I do! We used them from grade 2-4. I've played all the ones you mentioned above except for Math Ville. Sadly the only game that seems even remotely playable right now is Crosscountry Canada. It's decent, but I'd love someone to dig up the whole catalogue some day.
Some games I extremely remember are New Kid in Town, Northwest Fur Trader and ChemistryLand. I have blurry memories of a school-themed game called Academy.
One of my all time fave games on the ICON was The Bartlett Saga. Was a multi-part history game following a family of refugees. The best one is probably Refugees in the Wilderness. Kind of like Canadian Oregon Trail but less of a journey and more vignettes/mini-games. Someone seems to have translated odd bits of it to the browser (boo flash) here: http://www.theloyalistbartletts.com
IPaint was a great drawing/animation program in that a 7-year-old can make fully-animated stories in 15 minutes. That's a feat.
LOGO was also an interesting thing. You would issue commands to a triangle called a "turtle" and it would walk out those commands and create shapes out of the path. Apparently a real programming language for a real robot called a turtle.
Anyway, I miss that old girl.
