How can a junior high school student improve math in a week?

Friend, I'm about to enter my first year of high school, and I'm good at math, physics, and chemistry, but not particularly good at Chinese and English. Mathematics is not like language, there is only one answer, there will be no other answers. You still have a week, I don't agree with the above people's statement, because if you are still doing in-class exercises recently, then you will develop a kind of "dependence" psychology, that is, "memorize questions" (I used to be like this in elementary school), because sometimes you will get exactly the same questions in class, and then you will memorize a few questions before the exam, which is not conducive to your future junior high school studies, so now the most important thing for you is to do more extracurricular exercises (simpler, It is conducive to adjusting your mentality), memorize the concepts in the book (this is very important, don't take it as a deaf ear), in the examination room, do the simple ones first, leave the difficult problems to the end, and break them one by one, reading the questions is also very important, don't ignore the conditions in any of the questions, 80% of the conditions he gives you will be useful, junior high school will not be like primary school, give some useless conditions, break through a point is a point, it really won't do, it doesn't matter, 100% accuracy is unrealistic, of course, you don't give up easily.

Having said that, I also want to tell you that you are a girl, right? Studying science is a bit difficult for girls, math is not something that can be learned in a day or two, even if you do well in the exam this time, don't play in the summer vacation, practice more questions, understand? Mathematics is to do more questions and master the method of doing problems (do not memorize questions, memorize answers!!

That's it. You want to summarize the method, I'm sorry, I've graduated from junior high school, and I haven't done the chapter of real numbers for a long time, in fact, this chapter is very simple, just remember: open the square, take the positive and negative; The one with the "+" sign before the root sign is the square root of arithmetic, and the one without the positive sign is the square root, and the plus and minus signs should be taken (remember that there are two answers), and the number of squares is greater than or equal to 0; I don't seem to have much talk about this section with a calculator (I'm from Chengdu), this chapter is nothing rare, be careful, and pay attention to the operation symbols.

Finally, good luck!

I'm in my third year of junior high school this year, and I'm good at science, so I'm a good person. To share some experience with you, very practical, it depends on whether you do it or not: 1 Find a generous time to sort out the wrong questions in the exercise books and test papers you have done before and then do it aside, if you can't quickly consult the teacher, figure it out until 2 insist on making a review coupon every day this week, and if you can't, quickly ask the teacher 3 Establish confidence in the exam, believe that you will be able to do it, and recall your usual mistakes during the exam, and do not panic...

Do math frantically, do math when you have time, understand the problems you have done, and make inductions.

Get enough sleep.

Adequate nutritional supplementation.

Buddhism also needs to know how to hold, and the top priority is to understand the questions you have done before, and you will feel much more confident after you are done.

I'm the same age as you, and I'm the first in mathematics in our whole grade, not to mention much, your time is very short, and the best way is to read all the examples on math numbers, and if the concepts are not familiar, look at them.

If you have time, read the questions that you personally think are easy to take (questions that appear several times in normal times and typical problems).

Don't read the questions you think you understand.

I wish you and I all the best in the exams.

Ask me any questions

It's useless, take the test well when you take the exam, calm down and try your best, Mom and Dad won't blame you.

The main part of the class is to listen to the example problems taught by the teacher and the knowledge points that are diverged.

I also have to keep sorting out my mistakes. Ask the teacher (at least 2-3 weeks).

It's impossible, hold Buddhism temporarily, unless you are lucky enough to hold the Buddha's head' is true.

Set aside 30 minutes a day to read the sample problems in the book.

Set aside 15 minutes to make and buy math study materials.

Wake up in the morning and memorize common math formulas.

If there is anything you don't understand, ask the teacher and classmates.

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

I'm just like you, math is not very good, but you have to like math, like my brother, his math is among the best, my grades have to be scored in the liberal arts, we all have to work hard, come on!!Remember: memorize more formulas and practice more questions.

You need to have an interest in mathematics first.

Listen carefully to the knowledge points taught by the teacher in class.

Do more practice questions on a regular basis.

Guaranteed to turn your stupid into a genius.

That's a quote from our math teacher).

ps: I'm also in my first year of junior high school.

Do more practice questions.

The most important thing is to understand the practice.

In fact. Going to tutoring is also a shortcut.

First like your math teacher, then slowly get back to liking math! I'm just a math teacher in a small town! The students love me and love my classes! The teaching results are not bad now!

Do more questions. Reading.

Don't study anything, focus on math.

Memorize more formulas and practice more questions.

Go through the exercises and examples in the book.

Unless you are God! It's better to learn steadily, you still have time.

It's impossible to hold Buddhism temporarily, unless you are lucky enough to hold the Buddha's head.

How to learn mathematics in the first year of junior high school and how to improve it? Probably a lot of students and parents are bothered! In fact, this question is also very simple, it is to work hard, work hard, and lay a good foundation.

1.Holistic thinking.

