Sorry I didn't get back to you, I have been away. The two classes were at the back of the gym. They took up about half of it. When you came in the front door there was a long hall leading to the gym, the classrooms were on each side of the hall. They were there as long as I was. The science room in the basement was in the front under or near the main entrance. That didn't last too long cause the animals stunk! We also had animals in our grade 7 class ( Mr. McMenamy) but you just cant keep a beaver in a wood cage!!!!!!
