How to improve math to the first or second place in the grade? There is a bounty.

It's simple, but it takes your perseverance:

I don't know how your exams are there, but in short, our exams here are very simple in the front and difficult in the back. So we are all focusing on difficult problems, such as the Olympiad problems.

Read more textbook concepts, learn to be flexible and familiar with the use, in short, you must read the textbook, you can't do it without reading, I have a deep understanding.

I recommend reading less reference books and the like, of course, if you have time, it doesn't hurt to read them, but in my experience, many reference books only summarize the textbooks, so you might as well read the textbooks directly.

It's the third year of junior high school, play less on the computer, watch less TV, brother, I'm also here!

That's all, in short, that's how my experience is, I hope you are satisfied.

If you do well in your class, try to grow your way up. If you have any questions, ask the teacher in your age. Then do more questions.

Although I don't quite understand why I care so much about rankings. But the topic you insist on caring about is also good. Of course.

It also supports you to find class newspapers outside of class. Enroll in that kind of famous teacher class. Specializing in teaching elite students.

Discuss all the questions you couldn't do on the exam. Then if you do all the questions that you can't do during the exam. You're number one.

Hehe.

How to put it, you try to be a little less sloppy every time.

First, and third, is there really a difference in strength?

Why is it always the first, this is something other than the level of strength, mentality or something.

You can also be the first to overcome the psychological factors, and there is no need to be stubborn, do not be demanding, relax and cope, there will be progress.

Of course, in fact, there are always some people with superior strength, and there are always differences between people, but according to what you said, there are not such people in your class.

Send you a word, learning is to work hard and work hard, seriously and seriously!!

I feel the same way, but I've solved it successfully, let me tell you, find the teacher first, talk to the teacher, listen to the teacher's opinion, and then change to your own learning method, the premise of sloppiness, there are also reasons for not being familiar with the question type, so you have to do the wrong question type several times every time.

When you do the questions, you should make a good list of formulas, be careful in every step, and be careful in the process calculation, so that the learning in the third and fourth grades will not be too difficult - if you do homework to cope with official affairs and even make a mistake in calculation, it will be much more difficult to change bad habits in the future.

Do more practice questions and summarize your own methods for each type of problem (it seems a bit difficult for your age). At this time, you mainly make sure that you don't make mistakes, right? It shouldn't be very demanding.

Cultivate children's interest, usually let children do more practical application problems, the effect must be good!

The third grade is difficult, so go and learn the second grade again.

（1）∵(a^1/3±b^1/3)^3=a±3a^2/3*b^1/3+2a^1/3*b^2/3±b

x±y=(a^1/3±b^1/3)^3

x+y)^2/3+(x-y)^2/3

a^1/3+b^1/3)^2+(a^1/3-b^1/3)^2

2(a^2/3+b^2/3)

2) Substituting a=2b+2 into the equation ab+ 3 2c 2+1 4=0.

3 2c 2=-2(b 2 + 2 2b+1 8)=-2(b + 2 4) 2

i.e. c 2 = -4 3 * (b + 2 4) 2

Because the square is a non-negative number, c=0, b=- 2 4, a= 2 2

bc/a=0

3) a+b+c) 3] 2 [a 2+b 2+c 2] 3 and take the equal sign if and only if a=b=c.

4 3=[(a+b+c) 3] 2 [a 2+b 2+c 2] 3=4 3

a=b=c=2√3/3

a-2b+c=0 means that the conclusion is true.

4) Is the title correct? No.

5）[√n+1）-√n]-[n-√(n-1)]=√(n+1)+√n-1)-2√n

where [ (n+1)+ n-1)] 2=2n+2 (n2-1)<4n

√(n+1)+√n-1)]^2-(2√n)^2<0

（n+1）-√n<√n-√(n-1)

You're a parent, right?

First of all, I want to say that I am already a long way from first grade. But I have a good memory. I remember that at that time, it was mainly a quick calculation. That's how it should be.

Learning is all the same, not in the difficulty of what is learned, but in the interest and method. Especially the first grade child should pay more attention to making him happy to learn and not pushing him. Digital games and rewards are necessary.

I can't say how to do it, only you know your child, so I hope you will explore ways to open his interest. Don't rush it, because math in elementary school, to be honest, is a basic knowledge that can be understood naturally, and there is no need to be overly demanding. As for the performance of higher education, I think that only the content after the second year of junior high school has a decisive role in the 12 years of study and life.

Of course, the rest of the knowledge is not important, and it is basically something that everyone can easily grasp.

Mathematics in Primary 1??

If you are a parent, let your child have a good time, develop their IQ in play, and find their own interests;

If you're that student, don't worry, math in the first grade of primary school is not math, so what does it matter if you learn well or not? At this time, the score is not high, it does not mean that you will not be Hua Luogeng's in the future Don't worry, the scores are all floating clouds......

It could be that he is not interested in learning and can make him play middle school. You can ask him to make calculations with small sticks or matches.

