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.

Learning Bridge Middle School found a big reason to celebrate this year too. Our math enthusiasts called the 14th of March, “Rounded Pi Day.”

When rounding pi to the ten-thousandth (that’s four numbers past the decimal point), it comes out to 3.1416, matching Pi Day date — March 14, 2016.

And if you need any more reason to get excited about March 14, here’s one: it was Albert Einstein’s 137th birthday.

Pictured above is Mrs. Jamie Lawrence, 6th grade teacher at Learning Bridge Charter School. Mrs. Lawrence is conducting a math read aloud to her 6th grade students before they began their day of celebrating Pi Day 2016.

They conducted several hands on activities that helped each student better understand this math concept.

The middle school finished the day by indulging in Pie donated by parents, and teachers.
