Things to do this Pi Day
Make (and Eat) a Pie – These pie recipes for Pi Day from NPR’s McCallister look incredibly tasty. But, there’s no shame in putting a frozen store-bought pie in the oven, or picking up a pie from your local bakery. Any kind of pie is great on Pi Day! If you’re making your own, get inspired by these beautifully designed Pi Day Pies. Tell us on Facebook: What’s your favorite kind of pie for Pi Day?
Pi Music – Compose, sing or play a Pi song on Pi Day: Check out this piece for violin, or this Pi song by David Perry on guitar, or this ensemble piece by Michael John Blake with xylophone, piano, accordian, ukulele, banjo and more:
Pi Arts & Crafts – If music isn’t your thing, do an art project. Check out this Pi Day cross-stitch or other Pi Day craft projects. Etsy has all kinds of Pi Day crafts for sale.

Events
Princeton Pi Day Party
Princeton has an annual party celebrating Pi Day and Einstein’s birthday (also March 14). This year, their celebration runs 4 days, from the 11th to the 14th. Tons of math, Einstein (he spent some time at Princeton), and of course pie events and activities. Learn more at: http://www.pidayprinceton.com/events.
Nowhere near Princeton? San Francisco’s Exploratorium, the birthplace of Pi Day, is closed on Monday, but check out their Pi Day activities from last year to plan your own Pi Day party. Seek out your high school or college math club, maker group, science museum, etc. – they almost always have Pi Day parties.
