Pros
Mathnasium was one of the most rewarding positions I've had. I loved working with the students and witnessing their improvement. Prior to teaching at Mathnasium, I worked in an office and-- although the math is simple-- it's great to have a position in which you can actually use your brain and math skills. Fellow employees, the center director, and the owner were all wonderful. There were only one or two issues with parents, but that's expected in any work environment.
Cons
The pay was really low; I wouldn't have been able to get by on my Mathnasium wage alone. The hours revolve around school hours, so the business is only open a few hours each day, which doesn't provide a sufficient opportunity to work longer to compensate for the low wage.
