1, knowledge point combing: First of all, we should comprehensively sort out and summarize all the knowledge points involved in junior high school mathematics, and make clear which knowledge points need to be strengthened and which need to be explained emphatically.

2. Teaching methods: According to the actual situation and needs of students, flexible and diverse teaching methods can be adopted, such as explanation, demonstration exercise, case analysis and group discussion. So that students can absorb and master what they have learned more effectively.

3. Exercise: outside the classroom, improve students' math ability through a lot of exercises. You can arrange exercises and correct them in time, or you can guide students to complete exercises independently and provide necessary guidance and feedback.

4. Experimental operation: For some knowledge points with abstract mathematical concepts, students can understand and master them through experimental operation. For example, geometric tools or computer software are used to draw and calculate geometric figures.

5. Popularize application: In the teaching process, you can also introduce and demonstrate the application scenarios of mathematics in reality, stimulate students' interest and motivation in learning, and let them better understand the importance and practicality of mathematics.
