1. How to learn math and write a Chinese composition? Although it is a stupid method, it can't be said to be an effective method.

I don't think I am a smart person. I have my own methods of learning mathematics for reference only: mathematics; Understanding is the most important point, that is, you must first make sure that you can understand. If your biggest difficulty is that you don't understand in class, you might as well calm down and see which aspect of your knowledge is vague first. Often those vague points are the weak points of your previous knowledge. Knowing these vague points in the past is of great help to your understanding now. When you understand the knowledge points, it doesn't mean that you have mastered the knowledge. At this time, you need to consolidate by doing related topics. At the same time, you consolidate not only the knowledge you have learned at present, but also the answers to each question have a great relationship with the previous knowledge points. Remember, you should not only do the problem correctly, but also look at its problem-solving methods and ideas. From those problem-solving methods, you can get a lot of problem-solving skills and learn to follow suit. One more thing, it is to do the problem, not to look at it. You can do what you want, but you must not be lazy, so your eyes are superior and your eyes are inferior!

In order to improve Chinese composition, certain extracurricular reading materials are necessary. Story-based reading materials can provide you with a lot of writing topics, make you have something to say, be of great help to argumentative writing, and be good at giving examples. Some beautiful prose needs to be carefully written down, especially the beautiful sentences in the text, and you should learn to turn other people's works into your own characteristics. News also needs attention, because in composition, examples with strong timeliness are often refreshing. Of course, don't forget that it is also important to choose a good composition. Through other people's compositions, you can see how an excellent composition is conceived and see their ideas clearly, so that you can be organized in your writing. Write boldly and frequently.

2. How to write my findings in math composition

Students, have you made some casual discoveries in math study like me? Now I will introduce some of my findings.

If you want to calculate a multi-digit multiplied by 5, do you want to calculate it vertically? But I can do it with my mouth, because I found a little trick. Do you want to know? Let me tell you: calculate the product of 48532*5, first find this number 485320, and then divide it by 2. Can I take it orally? 242660 This is the product of 48532*5. Do you know why? I first expanded the original number by 10 times, and then reduced it by 2 times. Is it equivalent to expanding five times? Have you mastered this little trick?

I also found the same thing: multiplying a number by 1.5 only needs to add half to itself. (think about why? How about a number multiplied by 15? Use the method just now to add one more step-you have already thought of it, and then expand it by 10 times!

I also found a multi-digit, and the last two digits meet this requirement: ten digits are odd and one digit is 5. Multiplied by 5, the last two digits of the product must be 75. I think why is this? Because the unit of multiple digits is multiplied by 5 to get 25, the unit of product is 5, which is the tenth power of 2, and the odd number of ten is multiplied by 5 to get 15. This 5 must be added with the 5 to be written on the ten, so the product must be the tenth power of 7 and the tenth power of 5. In the same way, it is not difficult for you to deduce that a multi-digit number is even in ten digits and 5 in one digit. It is multiplied by 5, and the last two digits of the product must be 25.

Can this discovery be explained by an ingenious algorithm of multiplying numbers by 5 that I mentioned earlier? Think about it, they are the same, because after this number is expanded by 10 times, the last two digits are 50, and then divided by 2, there may be a remainder of 1 in the hundreds, and when combined with 50, 150÷2=75 is the last two digits, or there may be no/kloc-0 in the hundreds.

Students, is my little discovery insignificant? But I am very proud, this is the result of my own observation and thinking. Aren't great discoveries made up of these bits and pieces? Students, let's be a diligent thinker and discoverer!

3. How to write a math composition and learn from many experiences? Writing should have a main line and a clue that can run through the whole text.

As far as my own feeling is concerned, I should read more books. Maybe after reading the book, you will feel that you can't keep anything and forget it in an instant. But books will have a spiritual impact on you. If you read more books, you will naturally be influenced by them, and you will naturally absorb the strengths of a hundred schools of thought, thus forming your own style.

Sometimes books can make you bored. Don't read the explanation book, read what you like and integrate yourself into the book. You'll feel like the main character. Write something simple, such as affection. Don't be vulgar There is no need to paint a thing as normal. You can use parallelism to list some small things into paragraphs and strengthen the tone. Finally, just write a little pen.

You're welcome.

