This is the second lesson of a 2-day mini-unit on the Golden Mean. The first lesson introduced students to the myth of Daedalus and Icarus. This lesson can be condensed by removing the section connecting the myth to the Golden Mean. This download comprises a detailed lesson plan with the objective, minute by minute breakdown and anticipated student misunderstandings, in addition to the classwork itself. Note: Due to copyright issues, the download does not include the text explaining Aristotle's Golden Mean. However, this can readily be obtained online for free.
