www.m-a-t-h-s.org is a website that intends to compare the teaching of mathematics  in France (until the  baccalaureate) and Switzerland (until maturity).

You will find here, for each 'classroom', a description of academic programs, resources for understanding and practice, picture and videos galleries, links and a few other things.
This site is still very young, the author completes it regularly and you can get an idea of his progress by viewing the summary (in french - click image):
