# What Is Pi Day?

## Worksheet Description

This Pi Day worksheet is designed to educate and engage students with the fascinating world of mathematics, specifically focusing on the enigmatic number π (pi). The worksheet features a brief and intriguing exposition on pi, explaining its significance and ubiquity in a range of contexts, from the theoretical circles of mathematics to everyday objects and activities. Students are prompted to consider pi not just as a number but as a concept that ties together geometry, architecture, and technology. It outlines pi as more than just 3.14, delving into its nature as an irrational number that continues infinitely without repeating, making it a topic of endless exploration and curiosity.

The second part of the text brings the concept of pi closer to the students’ experience by relating it to the circumference of a pizza and the calculations involved in everyday architecture and technology. It illustrates how pi is integral to understanding shapes and forms in both the natural and constructed world, and how it plays a critical role in algorithms that power computers. The aim is to show students that pi is not just a mathematical constant but a foundational element in various fields, underpinning the very structures and systems that make up our world. This worksheet serves as an accessible introduction to a complex mathematical constant, sparking interest and appreciation for pi and its applications.