4. How to write the understanding of 0 in mathematical composition

0 is a wonderful number and an "old friend" that middle school students often meet.

First of all, 0 means nothing, which can be called "desert" in numbers. 0 is also a strange number. In all units such as volume, area, weight, speed and distance, it doesn't mean time, a person's age, the starting point and the starting point of a game.

Among the natural numbers in the digital library of the mathematical kingdom, one number is 0, which is of course the smallest. Without 0, there is no natural number, because 0 is the starting point of natural number.

exist

In calculation, when 0 is multiplied by any number, including negative numbers, fractions and 0, the absolute value of 0 is also equal to 0. Among rational numbers, its absolute value is the smallest. If 0 is divided by any number, 0 plus a number will still get that number.

Number, such as: 0+ 1 = 1, 0+1.8375 =1.8375.0 Subtract a number to get the reciprocal of the number, such as: 0- 1 =- 1.

In the number axis, 0 is

The origin, which is also the boundary line, separates positive numbers from negative numbers. Why is 0 wonderful? Because 0 is neither positive nor negative, it is just an integer. When 0 is together with a positive number, it is called non-negative. When it is negative,

It is called a non-positive number. On the number axis, 0 provides great convenience for us to judge the size of positive and negative numbers. The right is positive, the left is negative, and the number on the right is always greater than the left, which means that the positive number is greater than the negative number, and 0 is greater than the negative number, but less than.

Positive number.

In geometry, an angle of 0 degrees means a ray, which has no angle or degree. 0 square meters means no area, 0 meters long means no height, 0 kilograms heavy means no mass, and 0 cubic meters means no volume.

In topography, 0 means sea level, above 0 means above sea level, below 0 means below sea level. Xinjiang in China has a basin with an altitude of155m, and Tibet in China has Mount Everest with an altitude of 8848m.

At noon today, in order to measure the size of chopsticks more accurately, I asked my father to bring a slender measuring cylinder from the chemistry room. The scale unit is smaller, and each unit is only 1 cubic centimeter. At this moment, I seem to feel victory beckoning to me. I really have everything except hands-on experiments.

first

First of all, I drew a dividing line on disposable chopsticks with a pencil, divided the chopsticks into two sections evenly and soaked them in water to prevent them from being washed by water during measurement. Then, I insert chopsticks into the measuring cylinder and drop water into the measuring cylinder with a dropper.

3. Let the water in the measuring cylinder rise to the dividing line of chopsticks, record the water level scale (38 ml) in the measuring cylinder, then take the chopsticks out of the measuring cylinder, and record the water level scale (34.5 ml) in the measuring cylinder twice.

The difference between scales is the volume of this part of chopsticks, which is 3.5 cubic centimeters. Similarly, I measured the volume of the other part of the chopsticks as 5 cubic centimeters, and the volume of the chopsticks obtained by adding the two measurements is as follows.

8.5 cubic centimeters. When I got the result, I cried excitedly. How proud and proud I am at this time!

Then, I calculated our school with 3 pairs per person a day.

(1.500 people) and the whole country (1.200 million people) consume disposable chopsticks 13.96 cubic meters and1/69000 cubic meters respectively. As a result, I am surprised that so much wood is made every year.

What a pity that disposable chopsticks were wasted! I hereby appeal to the students at school, no! It is the people of the whole country, and it is not! Everyone in the world should stop using disposable chopsticks. Only in this way can we protect them.

Our forest resources make our earth's environment better, so that everyone on earth can breathe clean and fresh air.

Baidu knows how to type "math composition" ... I'm not sure which one you want.

I'm glad to help you. Please adopt it.

5. How to learn mathematics well and write a good composition Mathematics is a multifunctional subject with strong logic and systematicness.

There should be more scientific learning methods to learn and master mathematics knowledge. If the method is right, you can "hard work pays off" and get twice the result with half the effort; If the method is wrong, it will be "thankless" and get twice the result with half the effort.

If learning is effective, the more you learn, the greater your interest; If your academic performance is always low, you will gradually lose your confidence in learning. Whether to master more scientific learning methods is the key to learning success or failure.

Especially in the new learning stage, with the increase of learning subjects and the acceleration of learning rhythm, it is necessary to adjust learning methods in time to meet the learning requirements of the new stage. Otherwise, you will fall behind and fall behind.

