Lecture notes for senior high school entrance examination in mathematics
Some junior high school students do well in many subjects, but their math scores are poor, which affects their overall grades. Junior high school mathematics is not only the focus of junior high school, but also the difficulty of learning. Is there any way to quickly improve the math scores in the senior high school entrance examination?

First analyze the reasons why junior high school mathematics is not good.

For many junior high school students, the hardest hit area of losing points in math test papers lies in calculation. For the math exam, if you want to get a score, you must first get it right. Many students have a good foundation in mathematics, but they have to deduct unnecessary points because of calculation. Some students like to spend a lot of time on big problems and difficult problems when studying mathematics. I often do or may do big questions in the exam, but I lose points on simple or basic questions that I shouldn't lose. Some students are slow to do problems and have insufficient examination time, which leads to many problems that they can do. Some students are not strict in doing problems, often losing points in details, and some students make mistakes in solving problems, resulting in a total loss.

Second, in a short period of time, how to make mathematics learning from poor to good?

1. Build confidence: I can learn math well.

It is very important for students to get good grades in their studies and believe in themselves. When you are under pressure or don't believe that you can do it completely when doing math problems, it is equivalent to not having 100% efficiency, and the result is not satisfactory. Students will gain a lot if they are interested in the topic and are willing to invest. It doesn't matter if you can't do it temporarily. The stumbling block now is the poor foundation before. However, as long as you work hard and make up bit by bit, you can get satisfactory results. Believe that you have confidence in yourself, and you can easily pass the senior high school entrance examination.

2. lay a solid foundation: learn every question in the textbook well.

In the study of mathematics, we should first master the knowledge points in books and then have a knowledge network for the whole knowledge. In the review process, the exercises at the back of the textbook and the exercises in the supporting workbook are supplemented. Have a thorough understanding of knowledge When reviewing in the early stage, we should focus on textbooks, choose basic questions, simple questions and medium questions when doing questions, and give up difficult questions first. After understanding the knowledge points in the book and establishing a knowledge network, it feels great to do the problem, but you must pay attention to one sentence when doing the problem. Solving problems is not an end. We must know the ins and outs of this problem and understand it thoroughly. Only when there are no big problems in the simple and medium questions in any chapter do you start to do difficult problems.

3. Scoring direction: the calculation ability can pass.

If you want to improve your math scores quickly, the most important thing is to make sure that your calculations are correct and get the marks you deserve. Many junior high school students lose points because of calculation errors, which affects their math scores.

A calculation problem often needs a lot of knowledge, such as four operations, operation sequence, algorithm and so on. Even need to calculate many times to get the result. In the process of calculation, a little carelessness will lead to calculation errors, thus deducting points. Many students will pursue speed in the calculation process and strive to shorten the calculation time, thus improving the efficiency of time utilization. In fact, correct calculation is the most basic requirement, and high speed without correct rate is worthless. In the process of calculation, some students are prone to make mistakes in digital writing during calculation, which leads to calculation errors and points deduction. Therefore, when we do calculus and sketch calculation, we must form the habit of writing numbers carefully to avoid reading wrong data.

4. Review key points: doing questions and speed

The biggest competitive score of mathematics in the senior high school entrance examination lies in the scores of simple questions and medium questions, and students with poor math scores only need to pay attention to these parts. Because the review was not in place, everyone got the scores of simple questions or medium questions, but they lost them, even if they got the scores of big questions, it was not worth it. Lack of examination time should be a concern of most students. The problem-solving speed is slow, on the one hand, because I don't have enough confidence in myself, and I have repeatedly checked and thought about the questions I just answered. When doing the problem, you need to analyze and think about the problem first, and then write down the idea after forming a certain idea, so as to develop the habit of thinking first and then writing. If you think smoothly, you can improve your confidence, answer questions efficiently and shorten your time.

Senior three students should make full use of their time to improve their learning efficiency when reviewing for the senior high school entrance examination. How to make good use of the remaining time is the key to determine the results of the senior high school entrance examination. Although everyone's review time is similar, some people's review effect is better than others, and their grades are improved faster than others. This is the reason for reviewing methods. The correct review method can improve the review efficiency, so as to be one step ahead in the review of senior high school entrance examination. Grade three, poor math performance, analyze the reasons, use the right method, you can change yourself and change your grades!
