A math tutor should guide the student through the solution process, not just show them how it's done. Ask the student main questions that lead him or her to discover the right steps. Avoid causing problems for the student. As a math tutor, you should stay positive and continue to support and encourage your students during the learning process.
While not required, consider earning an associate's degree or bachelor's degree in education or in a mathematical field such as statistics or economics. Careers related to that of a math tutor include high school teachers, instructional coordinators, and librarians. It is highly preferable that math tutors understand a level of mathematics that is at least one level higher than the level they are teaching.
