In the second year of junior high school, I just didn t know how to learn math and didn t make any p

First of all, we must figure out whether it is the second year of junior high school, or the previous one, mathematics is one link after another.

The second is to figure out which piece will not be, why it will not, is it carelessness, is it not mastered knowledge or cannot be used flexibly?

If you fail, it means that the situation is quite serious, so start from the basics and practice more. Mathematics still needs to be done, starting from the most basic, to ensure that the test questions are good.

I hope the above personal impressions are helpful.

Don't be discouraged. Mathematics is based on doing more problems on a regular basis, I am not bad at mathematics, I also have tutoring, I want to strengthen my foundation more! Mathematics is changed by formulas, familiar with formulas, and if you do more problems, your grades will naturally improve.

Hello. Do more math and do more practice problems about what you are learning now, do more problems, improve your efficiency in doing problems, and cultivate your problem-solving ability well!! Also, listen carefully and don't desert, and complete your homework carefully, I think it should be useful!! Wish.

It makes sense on the first floor, I'm a science student. My English has always been bad, but I was at the top of my class in every test because math helped me get a lot of points. So I guess I know a little bit about math.

Mathematics is about solving more problems, and in addition, I recommend that you buy a book of thematic exercises, so that you will find some patterns in the process of solving the same type of problems in a row. In fact, not only mathematics, but also many science subjects (such as physics) must be solved.

Hello child, I am a parent of a child's child, the child is also in the second year of junior high school, read your post, I know you must feel very anxious, what I want to tell you is, don't give up on yourself, everything is still too late in the second year of junior high school, the teacher will have a systematic review in the third year of junior high school, and will review from the beginning of junior high school, of course, you also have to put in a certain amount of effort in the summer vacation, but I think that the autonomy of your own review may be very poor, and it is not easy to find the right way to learn, I suggest that you find a one-on-one tutor and lay a good foundation first, which is very critical for the second year of junior high school, otherwise there will be no time to lay a solid foundation for the high-intensity review in the third year of junior high school. Below, taking language as an example, I will talk about my child's situation, I hope it can help you:

My child's language has not been very good since he was a child, and he has been enrolled in classes since he was a child, and he has also gone to school, but there are many people in the classroom, and there are not too many opportunities to get teacher guidance, and my child has a poor foundation, and he does not like to learn even more when he compares with his classmates, and he does not want to say anything after class every day. At that time, I was also very worried, how could my children learn Chinese well? We searched for good language tutoring classes on the Internet and found two or three, and the children didn't want to go as soon as they heard that it was a class format.

Later, the child's classmates recommended Pingmeng to the child, saying that it was one-on-one personalized tutoring, which had a good effect and was good at cultivating students' independent learning ability. I'll just enroll my child in a class. Later, in Mr. Zhou's tutoring class, the teacher first analyzed the reasons for my child's poor Chinese, and also analyzed the child's composition level and reading level, etc., and I felt that what the teacher said made sense.

Teacher Zhou has formulated a detailed tutoring plan based on my child's Chinese foundation, and I feel that the child's progress is still relatively comparative.

However, in the case of finding a tutor or tutoring class, you must ask others carefully and discuss with your parents, and it is best to choose a tutor with good teachers and responsible for students. I wish you a good foundation and improved grades.

The math in the second year of junior high school is not very difficult, the main thing is that you study hard, do more exercises and familiarize yourself with the concepts in the books, I believe it will work, you can give it a try!

First of all, you have to read the book, understand the definition in the book, memorize the formulas in the book to the extent that you are ripe, and there are example questions, you must understand each example problem, and then find some exercises to do it appropriately, you don't need too much, but you must ensure that you will do it, and it is more than enough to do these in this holiday. If you are not very good at mathematics in the first year of junior high school, then you need to read the book of the first year of junior high school first, and you don't need to be very detailed, because the foundation of mathematics knowledge in the first year of junior high school is not very difficult, just read it roughly, and the formula will be used, and then start to read the book of the second year of junior high school in the above method.

Preview is the process of actively acquiring new knowledge of junior high school mathematics, which helps to mobilize the initiative of learning, and it is an important means to acquire mathematical knowledge by carefully reading the textbook and developing the habit of active preview before the new knowledge is explained. Therefore, it is necessary to pay attention to cultivating self-learning ability and learning to read. For example, when studying the example problem on your own, you should find out what the example question is about, what conditions it tells, what it seeks, how it is answered in the book, why it is answered this way, whether there is a new solution, and what are the steps to solve the problem.

Chapters on elementary and second geometry like "Pythagorean Theorem", "Congruent Triangle", "Centrally Symmetric Figures", etc.; The first thing to do is to memorize and master all the theorems, and properties.

Then, in the actual proof question, you need to grasp the stem conditions (and at the same time look for the hidden information of the question stem), and seek the answer step by step through the known conditions, thinking about the missing conditions and the question stem questions. Proof question types are a step-by-step process of reasoning. Geometry examples can be significantly improved by brushing the typical examples of related geometry models.

Note: In geometry examples, it is very important to draw a standard ruler and gauge, and the reasonable marking of the stem conditions in the geometric figure can achieve twice the result with half the effort.

If you can't keep up with the math in the second year of junior high school, you will have to memorize more basic knowledge. In the process of learning in the second year of junior high school, mathematics is very important, and everyone should slowly keep up with the pace of the teacher. In the evening self-study.

, spend more time on mathematics, and if you encounter this kind of knowledge that you don't understand, you should ask the teacher in time. <>

Mathematics in junior high school is much deeper in difficulty and breadth than mathematics in elementary school. Many students' grades plummeted after entering junior high school because they did not develop good study habits. In elementary school, because the knowledge is relatively simple, you only need to follow the teacher carefully, so that you can achieve an excellent grade.

However, when I was in junior high school, I was more concerned about my ability to learn on my own, so I could preview what the teacher would explain before class every day. Don't play all the time after class, you can carefully recall what you have gained in this class. <>

When I was in junior high school, I scored 120 in math and was a main subject. If your math performance is not satisfactory, I believe it will affect the overall performance, and it is recommended that you sort out the problems and mistakes encountered in the usual learning process, and be sure to classify and sort them out. Wait until you take it out before each exam, and if you already have this knowledge, you can ignore it.

If you still don't understand the knowledge, you can ask your classmates for advice. <>

If you can't keep up at this time, it will be very difficult to keep up in the future. Sometimes learning is like snowballing.

The more questions you have, the bigger the snowball will be. Therefore, if you encounter knowledge that you don't understand, you should immediately seek help from your teacher, and don't feel embarrassed. You can understand this knowledge point, and then string other knowledge points together to form a complete knowledge structure and system.

You can make yourself more active and take the initiative to use your brain to absorb knowledge.

I think the second year of junior high school is a critical period, and at this time, I still have to brush up on the questions, and explain the key question types on the weekend. Review and then preview every week. Just stick to it for a month or two.

At this time, you should know that you have not learned well and then supplement it in time, and if you encounter more problems, you should also ask the teacher in time, and you can also find a better tutoring class to learn.

Then you should first learn some basic mathematical knowledge, do some basic problems, and slowly progress to more difficult problems.

The maximum side length in a frame made of 160 cm is three times the width of the frame, width: 160 [(3+1)*2]=20

Length: 20*3=60

The maximum area is 20*60=1200, less than 1323. So, there is no such rectangular frame.
