Celebrate Pi Day and earn a slice of the Pi(e) Day patch series!
Do you like pie? Of course! Just about everyone likes pie, but what about pi—the amazing mathematical number?! Well, here at Girl Scouts, we LOVE pi, and we’re gearing up for Pi Day on March 14!
Celebrate any way you choose this year and earn the next patch in the Pi(e) Day patch series! After participating in a Pi Day activity, purchase your patch at any GSOSW Shop.
What is the Pi(e) Day patch series?
Earn your Pi(e) Day patch series by celebrating Pi Day each year. You’ll earn a different slice of pie to wear on the back of your uniform—eventually, you’ll complete your very own pie!
Each year you participate in any Pi Day celebration or activity, you can earn a Pi(e) Day series patch! These activities include attending a service unit or council event, doing something at school, hosting a celebration with your troop, or even having a piece of pie at home with friends or family.
NOTE: This patch program started in 2024. In 2025, the second and first patch designs will be available. In 2026, the third, second, and first designs will be available, and so on, until all eight patches have been released.
Host a Pi Day Event
Host your own Pi Day event with the Pi Day Event Resource—designed for troop leaders, service unit members, and other adults or older Girl Scouts interested in hosting an event for Pi Day!
Contact your service unit GEM (or, if your service unit does not have a GEM, contact answers@girlscoutsosw.org) if you have questions or need help hosting your Pi Day Event!
Pi Day Celebration Challenge
Can’t attend a Pi Day event or host your own event? Then, take on the Pi Day Celebration Challenge!
Complete a series of short activities relating to the amazing number pi with simple supplies you most likely already have at home. After you complete six of the seven Pi Day Celebration Challenge activities, purchase your patch at any GSOSW shop.
