# Three Common Equations

## Worksheet Description

This Pi Day worksheet is centered on the mathematical constant pi (π), offering students an opportunity to explore its significance and applications. Students are prompted to write their names at the top, personalizing the educational experience. The title “The Number Pi” is followed by five questions designed to deepen the student’s understanding of pi, its characteristics, and its use in mathematical formulas.

The questions begin by asking students to define what the number pi represents, encouraging them to connect the concept with its geometric significance. Further questions prompt students to write the commonly used approximation of pi, inquire about the extent of its decimal expansion, explore why pi is classified as an irrational number, and list common equations that utilize pi. By answering these questions, students engage with the fundamental properties of pi and recognize its pervasive role in mathematics. This worksheet provides a focused exercise for Pi Day, ideal for math classes seeking to commemorate the day with content that reinforces key mathematical concepts. It serves both as a test of existing knowledge and as a catalyst for further inquiry and discussion.
