8 Ways to Celebrate the Ultimate Pi Day: 3.14.15

Every year on March 14, math and science educators and enthusiasts across the globe celebrate the number that represents the ratio of circumference to diameter of a circle with parties, parades, pie eating and number memorization contests.

But this year, on March 14, 2015 (that’s 3-14-15) fans of this irrational number will get more Pi than ever before…and more than they’ll ever see again in their lifetime. That’s because the next two digits in the Pi sequence after 3.14 are 1, and 5.

After this year, we won’t see this many digits of Pi on our calendar again until the year 2115. Making this year’s Pi day the ultimate Pi day.

If you’re looking for fun and engaging ways to celebrate this once in a lifetime occurrence with your students while teaching them about the mystery and excitement of this special number, look no further.

We’ve gathered some of the most useful resources from around the web where you’ll find classroom activities, fun facts, teaching tools, and entire fan clubs dedicated to honoring Pi in all its forms.
