Semester Project

Because my district is in program improvement, there has been a huge push to do things "one standard at a time."  Not a bad idea since the standards (for algebra anyway) are pretty solid.  The problem lies in the fact that there is a tendency to simply teach the skills and neglect the conceptual development as well as problem solving aspect to algebra.  So I decided to call a buddy of mine who happens to be a farmer and here is a project I came up with.  I created an answer key using GeoGebra that allows for quick checking of student progress.  Feedback request: I would really like some input on this one.  I know that I would like to use it again next year, but I know it needs some work.
