Answering questions is the embodiment of mastering knowledge points, and mathematics answering skills are particularly important for students to learn and do. The following are the skills I have compiled for you about filling in the blanks in junior high school mathematics, hoping to help you. Welcome to read the reference study!

1 junior high school mathematics choice fill-in-the-blank answering skills

The quality of the answers in the math test paper mainly depends on the basic skills on weekdays. As long as the "double basics" are solid, the scene is not chaotic, the examination of questions is heavy, the thinking is heavy, and the situation is light, then the results will not be bad. Don't panic, and don't underestimate your enemy blindly. You think you usually do well in math. If you read the first few simple questions, you will be ecstatic and lead to "carelessness" Either there is an error in the examination of the test questions or there is an error in the calculation of the data, which is also an important reason for the abnormal performance of the test. We should take the exam seriously, take every question seriously, and check four things: (1) to make the calculation accurate. (2) Do a good job in the exam questions and understand that "it is better to judge three points than to grab a second answer". (3) Formulating expression standards. (4) Synchronize good thinking and writing.

First, let's analyze the characteristics of multiple-choice questions. Different from big questions, multiple-choice questions only seek correct conclusions and do not follow steps. Therefore, when answering questions, we should emphasize the word "choose", minimize the writing process, make full use of the information provided by the stem and options, and choose the solution flexibly, skillfully and quickly according to the specific characteristics of the topic, so as to gain quick wisdom. This is the basic strategy to solve multiple-choice questions. Basic principles of solving multiple-choice questions

2 Mathematics multiple choice questions answering skills for senior high school entrance examination

Correct reading habits improve the accuracy of understanding.

Mathematics problems in junior high school are more complicated than those in primary school, which requires students to have better ability to analyze and solve problems. Therefore, how to prepare and understand the meaning of the question as soon as possible is particularly important. For example, when choosing fill-in-the-blank questions, there are often right or wrong choices. Students can effectively avoid answering mistakes after marking keywords such as "correct" and "wrong". In the process of solving application problems, marking keywords such as "multiple", "equal" and "how much" which reflect the equal relationship can greatly reduce the time for students to establish equations and solve them; When using graphics to prove or solve problems, learn to mark the mathematical language in the problem with specific symbols on the image, so that abstract thinking can be visualized, which can better assist students to realize logical proof.

The correct answer order can often get twice the result with half the effort.

Generally speaking, it is necessary to cultivate students' habit of answering questions from easy to difficult, but it is often difficult for many children to strictly implement them in exams. Take the senior high school entrance examination in Shenzhen as an example. The examination methods are usually 12 multiple-choice questions, 4 fill-in-the-blank questions and 6 solution questions. Among them, the last two multiple-choice questions, the last question of the fill-in-the-blank question, the last question of the penultimate question and the last big question are more difficult. In the process of answering questions, if students encounter difficulties in choosing the difficult part of filling in the blanks, they can consider guessing an answer first and then answering other confident questions. This can effectively avoid the waste of valuable answering time.

Good writing habits are equivalent to invisible dots.

Good writing habits are reflected in clear and neat handwriting and complete and smooth answer format. Neat and clear handwriting is particularly important in any subject, especially mathematics. Under normal circumstances, mathematical problem solving is divided into several questions, and the answering process is relatively long. If students can divide the limited answer area into several pieces. Not only is it convenient for you to check the answers, but you can also use the teacher to correct the papers. The most taboo for students to answer questions is the writing order of "greedy snake", and the appearance of a large number of alterations will also affect the teacher's marking.

3 mathematical choice fill-in-the-blank answer strategy

exclusive method

Because the answer to multiple-choice questions lies in the choice, if the scope of the answer is narrowed according to the conditions of the topic, some obviously wrong items in the choice may be excluded, and the probability of choosing the right one will be greatly improved, which is mainly suitable for comparing size types, finding analytical formulas, determining function images and other issues.

