If you want to learn mathematics well, it's very simple, "question naval battle".
It's okay to do more questions, that's right.
Take out the books and workbooks of the first year of junior high school, do the questions on them one by one, don't miss any of them, ask the teacher if you don't know, redo it after asking, and write down the whole process (you can't go through it in your head, you won't do it if you feel like you'll do it, so it won't work). In fact, it is not enough to rely on the amount on the books and workbooks, you should buy two more extracurricular exercises, a larger amount, one shallower, one deeper, first shallow, then deeper. Maybe you wonder if there is still time to study other subjects?
Of course there is, otherwise how can you say that time is squeezed out? Whenever you have time, you can do math problems, even if it's just for a minute. It's not easy to learn, so you have to be mentally prepared.
We must insist that we cannot fish for three days and dry our nets for two days.

The best thing to do is to make up the lessons.
You can also teach yourself if you think you have what you have.
-
The most effective way to study books is to do more questions. The so-called sea tactics.
But if you really want to learn well, read more books. If you don't understand, ask the teacher.
This kind of thing can't be caught up in a day.
But just try. And it's only the first year of junior high school.
-
Try hard, you can definitely catch up, and so do I.
-
If you have the courage to explore, it is best to prove all the formulas and theorems in the book by yourself, so as to understand the essence of things.
Remember: Math Masters = IQ + Exploration.
Good luck.

1. Failure to preview the textbook in advance, which makes it difficult to quickly understand the essentials of knowledge and master the key parts, resulting in unsatisfactory mathematics results;
2. Failure to follow the teacher's ideas in class to understand the problem, grasp the key points of knowledge, and summarize methods and skills;
3. Failure to consolidate the knowledge learned in time after class, the intensity of practice is small, and the application of knowledge is not proficient;
4. Failure to develop a learning method that conforms to oneself, low learning efficiency, less knowledge gain, and inability to form a complete learning system;
5. Poor mentality, failure to take a correct learning attitude to look at problems, lack of self-confidence and stability of a good attitude.

The remedies for not keeping up with math in the first year of junior high school are as follows:
1. You must listen carefully in class, ask questions if you don't understand, be diligent in thinking, and be diligent in practicing.
2. Pay attention to the summary, I think the test papers of the usual exams are generally the essence of various types of questions, and you must understand each question.
3. After class, do more exercises with various types of questions, which can make perfect, worthy of the name.
4. It is best to use a special book to record the mistakes in the test paper and review them every once in a while.
5. A sense of mathematics needs to be cultivated slowly, and this feeling is more important than any specific mathematical knowledge. Engage in math-related activities as much as possible, no matter what aspect you do, it will slowly improve this feeling, and slowly you will find that what you learn will become easier.
The reason why math is not good in the first year of junior high school
1. Because the foundation is not good, it is not solid enough.
In the process of learning, I am not proficient in memorizing mathematical definitions and formulas, and I am not proficient in basic problem-solving steps and methods. Such students usually think that they can almost do all this when they read books, but when they encounter exams, they find that there are actually many knowledge that they have not fully mastered, and they often encounter the distress of doing ambiguous questions.
2. Because the learning method is not good, I don't have a good grasp of the method of learning mathematics.
Although the concepts, formulas, and basic problem-solving methods of relevant knowledge have been remembered for the time being, they have not been applied in time, and the problem-solving methods have not been consolidated in time, so that after a long time, you will find that the content that has been memorized in a short period of time has been forgotten, or the basic question type will not be done with a slight change.
3. Because of the lack of logical thinking ability and habits in mathematics.
Everyone's thinking ability is different, and the thinking habits are also different, some students are more inclined to image and perceptual thinking, and are relatively weak in mathematical numerical and logical thinking. Such students will not have much problem with the basic knowledge and basic understanding of mathematics, but they may find it difficult to deal with some relatively difficult problems.
Original = (1 10-1 11) + (1 11-1 12) + (1 12-1 13) +1 15-1 16) = 1 10-1 16 = 3 80, and the opposite number is -3 80It's the answer.
Let x=a1+a2+.a2008+a2009.
p=(x-a2009)(x-a1) >>>More
Equality relationship: number of boys * 3 = number of girls * 7 >>>More
Mathematics is the best of all subjects.
My method is to listen carefully in class, even if you don't understand it, you have to listen carefully and memorize carefully. If you don't understand, you ask, ask the teacher to ask your classmates, when you don't understand some related questions, let them tell you by the way, I think they are willing to help you solve it, don't care about face, the problem is simple and don't understand. >>>More
In fact, this is the problem of several important points in the triangle. >>>More
