You might find this page
http://www.python.org/community/sigs/current/edu-sig/
and the education list itself. I am sure many programs useful in 
education have already been ported.

Many simple programs, of the sort used in beginner classes need minimal 
change. Oftem 'print x' to 'print(x)' is all that is needed. 2to3 will 
do that for you, once you learn how to use it, but I have not.  For the 
programs people post on the list, with just 1 or 2 prints, I make the 
change manually in the Idle editor before running. I often want to 
change other things as well, so no big deal.
