RE: Spherical geometry.
A(n) Hungarian mathematician and teacher developed some materials for teaching
sphericl geometry (plastic sphere, compass, some overlays fit for a projector
as well as curriculum). Key Curriculum Press of Berkeley
brought the things to the US and was working on developing the lessons and
materials further. I haven't seen the finished product but I believe it is
complete and is in their latest catalog. 510-548-2304
