Students usually study in class, but we should establish a consciousness that it is also important to have classes before and after class. It is not difficult to learn mathematics well by making good use of these time and cooperating with appropriate learning methods.

Before class: It is very important to preview before class. On the one hand, you can learn the knowledge in class first, so that you can keep up with the teacher's ideas in class. On the other hand, you can mark the knowledge you don't know, so that you can focus on listening in class according to your own situation.

Class: After 45 minutes of class, it is difficult for most students to ensure the concentration of the whole class, which requires us to preview before class, find out what we don't know, and try our best to understand and absorb it in class. I still hope that everyone can concentrate as much as possible in class and follow the teacher's progress to understand the key points and difficulties, which is conducive to review.

After class: The time after class is generally used for review. You can review what you have not mastered, or you can test and consolidate what you have learned in this section. If there are still things you don't understand in the review after class, you must ask the teachers and classmates to clarify.

With the three stages before and after class, I believe that everyone's mathematical foundation is basically the same. I hope everyone will continue to maintain this habit.

2. Improve work efficiency

Many students told Xue Dajun that there was too much homework, and many parents also felt that their children were under great pressure. Children have no time to finish their homework, let alone review anything, which leads to poor academic performance. But have parents and classmates thought about it? Everyone has the same amount of spare time. Why can other students finish it, and even many students use their spare time to sign up for interest classes?

It is possible that our efficiency is not high enough. I can ask you a few questions. Did you concentrate when you did your homework? Did you play with your mobile phone or eat snacks? Will you take a break and often be distracted? If there are these situations, do students still think there is too much homework? Are you not efficient enough?

It may be that the students didn't do the above three steps, which led to their inefficiency in doing homework, and finally it was attributed to more homework.

In fact, this is a very bad study habit, which leads to low efficiency in doing homework. So how can we improve the efficiency of doing homework?

A few suggestions you can refer to:

1 correct attitude

It is estimated that the students have been told by the teacher that if you want to study well, you must first put on a learning posture. There is nothing wrong with this sentence. To treat homework, we should first pay attention to it ideologically and form good habits. However, it is very difficult to stick to a good habit. In this process, many students are easy to give up and have negative emotions. However, you should know that a good habit will benefit you for life. If you form good habits, there will be fewer problems and your grades will naturally improve.

2 concentrate

When you are doing your homework, don't do anything else or think about anything else. You can't do two things at once. Finish your homework as soon as possible before you can do anything else.

3 Learn to summarize

If you can quickly reflect the knowledge points needed for this topic after seeing it, then the speed of doing the topic will be improved, and you should also sum up your own ideas after doing it. To sum up more, you will find that many topics are regular and can get twice the result with half the effort. It can be very easy to encounter similar problems in the future.

4. Create a good learning environment

Try to keep quiet when the children are doing their homework. Don't put anything on the desk except books and school supplies to avoid distracting them. Parents should not nag and reprimand too much, but encourage their children more.

3. Proper Practice Everyone knows that the most important thing in learning mathematics is practice. Usually, doing more basic questions can exercise the proficiency in solving problems, and doing more intermediate questions can familiarize you with the test questions. You are not advised to do more difficult questions. You can try to solve difficulties, master problem-solving skills, and don't blindly train. Learn to summarize when doing questions, and summarize which questions often appear, which may be the questions of the senior high school entrance examination. Some students are doing problems every day, but they have not improved by using a lot of tutorial books. This is doing the problem blindly, without skill and summary.

Students pay more attention to problem-solving ideas, methods and skills. It is very important to master the problem-solving ideas and summarize the problem-solving skills. Time is the most precious in the exam. Mastering good ideas, methods and skills can not only solve problems quickly, but also make mistakes easily.

4. Computational ability calculation has always been a core content of mathematics, and almost every mathematical problem needs calculation. Then, the accuracy of calculation is particularly important. In order to improve math scores, the accuracy of calculation must be improved. So how to improve the accuracy of calculation? I also gave some suggestions here.

1 strengthens students' intentional attention and good calculation habits.

(1) The habit of carefully examining questions. After getting the topic, carefully examine the topic, see the requirements of the topic clearly, and want to understand what problems should be paid attention to in the process.

(2) the habit of careful inspection. Check the train of thought first to see if there are any omissions, and then replace the answer with the original question. If it is a calculation problem, check every step carefully.

(3) the habit of writing carefully. Writing should be clean and tidy, so that you can see the topic clearly and avoid it.

The occurrence of mistakes.

2. Strengthen oral calculation ability

Any calculation is based on oral calculation, and the ability of oral calculation directly affects the improvement of students' other calculation abilities. To improve the ability of oral calculation, we must first do the basic training of oral calculation, so we should practice some oral calculation frequently.

3 Fast calculation and clever calculation

When doing calculation at ordinary times, we should pay attention to the clever use of operation and speed up the operation, especially the fraction calculation part. Sometimes there are many people, and it will be difficult to divide them. At this time, it may be a better choice to write the denominator as a product.

4. Enhance the evaluation ability

Many problems, especially application problems, can be roughly estimated after seeing the problems. With this estimation ability, sometimes the calculation error can be seen at once. So we can also estimate the scope of the answer before doing the problem. If the calculated answer is not within this range, we need to check it.

5 the nature of rational use of some numbers

For example, an odd number multiplied by an even number must be an even number, and a number whose sum of digits is a multiple of 3 must be divisible by 3, which can help us to make some auxiliary judgments on whether the operation is accurate or not.

Having said that, it's actually very simple to sum up. As long as we adhere to good study habits and do review exercises, we can get twice the result with half the effort in mathematics learning, and it is natural to learn mathematics well.

5. Establish the wrong topic As the saying goes, "Once bitten, twice shy", but students often fall into similar or even the same "trap" again and again. Therefore, Xue Dajun suggested that when you do the usual questions, you should record the wrong questions in time. More importantly, you should think about why you are wrong and what you should pay special attention to in the future to avoid unnecessary loss of points. After all, the senior high school entrance examination is still the usual exam, and all the points are very important. You can't lose a point. When reviewing in this way, this wrong book has become a valuable review material.
