Junior high school math, how to review a model??

Can provide you with methods for reviewing and studying mathematics in the third year of junior high school:

1. Promote memory, so that the results of learning are firmly stored in the brain so that they can be accessed at any time. Some students always complain that their memory is too bad, and they can't remember what they have learned when they should use it, and they lose confidence in learning. Some students think that they should forget what they have learned anyway, and it is useless to memorize it early, and hope for a surprise attack before the exam.

However, because there are too many things to memorize before the exam, I can't remember them, so I feel very annoyed.

2. Check and fill in the gaps. There are many factors that affect learning, and it can be difficult to ensure that all factors are in the best condition in a long learning process. Therefore, it is inevitable that there will be loopholes and deficiencies in the complete learning content.

Through review, check it out by yourself and make up for it in time. All students who are in a hurry to review. The loopholes and deficiencies in learning are filled in time, so their knowledge is always relatively complete.

3. The most important point is that you can improve your memory and comprehension to make you learn more with half the effort, which is the most critical point to improve your academic performance. In the previous years, I had a very poor academic performance and a poor memory. Then ** "Nikola Tesla Brain Training", this is a set of courses to develop potential, through the training of the course, my heart has become very calm, memory, understanding, imagination have improved, I have mastered a variety of efficient use of brain skills, by adjusting their mentality, easy self-study of various subjects, and at the same time can achieve the effect of applying what I have learned.

Eventually, I was admitted to the ideal university. I hope my sharing can help you, hope!

Through the mock test, you can objectively understand the current review and preparation of students, provide goals and directions for students' future review and preparation, and also provide some basis and reference for the teacher's future teaching.

After a long period of online classes, many schools are currently starting normal classes, and many schools have started exams just after the start of school, which has caught students off guard, and many students have expected to fail in the exams.

Recently, many students and parents are asking, what should I do if my child does not do well in the first or second model? If you don't do well in the exam, you must find a way to solve this problem, how to solve it?

The simple summary is two words: analyze the situation, study the test questions, determine the goal, make a plan, and do your best to prepare for the exam.

The following aspects need to be paid attention to in the specific operation process:

First of all, we should pay attention to adjusting our mentality, don't lose confidence in yourself because of a failure in an exam, the mock exam is actually to help me find the remaining problems in the review, and it is better to find problems in the mock exam than to make mistakes in the high school entrance examination. Therefore, in order to treat the mock test and results correctly, if the test is not good, it is necessary to summarize and think in time, and do a good job of checking and filling in the gaps and remediating the most important thing

There are still two months to go from now to the high school entrance examination, and there are many large and small mock exams, and the first model has not been well examined, and there are still ...... second and third modelsBut it must not be taken lightly, if you don't do well in the exam, there must be a lot of problems in your own review, so the review work after that must be done more down-to-earth and carefully, otherwise this kind of failure will appear again and again, and it will really be too late when it comes to the high school entrance examination.

1. The learning experience of a female champion of science in the college entrance examination in the 80s: pay attention to methods.

1. Preview before class, review after class, and persist for a long time.

2. Integration: When learning new knowledge, it is also necessary to connect with old knowledge, so that knowledge can be connected and form a system.

3. Grasp the basics: learn deeply and thoroughly.

4. Pay attention to improving your ability to analyze and solve problems.

1. Careful understanding: transform the knowledge of regularity into the wealth of your own mind.

2. Summary and arrangement: make a summary for each class, and then make a specific summary during the unit review and overall review, mainly to have an overall understanding of the knowledge, so that the knowledge structure can form a clearer framework.

3. Serious review: review should be timely, repeated, and diligent in the process of review, so that it will be firmly stored in the brain for a long time.

4. Apply what you have learned: The purpose of memorization is to use, including teaching, arguing, etc.

For example, if you do more exercises in mathematics, the more you use the formulas, the more familiar you will become.

Geography: Mapping, field trips.

History: Compile a chronology, browse monuments, and appreciate cultural relics.

Politics: Analysis of social phenomena.

