Excellent composition of mathematics 1 Mathematics is a pure subject. You don't have to have a high IQ to learn math well. As long as you lay a good foundation, pay attention to details and mistakes, and learn to summarize the types of mistakes,
So as to draw inferences.
You don't have to talk about sea tactics to do math. As long as you grasp the rules, you can sort out a framework in your mind. Every link in the framework has a typical example. I don't advocate sticking to difficult problems. If I do, I can't do it, which will not only waste time, but also cause frustration. Over time, I will laugh at myself and lose confidence and enthusiasm for mathematics. Doing math problems should be less and more precise, less and more frequent, and learn new things by reviewing the old ones.
I think to learn math well, we must do the following:
(1) Be sure to preview what the teacher will explain before class. For simple things, you should understand and master them yourself, consciously remember axioms, formulas and inferences, and draw things you don't understand;
(2) Listen carefully in class, never lose your mind, pay more attention to your confusion when previewing, and write down typical examples;
(3) Do exercises carefully after class, increase training in places where you are not sure, and recite formulas.
The main way to learn mathematics is to deepen understanding and remember in understanding.
Mathematics is a rigorous subject, and mistakes are not allowed. Through study, I found that to learn mathematics well, we must have a modest and prudent attitude, meticulous thinking and meticulous spirit. The topics are ever-changing and the methods are unique. As long as you master the method of learning mathematics, learning mathematics well is naturally simple.
This year, our math teacher changed, but I still can't forget our former math teacher.
I feel very happy when I think of his gentle smile and what we have experienced together.
Our former math teacher never took up extra-curricular time. Even if he took up other classes, it was our favorite class. And every time we have the last math class before the exam, the teacher will give us a heart-to-heart class, which is our favorite class. I remember a heart-to-heart talk, and the teacher asked us, "Do you have a goal? What is the goal? " Our class almost shouted in unison: "Even if we can't get the first place in the province, we must get the first place in the whole school!" The sound was deafening. This is the goal set by our class under the leadership of the math teacher. The teacher nodded: "Well, then we will all work harder tomorrow." The teacher paused, smiled again and said to us, "In fact, it doesn't matter whether we are the first in the school. The important thing is that we all passed. " After hearing this, everyone was full of gratitude and determined to do well in the exam and not to embarrass the teacher. The class was almost over, and the teacher gave us all some snacks. We went home happily.
I remember that in the end, our class not only got the first place in the whole school, but also got the third place in the whole province! This makes everyone in our class very happy. Maybe it's because we have laid a good foundation with our teacher.
But now, the math teacher who often laughs doesn't take us anymore. Although he is no longer in this campus, I believe we will meet again!
This is our amiable math teacher, who took us through a happy time.
Excellent Mathematics Composition 3 On that day a long time ago, the teacher gave us an interesting math lesson, which was the most interesting lesson I have ever had.
The bell rang and we hurried back to the classroom. The teacher was already standing on the podium, writing something on the blackboard ... I had to take out my book absently. Mathematics has always been a subject I don't like. Very boring, very boring ... I mechanically took notes on my desk, waiting for class to end.
Square, decimal, fraction, percentage ... This course is about the number axis. I thought it was a boring class, but I can clearly feel the cheerful mood of the helicopter students, which is unprecedented in any class. I couldn't help laughing and raised my hand. ...
The teacher compared the numbers to a big family. There are many small families in this family.
Positive numbers, negative numbers ... and more small families, integers and fractions ... The teacher talked about their relationship seriously, like telling the history of a family, occasionally inserting a few humorous words to cause a burst of laughter ... 45 minutes passed in joy, the bell rang slowly, and everyone left the classroom wanting more.
That class. I like math, like those small numbers, abstruse formulas, simple equations ... It was that interesting math class that made me fall in love with math.
Mathematics Excellent Composition 4 Since junior high school, my favorite class is mathematics. Because the teacher's teaching method is unique, which is exactly what we hope, we can learn knowledge happily.
Today, we had another math class. The teacher asked us to understand every question thoroughly, let us stand on the podium as small teachers, and avoid some of us pretending not to understand. Of course, we are all a little scared. If the teacher asks questions, if not, the teacher will get angry and criticize us severely. Then we should listen to the teacher carefully, and the natural efficiency will be high. But there are always some people who doze off as soon as class begins. As soon as the teacher looked at it, he changed his strategy. Let's discuss it in groups first. If the analysis is not in place, the teacher will analyze it carefully. After several analyses, he understood it very well.
