Preview before class is the premise of learning mathematics well. In the preview, find the difficulties and key points of knowledge and find the weak links of learning. Emphasis and difficulty are the key points of classroom listening. The weak links in learning should be reviewed in time, so as to make up for the gaps and reduce the difficulty of our lectures. Compare the knowledge learned through preview with the teacher's teaching knowledge to see how self-study ability is, and help yourself to continuously improve your thinking ability.

The second point: improve the efficiency of math class.

1. Listen to the beginning and end of the teacher's lecture.

Generally, the teacher's introduction at the beginning of class will summarize the main points of last class, suggesting that the key content to be taught in this class is to review old knowledge and put forward new knowledge. The teaching at the end is a summary of the knowledge taught in this class, and it is an important knowledge point that teachers can help students understand.

2. Devote yourself to classroom learning.

Fully preview before class and prepare textbooks, exercise books and related stationery; Mobilize your mental state, greet the teacher's class with full enthusiasm, and concentrate on participating in the class.

Listen. Listen attentively to every link of the teacher's lecture and see how the teacher analyzes, solves and chooses the angle of thinking. Pay attention to how the students answer the teacher's questions and see what inspiration they can get from them.

Yes Think hard, keep up with the teacher's teaching steps and see how the teacher analyzes the key points and solves doubts.

Look at that. In class, we should not only read the textbook and the teacher's blackboard carefully, but also look at the teacher's teaching manners and gestures, and fully absorb the essence of the teacher's teaching.

Go ahead. Actively participate in the teacher's answering questions, actively discuss problems with classmates, and dare to express their views.

Go ahead. To understand, see, think through and make it clear, we must do the classroom exercises and after-school exercises carefully, be strict with ourselves, be careful in all calculations, and be clear in all thoughts. Write down the knowledge points clearly in the notebook and take notes of your own learning opinions.