First, we should pay attention to the review of mathematical concepts. Concepts are the foundation of mathematics, and reviewing concepts is not only to know what they are, but also to know why they are. For each knowledge point, we must know how it came to it and where it was used on the basis of keeping in mind its content, only in this way can we better use it to solve problems.

Second, we should pay attention to listening to lectures in class and summarize and organize them in a timely manner after class. When you take a review class, you should follow the teacher's ideas, actively think about the following steps, and listen to the lecture to be hands, mouth, eyes, ears, and hearts. After class, students should complete their homework carefully and independently, and be diligent in thinking.

After class, you should summarize and sort out the test papers and exercises you have done in a timely manner, and prepare a set of mistakes for some questions that are easy to make mistakes, and write out your own solution ideas and correct solution process.

Third, it is necessary to do more questions appropriately, develop good problem-solving habits, and improve problem-solving ability. If you want to do well in mathematics, it is inevitable to do more questions. At the beginning, you should start with the basic questions, practice repeatedly to lay a good foundation, and then find some improvement questions to help you develop ideas, improve your analysis and solving skills, and master the general rules of problem solving.

It is necessary to summarize the basic solution ideas of various common problems, such as: graphic movement, graphic transformation, inductive exploration, classification and discussion, etc. Understand, be familiar with, and master the characteristics, rules, and basic problem-solving ideas of these question types, and improve the problem-solving ability through a certain number of exercises, and then summarize and train again.

Fourth, there are some skills that need to be mastered during the exam. When the test paper is sent, you should first take a rough look at the amount of questions, allocate time, if you take too much time to solve a question and have not found an idea, you can put it aside for the time being, you will finish it, and then go back and think carefully. For a question with several questions, you can use the conclusion of the previous question when answering the following question, and even if the previous question is not answered, as long as the source of this condition is clearly stated, it can also be used.

In addition, when taking the exam, you should be calm, if you encounter a problem that you will not know, you may wish to use a self-consolation psychology, which can calm your mood, so as to play your best level, of course, comfort is comfort, for those questions that can not be done at once, you still have to think hard, try to do as much as you can, and certain steps are also scored.

1. Be diligent in reviewing.

Be diligent and hands-on: don't look at the questions, be sure to calculate, write down the knowledge points that you don't know, and write them down in your notebook.

Speak diligently: If you have any questions, you must ask the teacher, time waits for no one, and there is no time to waste. And learn to discuss problems with classmates.

Be diligent and use your ears: You must listen to the review class taught by the teacher, don't think that this question will be, the teacher can skip the number, and you must know that you can learn new things by reviewing the past.

Diligent brain: good at thinking about problems, thinking positively about problems - absorbing and storing information.

Exercise your legs: Don't participate in too strenuous exercise to prevent injuries from affecting your studies, but you can exercise and jog for 30 minutes every day to get to your best.

2. How to solve multiple-choice questions.

1. Direct method: According to the conditions of the multiple-choice questions, through calculation, reasoning or judgment, the final result of the question is obtained.

2. Special value method: (special value elimination method) Some multiple-choice questions involve mathematical propositions related to the value range of letters;

When solving this kind of multiple-choice question, you can consider selecting a few special values from the range of values, substituting them into the original proposition for verification, and then eliminating the wrong ones and retaining the correct ones.

3. Elimination method: return the four conclusions given by the question to the original question stem for verification one by one, and eliminate the errors until the correct answer is found.

4. Phase-out method: If we do not do it in one step in the process of calculation or derivation, but step by step, we adopt the strategy of "take a walk and take a look";

Each step is compared with the four conclusions, and the impossible is eliminated, so that the three wrong conclusions are all eliminated if the last step is not taken.

5. Combination of numbers and shapes: according to the internal relationship between the conditions and conclusions of mathematical problems, it not only analyzes its algebraic meaning, but also reveals its geometric meaning;

3. Commonly used mathematical thinking methods.

1. The idea of combining numbers and shapes: according to the internal relationship between the conditions and conclusions of mathematical problems, it not only analyzes its algebraic meaning, but also reveals its geometric significance;

Combine quantitative relations and graphics skillfully and harmoniously, and make full use of this combination to seek disintegration ideas and solve problems.