Sometimes the content is a little difficult to remember, so the teacher will make these boring contents into jingles and take some actions to let us pass them one by one. Even if we can't remember the jingle, we can remember the relevant content according to the actions we have done. If we have classes like this, we won't be sleepy at all. Of course, our position will constantly change according to our needs. We will press the group position for a while and return to the original state for a while. You think you can still doze off like this?
In fact, our teacher is not only unique in teaching methods, but also versatile. Every class, he will tell us a story, sing a song to make us feel happy, and then enter the lecture process. The teacher also pays great attention to asking questions, so that we can speak boldly and consciously. It doesn't matter whether it is right or wrong. As long as we have this spirit, it is commendable. Whoever answers well is the first to raise his hand to speak, so he will get extra points, the group will get extra points and the individual will get extra points. Of course, if the group gets a high score, the whole group will be honored and do less questions. How beautiful!
Every time I have math class, I am full of energy, because I like this teaching method very much, which is happy and interesting!
If I want to say which teacher I like best, I will definitely answer loudly: "math teacher!" " Because I admire her very much.
I remember when the first grade started, the first class was math. We whispered below: "Is the teacher a man or a woman? What does it look like? How's your temper? ..... "When the bell rang, we sat up straight and looked straight at the gate, only to see a male teacher of medium height, short hair and simple and generous clothes came in. He only introduced himself briefly and then began to give a lecture. He is our math teacher, Miss Ke. Teacher Ke's beautiful words are soft, sincere and sweet, just like the spring breeze with the flowers in the field, which gently blows into our hearts and makes people intoxicated. We think he is a very gentle teacher.
Time flies, four years have passed in a blink of an eye. I gradually found that the math teacher is not so gentle on the surface, but also strict. On one occasion, several students only made a simple' calculation problem' wrong in the final exam. He not only criticized when handing out the report card: "What's the matter? How can such a simple question be wrong? " I have to punish one or two homework.
What I admire most about the math teacher is that he cares about the safety of his classmates. I remember last week, Zhu Weiting threw up, and we were too sick to look. However, the science teacher rushed to the office to get a plastic bag for Zhu Weiting, and then went downstairs to cover Zhu Weiting's vomit in the sand, thus removing the disgusting smell.
This is my favorite teacher, Mr. Ke. Although he is not as famous as those heroes, he is extremely tall in my heart.
I think the most interesting teacher in our school is Miss Tang. She is an excellent math teacher, not only because she teaches well, but also because of her humor, which is deeply loved by students. We all like her.
Teacher Tang has exquisite facial features. At first glance, she looks a bit like Cai Guoqing. She usually wears an orange vest, an orange turtleneck and a pair of dark black sweatpants, plus her shawl curls. She is really a very spiritual person, and her tall and graceful figure looks elegant. He always has a smile on his face, which gives people an amiable feeling.
Teacher Tang has a famous saying: "(You) suddenly understand?" Because she can always teach in an interesting way, she can make us understand the profound truth with simple examples. For example, she used "Simplified Multiplication Table" to guide students to memorize multiplication tables: "Mom and Dad love me" means "Mom and Dad love me". The students burst into laughter and suddenly understood and understood the truth. Every time she tells us a problem, we always feel that our thinking is clear, even complicated math problems can be easily solved.
On another occasion, Mr. Tang saw that I was writing a math problem related to the distribution law of the multiplication table, and I was always suspicious when I recalled the formula, so he said to me, "Think about the analogy the teacher gave you before!" After listening to Mr. Tang's words, I was so sad just now that I suddenly became enlightened and solved the problem at once. I said to myself: Teacher Tang is really amazing! Just say a word and we will "suddenly realize"!
In this way, after knowing Mr. Tang, her humor and infinite wisdom pointed out the direction of learning for me and made me like mathematics more and more.
Our math teacher is both humorous and serious.
Recalling last semester, we had a particularly interesting math class in our class.
