We have a lot of underfunded school. The particular school I am talking about is next to a train track and a metal foundry (everything was covered with yellow dust and there was smog all over) and uses a parking space as a recreation area (hey, you can play hockey on it during winter...). In 2009, one of the wall/window fell during winter and the kids had to wear their coats indoor for a month, since plastic garbage bags and duct tape was all that was covering the hole.

As for what happened to the math teacher in question, I believe that she had left the school because she had to teach multiple groups (can't remember how many groups, but it was without a doubt too many) that were too bigs and filled with kids that shouldn't have been there in the first place. Learning disabilities, violent teens, etc. all crammed in a small room, groups of... I think it was 35 students.

Note that the stat I pulled out is from a school board in Montreal.
