It’s a day that brings math lovers, sweet-toothed pie enthusiasts and pizza fanatics together: National Pi Day. Recently, teacher Kate Lane’s fifth-grade class celebrated the day sweetly.
National Pi Day 2018 — which celebrates the mathematical constant shortened to 3.14 and is, naturally, held every year on March 14 — includes a long list of deals on pizza pies and all different types of sweet pies.
The students learned that Pi is a number, approximately 3.142. It is the circumference of any circle divided by its diameter. The number Pi, denoted by the Greek letter p, is one of the most common constants in all of mathematics.