As soon as the teacher entered the classroom, he smiled and asked the students, "Have you ever played the math game of grabbing fifteen?" Wang Pengyu and I raised our hands first. The teacher asked us to show you first. I said, "1." He said, "2." ``````` I said, "1 1." "I'm going to lose." I said it again. Unexpectedly, Wang Pengyu said, "12, 13." I said, "14, 15." The teacher announced that I was the final winner.
The teacher said on the platform, "Now the students have all heard the speeches of the two students just now. The method of this game is: everyone can only say two numbers at most, and whoever says 15 first wins. Let the students play the game again between adjacent students. "
Xian Wen and I are thinking while playing games. Is there another game? I started thinking. Slowly, I recall that when I was studying Olympic Mathematics in the third grade, my teacher taught us this game: draw fifteen circles first, then pick up the eraser, and everyone will wipe it down in turn, at most two, to see who can finish it first.
After repeated thinking, I have come to the secret of winning the Tenth Five-Year Plan: you must let others speak first. No matter what numbers others say, you must say these important numbers: 3, 6, 9, 12, 15. When you talk about these numbers, you are the winner of the fifteenth. I think this math class is very interesting, because it not only teaches us a new math game, but also gives me the secret of winning the tenth five-year plan, so I think it is very interesting.
In my impression, the teacher who impressed me deeply was none other than my math teacher.
The young female teacher who teaches mathematics came into the classroom as cold as ice, stepping on thin red shoes and holding a stack of exercise books in her hand. First she glanced at all the students with cold eyes, as if to say, "I will never forgive anyone who speaks again!" " "Suddenly, the noisy classroom suddenly quieted down. Immediately, the teacher threw the exercise book on the platform, and the students trembled with the noise. The teacher patted the table rhythmically with delicate hands and said in a sharp and blunt voice, "I am very dissatisfied with this assignment!" " "This sentence made the temperature in the classroom drop to four thousand degrees below zero, and several students trembled involuntarily. As we all know, the nightmare is about to begin. I saw the teacher pick out an assignment at random, turn over a few pages, read it for a while, and then bang, with a voice that can cut the eardrum, he shouted, "Wang Zihao! Look at your homework, what have you written! " Look at Wang Zihao, which has fallen to the ground in the earthquake.
The second characteristic is easy to get angry. Once in class, the teacher assigned us many questions and asked us to finish them in 10 minutes. How can we do it so fast? How time flies! 10 minutes arrived at once, but I only did half of it. As soon as the teacher checked and saw our listlessness, he suddenly flew into a rage and said, "You are really useless. You can't even finish this. What kind of student are you? " Do these questions for me 10 times. "It's all over. The teacher's anger brought us great misfortune.
This is my math teacher. Although he may be bad in your eyes, in my heart, I still think he is a serious and responsible teacher.
There is a strict teacher in our class. He is tall and a little fat, but he is beautiful. Don't just look at the teacher as beautiful as flowers and jade I want to tell you that this beautiful teacher is very strict. She is our math teacher.
Once in class, I couldn't help but doze off in class because I didn't sleep well the night before. The teacher's jewel-like eyes looked at me immediately, full of severity, which scared me and refreshed me. Another time, the teacher asked us to copy our homework, and one of our classmates was whispering. As a result, the whole class was fined five times. Some students were unconvinced and said that the teacher was too outrageous. Why punish the whole class for talking alone? This is so unreasonable! "Because you are a group." In the face of classmates' complaints, the teacher said unhurriedly, but in a firm tone.
One thing I remember most clearly is the exam. Our class came last in the third grade exam, and the headmaster criticized the teacher. To our surprise, instead of criticizing us, the teacher looked at us calmly and encouraged everyone: "As long as we work hard, we will succeed."
From then on, all the students in the class admired the teacher and stopped speaking ill of him. I also secretly made up my mind in my heart: I will be strict with myself and make myself better to repay the teacher's love.
Excellent Mathematics Composition 10 "Bell, Bell, Bell ……" The bell rang, and the students came into the classroom one after another, waiting for the arrival of the teacher.