2. The idea of connection and transformation: things are interconnected, mutually restrictive, and can be transformed into each other. The various parts of mathematics are also interconnected and can be transformed into each other.

When solving problems, if the mutual transformation between them can be properly handled, it can often be difficult and simple.

Such as: substitution transformation, known and unknown transformation, special and general transformation, concrete and abstract transformation, part and whole transformation, dynamic and static transformation, etc.

3. The idea of classification discussion: In mathematics, we often need to examine it in various situations according to the differences in the nature of the research object;

This method of categorical thinking is an important method of mathematical thinking, and it is also an important problem-solving strategy.

In the process of learning mathematics, it is necessary to have a clear sense of revision, and gradually develop good revision habits, so as to gradually learn to learn. Mathematics review should be a reflective learning process. Reflect on whether the knowledge and skills learned are up to the level required by the curriculum; It is necessary to reflect on what mathematical ideas and methods are involved in learning, how these mathematical ideas and methods are used, and what are the characteristics of the application process; It is necessary to reflect on the basic problems, including basic graphics, images, etc., whether the typical problems have really been understood, and what problems can be attributed to these basic problems; Reflect on your mistakes, find out the causes of them, and formulate corrective measures.

You can prepare a math learning "case card", write down the mistakes you usually make, find out the "**" and prescribe the "prescription", and often take it out to see, think about the mistake, why it is wrong, how to correct it, through your efforts, there will be no "case" in your mathematics when you take the high school entrance examination. And mathematics review should be carried out in the process of applying mathematical knowledge, through the application, to achieve the purpose of deepening understanding and developing ability, so in the new year under the guidance of teachers to do a certain number of mathematics problems, so as to do the opposite.

3. Skillfully apply and avoid the tactics of "practicing" instead of "repetition".

Junior high school mathematics is still relatively simple, and the question types in a book are roughly classified. Module-by-module review. Or sell a set of rolls.

If you put your mind to math, you won't be disappointed. (*

It is right to have a firm grasp of the knowledge points in the third year of junior high school, and practice makes perfect after it will be integrated, so that you can learn the third year of mathematics well.

Specific questions, specific analysis, you have to take a picture of the book table of contents to me.

Suggestions: 1. Pay attention to the combination of work and rest, adjust your mentality, don't be too tired, the effect of fatigue is not good;

2. Listen carefully in class, and during the review stage, the teacher will remind you of many questions that are easy to make mistakes and easy to test.

3. Review the commonly used phrases in English, focusing on word pattern transformation and reading comprehension, so as to lay a solid foundation of grammar knowledge and vocabulary. Then focus on single-choice and fill-in-the-blank. If there is a fill-in-the-blank question, you should review the verbs, adjectives, adverbs, and conjunctions in junior high school according to their memory.

4. The grades have been basically stable, and it is very important to adjust the state and review the wrong questions.

5. Summarize more wrong problems. Quickly find a breakthrough for all kinds of problems. Summarize yourself being stuck in **, how to break through in the future.

According to your own situation, focus on grasping and solving those problems that lose a lot of points but can be solved in the short term. For weak key chapters, it is necessary to focus on reviewing.

6. The usual score of mathematics rarely reaches 85 88%, so don't do too many finale problems, and grasp the mid-range questions and easy-to-mistake questions. The finale puzzle is generally novel and unlikely to be encountered. Arrange your own time, fill in the blanks and grasp the last question, and don't waste too much time.

Work more on other subjects.

7. If you have any problems with your homework that day, especially if you haven't solved it for a long time, ask the teacher or classmates as much as possible, don't be embarrassed. Don't wait for the teacher to speak. Because at that time, you didn't know that you couldn't think of it.

8. Pay proper attention to the test-taking skills and the arrangement of the test time, and get as many points as possible.
