The purpose of careful preparation before class is to listen to the teacher better. Through preview, the mastery level should reach 80%. Listen to the teacher answer these questions with questions that you don't understand in the preview. Preview can also improve the overall class efficiency.
Specific preview method: finish the topics in the book and draw the knowledge points. The whole process lasts about 15-20 minutes. If time permits, you can also finish your homework. ?
If you want to get high marks in the exam, you can't lose points in choosing topics, filling in the blanks and calculating problems. You can't be distracted in the math exam and think about what to do if you don't do well in the exam. In general, the final exam questions are all you don't know how to do, but you may suddenly understand. When you encounter this kind of problem, you should be calm and analyze it with all the conditions given to you.
For example, there were two blank clocks in this exam, and there were several questions to fill in at the end of last year. These conditions are of great help to your problem solving. There is plenty of time for mid-term and final exams, so we should slow down, not as soon as possible, and strive for one-time success. The inspection will take about 3 to 5 minutes.
Skills to learn mathematics well 1, and prepare well:
In the unit preview, we can read roughly, 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 concepts, formulas and laws that are difficult to understand, so that we can listen to the class with questions.
2. Listen carefully:
Listening to lectures should include listening, thinking and remembering. Listen, listen to the ins and outs of the formation of knowledge, listen to the key and difficult points, and listen to the answers and requirements of examples. Thinking, one is to be good at association, analogy and induction, and the other is to dare to question and ask questions. Taking notes means taking notes in class-methods, doubts, requirements and precautions.
3. Seriously solve the problem:
Classroom exercises are the most timely and direct feedback, and must not be missed. Don't rush to finish your homework, look at your notebook first, review your learning content, deepen your understanding and strengthen your memory.
4, timely error correction:
Classroom exercises, homework, tests and feedback should be consulted in time, the causes of wrong questions should be analyzed, and relevant calculation training should be strengthened when necessary. Ask your classmates and teachers if you don't understand. Don't let the problem hang in the air. Get into the good habit of doing things today.
The above are the methods and skills that I have summarized for junior high school students to learn math well, which are for reference only and I hope to help you.
