Master's Project - Algebra

A. O. indicated in her blog that she would like to learn more about Sketchpad and how to use this with algebra.  This is a great idea and one that would be approved.  There are algebraic concepts that she has explored (like slope) but one down side is that slopes are measured in decimals.  Or is that a down side?  GeoGebra will measure the slope (and illustrate it) as a ratio of the sides of a right triangle (which is how I teach slope).  So my point is that just because this is a geometry course, algebra on GSP would be a worthwhile project.
