Learning methods of junior high school mathematics;

1, listen carefully. Mathematics learning in junior high school is carried out according to books, and the content of the exam is also set according to books. Therefore, we should pay attention to the key and difficult points explained by the teacher in class and take notes in time.

2. Pay attention to finish your homework. Every time after class, the teacher will leave homework, which is to better consolidate the content explained in class, so we should not have a perfunctory attitude towards homework and finish it carefully.

3. proficient in mathematical operations. Mathematical operation is the foundation, which is very important for the whole junior high school mathematics learning. Only by learning math well can we improve our grades quickly.

4. Understand and remember the basic knowledge of mathematics. Mathematics is a very logical subject, so we need to understand and interpret the regularity of mathematics, that is, the thinking methods and ways contained in mathematics, and learn to draw inferences from others on the basis of understanding. Therefore, learning to understand and remember the basic knowledge of mathematics is another prerequisite for learning mathematics well.

5. Master mathematical thinking. Mathematical thinking is different from Chinese thinking, which requires mastering mathematical thinking, learning to transform and divergent thinking in the process of doing problems, and being able to think positively and negatively and solve problems macroscopically and microscopically.
