Did your school accredit you to teach math? You need to have a certain number of math credits, I believe 15 to be able to teach math, otherwise your school is in violation of the schools
accreditation committee regulations.
If you do have to teach math, do not stress too much about it, you will do great, it is just like any other class. Prepare for your class ahead of time, and if it is a one hour class, I would take the first 5 minutes to take the attendance, answer questions. The next 15 minutes to lecture based on the lesson, 5-10 minutes to solve a basic exercise pertaining to the lecture on the board, and the rest of the time I would have students solve certain exercises, and I would just walk around and review what they did as soon as they are done. You might end up liking to teach math
, I really think it is fun and easy. Good-luck!!!
