Review method of fourth grade mathematics

1. Give full consideration to the characteristics of students' physical and mental development, and design interesting math activities in combination with the knowledge acquired by students through various channels and the life experience accumulated before school, so that students have more opportunities to learn and understand math from familiar things around them. Through the perception of a large number of physical diagrams and the operation of specific models, students can acquire the most preliminary knowledge and skills.

2, lay a solid foundation of knowledge and skills, while focusing on cultivating students' innovative consciousness and interest in learning mathematics.

3. Grasp the key points, difficulties and internal relations of knowledge, so that students can improve on the original basis.

4. Review the knowledge learned this semester in blocks and categories, focusing on the problems that are easy to make mistakes in unit papers, review books and homework, and designing special activities to infiltrate all kinds of mathematical knowledge. The design of special activities can make the content of review comprehensive and give students the opportunity to comprehensively use what they have learned.

5. Strengthen the connection between family education and school education, and properly teach parents some correct methods to guide their children to review.

6. Improve the evaluation of students, pay attention to their own vertical comparison, pay attention to what students have mastered, what abilities they have, and where they need to work hard.

7, according to the usual teaching situation, combined with the review of relevant knowledge points to do a good job of counseling students with learning difficulties.
