- Mm, I see both.

- I agree.

It's kind of like on the first aid kit where you saw both.

So we have parallel lines at the top and the bottom, and we have parallel lines on the sides, but then in the corner, perpendicular, right?

They meet to make that right angle.

That was a really good job.

Okay, girls, I'm so proud of you.

You did great.

I also want to say I appreciate your positive attitude trying to make the best out of a rainy day, yeah?

Mathematicians, I hope you have a great day too.

Try to spend some time today on your own scavenger hunt.

Look for parallel and perpendicular lines and we will see you next time on "Rise and Shine."