We should learn to manage our own learning and master more scientific learning methods. Combined with many years of teaching experience, we believe that a more scientific learning method is mainly embodied in the following five basic links.

First, prepare well before class and master the initiative in class. Classroom is a battlefield, learning is a war, and you can't fight an unprepared battle.

If you have a math class the next day, you should be fully prepared on the first day. On the one hand, we should read through the relevant contents in the textbook to see what we know and what we have learned; What you don't understand is new knowledge that can only be understood through the teacher's explanation.

Mark the parts you don't understand, do preliminary thinking and put forward the problems that need to be solved. On the other hand, you should do the exercises at the back of the textbook for the first time, and the questions you can't do should be marked and brought to class to solve.

Doing so will enhance the purpose of attending classes, master the initiative of attending classes and improve the effect of attending classes. Long-term adherence to preview can also cultivate the habit of reading and form the ability of self-study.

2. Listen attentively in class, take notes and get into the state ahead of time. The quality of preparation before class directly affects the effect of listening to lectures.

Before the formal class and the teacher comes into the classroom, you should put the relevant textbooks (including notebooks and exercise books) and stationery on the desktop in advance and wait for the teacher to arrive. Don't expect the teacher to stand on the podium and wait for everyone to slowly rummage through the closet, looking for this and that.

When teachers enter the classroom, they should take the problems that need to be solved in the preview process and concentrate on listening. We should also master the rules of teachers' lectures, pay attention to the particles of teachers' lectures, think positively and answer teachers' questions enthusiastically.

Especially in class exercises and homework, we should strive to answer quickly and accurately. We should also grasp the main points of the teacher's lecture, take class notes and write down the main points, key points, difficulties, keys and typical examples of the teacher's lecture.

There are still some questions that you don't understand, so that you can continue your study after class or ask a teacher for guidance. 3. Review in time and turn knowledge into skill review is an important link in the learning process.

When reviewing, you should read the textbook again, recall what you learned that day, recall the process of the teacher's lecture, reproduce what you learned in class, read the examples that the teacher said (these examples usually have a strong inspiration and demonstration effect on completing the homework), and understand and remember the basic definitions, theorems, formulas and rules (these are all knowledge points that must be mastered). Reviewing in time on the same day can reduce knowledge forgetting and make it easy to consolidate and remember.

Regular review can systematize knowledge, deepen the understanding of knowledge and master the relationship between knowledge. At the same time, only systematic knowledge is beneficial to application, the transition from knowledge to skills and the mastery of updated knowledge.

Review should be planned, not only to review the lessons of the day in time, but also to review all stages in time. 4. Seriously finish homework, form skills and skills, and improve the ability to analyze and solve problems. Academician Yang Le said three short sentences when answering the question of how middle school students learn mathematics well: First, practice more on the basis of understanding, second, accumulate more on the basis of understanding, and third, step by step.

The exercise here is to do the problem and finish the homework. Homework is the main means to practice using knowledge.

Be sure to review your homework first. In addition to requiring independent completion of homework and opposing plagiarism, homework must also be written neatly and in a standardized format.

Read and copy the questions carefully. If you copy the questions carefully, you can hone your will and examine the meaning of the questions.

In the learning stage of the new lesson, copying questions is not an unnecessary burden, and you can't be lazy to copy questions on the pretext of taking up time. You should examine the questions before you answer them, and the answers should be correct.

Check homework, reduce unnecessary mistakes and lose points, ensure the quality of homework, and form a good habit of being serious and responsible. Through homework practice, we can deepen our understanding of knowledge, consolidate what we have learned, form skills and skills, and cultivate our ability to analyze and solve problems.

Homework should be handed in on time, and on the basis of independent completion on time, it should be correct, neat and rapid. All the mistakes pointed out by the teacher when correcting must be understood in time and corrected seriously.

At the same time, multiple solutions to one problem are allowed, independent thinking is advocated, and creativity is encouraged. 5. Make a summary in time. After studying a topic or a chapter in an orderly and systematic way, we should summarize it in time.

Summing up is to sort out the relevant knowledge of each topic and chapter, compare similarities and differences, find mutual connections, and extract substantive things, such as definitions, theorems, formulas, laws and so on. Summarize with concise words or make it organized and systematic with charts.

