1 first of all, find out the shortcomings of your own mathematical foundation.
At present, when most students are in primary school, they have learned Olympiad in extracurricular classes (it doesn't matter if they don't learn or learn well). In fact, it's certainly good to learn Olympic Mathematics well in primary schools, and it's no big deal not to learn it well. More than 80% of the contents of Olympic Mathematics in primary schools are of little help to junior high school exams, but if you want to get full marks in junior high school exams, you must learn and use the remaining 20% freely. Because everyone's situation is different, in my opinion, we must learn to use the following contents of the Olympic Mathematics in primary schools:
(1) Quick calculation, including many contents such as: quick calculation method, some constants (complete square number, pi× n, etc. ).
There are several types of Olympics: planting trees, averaging and traveling.
(3) To improve the speed of Chinese reading comprehension (which is necessary to do practical problems with a large number of words), we should be able to grasp the key points in the process of examination and quickly transform them into mathematical language.
(4) Other things you need.
Step 2 do the questions selectively
I don't advocate sea tactics, because everyone's situation is different. If we adopt the tactics of asking questions about the ocean, it will waste our precious time. So how do you choose a math problem to practice?
If a good teacher teaches you math at school, he or she will help you do it well.
(2) If the teachers in the school are average or not dedicated, then you should choose a good extracurricular teacher to help you.
(3) If your parents are good at math and have time, they can also help you.
3. How to do math problems after class (not counting school teachers)
(1) The questions you do must have standard answers. If you don't have answers, don't do them.
(2) Do the extra-curricular books you bought or the homework left by the extra-curricular teachers. Don't waste time, just know how to do it. Some people don't have to write, step by step, or just write on papyrus.
Step 4 make a summary
(1) Doing math problems is the same as other subjects. Genius doesn't have to make a written summary, but constantly summarizes the problems in his mind or subconscious.
(2) The summary of mathematics must be targeted, and some summaries must be done by yourself, because others don't know your personal situation and can't help you. For example, a geometry problem, you have an epiphany, the auxiliary line is drawn, and the problem is done correctly, but can you guarantee that your epiphany will flash next time you encounter this or similar problem? Therefore, the wrong questions or even the right questions should be marked and reviewed after a while.
(3) For new problems, take notes on the basic knowledge that was not well used when doing the problems.
If you do the above four points, you can get high marks in mathematics, but there is still a certain gap from full marks.
5. Learn to test
Personally, I think the examination of math problems is the most critical and the most difficult to learn math well. Many good students always get high marks in mathematics, but they just can't get full marks. Every exam is deducted for so-called carelessness. The key reason is that the testing method and timing are wrong, so how to test? The following is my personal opinion:
After the math test, it should be clear about right and wrong, and there should be no carelessness.
(1) Math exams are everywhere. In most cases, a problem can be tested by another method (including calculation).
(2) The timing of the exam must be trained, and a good math teacher should slowly infiltrate this aspect in the process of giving lectures. For example, in the process of doing the problem, check the calculation results and do it immediately. It usually takes 10 second or less at this time, but if you do it after the question is finished, it will take at least 1 minute.
Personally, I think that when doing math problems, on the one hand, it is necessary to ensure that on the other hand, it is not necessary to finish all the tests (of course, you can also see if there are any omissions or omissions).
(3) There are too many ways to take exams, and you can only rely on a teacher with high mathematics quality to train step by step. This training process is carried out when explaining any math problem (the general teacher may be afraid of delaying time (in fact, it won't take too much time), and generally don't do it, which is the key for students to get high scores and full marks). As a student, you must study hard the examination method of mathematics, which is the key for you to get high scores and full marks.
Let's talk about this first. These are just personal experiences and personal opinions. If students or parents are interested, we can discuss it again.
The above is what I wrote for junior high school students. For reference, it's similar to high school.
