1. Pay attention to students' mastery and application of basic knowledge. It's not too difficult. For most students, it is most appropriate to answer questions through thinking. Don't let students be intimidated by difficult problems and lose their confidence in learning.

2. Cultivate students' mathematical expression ability, which can express mathematical problems well and reflect students' mathematical thinking and ability to master knowledge. It doesn't matter if the expression is wrong at first, the teacher can correct it in time and then continue to practice.

3. Set up study groups and divide the students into several groups on average. It is sometimes good for each group to set up help objects for students to teach them. Teachers do a good job of supervision.

4. Hierarchical teaching, students with poor learning can have different requirements in homework, reducing the amount of questions and reducing the difficulty. Let students with poor foundation answer simple questions in class, so that they can sometimes feel the happiness of success and pay attention to more inspiring words.
