How to learn Mathematics for Junior Secondary 2

I'm also in my second year of junior high school.

It's pretty much the same as you learned.

Functions can be hard to understand when you first get started.

It takes three consecutive lessons to understand it.

The method given to you is useful for me.

Hope it helps.

1. Don't rush to write notes during class, it will be more important to understand mathematics.

2. Don't feel embarrassed to ask questions to teachers and classmates with good grades, as long as you don't figure it out, you must be responsible for yourself.

3. Insist on not copying homework, not checking questions at night, and being diligent in asking teachers, and your grades will improve by leaps and bounds.

4. Follow your time: Don't force yourself to go to cram school or do extracurricular problems, leave time to review and organize.

Functions in junior high school will be simpler. Mainly primary and quadratic functions.

The content of the primary function is generally relatively simple, and the problem solving skills are mainly to set the analytic formula of the function, and then find the corresponding conditions according to the design.

It is recommended to preview in advance, and then remember that y=kx+b (k is not equal to 0) is in k>0, b>0; k>0,b<0; k<0,b>0;k<0,b<0.

Quadratic functions are a bit more difficult: y=ax 2+bx+c (a is not equal to 0).

It is recommended to start with the image, pay attention to the case of a>0 and a<0, and what is the difference between the axis of symmetry x=-b 2a on the left and right side of the y-axis.

According to the needs of the problem, you can flexibly choose the vertex formula y=a(x-m) 2+n, the two-point formula y=a(x-x1)(x-x2), and the general formula y=ax 2+bx+c solution.

Function function is naturally the most important image, and the big questions in the exam are basically a synthesis of function + geometry.

Therefore, it is necessary to be proficient in function images, function properties, and then brush up on the ......

ps: It is recommended to learn the system of unary quadratic equations + unary quadratic equations first, and observe the relationship between the equation and the image after mastering it, which will have a lot of gains.

After class, do more questions about functions, practice makes perfect.

Function, this simple question sea tactic, all question types will be able to do anything.

Children's shoes Since you are a student, you should not use the Internet from Monday to Friday. Your grades go up. I usually have nothing to do more questions, and I ask the teacher questions. The main thing is that you must be very serious in class, and if you don't understand something, you must ask.

Preview before class. Review after class.

Do more exercises. I don't know what I teach.

The main thing is that the exam is careful, and if you can't do it, you can buy some reference books by yourself.

If you don't know, you can ask the teacher.

Answer: To learn mathematics well, you must have a strong interest in learning, necessary learning ability, scientific learning methods and good study habits.

Mathematics is the study of numbers and shapes. The difficulty in the algebra part of mathematics in the second year of junior high school is functions, and the first thing to understand is the concept of functions.

What is a function?

For example, if the father's age is y, the son's age is x, and the father is 25 years older than the son, the relationship between their ages can be written, y=x+25

These two people are father and son, the son calls the father father, the two numbers y and x are functions, and y is called a function, i.e., y is a function of x.

Its essence is that y uniquely corresponds to x

That is, for every value of x, there is always a value of y corresponding to it.

In the father-son relationship, for every son, there is always a father who corresponds to him.

Generate interest in learning.

Mathematics in the second year of junior high school should not be difficult for middle school students, the learning content only includes algebra and plane geometry, and has not yet learned trigonometry and solid geometry, so as long as you work hard, it is not difficult to learn at all. I wish you success!

In normal times, you only have to do more questions While doing the questions, you should pay attention to sorting out the knowledge network After completing a question, think about whether there is any other way It is recommended not to do too many questions before the exam You can do a mathematical storm in your mind about 1 hour before the exam (that is, thinking about some formulas and theorems) to bring out the feeling of mathematics Handy during the exam.

The most important thing to learn math in junior high school is to brush up on the questions, practice makes perfect!

1.Listen carefully in class 2Review carefully after class 3Lots of questions.

Math. If you want to prepare a question book, then review it more, and read it before the exam, which can be regarded as review.

It's very effective, there are many questions in mathematics that are not difficult, but there are many small pitfalls, and I understand it more clearly in the third year of junior high school.

Hey. Let's do our best.

