# The Emerson School Pi Day (March 14th)

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

Activities will include:

1 – Discovering Pi (10 minutes)

Activity 2 – Constructing a Circular Necklace

Activity 3 – The Expanding Circle

Activity 4 – Pi Memorization Contest

Activity 5 – Equation of a Circle Activity

Activity 6 – Concentric Circles (Bullseye)

Expanding Circle Demonstration

Pi in the Face

There will be awards, prizes, etc.
