  • - My love of kites started about 20 years ago.

  • I taught math for 35 years.

  • 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.

  • - My name is Winfred Randolph Lowe,

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

  • they call me Randy The Kite Man.

  • (upbeat music)

  • I started flying kites 20 years ago.

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

  • I fly my kites as much as possible.

  • I have about 60 or 70 kites.

  • On any particular given day, you can paint the sky

  • with sea creatures, whales, scuba divers.

  • You're not only looking at the kite,

  • but you're looking at the strings.

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

  • Kites are geometric figures, kites are triangles.

  • And that is one of the things

  • that I tried to take advantage of.

  • Instead of doing it in the classroom at desks,

  • we take them out in the field.

  • Pythagorean theorem is a formula used

  • to determine sides of triangles.

  • If we want to use Pythagorean theorem on a beach

  • as we're trying to fly a kite,

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

  • better known as the hypotenuse.

  • If we draw a line from the top of the kite

  • down to the bottom, that's side A.

  • If we draw another line from that point,

  • 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.

  • There's your answer.

  • We could do fractions, common denominators,

  • uncommon denominators, the more complicated the numbers are,

  • the more math there is.

  • I retired six years ago.

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

  • and they have kids, and I teach math.

  • I tell them, \"See that right there?

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

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

  • Nowadays, they see it.

  • But for a lot of the younger kids,

  • it gets them thinking, too.