First figure out the difficult problems you don't understand in the second year of junior high school, and then do more top-notch questions in the future.

Preview in advance, listen carefully in class, review after class, do more questions, and don't just ask.

Do more questions, think more, and draw inferences.

Hello, Mathematics in the second year of junior high school is actually not difficult, but it is more theoretical, don't be afraid of mathematics, and don't be too nervous. As long as you look at the score, you can do it, otherwise you will be too nervous and you will not be able to review. If you are nervous, you will be afraid, math is not difficult, so don't be nervous.

I would like to talk about the learning methods of mathematics in the second year of junior high school, I hope it will be helpful to you.

First of all, be confident. Many scientific studies have proved that human potential is great, but most people do not effectively develop this potential, among which human self-confidence is a very important aspect. Whatever you do, whenever and wherever you do, with this self-confidence, you have a belief that you will win, and it will enable you to quickly get rid of the shadow of failure.

On the contrary, if a person loses his self-confidence, then he will achieve nothing and can easily fall into eternal inferiority. Secondly, with scientific learning methods, you can achieve twice the result with half the effort in learning. This is the method that Mr. Liu told me to improve efficiency:

There are learning links, learning attitudes, and learning methods. As long as you change your studies from now on, and you study hard, of course, it will be simple, and your grades will improve. Everyone's foundation is different, and their learning attitude is different, so the methods to be adopted are also different.

In order to learn well, you must find a learning method that suits you, and you must choose a suitable method according to your own characteristics. You can make progress. The method of learning should be "a hundred schools of thought contending" and "a hundred flowers blooming".

The last thing I would add is to be interested, secondly to be determined, and again to be patient. Finally, study carefully. Start with the basics – familiarize yourself with the skills – apply.

It must have been practiced countless times. Understand the characteristics of the subject, memorize the formulas, think more, dig more and do more questions, there is never a shortcut to learning, only practice, practice, and practice.

Hope my answer is helpful to you.

Junior high school math is very simple. Did you understand all the example questions that the teacher said in class, and did you take notes? Take notes, then look at them from time to time and memorize the solution to the example problems.

There is no problem in coping with the exam. Of course, you have to do your homework carefully. After thinking about it, I still don't understand, and then ask my teacher or classmates.

I don't think I need to make up the lessons. The key is to master the problem-solving skills and methods by yourself. When you close your eyes, you can recall what knowledge points and formulas are mentioned in the book.

Be able to understand the intention of the questioner. See through the knowledge points of the questions.

If you want to put yourself into it, you will be interested, you will love to learn, and you can learn well

The key is to be efficient in class, to concentrate on listening, and not to use after-class time to make up for the content of the class, which is very inefficient and not cost-effective.

Secondly, copying homework must be controlled. When I was in the second year of junior high school, there was a principle that I would do it when I saw it, and I would not do it; If you think about it for a while, you can do it with your heart, and often you have to do it in several ways; If you understand a part, ask the teacher and classmates to understand it, and review it often; Not at all, don't spend too much time. But there is a premise for these, generally speaking, it will not be a difficult competition question at all, and this kind of question can be abandoned; If you don't know the point of the exam at all, you must understand it.

Also, this distinction does not apply to the third year of junior high school, which you have to do regardless of whether you think you can do it or not. Copying homework is actually the most unwise behavior, sometimes there is no way to do this, but you must make up for it afterwards, you must understand that this behavior is fundamentally a waste of time, when it is too simple, it is better to save time than copying.

Finally, some advice: it is best to prepare the correction books for each subject by yourself, do not pay too much attention to the form, focus on the essence of the problem, and understand why you are wrong. Correction books should be taken out often and redone.

Understand that if you don't get the answer right, or if you don't correct the answer, you're basically doing it in vain.

Listen carefully, do more practice questions, organize the wrong questions in a book, and read more when you have time, and strive not to make mistakes next time you encounter similar questions. Do a good job of pre-study (mark what you don't know, and focus on listening to the marked places when the teacher lectures). Do a good job of revision.

If you don't understand the questions, ask the teachers and classmates in time.

Happy learning!

