Thomas Hodges 

October 2007, Volume 101, Issue 3, Page 205

Abstract:
This article describes an alternate way to utilize a circular model to represent thirds by incorporating areas of circular segments, trigonometric functions, and geometric transformations. Students start activity with pencil and paper, but eventually verify solutions using technology. This task provides opportunities for higher levels of thinking.
