Who told me how to revise math in junior high school 20

To find the college entrance examination math questions over the years, you can do multiple-choice questions first, and then figure out the questions of the same question type in all the test papers one by one, and finally find a few college entrance examination mock questions to do.

1.First of all, read the conceptual things in the textbook, you must understand them, otherwise you will have no idea to do the questions.

2.Do some typical questions and look at the papers that have been taken in previous exams. Pay special attention to the wrong topic.

3.I recommend buying a copy of "Challenging the Final Questions of the High School Entrance Examination". This is basically the finale question at the end of the high school entrance examination!

Not much advice, hope it helps.

I am a freshman in high school, so I can say that I have only crossed this hurdle, so I have a few suggestions.

1. Face yourself. From the moment you come up to ask such a question, you know that you should not be very good at math, so you should listen carefully in class, which is the main thing. Otherwise, no matter how many questions you do, it will be in vain.

2. In the second half of the third semester of junior high school, the teacher will review systematically, and you can follow the teacher's footsteps to turn over the past mistakes. Of course, you can't afford to leave the basics behind.

3. There is a lot of homework in the third year of junior high school, and I have a deep understanding of it. Therefore, it is not recommended to hold a few reference books until night, and it is important to ensure a certain amount of sleep! So you can find one or two books to choose from depending on your situation.

It is recommended not to buy too many reference books, because there are enough reference materials issued by the junior high school school, there is really no need to buy exercises, there is no time to do it, and secondly, I don't recommend the sea of questions, more is better than fine, in fact, when you do the practice papers, it is not difficult to find that in fact, many questions are only changed to a number, and the topics are similar, so it is recommended to do fine, do less and summarize more, and give you a small suggestion, you can summarize the knowledge points, and use the frequently occurring questions or simple knowledge points. You can also make a mistake book and write down the questions you find difficult, it works, you can try, I wish you a smooth high school entrance examination.

1. On the basis of studying the "Syllabus" and studying the textbooks, prepare for the review class, and pay special attention to the clear teaching objectives.

2. In teaching, it is necessary to fully reflect the position of teachers leading and students as the main body, so as to prevent teachers from inappropriately inspiring and guiding, and to prevent teachers from speaking with eyebrows and students from listening indifferently.

3. Pay attention to the analysis of the problem, grasp the key points and difficulties, speak in a targeted manner, use the fine lecture to highlight the key points, disperse the difficulties, and do not need teachers to talk about "this is very important, must be mastered", "this is a difficult point, to do more and see more" and so on, only let students unconsciously understand your teaching intentions, your teaching can be regarded as successful. Therefore, as teachers, we must pay attention to strengthening the cultivation of our own quality, so as to receive the effect of "lifting weights as light" in teaching.

1.Pay attention to the analysis of the characteristics and connections of various problem-solving methods, analyze the relationship between the conditions in the problem and the results of the trapped problems, connect the problem-solving methods and skills with the basic theories learned, and continue to learn and consolidate.

2.Induction and summary of solution skills: Master the solutions and skills of various types of questions.

3.Textbooks on the knowledge and formulas are the foundation, any knowledge is dependent on textbooks and exists, we should pay attention to textbooks and carefully study textbooks, review, it will be more efficient. Write more and memorize more sample questions in the textbook and continue to expand.

4.Study the test points for each question carefully.

5.Organize the review notes, list the key points and difficulties in the review, and record the review results in a concise and visual form.

6.The schedule is divided into unit reviews, and the schedule lists the main content and methods to be reviewed for each different period of the week, each day.

1. Basic requirements for mathematics review.

The content of mathematics review can be divided into two parts: basic knowledge and basic problem-solving skills. In the review, it is necessary to pay attention to the analysis, comparison and flexible application of basic concepts, basic formulas, basic laws and laws, so as to understand, synthesize and innovate.

The so-called "understanding" is to strive to integrate the basic knowledge and basic concepts of mathematics learned in middle school from part to whole, from micro to macro, from concrete to abstract from multiple angles, at multiple levels, and in an all-round way, and consciously cultivate one's ability to analyze and understand, comprehensively generalize, and abstract thinking. For the review of definitions, theorems, and formulas, it should be done to: figure out the ins and outs, communicate the interrelationships, master the process of deduction, pay attention to the form of expression, summarize the memory methods, and clarify the main uses.

The so-called "synthesis" refers to the refinement and processing of the mathematical knowledge learned in different disciplines, different units, different grades, and different times, from the surface to the inside, and from the shallow to the deep, so as to establish the vertical and horizontal connections between knowledge, so that the knowledge is systematic, organized, and networked, easy to remember, easy to store, and easy to extract and apply. For example, to review the concept of angles, you can summarize them as follows:

1) The angle formed by the coplanar straight line - the angle formed by the straight line and the plane - the angle formed by the plane and the plane is clarified, so as to understand the formation and development of this essential, how the former is expanded to the latter, and how the latter is transformed into the former to solve.

2) Analogous differences between inclination angles, radial angles, and polar angles, so that the concept of angles is clearer and more accurate.

3) In the triangle: the expression forms and characteristics of the same angle, horizontal angle, vertical angle, quadrant angle, interval angle, azimuth angle and other terminal angles, and the application rules and methods are sorted out.

The so-called "innovation" refers to the flexibility, originality, simplicity, criticality and profundity shown in the process of solving problems after integrating basic knowledge. The ability to innovate is not only manifested in the comprehensive use of the knowledge learned to analyze and solve problems, but more importantly, to discover new problems, broaden and deepen the field of knowledge learned, and constantly enhance their adaptability. To this end, each student should pay attention to discovering and digging out the problems that are not in the books and not covered by the teacher according to the knowledge they have learned.

For example, understanding the multiple connotations of a concept, thinking about a problem from different angles (i.e., multiple solutions to one problem), summarizing the rules of solving common problems (i.e., multiple problems and one solution), and discovering ways to solve problems.

If your foundation is okay, it is best to consult the teacher and practice a lot of questions, and regular and quantitative exercises are very effective.

First of all, you need to know what the math test is. The arrangement of the mathematics paper for the high school entrance examination is based on the ratio of 7:2:1, that is, the basic questions account for 70% of the test papers, the intermediate questions account for 20%, and the difficult questions are only 10%.

Secondly, you need to know what kind of school you want to go to and how many points you need in math. If you want to take the provincial key or something, then you should pay attention, you can at least do 90% of the questions correctly, and you can give up on difficult problems, but only if your other subjects are not bad. If you are going to an average school, you must first make sure that 70% of your questions are correct, and 20% of the intermediate questions just need to do your best.

You can leave the puzzle alone. If you just want to go to high school, practice the basics every day. Seventy percent of the time you get it right is fine.

Thirdly, we must know ourselves correctly. Know your level. At this time of the third year of junior high school, you should do things according to your own ability, and if you don't want to be at a good level, you have to strive for 10% of the problems, so there is no need, but it will affect you and you will not be able to figure out what you know.

But if you're okay, 10 percent is a good motivation.

Finally, we should persevere in the study of mathematics, have confidence in mathematics, and have a good attitude even if our level is not high, and there will be qualitative changes when the accumulation of quantity reaches a certain level.

Good luck with the exam.
