In mathematics learning, students often make mistakes, such as miscalculation, plagiarism, omission, confusion, thinking deviation and so on. And the simpler it is, the easier it is to make mistakes. When there is no reason to make a mistake, it can only be explained by carelessness. How to correct these mistakes, how to make students carefully examine questions and solve problems independently from time to time, correct mistakes immediately when they are found, practice the habit of summing up problem-solving methods, and accurately apply what they have learned in life anytime and anywhere? It seems that it is very necessary to cultivate the level of mathematical error correction of primary school students.

1. Teachers can change the way of correcting homework, turn mistakes into valuable teaching resources, and do a good job in correcting students' homework, thus strengthening teaching effect, guiding students to learn thinking methods accurately, and further improving teaching quality.

2. Establish an error correction book, requiring students to correct mistakes in their daily study immediately. On the one hand, correct mistakes, on the other hand, pay attention to summary and further strengthen.

Calculation methods, classification of exercises, so as to master the knowledge learned.

3. Reasonable arrangement of homework is the first prerequisite for homework modification.

(1) The workload should be appropriate. Reducing students' homework and liberating students, teachers themselves transfer too much time to correcting and commenting, and to preparing lessons carefully and designing homework for students.

Teachers should follow the principle of "teaching students according to their aptitude" when assigning homework. Teaching principles require educators to understand students deeply, study students, be familiar with the characteristics of each student, and conduct targeted education.

③ Homework should be targeted. The arrangement of homework should pay attention to the level of homework, with certain flexibility, aiming at different situations.

Design different exercises to arouse the enthusiasm of students at all levels.

4. Students' autonomous learning is an important way of learning. In teaching or examination, students often make various types of "mistakes", and students will not take the initiative to check and correct them. This phenomenon is a comprehensive manifestation of many factors.

3. Play the role of "group leader" and "little teacher". There are 37 students in the class. If every student's homework is waiting for the teacher to supervise and revise it, it is of course unrealistic. At this time, we should give full play to the role of "group leader" and "little teacher" and launch a small competition to correct homework among groups. For students who have difficulty in correcting homework, let the "little teacher" help. Some particularly difficult students are specially tutored by teachers.
