Projects to Celebrate Pi Day

Pi Day is March 14.

Well, if you want to get nerdy about it, it’s March 14 at 1:59 and 26 seconds, and you know I ALWAYS want to get nerdy!

But for the purpose of celebrating the universal constant that is the ratio of a circle’s circumference to its diameter, let’s just go with March 14 as a whole. That way we get to celebrate all day!

Days like Pi Day (and Star Wars Day, which comes a couple of months later, and the anniversary of the Battle of Hogwarts, also in May), are fun ways to add a little splash of festivity into what would otherwise be a normal day. It doesn’t take a national holiday and a giant feast in order to raise your wands in memory of the fallen on May 2, and you don’t have to spend the entire day at the mall with your extended family on May 4–instead, you get to have a Star Wars marathon!

And the same goes for Pi Day. Don’t be afraid of math–celebrate it! Bake a pie, order a pizza, and check out some of the other super fun projects that you can do to get a little more festive on this most Circular of Days.

I'm a writer, crafter, Zombie Preparedness Planner, and homeschooling momma of two kids who will hopefully someday transition into using their genius for good, not the evil machinations and mess-making in which they currently indulge. I'm interested in recycling and nature crafts, food security, STEM education, and the DIY lifestyle, however it's manifested--making myself some underwear out of T-shirts? Done it. Teaching myself guitar? Doing it right now.

Visit my blog Craft Knife for a peek at our very weird handmade homeschool life, and my etsy shop Pumpkin+Bear for a truly odd number of rainbow-themed beeswax pretties.

  1. I liked your article because Pi Day should be about Making Math Memorable with hands-on activities.

    Last Pi Day The New York Times’s NUMBERPLAY Column and the National Science Teachers Association posted the ‘Sneaky Pi Detector’ on their Resources for Teachers page and the Great Lake Science Center included it for their celebration:
