Lesson Plan: Areas and Circumferences of Circles Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the area and the circumference of a circle given its radius or diameter and how to relate both the area and circumference to solve various problems.

Objectives

Students will be able to

  • find the circumference of a circle given its radius or diameter, or vice versa,
  • find the area of a circle given its radius, diameter, or circumference, or vice versa,
  • find the areas and circumferences of shapes constructed using circles, semicircles, or quarter circles,
  • solve real-life problems involving the areas and circumferences of circles.

Prerequisites

Students should already be familiar with

  • what a circle is and identifying its radius and diameter,
  • real numbers and operations on them.

Exclusions

Students will not cover

  • 3D shapes.
