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."
