Online math teachers instruct students in different levels of mathematics, from basic arithmetic to calculus and beyond. While regular math teachers work in a classroom, online math teachers conduct courses through virtual classes and online programs. Online math teachers may provide instruction every day, or they may have a more flexible schedule and teach once or twice a week. But their job duties are very similar to classroom math teachers. Responsibilities include preparing lessons, facilitating the curriculum, assigning and grading homework, and administering exams. Online math teachers also monitor student progress and develop teaching tools to encourage students who are above grade level and provide extra help to students who are falling behind.
