Write an essay of about 400 words on the topic of How to learn junior high school mathematics well

Learning mathematics requires not only a strong desire and enthusiasm for learning, but also a scientific learning method in order to learn mathematics well. From the analytic mathematics learning activities, it can be seen that the learning method is not only restricted by classroom teaching, but also has some characteristics of its own. Therefore, on the one hand, we propose learning methods that are compatible with classroom teaching, and on the other hand, we summarize some special learning methods according to the characteristics of mathematics learning.

1. Methods of previewing, listening, reviewing, and homework.

The learning methods that are compatible with the teaching of mathematics in the classroom are the basic methods of previewing, listening, reviewing, and homework.

1. How to prepare.

Preview is to read the upcoming mathematics content before class, understand its outline, and know it in your heart, so as to grasp the initiative to listen to the class. Preview is an attempt at independent learning, whether the learning content is correctly understood, whether it can grasp its key points, key points, insight into the implicit thinking methods, etc., can be tested, strengthened or corrected in time in the lecture, which is conducive to improving learning ability and developing the habit of self-study, so it is an important part of mathematics learning.

Mathematics is highly logical and coherent, and new knowledge is often built on top of old knowledge. Therefore, when previewing, it is necessary to find out the knowledge needed to learn new knowledge, and recall or re-review, once it is found that the old knowledge is not well mastered, or even do not understand, it is necessary to take timely measures to make up for it, overcome the learning obstacles caused by not mastering or forgetting, and create conditions for the smooth learning of new content.

The method of preview, in addition to recalling or reviewing the old knowledge (or preparatory knowledge) required to learn new content, should also understand the basic content, that is, know what to say, what problems to solve, what methods to take, the key is to focus on **, and so on. During the preview, the method of reading, thinking, and writing is generally adopted, and the main points, levels, and connections of the content are marked or marked, and their opinions or points and problems are written down, and the main problems or plans to be solved during the lecture are finally determined, so as to improve the efficiency of the lecture. In terms of time arrangement, the preview is generally carried out after review and homework, that is, after completing the homework, read the content to be learned in the next class, and the requirements are flexibly mastered according to the specific situation at that time.

If time permits, you can think more about the questions, delve into more depth, and even do practice questions or exercises. If time does not allow, you can have fewer problems, and there are more problems left for the lecture to solve, and there is no need to force uniformity.

Write about your own real situation.

Learn math with math.

Lingbao City No. 2 Primary School Class Six (6) Chen Yidong.

Mathematics is closely related to our lives, and mathematics is everywhere in our lives. Counting can make your mind pure and add vitality to your mind. It gives you wings of imagination and opens up channels for you to reason.

Mathematics is used in real life to teach us to identify things, to teach us how to make a profit, and to ......

There is such a math problem: the cutting machine produces residues during the soap production process, and the residues from 11 bars of soap can make an additional strip of soap, asking how many additional bars of soap can be made after cutting 250 bars of soap?

Problem Analysis: The average student may directly use the result of 250 11 as the answer, but this is not the case. The first residue should be calculated using 250 11, and from these residues additional soap can be made, so this quotient should be divided by 11, if the result is greater than 11, then divided by 11, if it is less than 11, then add the quotient of the first division, and the result will be calculated.

In this question, 250 11 22 ......7. An additional 22 bars of soap will be added. Now, mixing the remaining 8 bars with the residue from 22 bars of soap, which is equal to the residue of 30 bars of soap, from which another 2 bars of soap can be produced, and the residues after that are not enough to make 1 complete bar of soap, so the residue from 250 bars of soap will make an additional 24 bars of soap. Column:

22+2 24 (block).

A: Able to make an additional 24 bars of soap.

In life, we can often encounter such problems:

One day, Xiao Ming and Xiao Gang went to buy milk on the street together, and when they walked to the door of the dairy store, they saw a sign hanging on the wall, which read, "Our store has launched a 'milk cleaning' promotion, and seven empty milk bottles can be exchanged for one bottle of milk......At this time, Xiao Gang said to Xiao Ming: "This method is really cost-effective!" Xiao Ming said

Yes, it's very cost-effective, you give me the math, if I drink one bottle of milk a day, that is, 365 bottles of milk a year, how to order the most cost-effective milk? Xiao Gang said: "How simple it is, collect 7 empty bottles to exchange for 1 bottle of free milk, with 365 7 = 52 ......."After drinking all 1,365 bottles, you can't participate in the exchange of empty bottles is 1 bottle, and the rest can be exchanged for milk, so you can get it for free (365-1) 7=52 (bottles), so the number of milk bottles you spend money on is 365-52=313 (bottles), so it is most cost-effective to order 313 bottles of milk.

