The math class representative is the assistant of the math teacher, who is responsible for sending and receiving math homework, marking papers, grading and so on. The representative of math class is the person who has the closest relationship with the math teacher among the students, and has more opportunities to communicate and discuss with the teacher. He is under the jurisdiction of several group leaders. When the teacher is absent or studying by himself, he also acts as a temporary inspector or lecturer. First, the role of a good math class representative in the completion of homework after class 1. A good example for students. Be sure to sit up straight in class, don't raise your hand and don't interrupt casually. In addition, math class represents the quality of homework and will set an example for others. 2. The bond that conveys the feelings of teachers and students. Some math teachers are not class teachers, so they have relatively little time to communicate with students, and once the knowledge points are difficult to master, the students' reaction will be more intense. At this time, the math class representative should promptly reflect to the teacher the questions that everyone can't do and the knowledge points that they don't understand, and reflect the confusion of the students to the teacher. Knowledge points are understood, students' grades are improved, and the feelings between teachers and students are naturally good. 3. The teacher's good helper. In mathematics teaching in primary and secondary schools, from the statistics of wrong questions in daily knowledge points to the analysis of difficult problems, it is inseparable from the figure of mathematics class representatives. Especially for all kinds of quizzes, teachers simply don't have time to judge scores and count error rates, so math class representatives will be useful. Also, after the group marking every day, the class representative organizes the grading in time and acts as a good helper for the teacher.