The second sentence of Academician Yang Le's Introduction to Learning Methods requires "accumulating more on the basis of understanding". This materialized and systematic process is actually a process of accumulation, which can not only deepen the understanding of knowledge, but also promote the accumulation and memory of knowledge.

There should be a summary at the end of each topic and a systematic summary at the end of each stage. When summing up, in addition to summing up what you have learned, you can also write down the associations, conjectures and discoveries inspired by relevant knowledge for further thinking and research.

You can also sum up your own experience, experience, experience and lessons in learning methods. Especially after the half-term and semester exams, it is more necessary to summarize the learning methods in combination with the results of various subjects, and make the next stage of learning plan on this basis.

At this time, experienced teachers will also organize students to communicate with each other, learn from each other's strengths, constantly adjust and improve, constantly improve their learning methods, and gradually learn to manage their own learning scientifically, so as to learn easily and effectively and constantly improve their academic performance. The above five links are interrelated and influence each other.

How to realize each link.

6. Mathematical reading experience: the story of a mathematician, written in 500 words. Today, I read the story of mathematician Xu Lizhi, and learned that Mr. Lao Xu has made contributions to the motherland in mathematics. Many of his papers have aroused international repercussions, and he has also trained a group of successful students. Why did Mr Lao Xu become a mathematician? Why can you make such a great contribution? One of the reasons is that he was not afraid of difficulties and studied hard when he was a child. The article wrote: "When he was studying, he often saved his uncle's lunch money to buy books and exercise books. In order to save paper, he often practices writing on the sleeping mat with his fingers. In the dead of night, his classmates have entered a sweet dream, but Xu Lizhi came to the corridor and studied hard under the light. During the day, he soaked in the library and used steamed bread and boiled water to satisfy his hunger ... When xu teacher was a child, his study conditions were so poor that he didn't even have the money to buy books and exercise books, so he had to scrimp and save for lunch. But he studied hard and was not discouraged by poor learning conditions. In our time, family life is relatively rich, and many families have only one child, so we have more pocket money. We either play video games or buy delicious food. Usually, this is also a waste. A piece of paper was thrown away without writing a few words. I don't know anything about saving. In learning, many students are not studying hard now, and their learning purpose is not clear. Me, too. I get discouraged when I encounter a little difficulty in doing the problem. Compared with Mr. Lao Xu's study spirit of forgetting to eat and sleep, there is really a gap of 108,000 miles. From now on, I will use Mr. Lao Xu's learning spirit to motivate myself and study hard. In the future, I will contribute to socialist modernization. Gauss once heard a story: Gauss is a second-grade primary school student. One day, his math teacher wanted to finish it, because he had dealt with more than half of the things, even though he had a class, so he planned to give the students a math problem to practice. His topic is: 1+2+3+4+5+6+7+8+9. Because addition has just been taught for a long time, the teacher thinks it will take a long time for students to work it out, so that they can use this time to deal with unfinished things. But in the blink of an eye, Gauss had stopped writing and sat there doing nothing. The teacher was very angry and scolded Gauss, but Gauss said he had worked out the answer, which was 55. The teacher was shocked and asked how Gauss worked it out. I just found that the sum of 1 and 10 is the sum of1,2 and 9, 1 1, 3 and 8, 1 1, 4 and 7. And11+1+1+1+11= 55, that's how I calculated it. Gauss grew up to be. It is worth learning and emulating. In the winter vacation, I read a book called The Mathematician's Story, which tells the stories of many famous mathematicians, such as Pythagoras, Archimedes and Gauss ... Among them, I am most interested in the story about Zu Chongzhi. Zu Chongzhi was a great scientist in the Southern and Northern Dynasties, and he got very accurate results in the calculation of pi. This article is about the long history of Zu Chongzhi. Finally, Da Liming wrote to the emperor, demanding its promulgation and implementation. The emperor ordered Dai Faxing, a favorite in charge of astronomical calendar, to review it. But Dai Faxing is a conservative and a defender of decadent forces. He strongly opposes the new calendar. In the face of Dai Faxing's difficulties and attacks, Zu Chongzhi was unmoved and argued with him endlessly. Finally, Da Liming failed and later died in Zu Chongzhi, 65438. " Da Liming "was promulgated and put into practice. After reading this story, I admire Zu Chongzhi's indomitable spirit. It is because of this spirit that he can persist. Yes, anything can be successful without the word "persistence". I can't help thinking of many people, including cultural celebrities, patriotic soldiers and classmates around me. Remember, my mother told me. I insist on doing things well so that I can sleep peacefully. Reading The Mathematician's Tale makes me like mathematics more, and it also makes me understand that after reading the stories of three female mathematicians, I deeply sympathize with their unfortunate experiences, but at the same time I am deeply moved by their fighting spirit. Among them, Hipatia impressed me the most. She was born in Egypt around 370 BC. She began to follow her father at the age of six. Her learning attitude is very practical. She always ignores all kinds of charming temptations outside the window and concentrates on reading the book in front of her. The noise in the street drifted into her study from time to time, but she sat at her desk like a deaf person, indifferent to all this ... at that time, she was only 6 years old! I can't help thinking of myself shamefully. When I was in the self-study class, there was a slight trouble on campus, so I couldn't sit still and looked out of the window quickly. How can I learn my lessons well? When I read the topic of "tragic death", my heart was shocked and I didn't know what misfortune had happened to Hipatia. I can't wait to read on: "A group of thugs tore off her clothes under the orders of Syl, and the sharp insect shells stripped her skin, cut off her hands and feet and threw them into the fire ..." When I read this, my eyes were full of tears. I hate those vicious thugs, and I hate the reactionary underworld even more. A famous scholar was dismembered so inhumanely that he couldn't have done it without an advanced social system. The mathematician's story-Su 1902 was born in a mountain village in Pingyang County, Zhejiang Province. Although his family is poor, his parents are frugal and he has a hard time going to school. In junior high school, he was not interested in mathematics and thought it was too simple to learn. Later, a math class influenced his life. That was when Su was in the third grade. He was studying in No.60 Middle School in Zhejiang Province. A teacher Yang, who has just returned from studying in Tokyo, teaches math. In the first class, Mr. Yang doesn't talk about math and tells stories. He said, "In today's world, the law of the jungle, the world powers rely on ships to build their guns and gain profits, and all want to eat and carve up China. The danger of national extinction in China is imminent, and the revitalization of science and the development of industry are imminent.

