Second, the national college entrance examination mathematics test paper answering skills
1. For the problems that can be done, we should solve the long-standing problem of "being right but not complete". Some candidates know how to do the problem, but the final answer is wrong-right but not correct. Some candidates have logical defects or conceptual errors, or lack key steps. Therefore, for the problems that can be done, we should pay special attention to solving the math problems in the college entrance examination. Prevent being "segmented". Experience shows that the marking teacher pays more attention to finding the reasonable components of the questions that candidates can do and gives points in stages, so "it is easy to get one or two points for the questions that cannot be done, and it is difficult to get full marks for the questions that can be done".
For the vast majority of candidates, it is more important to score from the questions that can't be found. We say that what kind of problem-solving strategy there is, what kind of scoring strategy there is. Write down the real process of your problem solving, which is the whole secret of "grading by sections"
(1) missing step solution. If you encounter a difficult problem, it's really chewy. A clever strategy to solve a problem is to break it down into a series of steps or small problems. Solve some problems first, and solve as many as you can. Write a few steps if you can count them. Failure is not equal to failure, especially those problems with obvious problem-solving level or procedural methods.
(2) Jumping to answer questions. It is common that the process of solving problems falls into a transitional link. At this time, you can admit the intermediate conclusion first, and then push it backwards to see if you can draw a conclusion. If not, it means that this practice is wrong and change the direction immediately; If we can reach the expected conclusion, we will come back and concentrate on overcoming this "stuck place". Due to the limitation of examination time, if it is too late to overcome the "stuck place", you can write down the previous one and then write "After confirming a certain step, continue to have it." Maybe, we will figure out the middle steps later, so don't plug it in at random at this time, but fill it in at the back. If the topic is,
(3) Reverse solution. "Retreat for progress" is an important problem-solving strategy. If you can't solve the problem, then you can go from general to specific, from abstract to concrete, from complex to simple, from whole to part, from strong conclusion to weak conclusion. In short, retreat to a problem that you can solve. In order to avoid the misunderstanding of "generalizing", you should come straight to the point.
(4) Auxiliary solutions. A complete theme solution includes major substantive steps and minor auxiliary steps. Before finding the substantive steps, it is wise to find the auxiliary steps, such as drawing accurately, translating the conditions in the topic into mathematical expressions, setting the unknowns of the application questions, etc. On the answer sheet, we should be slow and steady, well documented, step by step, strive for a success and improve the success rate. See if there are empty questions, whether the answer sheet is accurate, whether the letters written are consistent with the graphics in the questions, and whether the format is standardized. In particular, it is necessary to check whether the letters and symbols are copied incorrectly, and the papers can only be handed in after they are confirmed to be correct.
Candidates must always pay attention to improving themselves and strive for full marks in solving problems. Then, we must carefully read the perfect score answering skills of the college entrance examination mathematics problem solving, and wish the candidates excellent results.
3. Which provinces use National Volume A?
Applicable areas: Yunnan, Guangxi, Guizhou, Sichuan and Tibet.
Fourth, the difference between the national volume A and B.
1, Volume B is more difficult than Volume A. The English and physics subjects of Volume B are obviously more difficult than Volume A, but some students think that Volume A is more difficult, which is judged according to the general level of students' study. But the college entrance examination will use B and A papers.
2. Volume B and Volume A are used in different provinces. Provinces that use Volume B: Shanxi, Hebei, Henan, Anhui, Hubei, Hunan, Jiangxi, Fujian, etc. Provinces and regions that use Volume A: Shaanxi, Chongqing, Qinghai, Xinjiang, Jilin, Liaoning, Inner Mongolia, etc.
3. The subject contents of Volume B and Volume A are also different. B subjects: English and comprehensive; One subject: Mathematics, Chinese and English.