You can also do some simple addition and subtraction with its favorite toys.

The score is related to the following factors: the child's level of learning, the difficulty of the questions, the child's state of mind, the child's physical condition, and the consistency of what is being learned with the test questions.

Children in the first grade of primary school should first pay attention to cultivating children's interest in learning and establish good study habits and learning methods from an early age.

A child's academic performance is related to the following factors: large class sizes at school, home education, and the child's attitude towards learning.

To improve your child's academic performance, you must first find out what is causing your child's grades to decline or stagnate, and then you can prescribe the right treatment.

I don't need to improve my elementary school math score by more than 30 points, I still focus on high school, and I still focus on college.

It made him interested in many aspects and think about problems from different perspectives. Let him have a clear sense of time, when he should do something, and start with forming habits. Then talk about the questions you don't understand, and then expand on them in depth.

Some rote memorization things need to be memorized, and they can also be memorized. The first grade of elementary school is very simple, so let's develop a good mindset first.

The thinking of students in the first grade of primary school is not yet mature, so it is recommended that you do not worry, communicate with your children more, ask math problems in life, and improve your children's mathematical perception and interest. In your spare time, you can play some math games with your child.

First-graders only know how to play and watch cartoons, so why not add these good conditions to their learning! Wouldn't that be better! You can't isolate math from life for them, and my little niece also connected things in life to math every time she taught her math in first grade, so he was always interested.

The focus is on the combination of images and shapes, and through the image of graphics and stories, students are interested in learning.

It's only the first grade, so let him prepare the arithmetic card

Pay attention to the combination of numbers and shapes... Strengthen the cultivation of rational thinking...

From the first grade, you should practice addition and subtraction, and it is best to blurt it out.

In the second grade, practice multiplication and division.

Learn the sixteen-character mantra of mathematics well, "preview before class, review after class, refine and practice, summarize and improve." "Hope it helps.

Don't miss any of the questions, such as what you went out to buy today, do the math, it's good for right brain development, and pay attention to the basics.

Do more practice, memorize mantras, practice makes perfect.

Ask your children more in life, for example, when you are riding a car, you see a 3-way bus and ask 3+2=

First of all, don't let your child take a mobile phone or calculate his calculations, do more practice problems in his spare time, check the child's scratch paper after completing his homework, see if the writing is correct, whether the attitude is serious, and the wrong calculations should be recorded in a wrong question book and checked regularly.

The third grade of primary school is the time to lay the foundation of mathematics, you should take it seriously, first of all, listen carefully in class, memorize theorems, do homework, and complete the exercises carefully, your grades can definitely be improved, it is best to cultivate an interest in mathematics, if you are interested, you will naturally improve your grades, pay attention to it when you take the exam, or participate in make-up classes, it will also help you improve your grades. It is mathematics as long as you are willing to use your brain and be serious, it will not be difficult Do more exercises, understand the various types and ideas of the body, and improve efficiency.

To certify the lectures, take more notes, read more materials, remember the key formulas, and lay a good foundation for the future!!

Why is it that all kinds of tutoring classes for children have no obvious effect? Ignoring the diagnosis just because of blind tutoring, the content of tutoring may not be what he needs.

The most important thing in mathematics is to master the basic knowledge, and the accuracy of the calculation will be improved a lot, for example: filling in the blanks in mathematics and judging individual problems need to fill in the blanks after calculation, and choice. Oral calculation, vertical calculation, estimation, recursive equation calculation; The subsequent columnar calculations and problem solving need to be calculated accurately to score points.

Grade 3 mathematics is mainly about improving children's problem-solving ability.

The basics of addition, subtraction, multiplication and division should have been learned in the first and second grades.

To enhance children's basic knowledge, such as some formulas and concepts, in addition to memorizing the literal, they should also be put into the practical application of the problem.

Asking more questions is the only way you can do it.

The formula is not memorized by rote, but to understand why the formula is the way it is, and the same is true for the theorem, which needs to be understood, but it is said that the theorem in elementary school will be written in the original exam questions, so you still have to memorize it, and you will not take the test like this in junior high school.

Memorize the basics, plus understand. I took three years of math in the first half of the year.

Do more exercises, find more ways, and get along together.

Do more practical questions to improve your comprehension skills.

For mathematics, whether it is elementary school, junior high school, high school, university or graduate school entrance examination, it is the key to do more problems and find more loopholes in your own existence!

Give him more encouragement to make him feel that math is actually very simple, and don't pay too much attention to the scores, pay attention to the cause of the mistake, and figure it out.

The class should be active, and students should be encouraged or rewarded to increase their interest (*hee-hee......

Teaching and jokes in mathematics attract students' affection.

I remember I used to hate math.

But when I got to middle school, my math teacher was very optimistic about me.

So my interest in mathematics grew.

The key is to look at the teacher.

Interest is a real headache. There are both rewards and punishments, and you will only be interested if you know more about mathematics.
