## Overview:

On March 14, schools celebrate Pi Day (Greek letter “π”), the symbol used in mathematics to represent a constant—the ratio of the circumference of a circle to its diameter.

Every year on March 14, schools celebrate Pi Day (Greek letter “π”), 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 Day is an annual opportunity for math enthusiasts to recite the infinite digits of Pi, talk to their friends about math, and eat pie.

Pi has been calculated to be over 50 trillion digits beyond its decimal point.

Pi will continue infinitely without repetition or pattern as an irrational and transcendental number. While only a handful of digits are needed for typical calculations, pi’s infinite nature makes it a fun challenge to memorize and computationally calculate more and more digits.

Here’s a list of 10 books perfect for celebrating Pi Day with students:
