Bold trade-offs —— Ensuring a relatively high score in mathematics in the senior high school entrance examination
"If you don't do something, you can make bold choices to ensure a relatively high score in mathematics in the senior high school entrance examination." In view of how to prepare for the exam, the famous math teacher said that there must be a choice in preparing for the exam these months.
"First of all, we must conduct a comprehensive review of the basic content, and we must not miss anything; Secondly, we must base ourselves on the foundation, the difficulty is moderate, and it is too difficult to give up. On the basis of comprehensive review, once again make clear what you know but are not very clear.
Learn to choose when doing problems, and never do them indiscriminately. Even the homework assigned by the teacher, students are advised to do it selectively. If they have mastered it well, don't do any more. Do problems that seem to be possible but not sure, and give up problems that have no feeling at all. Don't look around for examination questions from various schools to do, because there is no pertinence and it wastes time and energy. "
Don't lose a cent of the basic knowledge.
A senior math teacher in a foreign language school suggested that candidates should strengthen the combing of knowledge network in the preparation for the senior high school entrance examination and master the knowledge points required by the outline of the senior high school entrance examination.
"First of all, we must sort out the knowledge network, so as to have clear thinking and know ourselves. Thinking about what middle school mathematics has learned, and what are the rules of textbook typesetting? Thinking about these two issues is actually combing the knowledge network and having a good concept of knowledge. " He said, "Secondly, we should master the outline of mathematics and be aware of the exam. Mastering the outline of mathematics in the senior high school entrance examination this year, using the outline to guide the outline of knowledge, mastering the necessary basic knowledge and basic calculation, and ensuring that the basic knowledge is not lost, is another step closer to doing a good job in the answer sheet of mathematics in the senior high school entrance examination. Focusing on reviewing according to the outline and your actual situation can also improve the efficiency of using limited time. "
Do a good job in the final sprint of mathematics in the senior high school entrance examination
It's getting closer and closer to the senior high school entrance examination. On the one hand, we need to study normally according to the review progress of the school. On the other hand, because everyone's learning situation is different, it is necessary to check the knowledge points and missing points repeatedly, find the shortcomings and fix them accurately.
Stick to the method of summarizing the last question in time every day, and the wrong question will play a role. Finally, practice a set of simulated test papers every week and summarize the test questions in time. Our principle of solving problems is to understand the wrong questions first and then do new ones. If you don't have time to do new questions, it is a more effective learning method to spend more time thinking and precipitating wrong questions.
The senior high school entrance examination is an optional exam, and nervousness is inevitable. As long as you are not overly nervous, moderate nervousness is necessary, and you are not the only one who is nervous. Everyone is nervous. Finally, we should understand that it is not the finale but the simple question that determines the success or failure of the senior high school entrance examination. Don't be reluctant to give up difficult problems, just do what you can and don't lose points, which requires you to concentrate on doing problems at ordinary times.
Develop a good habit of answering questions at ordinary times.
Training for thousands of days, with a period of time, there are several ways to test the skills of the senior high school entrance examination: the habit of solving problems should be correct, because it is a computer marking, so you should develop the habit of writing left-aligned columns when answering questions; I will get into the habit of reading questions, and the senior high school entrance examination papers will be issued in advance. Candidates can use this time to browse the test paper, get a general understanding of the problem-solving quantity and types, and understand the difficulty of the test paper, so as to have a good understanding of the whole paper and grasp the overall situation. In the habit of answering questions, it is easy first and then difficult, and the time for answering questions is reasonably controlled. Candidates are particularly nervous after entering the examination room. You can pat your forehead a few times and take a few deep breaths, and the tension will be relieved.

Time planning for solving problems
I can't finish the exam, but I spend most of my time on difficult problems, but I am thinking about the serious consequences that I can't do. When you encounter a problem, you should jump.
Avoid losing points when reviewing questions.
There are many cases of losing points in the exam because of carelessness (looking at the conditions more, looking at the conditions less and reading the conditions wrong). Why is this happening? Because we usually do too many problems, when we encounter similar problems, we will be fixed in thinking, preconceived and subjective, thinking that it is a problem we have done before, without thinking. For example, finding a point on the parabolic symmetry axis is likely to be regarded as finding a point on the parabola or finding a point on the Y axis; The direction of movement is mostly from bottom to top, from left to right, and it is customary to think that this is the understanding; A point on a line or segment, etc. Once the wrong question is examined, it wastes a lot of time, so don't worry, look at it word by word, you can hold on to this heart and examine the question well.
Learn to check
Check to be focused, check a person's concentration, and have the patience to review the questions that have been done.
Of course, it is also necessary to check whether the objective questions on the answer sheet are wrong and whether the format conforms to the regulations (fractional equation test, unit, solution and proof, classified discussion, etc. ).
Finally, check the calculation, and pay attention to the correct attitude when checking.
What should I do if I get stuck in a mid-range problem?
Stay calm, it's not the topic itself that affects you, but your inner distractions. At this time, you should jump out of the whirlpool of thinking and don't doubt your ability. What you should suspect is that you have made a mistake in reviewing the questions, re-examine the questions decisively, or try conventional problem-solving methods.
Strive for more unexpected points.
The marking teacher usually looks for the answer first, and then looks at the steps if the answer is correct. If the steps are not rigorous, deduct 1-2 points. If they can't find the answer or the answer is wrong, start over and see if they can give points, so the writing should be standardized and neat.

Solving problems in the final exam of mathematics for senior high school entrance examination
Learn to use the idea of combining numbers and shapes
The idea of combining numbers with shapes refers to a mathematical idea that studies the relationship between numbers by using the properties of geometric figures to seek the solution of algebraic problems, or studies the properties of geometric figures by using the relationship between numbers to solve geometric problems. Throughout the country in recent years, most of the final exam questions are related to the plane rectangular coordinate system, which is characterized by establishing the corresponding relationship between points and numbers, that is, coordinates. On the one hand, we can study the properties of geometric figures by algebraic methods, on the other hand, we can get the answers to some algebraic problems through geometric intuition.
Learn to use functions and equations.
Starting with the analysis of the quantitative relationship of the problem, the unknown number is set appropriately, and the quantitative relationship between the known quantity and the unknown quantity in the studied mathematical problem is transformed into a mathematical model of equations or equations, so as to solve the problem. This is the thinking method of the equation. The key to solving problems with equation thinking is to construct equations (groups) by using known conditions or conclusions in formulas and theorems. This idea is widely used in algebra, geometry and real life.
Straight line and parabola are two important functions in junior middle school mathematics, that is, linear function and quadratic function. Therefore, no matter how to find its analytical formula and study its properties, it is inseparable from the idea of functions and equations. For example, to determine the resolution function, it is often necessary to establish equations or equations and solve them according to known conditions.
