ABSTRACT

We will look at numerous characterizations of the geometric mean (spanning all five NCTM content areas) and demonstrate some applets, GSP sketches, graphing calculator strategies, and other representations for illuminating these characterizations. Our goal is for our middle school/secondary teacher education students to have a well-connected understanding of geometric mean.