Example 1 shows that the function f(x)=2mx2-2(4-m)x+ 1, g(x)=mx. If at least one of the values of f(x) and g(x) is positive for any real number x, the value range of the real number is (8) C. (20. Then substitute m=2 to verify whether it meets the meaning of the question If m=2, there is f (x) = 4x2-4x+1= (2x-1) 2, and the function value of this quadratic function is f (x) >; For x∈R and x≦■, 0 is a constant. Now we only need to consider whether the function value is positive when g(x)=2x. This is obviously a positive number. Therefore, m=2 meets the meaning of the question, excluding options A, C and D that do not contain m=2. So choose B.

Eigenvalue method

When solving mathematical problems, if you want to prove that a problem is correct, you must prove that it is correct in all possible situations, but if you want to deny a problem, it is enough to give a counterexample. Based on this principle, when solving multiple-choice questions, we can verify the options by taking some special values, special points, special functions, special series, special figures, special positions and special vectors. In this way, you can deny and exclude those that do not meet the requirements of the topic. According to the information that only one of the four options meets the requirements of the topic, the option that meets the requirements of the topic can be obtained indirectly, which is a special strategy to solve multiple-choice questions.

Example 2 It is known that the sequence {an} satisfies ap+q=ap+aq for any P, q∈N and a2=-6, then a 10 is equal to () A.- 165b. -33c。 -30d。 -2 1. Take one. Analysis: The direct solution strategy of this problem is difficult to write. Choosing a special series that meets the requirements of the topic can concretize abstract problems and solve them quickly. Using specialization strategy is the best strategy to solve multiple-choice questions in college entrance examination. When solving problems, we should pay attention to the following: (1) The selected special case must be simple and meet the problem-solving conditions; (2) the special can only deny the general, but can't be sure of the general; (3) When choosing a special case, when two or more options are correct, you need to choose another special case to replace the test according to the requirements of the topic until all the wrong options are eliminated and the correct choice is achieved.

4 Junior high school mathematics methods and skills

Pay attention to the study and accumulation of basic knowledge of mathematics

Try to preview carefully before class, listen carefully in class and review in time after class. For a long time, many students don't care much about learning the basic knowledge of mathematics, thinking that the basic knowledge is not used to solve problems, especially the concepts, definitions and theorems of mathematics will not be directly tested in the exam, and it is useless to learn them. In fact, this idea is a very fatal mistake. At present, many students have strong learning ability and are smart, but they ignore the study of basic knowledge and fail to grasp the key points of study. Finally, they regretted not learning math well.

In fact, in the senior high school entrance examination, about 80% of the questions are directly or indirectly related to the basic knowledge, and only 20% of the questions are what we call difficult questions, but these problems are also a combination of many basic questions. So if you want to learn mathematics, you should and must learn the basic knowledge of mathematics first. So how to learn the basics? My method is to preview before class, listen in class and review after class. As long as these three aspects are persistently combined, I believe that the final students' math scores will be improved.

Cultivating and training the methods and skills of solving mathematical problems

Do more targeted synchronous exercises with appropriate difficulty, step by step, and cycle by cycle. Many students work very hard in the process of learning mathematics, and they also know that they have to do a lot of exercises. Some even consciously stipulate the number of exercises to be done every day, but the final improvement of mathematics scores is not obvious. Why is this? I think it is largely because the exercises these students do are not targeted.

As for doing the problem, my opinion is not only to do it, but also to do it well. What I want to say here is that the exercises we have learned and thought about are carefully selected by teachers and tested by countless students, which can be said to be very targeted. Of course, many exercises in the bookstore are also very good. I hope you can choose carefully. At the same time, we should not only do targeted exercises, but more importantly, we should constantly sum up and reflect on the exercises we have done, and sum up why we did something wrong, where we did it wrong, what the correct thinking is, and so on. As long as we think about it repeatedly, I believe that our students' academic performance will be greatly improved.
