**Session Author: **Tom Davis

Many topics in mathematics can be made much clearer when symmetric aspects are made clear or when nice alternative visualizations are possible. When this occurs, it helps both the student and the teacher. We will examine visualization and symmetry in a very general way by means of a set of problems.

There is a large amount of potential classroom material here, and almost any small part of it could be used for an entire class session.