It mainly depends on talent, some people just can understand it after listening to it once, and some people just listen to it many times, and he still doesn't understand if he doesn't understand. Talent is very important, it will be difficult to learn without talent, but it does not mean that this is completely abandoned, and some things should still be able to understand a little bit after reading too much. It's just that I don't have the talent and want to be a leader in this subject, which can be said to be almost delusional.

Mathematics is one of the compulsory subjects, and the cultivation of mathematical ability is mainly carried out in the classroom, so it is necessary to pay attention to the learning efficiency in the classroom and seek the correct learning method. During class, you should closely follow the teacher's ideas, actively think about the following steps, and compare your own problem-solving ideas with what the teacher said. In particular, it is necessary to grasp the learning of basic knowledge and basic skills, and review them in a timely manner after class without leaving any doubts. First of all, it is necessary to recall the knowledge points taught by the teacher before doing various exercises, correctly grasp the reasoning process of various formulas, and try to recall as much as possible without using the act of turning the book immediately if it is not clear. Conscientiously and independently complete homework, diligent thinking, in a sense, should not cause a learning style that does not understand that is asked, for some topics due to their own unclear thinking, difficult to solve for a while, should let yourself calm down and seriously analyze the topic, try to solve it yourself.

In each stage of learning, it is necessary to sort out and summarize the points, lines, and surfaces of knowledge to combine and weave them into a knowledge network and incorporate them into their own knowledge system. If you want to learn mathematics well, it is inevitable to do more problems, and you must be familiar with the solution ideas of various types of questions. At the beginning, you should start with the basic questions, take the exercises in the textbook as the standard, practice repeatedly to lay a good foundation, and then find some extracurricular exercises to help you develop ideas, improve your analysis and solving skills, and master the general rules of problem solving.

For some easy-to-make questions, you can prepare a set of mistakes, write out your own solution ideas and the correct solution process, and compare the two to find out your mistakes, so as to correct them in time. In normal times, it is necessary to develop good problem-solving habits. Let your energy be highly concentrated, so that your brain is excited, your mind is quick, you can get into the best shape, and you can use it freely in exams.

Practice has proved that when it comes to critical times, the problem-solving habits you show are no different from your usual practice.

In fact, there is no need to say this method and that method in a complicated way, there are many places to use the brain in science things, and some people may think that this is difficult or something. In fact, this kind of difficulty should be able to be adapted, and there are conditions to complete it.

What's the point? Personally, I think it's interest.

You will find that many people who are good at mathematics are very willing to challenge the difficulty, they find it interesting, fun and challenging to be willing to learn mathematics, compared to some people who do not listen well in class and go to cram school to make up for it and then improve their ability to excel in the exam.

Science is not the same as other subjects. Most subjects have a lot to memorize, science, especially mathematics, there are few things to remember, the focus is on application, I personally do not recommend everyone to rote memorization of the teacher's knowledge points, you will find that you remember those things or will not use them, and it is difficult to think of a certain knowledge point when you see the question. The focus is on doing the questions.

If you feel that you can't remember the knowledge points of the teacher during class, you can make notes and do it in the notebook, and then don't memorize him, choose a few questions in the workbook when you have time, and then think deeply about the knowledge points little by little, don't think that your foundation is poor, and there are very few basic things in mathematics, mainly to use. As long as you use your own ability to complete a problem, you will basically have no problem, and if you follow this method for a long time, you will find that you will have a sense of accomplishment when you solve a problem, and slowly your interest in mathematics will be successfully cultivated, and your interest will be very helpful to you in thinking about problems in the future.

Revision and pre-study are routine learning methods that don't necessarily work for science subjects such as math. Not to mention the preview, it is best not to try for those with poor foundation, and when you have a good foundation, the preview will be helpful to your efficiency the next day. Review for people with a good foundation sometimes find that it is completely unnecessary, if you can understand what you say in class, I don't need to review the science things, it's really better to do the questions if you're idle, and for those with poor foundation, you can refer to the method in the last key point I wrote, cultivate interest, and it's equivalent to reviewing again.

In short, interest is the best teacher, and science must be easy and enjoyable. The above are all my manual type, belong to my experience, I hope the landlord adopts!
