March 14 is Pi Day and Albert Einstein’s birthday! How are you going to celebrate?

Pi (Greek letter “π”) is the symbol used in mathematics to represent the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

Around the world, people celebrate the universal language of math by recognizing Pi Day.

Have a Pi memorization contest (winner gets a piece of pie!)

Have an Einstein look a like contest.

Cut Pi (Wrap a string around the circumference of a circular object. Cut the string when it is exactly the same length as the circumference. Now take your “string circumference” and stretch it across the diameter of your circular object. Cut as many “string diameters” from your “string circumference” as you can. What do you notice?

Create a daisy chain of circles to encircle your classroom with trivia, facts, history, and information about pi created by students.

Top Five At-Home Activities

Surround yourself with Einstein quotes

Watch a video about Archimedes of Syracuse (287–212 BC) or one of the other mathematician’s who helped us learn more about Pi.

Create an Infographic about the various fields of mathematics and science that Pi is valued (geometry, trigonometry, calculus, cosmology, number theory, statistics, fractals, thermodynamics,mechanics, electromagnetism, engineering, computer algorithms, etc).

Pi has been calculated to over one trillion digits beyond its decimal point.

Pi is irrational and transcendental number.

Pi will continue infinitely without repetition or pattern.

Hold Pi (3.14) up to a mirror and it spells PI.E

Pi has been known for almost 4000 years
