- My love of kites started about 20 years ago.

程度副詞

I just combined the two to try to reach all of my students.

I figured, why not take this whole math lesson outside?

Maybe, just maybe, they would see the relationship.

but in Delray on the beach when I'm flying my kites,

I bought my first kite, and I never looked back.

On any particular given day, you can paint the sky

with sea creatures, whales, scuba divers.

There's math there, and you can do something with it.

Kites are geometric figures, kites are triangles.

Instead of doing it in the classroom at desks,

If we want to use Pythagorean theorem on a beach

and we let the kite go and it travels up the line,

If we draw a line from the top of the kite

back to where we let the kite go, that would be side B.

So by plugging those numbers into the triangle,

we have just figured out how long our string is

from where we are standing to the top of the kite.

We could do fractions, common denominators,

uncommon denominators, the more complicated the numbers are,

We get a lot of families that come on Delray Beach,

\"We can do a math problem with that,\" you know?

And some kids understand, \"Oh yeah, we did that in school.\"
