A mathematics teacher in Tunisian public schools. I have been practicing this profession for 3 years, during which I was able to identify most of the difficulties that students face in this subject and how to simplify the information so that they can understand it. How I work: First: an assessment test to determine the student’s level Second: Providing an explanation of the lesson that is consistent with the student’s level Third: Applying the lesson rules in the form of exercises in an ascending order (from direct application so that the student can master the rule to more difficult exercises to improve his level). Fourth: Written test Finally, the most important thing for me is to know the student’s weak points and work together to improve them, to know his weak points, and to work on further damaging them.
