Math Geeks, Are You Excited for Pi Day?

This post may contain affiliate links.

I’m not really a math geek, nor do I play one on t.v., but I’m excited for Pi Day! (Aren’t you?)

Pi Day is March 14 and it’s also Albert Einstein’s birthday.

(Which I’m sure you already celebrate.)

For some of us, it’s been awhile since geometry so here’s a quick refresher:

  • Pi is 3.14159 . . . (See the connection to March 14th now?)
  • Pi is the number you get when you divide the circumference of a circle by it’s diameter.
  • Pi is infinite.
  • Mathematicians at the University of Tokyo used computers to calculate pi to 1,241,100,000,000 decimal places – which is the world record.
  • Pi is also written as a symbol: π .

3.14 Ways to Celebrate Pi Day With Kids

1. View the first million digits of Pi on the Pi Day website — it takes some time to read but I’m sure you can do it. 🙂

2. Read books about pi. Sir Cumference and the Dragon of Pi, Why Pi?, and The Book of Perfectly Perilous Math

3. Make a pi paper chain or necklace. Give each digit a color. Then, using paper strips, create a pi chain. Or use beads and make a necklace in the same color-coded way.

0.10 Do a jar lid exploration of pi. Get a variety of jar lids, scissors, string, rulers, calculators. Work in pairs or groups with one jar lid. Use the string to measure the circumference of your lid (wrap around, then use the ruler to measure.) Use the ruler to measure the diameter of your lid. How many diameters get you to your circumference? Discuss. Great post on this activity on Geek Mom.

0.04 Wear Pi Gear.

Make your own pi hat.

Buy pi shirts on EtsyThink Geek, This Next (below “Mu-tant Cow Pi,”) Cafe Press, or Mental Floss.
