This is a step in the right direction for math I think.
I would also suggest experimenting with Maxima and Octave.
They are both easy to install. My impression is that Maxima
is a computer algebra system that is similar in some respects
to Mathematica, and Octave is similar to Matlab. Mathematica and
Matlab are two of the primary commerical applications used widely
in math departments at major universities. Even though high
schools (or community colleges) might not be able to afford
site licenses for Mathematica or Matlab, if students have some
experience with Maxima, Octave, they might be much better
prepared for a first encounter with Mathematica or Matlab.
If someone from a major university could verify or expound
on this impression between the similarities between
Mathematica/Maxima Matlab/Octave, that would really be
appreciated. I think I'm correct about this, but I'm
not 100% sure!
