(1) First of all, arrange the homework scientifically and reasonably:

1. Prepare homework before class. Homework preview is an important way to change students' attempt to explore and learn independently and cultivate students' learning consciousness and habits.

2. Arrange flexible operation. According to students' mathematical knowledge and ability level, teachers divide students into three grades: excellent, average and poor. After-school homework also designs flexible homework for the three grades, that is, they must do problems, choose topics and expand problems.

3. Arrange the application work. Weak application consciousness is an important problem in current mathematics education. In teaching, we can choose some typical problems, return to their prototypes in life and production, create a practical background for students, let them carefully observe and collect data, abstract graphics, associate students' knowledge and skills, solve practical problems, realize that mathematics comes from practice, and cultivate students' ability to read, understand, abstract and analyze problems. Conducive to the formation of students' ideological quality and intellectual quality.

4. Arrange typical operations.

(B) Optimize the way of correcting homework

1, correct homework in class. After the new class, Jane's homework can be finished in class, and the answers can be discussed and corrected collectively in class.

2. Train students to mark papers in groups. Teachers should spot-check the homework corrected by the group, understand the situation of homework and correction, and re-approve or correct the obvious problems in the homework face to face.

3. Students grade "homework questions" respectively.

4. Double tracking of operational problems.
