1. Record key contents: Listen carefully in class and record the key contents explained by the teacher. Important formulas, theorems and examples can be marked with pens of different colors or highlighters.
2. Clear your mind: When doing a math problem, you can sort out the key information in the problem first, which helps to clear your mind and avoid missing key steps.
3. Sketch: For some geometric problems or functional image problems, you can draw a schematic diagram to help you understand. Try to be concise and clear when drawing, and highlight the key points.
4. Summary: After learning a knowledge point, you can summarize the main contents and problem-solving methods of the knowledge point. It can be sorted out and summarized by forms, mind maps and so on.
5. Consolidation: You can do some related exercises after class to consolidate what you have learned. You can record the wrong questions separately for future review.
6. Review in time: review your notes regularly to deepen your understanding and memory of knowledge points. You can divide your notes into different chapters or topics for easy searching and viewing.
In short, the production of junior high school math notes should pay attention to the recording of key contents, the arrangement of ideas and the induction of knowledge. By constantly doing problems and reviewing in time, the effect of mathematics learning can be improved.
