How to get the perfect score of 150 in junior high school mathematics 139?
When you first enter junior high school, you will find that it is very different from primary school, with many subjects and a wide range of knowledge. Mathematics, in particular, has developed from concrete to abstract. It is important to have a good teacher to learn math well, but good learning methods and habits are more important. Here are some ways to teach you to learn math, you should remember and work hard.

1. Do a good preview: read roughly in the unit preview to understand the learning content in the recent stage, read carefully in the classroom preview, pay attention to the formation process of knowledge, and record the difficult concepts, formulas and laws so as to listen to the class with questions. Persisting in preview, finding doubts and changing passive learning into active learning can greatly improve learning efficiency. Oh, interest is the best teacher.

2. Listen carefully: Listening should include listening, thinking and remembering. Listen, listen to the ins and outs of the formation of knowledge, and listen to the key and difficult points (remember the doubts in the preview? Listen carefully), listen to the solutions and requirements of examples, listen to the mathematical ideas and methods involved, and listen to the class summary. Thinking, one is good at association, analogy and induction, and the other is daring to question, ask questions and make bold guesses. Remember, of course, it means class notes, either more or more effective, you know? If it affects the class, it is better not to remember when, but to learn. Remember methods, skills, doubts, requirements, pay attention, and remember to take notes after class.

3. Seriously solve the problem: classroom practice is the most timely and direct feedback, and you must not miss it. Don't rush to finish your homework. It is very important to look at your notebook first, review the learning content, deepen your understanding and strengthen your memory.

4. Timely error correction: class exercises, homework, tests, review in time after feedback, analyze the reasons for the wrong questions, and review the questions. Is there a problem? Is the concept blurred? Time is tight, no time? Won't you do it? Don't let your carelessness succeed. If the thinking is correct and the calculation is wrong, correct it in time and strengthen the training of relevant calculation when necessary. Fuzzy concepts and mistakes in examining questions all indicate that you are prone to be ignorant in your study, which is a taboo in learning mathematics and should be resolutely overcome. As for what you can't do, of course, you should ask your classmates and teachers in time. Don't let the problem hang in the air. Get into the good habit of doing things today.

5. Learn to summarize: Adults often say that mathematics is the link, which means that knowledge is closely linked. Summarizing by stages can not only play a role in reviewing and consolidating, but also find the connection between knowledge. The purpose, necessity and knowledge of learning can be clearly understood and integrated, and the methods of solving problems can be done quickly. Even if the questions are not practiced in class, they can be handy, that is, they can be generalized.

6. Learn to manage: manage your own notebooks, exercise books, correction books, and all the exercise papers and test papers you have done. This is the most useful information when reviewing for the big exam, you know?

The above six steps are very effective and must be adhered to. I believe you can learn math well.