Mathematics is amazing, it will bring us many unexpected surprises and joys, we must learn mathematics well!

1. Pay attention to listening and lectures in class, and review in time after class.

The acceptance of new knowledge and the cultivation of mathematical ability are 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.

2. Do more questions appropriately and develop good problem-solving habits.

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 proven that:

When it comes to critical times, you will be in the same way as you would normally practice. If you are casual, careless, careless, etc., you are often fully exposed in the big exam, so it is very important to develop a good habit of solving problems in ordinary times.

3. Adjust your mentality and treat the exam correctly.

First of all, we should focus on the three aspects of basic knowledge, basic skills, and basic methods, because the vast majority of each exam is also a basic topic, and for those difficult and comprehensive topics as an adjustment, think carefully, try to figure yourself out, and summarize after completing the questions. Adjust your mentality, make yourself calm at all times, think in an orderly manner, and overcome impetuousness. In particular, I must have confidence in myself, always encourage myself, no one can knock me down except myself, I must have my own pride, and no one can break me.

Before the exam, you should be prepared, practice the regular questions, put your own ideas, and do not go to improve the speed of solving the questions on the premise of ensuring the accuracy before the exam. For some easy basic questions, you must have 12 points to get full marks; For some difficult problems, you should also try to get points, and learn to try to score in the exam, so that your level is normal or even extraordinary. It can be seen that in order to learn mathematics well, it is necessary to find a learning method that suits you, understand the characteristics of mathematics, and enter the vast world of mathematics.

1 As shown in the figure, A and B are two new communities on the roadside, and a bus stop should be added on the roadside. To make the distance from the station to the two neighborhoods the same, where should the bus stop be built?

2.An old man who had been through a lifetime of hard work, in his old age, finally had a parallelogram of land, which, due to his old age and infirmity, he decided to divide it among his four children, and he divided it like this:

When the four children saw it, they argued endlessly, and they all thought that they had little land, classmates, do you think it is reasonable for the old man to divide it like this? Why?

Therefore, the land area of the four people is the same, and the old man's land division is reasonable.

3.Xiao Ming's family has a parallelogram vegetable field, there is a well in the middle of the vegetable field, for the convenience of watering, Xiao Ming suggested that his mother build a road through the well, which can divide the vegetable field into two equal parts. Students, do you know how the smart Xiao Ming helped his mother divide it?

4.Coach's worries.

Two shooters, A and B, will now select one shooter to participate in the competition. If you're a coach, which one do you think is the best choice? The test scores of the two shooters A and B are as follows:

The first, the second, the third, the fourth, the fifth.

A hits the ring number 7 8 8 8 9

B hits the ring number 10 6 10 6 8

Please calculate the average score of the two shooters separately;

Based on the results of these two shooters, draw a line chart in the figure below;

Now you have to choose a shooter to participate in the competition, if you are a coach, which one do you think is more appropriate? Why?

The sum of the deviation between A's shooting score and the average score:

The sum of the deviations between B's shooting score and the average score:

Who has good stability? What data should be measured?

The sum of the squares of the deviation of A's shooting score from the average score:

The sum of the squares of the deviation of B's shooting score from the average score:

What else is the magnitude of the sum of squares of the above deviations related to?

It's about the number of shots!

There are also some pictures, if you want them, send me an email.

Math Small**--- Mathematics in life.

The other day, I went to three places, a large shopping mall, a roadside stationery store, and a providence wholesale market. And I found that these three places are much worse on the same product. Therefore, I did a survey about the Super Art GP-8106 Dream Color 6 Color Pen.

In large shopping malls, it is about 5 10 yuan. In a small roadside shop, ** is about 2 3 yuan. In the wholesale market, it is about 1 yuan. It can be seen that on the **, large shopping malls and roadside shops are not as cheap as wholesale markets.

And in terms of quality, I bought a pen in each of the three places, and the quality of large shopping malls, small shops, and wholesale markets is not much worse. However, wholesale markets are crowded and cluttered, and money can be easily stolen, and large shopping malls are too expensive, so buying at a roadside shop can be a good option.

Mathematics is everywhere in life, mathematics is also the foundation of all disciplines, in life, we should use more mathematical methods to think about problems, so that our thinking will be clearer, which is of great benefit to our future.

Don't thank me, I'm in the sixth grade, and I was going to do it, but I just sent it by the way.

If you can solve it yourself, you have to solve it yourself, and mathematics can be found everywhere in life.
