Pi Day is celebrated on the 14th of March (3.14) around the world. Now it is also the International Mathematics Day. Since Pi is the iconic number of mathematics, there are plenty of websites & blogs and zillions of activities out there to celebrate this day.
Throughout the years, I have searched and collected the best activities to share with my students. At the school,
our star activity is selling pi-donuts to donate the money to Nesin Math village in our country.
