I am looking for someone who has rewritten some of the Geometry Sketchpad worksheets that come with the teacher package so that especially younger students (say grade 9 and grade 10) have more structure for theiranswers. Asking for their "conjectures" and giving them a series of blank lines is too vague. The worksheets are generally well done but it is still unclear which sheets to start with. With all technology it seems better to face the idea that at first you're learning the medium itself and the math is secondary to that. (Hence, Dr. Lopez' recent book called MAPLE WITH CALCULUS which is supposed to be a calulus book but understands its prior purpose.) So, I don't think the answer to where to start with GSP is terribly connected to what topic you happen to be on in your math class. I started my grade tens with one of the rhombus constructions: not too bright! It is too hard to choose the correct intersection points on the circles. Then I tried the trinagle incenter construction, followed the next day by the triangle circumcenter construction. This worked OK except I was run off my feet getting everyone up to speed, and drawing conclusions was tough as simply those rotten "conjectures."
