1. Listen carefully in class and review in time after class. ? The acceptance of knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek the correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, we should recall the knowledge points the teacher said before doing various exercises, and correctly master the reasoning process of various formulas. If we are not clear, we should try our best to recall them instead of turning to the book immediately. In a sense, you should not create a learning way of asking questions if you don't understand. For some problems, because of their unclear thinking, it is difficult to solve them at the moment. Let yourself calm down and analyze the problems carefully and try to solve them by yourself. At every learning stage, we should sort out and summarize, and combine the points, lines and surfaces of knowledge into a knowledge network and bring it into our own knowledge system.

2. "A good memory is not as good as a bad writing". ? Mathematics is rich in content and the classroom capacity is generally large. In order to study mathematics systematically, we should pay attention to cultivating the habit of taking notes in class from junior high school. Taking notes in class can also inhibit distraction and improve the efficiency of listening to lectures. Generally speaking, in addition to recording the lecture outline, class notes mainly record the key points, ideas, methods and content summary explained by the teacher in the lecture. Pay special attention to write down some experiences and problems in class at any time. Listening is the basis of "listening" and "memorizing" and cannot be influenced by "memorizing".

The way to learn math well is to do more problems.

It can be understood as sea tactics, but it is not the same as sea tactics, because it is almost impossible to learn mathematics without doing problems, but it is also harmful to do more problems blindly without reflecting and summarizing. The most taboo of mathematics is that it seems that you can do it, but you get stuck when you do it yourself.
