Two 10-year-old boys figure out the meaning of pi, the never-ending number that starts with 3.14, and then celebrate with pie and pizza pie on National Pi Day, March 14 (3/14).
Pie, Pizza Pie, and Pi -- National Pi Day
MAURA SIMONS: So, Happy Pi Day.
NATALIE MORALES, reporting:
It’s Pi Day in Mrs. Simons’ fourth grade class. No, not that kind of pie, and not this kind of pie either.
SIMONS: We’re going to talk about the mathematical pi, which is this symbol, which is spelled P-I. And it represents 3.14.
KANAN: How about we just trace that first, okay, Zach?
MORALES: Zach and Kanan are on a mission to find the circumference of a circle.
ZACH: So it would be five with the remainder of 3.5. It’s weird.
KANAN: I know. Can we-- we can ask Ms. Simons for help?
ZACH: No, let’s just try to do this to ourselves.
MORALES: Ten-year-old Zach has always been an eager problem solver.
WOMAN: What number is that?
MORALES: In kindergarten, Zach showed an aptitude for math beyond his years. And his curiosity about science led to backyard experiments with his dad.
DEBORA (Zach’s Mother): He can take something that he’s seen in a book or that he’s conceptualized in his mind and he can apply it to everyday activities.
ZACH: Well, a radius is half of the circle, a diameter is a full circle.
MORALES: Thanks to Zach’s love of math and science, the concepts of geometry are as easy as pie.
SIMONS: He has an excellent math mind. He’s very logical.
KANAN: It’s kind of like the same, but not barely.
MORALES: For ten-year-old Kanan, solving a math problem is usually easy. Talking about his solution is the hard part.
SIMONS: He is more shy and reserved. But he’s really come out of his shell this year.
KANAN: Mental math is-- is math by doing it in your head.
JOANNE (Kanan’s Mother): All right.
MORALES: Kanan’s mom says Kanan’s confidence in the classroom is translating to more communication at school and at home.
JOANNE: He’s actually becoming more verbal with me where he talks about his feelings and things that are happening in school, which-- it’s-- it’s really nice.
KANAN: Wait, Zach, Zach, Zach it’s not equal yet.
MORALES: Kanan has been classmates with Zach for four of their five years in elementary school. Along with his growing confidence, Kanan’s comfort level with Zach makes him a good math partner.
ZACH: You want to do it this time?
KANAN: Let me do it.
SIMONS: There is a mutual respect there. You know, Zach would res-- was respecting Kanan’s opinion and Kanan felt comfortable enough with Zach to be able to say I disagree.
ZACH: The diameter is one hundred eighty.
MORALES: Zach and Kanan test their answers on the playground.
SIMONS: You found it excellent.
MORALES: And now it’s time for pie.
KANAN: I like cheese. This is good.
MORALES: This kind of pie and that kind of pi.
SIMONS: We’re having the P-I-E because of the P-I.
Math and Statistics
Have your students find examples of where Pi can be found in school or at home. Then, make a "Where is Pi" video showing all of the places the students found Pi.
