Geometry - Circle Circumference - Intro

Unit 2

This math unit begins by introducing students to the concept of Pi, first as a Greek letter and then as a ratio related to circles. It progresses by teaching fundamental circle properties, starting with calculations involving the diameter and radius of circles before moving into how these dimensions relate to calculating circumference using Pi. The unit gradually incorporates more complex exercises, such as computing circumference with given radius or diameter, first using approximations of Pi and then exact values. As the unit advances, students practice arithmetic operations involving Pi, and skills like using calculators and applying formulas (\(C = \pi \times d\) and \(C = 2\pi r\)) correctly. Near the end, the focus is on reinforcing the relationship between the diameter, radius, and circumference, and applying these concepts practically, encouraging mental math and self-assessment. The unit rounds off by revisiting core concepts, ensuring a solid understanding of circle geometry.
