Summary of Solving Common Fill-in-the-blank Problems in Mathematics for Senior High School Entrance Examination

The main types of fill-in-the-blank questions in senior high school entrance examination are quantitative fill-in-the-blank questions and qualitative fill-in-the-blank questions. The former mainly examines the calculation of computing ability, and also examines the proficiency of candidates in the mathematical formulas involved in the questions. The latter examines the examinee's understanding and proficiency in important mathematical concepts, theorems and properties. The following are the answers to the common fill-in-the-blank questions in mathematics for the senior high school entrance examination, I hope to help you!

Solving methods of common fill-in-the-blank questions in mathematics for senior high school entrance examination

Of course, these two types of fill-in-the-blank questions also penetrate each other, and the understanding and proficiency of specific knowledge only focus on the exam. Choosing fill-in-the-blank questions is different from big questions, which only seek correct conclusions and do not follow the steps. So we can take a shortcut and use some answering skills to sum up three answering skills for this kind of questions.

1. direct method: according to the conditions given by the stem, the correct answer can be directly obtained through calculation, reasoning or proof.

2. Illustration: Provide information according to the stem of the question, draw a graph and get the correct answer.

Although the fill-in-the-blank questions are mostly low-graded, many candidates often make mistakes in answering questions, which should attract our attention.

First of all, fill in the blanks according to the requirements of the questions. For example, sometimes fill-in-the-blank questions have some additional conditions for the conclusion, such as answering with specific numbers and being accurate. It is a pity that some candidates do not pay attention to this and make mistakes.

Secondly, if there are no additional conditions, the questions will be answered according to specific situations and routines.

Third, we should carefully analyze the implicit conditions of the topic.

In short, fill-in-the-blank questions are the same as multiple-choice questions, because you don't need to write the problem-solving process, just write the final result. So don't fill in, fill in too much, fill in the wrong, only part of it is correct, strictly speaking, it is zero. Although it is not difficult to fill in the blanks in the middle school entrance examination in the past two years, the scoring rate is not ideal. Therefore, laying a good foundation, strengthening training and improving problem-solving ability can solve problems accurately and quickly. On the other hand, strengthen the analysis and research of fill-in-the-blank questions, master their characteristics and solving methods, and reduce mistakes.

Four relationships should be handled well in mathematics for senior high school entrance examination

1. The relationship between examination and problem solving. Some candidates do not pay enough attention to the examination of questions, are eager to achieve success, and rush to write, so that they do not fully understand the conditions and requirements of questions. As for how to dig hidden conditions from the problem and stimulate the thinking of solving the problem, it is even more impossible to talk about it, so there are naturally many mistakes in solving the problem. Only by patiently and carefully examining the questions and accurately grasping the keywords and quantity in the questions (such as? At least? ,? a & gt0? And the range of independent variables. ), get as much information as possible, so as to quickly find the direction to solve the problem.

2.? Can you do it? With what? Score? The relationship. To turn your problem-solving strategy into a scoring point, it mainly depends on accurate and complete mathematical language expression, which is often ignored by some candidates, so it appears in a large number of test papers? Will it be right, but not all? The situation, the examinee's own evaluation score is far from the actual score. Like the argument of solid geometry? Jump? So many people lost the score of 1/3 or more; In algebraic argument? Want to prove it? Although the solution is correct or even clever, it is not good at putting it? Graphic language? Accurate translation? Text language? , the score is pitiful; Another example is the image transformation of trigonometric function in one year's senior high school entrance examination. Many candidates? Know fairly well? I don't know, and there are not a few people who deduct points. Only pay attention to the language expression in the process of solving problems. Can you do it? Ability problem? Score? .

3. Fast and accurate relationship. In the current situation of large amount of questions and tight time, is it accurate? Words are particularly important. Only? Quasi? In order to score, only? Quasi? So you don't have to consider taking the time to check. And then what? Quick? It is the result of usual training, not a problem that can be solved in the examination room. If you try to be quick, you will only make many mistakes in the end. For example, there is an application problem in the one-year senior high school entrance examination. It is not difficult to list piecewise analytic functions, but quite a few candidates miscalculate quadratic functions or even linear functions in a hurry. Although the following part of the problem-solving ideas are correct and take time to calculate, but almost no points, which is inconsistent with the actual level of candidates. Slow down and be more accurate, and you can get a little more points; On the contrary, if you hurry up and make mistakes, you will not get points if you spend time.

4. The relationship between difficult questions and easy questions. After you get the test paper, you should read the whole volume. Generally speaking, you should answer in the order from easy to difficult, from simple to complex. The order of examination questions in recent years is not completely difficult, so we should arrange the time reasonably when answering questions, and don't type on a stuck topic. A protracted war? That took time and didn't get points, and the problems that could be done were delayed. In recent years, mathematics test questions have changed from? Questions to check? Turn? Multi-question examination? , so the solution is set at different levels? Steps? It's easy to start with a wide entrance, but it's difficult to solve it in the end, so there will be seemingly easy questions? Bite your hand? Level, seemingly difficult questions are also divided. So you saw it in the exam? Is it easy? The topic should not be taken lightly. See new faces? Difficult? Don't be timid, think calmly and analyze carefully, and you will get the score you deserve.

In addition, we should pay attention to using standardized mathematical language to answer questions. Many students have developed a casual habit when solving problems, always thinking that they can do it. When solving problems, they don't give detailed answers in standardized mathematical language, and the result is often that they lose points that they shouldn't.