7. How to write the math composition around me? Different math friends. Mathematics is everywhere in life. If you are not careful, it will get you into trouble.

Once, my mother bought me 10 yuan egg noodles. She said the rest of the money was at my disposal. I patted my chest and said, "It's a piece of cake. I promise to complete the task. "

I said, taking the money and walking out the door. When I arrived at the supermarket, I first spent 50 cents of 4 yuan on egg noodles, and then I began to wonder what school supplies I could buy with the remaining 50 cents of 5 yuan.

I bent down and carefully observed the price tag of stationery. A bottle of carbon ink is 4 yuan, an exercise book is 50 cents, and the remaining 1 yuan can just buy two beautiful greeting cards.

I don't trust it. I calculated it carefully and it happened to be 10 yuan. I thought to myself: when I get home, my mother will praise me for being really capable and accurate in accounting, so I can be a small accountant.

Thinking of this, I jumped to the cashier with the goods. The cashier "bangbangbangbang" calculated an account and said, "A *** 19 yuan."

I was surprised and said, "I don't have so much money with me." Can I not buy it? "The cashier said firmly," no, it has been accounted for. "

If you have no money, ask your parents to pay. "I was so anxious that I almost cried. The more I thought about it, the more wrong it was: how did it become 19 yuan when it was clearly fine? I had a brainwave and got up the courage to say to the cashier, "Are you mistaken? ".

I've seen the price tag, such as 50 cents for each greeting card. Before I finished, the cashier patted his head and said shyly, "Little friend, I took 50 points as 5 yuan, one decimal point short, which caused you trouble. Well, you have to pay 10 yuan. "

I readily paid 10 yuan, took the goods and went home happily. You see, the little things in life are also inextricably linked with mathematics, which enriches our lives.

If you don't know math, it will play tricks on you; If you are proficient in mathematics, it will listen to you and become your good friend. Math, too naughty.
