As one of the three major subjects, mathematics can only get low marks if it is not well studied. Therefore, before the end of the semester, the review method of mathematics is very important. Children should review according to their own characteristics and strive to meet the arrival of the final exam in a better state.
So, how should we review?
First, check the missing and fill the gaps, and the main attack is weak.
First, make a "loss analysis table", including "I won't do it" and "I shouldn't lose points", analyze the loss of points in test papers such as mock exams, and focus on making up and improving my weak links on the basis of reviewing with the teacher.
Don't just rush to solve the problem. Doing the problem is to further consolidate and verify the theoretical knowledge. We should strengthen practice on the basis of understanding in order to achieve the purpose of consolidation, but we should not blindly pursue difficult problems and digressions. Because 30% of the test paper is elastic, only 10% is true. 30% of the topics are topics that we can get but are easy to lose points. We should get as many points as possible, but if we blindly seek risks, we will lose our due points because we ignore the consolidation and consolidation of basic questions. After mastering the foundation, qualified students can tackle some difficult and strange problems again, so that the strategy can better ensure efficiency.
Second, reflect on the wrong questions
Don't blindly find questions to do, get caught up in the sea of questions, don't try to "do" the final exam questions (except the basic questions), and don't stay at the low level of "I know this question" Improve the ability to solve problems through reflection. Understanding, cognition and understanding are the three levels of mathematics level. In short, I understand, but I don't necessarily understand, let alone really understand.
Send six "golden keys" to open the door of your wisdom-please compare the wrong questions, think and answer the following questions:
1, why didn't I think of that? (missing)
2. Have you ever done a similar problem? (analogy)
3. Why did you do it? (Dig deeper)
4. What did I do wrong? (attribution)
5. What are the rules and methods? (promotion)
6. Is there any other way? (divergence)
Third, overcome unnecessary points.
How to avoid mistakes in exams?
Reason: Look too fast.
Coping strategy: 1. Silent reading; 2. Key words are outlined in circles; 3. Drawing approval method.
How to reduce the calculation error?
The apparent reason is carelessness, but in fact it is insufficient computing power. Usually, I don't agree with calculation and think it has no technical content. In fact, there are many "smart algorithms" in calculation, such as: simplifying calculation, adding instead of subtracting, multiplying instead of dividing, decimals, setting the minimum and shortest, scaling, rounding, mirroring and so on.
Coping strategies:
1. Don't skip the calculation in order to catch up with time;
2. I would rather calculate by hand than by mouth, let alone holding a calculator;
3. You can check the problems that are easy to be miscalculated.
Fourth, pay attention to several key issues.
1. New definition problems, unconventional problems and existing problems.
2. Analysis method-holding the cause, reverse thinking, reverse thinking, assuming existence; Incomplete induction-make a bold guess and try to verify it according to examples. Counterexample exclusion method, special graphics (special position, extreme value) exploration method, etc.
Finally, math learning is a process of one link after another, unlike Chinese and English courses, even if you don't keep up at ordinary times, you can recite more at the end of the review to improve it.
For mathematics, if one knowledge point can't keep up, it will definitely affect the mastery of another knowledge point, and even affect the study of physics, chemistry and other disciplines. Therefore, students must be serious again, and don't pull their grades away because of math! Come on!