Starting from the whole of the problem, highlight the analysis and transformation of the overall structure of the problem, discover the overall structural characteristics of the problem, be good at using the "integrated" vision, regard certain formulas or graphics as a whole, grasp the relationship between them, and deal with the whole in a purposeful and conscious manner. The holistic thinking method has been widely used in the simplification and evaluation of algebraic formulas, the dismantling of equations (groups), geometric solving, and factorization.

2.It is necessary to pay close attention to the standardized training of problem-solving steps.

Only by starting from the standardization of problem-solving steps and formats, strict requirements and repeated training, can students overcome the problems of perfunctory, so-so and irresponsible learning. Long-term persistence in training and strict requirements will inevitably enable students to develop good study habits and enhance their thinking ability.

3.It is necessary to pay close attention to the training of numeracy ability and strengthen the cultivation of serious habits.

The problem of poor calculation accuracy of students is not only caused by problems in the grasp and application of knowledge, but also caused by some bad habits. In order to prevent the occurrence of the above-mentioned phenomena, we should first grasp the attitude and enable students to develop good study habits. In my 7th grade mathematics teaching, I used the mixed operation of rational numbers to strengthen the training of study habits, and I received good results.

In addition, it is necessary to strengthen the examination. Whether students are fast or not and accurate in doing questions depends on the means of strengthening inspection and evaluation. Students should also be encouraged to look for reasons for mistakes.

Errors in students' calculations are not only the cause of poor mastery of basic knowledge, but also the cause of bad habits. Teachers should help students to find out carefully, classify them, correct them in a timely manner, and let students summarize themselves. In the long run, this will be of great benefit to the formation of students' serious habits of learning and the cultivation of a rigorous attitude towards learning.

4.Break through layer by layer.

Especially for students with poor foundation, they must not be in a hurry to break through the problems, start from the most basic topics, be familiar with the definitions of various formulas, understand the collective steps of different types of problems, and first do a good job of the simplest problems until there is no problem with all the simple and basic problems, and gradually transition from simple to difficult problems when trying to solve the problems of medium difficulty, so that they can have a sense of accomplishment when solving the mathematics problems that they can't solve, so as to improve their confidence in mathematics learning.

Go to work and study hard, don't run away and doze off.

1.Perseverance, confidence and persistence are the prerequisites for being able to turn around.

3.Rebuild the basics, if the basic knowledge of mathematics is now almost 0.

4.If we want to change the status quo of low scores, we must learn mathematics from scratch and rebuild the foundation of mathematics.

5.Consolidate and improve, if the previous foundation is done, we must consolidate and improve, do more practice.

1.Starting from k1=0, you take two jumps as a group to find the pattern, you will find that the total number of jumps to the left is 2 more than the total number of jumps to the right, from k1 to k3 is two steps to the left than k0, and k5 must also be two steps to the left than k3. If you count how many sets of K49 jumped twice, you can know that it has taken a few two steps to the left, and K49 should have jumped exactly 24 and moved 48 steps to the left, which is the position of 48 units to the left of K1.

k1=0, so k49=-48

Explain that a total of 49 jumps, the first time to jump one step, after each jump two more steps, the last time should have jumped 2*49-1 steps, 1 + 3 + 5 + ...2*49-1）=（1+97）*24+49=2401（s）

It's 492Add from 1 to 97, multiply the first term by the number of terms and divide by 2 to get 4753

First of all, as a study committee, I believe that you must have excellent academic performance, and not only that, but you can also find out your shortcomings and use the Internet to seek help, which is good.

First of all, you have to think quietly about what is the reason why you can't get your math grades up, whether you don't understand what the teacher says in class, or because the foundation of mathematics is not solid, or because you don't review and consolidate in time after a section, or because the learning method is wrong, and so on. These are all things you should reflect on.

Secondly, you must know that "freezing three feet is not a day's cold", the same is true for learning, you must always maintain a motivated mentality, and you can't doubt your ability because you have been ruthless in mathematics for a period of time, but your grades have not improved, which is only harmful and not beneficial.

Let me talk about my views on the study of mathematics. "Mathematics is the queen of natural science", you can imagine how important it is to learn mathematics well. Mathematics is not like other sciences, it has strict logic, that is, the learning of mathematics is linked one by one, which requires you to master each link well, otherwise it will affect your future learning, which is not only mathematics.

The mastery of mathematical theorems and formulas also requires you to have a certain amount of exercises, that is, you can't learn mathematics well just by looking at the textbook without doing a certain amount of exercises.

Finally, I hope you don't give up, study mathematics seriously, persistence is victory, and your grades will definitely improve!

The system of ternary one-time equations, generally requires three to solve, but it can be combined with other conditions, it is not difficult, learn mathematics to do a good job of preview and review, listen carefully when speaking, do not understand quickly to understand, and then practice, you can first look at the example problems, read a few more and then follow the practice, it is not difficult to improve, I hope it can help you.

Do more practice, that's how I passed the high school entrance examination.