At this time, Mr. Jing came to the classroom with a book in his hand. Unlike usual, the teacher came straight to the point and said, "Let's play games today." "Hey, isn't it a math class?" I whispered to myself. At this time, Mr. Jing poured a bag of yellow colored balls into the box for a classmate to touch. Then let's raise our hands and guess what color it is. I stood up confidently and answered, "Yellow." "Why?" "Because everything you pour in is yellow." The teacher smiled and said, "You have observed it very carefully." Next, Mr. Jing poured the blue, orange and white balls into the box and said, "If you touch another one now, what color will it be?" Everyone rushed to answer, some said blue, some said orange and some said white. I'm stunned now. What color will it be? Finally, Teacher Jing gave the answer: it may be blue, orange or white. Through this little game, Mr. Jing made us realize the possibility in mathematics and made us interested in mathematics.
"Bell, bell, bell ..." This math class ended in a relaxed and pleasant game.
1 1 My math teacher is short and thin, like a monkey, not bad at all, like a chameleon, and he hits people badly. Why do I say that?
Once, the math teacher said to our classmates, "You have little homework to write on Sunday." At this time, I am very happy, because the homework has piled up in recent weeks. However, after school in the afternoon, I saw my math homework as high as Mount Tai, and I thought to myself, the math teacher is really like the chameleon I said.
After Sunday, another week began. The math teacher came and said to the students, "Who didn't finish the math homework today?" I saw rows of people suddenly standing up, blocking my view. Suddenly, I heard crying. At that moment, tragedy happened. I leaned down and saw the teacher slapping my classmate's palm. That classmate cried loudly, so the teacher pulled him away and dealt with another classmate. Finally, the class was over, the teacher left and the students went downstairs to play. I called the classmate who was beaten by the math teacher to my side and asked the teacher how to beat him. He said: "The teacher first pulled me to the math teacher, and then pulled my poor little hand out and beat it hard. The pain is beyond description. I thought to myself, the teacher is really a chameleon and a tigress!
Recently, I accompanied my mother to the market and saw many chickens in cages. My mother told me a classic math story-the problem that chickens and rabbits are in the same cage. When my mother and I came home, we learned this interesting math story together.
Chickens and rabbits are in the same cage, which is one of the famous interesting topics in ancient China. About 1500 years ago, this interesting question was recorded in Sun Tzu's calculation. The book says: "There are pheasant rabbits in the same cage, with 35 heads on the top and 94 feet on the bottom. Pheasant rabbit geometry? " These four sentences mean that there are several chickens and rabbits in the same cage, counting from the top, there are 35; It's 94 feet from the bottom. How many chickens and rabbits are there in each cage?
The solution to this problem: assuming that all chickens are chickens, then we can calculate how many feet there are under the assumption according to the total number of chickens and rabbits. Compare the number of feet obtained by this method with the number given in the question to see how much difference there is. A difference of every two feet means 1 rabbit. Divide the difference by two to calculate how many rabbits there are. To sum up, the basic formula to solve the problem of chickens and rabbits in the same cage is: number of rabbits = (actual number of feet-number of feet per chicken × total number of chickens and rabbits) ÷ (number of feet per rabbit-number of feet per chicken). Similarly, it can be assumed that all rabbits.
The problem of keeping chickens and rabbits in the same cage can solve many mathematical problems in life, especially the idea of "hypothesis method", which is very novel. Although I am not familiar with the gist and mystery, after this question, I understand the close relationship between mathematics and life, which aroused my enthusiasm for mathematics learning.
Excellent Mathematics Composition 13 Today's homework is "Do you often do housework?" What about other students? " First use the following questionnaire to investigate, then sort out the survey data and complete the statistical table. The questionnaire is like this:
Do you often do housework? Choose the appropriate scenario to fill in.
Do it every day () often () seldom () never ()
I usually stay at home. As long as my parents finish my homework, I can pack my schoolbag at most. I seldom do housework at home, and it's rare to wash dishes 1 time, but that's the homework assigned by the teacher, but I'm embarrassed to write it and never do it. How embarrassing, so I chose "seldom do".
After arriving at school the next day, I found through communication that there are 5 people every day; There are 12 people who often do it, 29 people who rarely do it and 2 people who never do it. I guess there may be some students who are as disgraceful as me, and the data here is not accurate. The fact is that there are fewer people doing housework than the statistics.
At noon, when I was reading Mathematics Bulletin for Primary and Secondary School Students, I saw a statistic about the working hours of primary and secondary school students in various countries: 72 minutes in the United States, 42 minutes in South Korea, 36 minutes in France, 30 minutes in Britain, and only 12 minutes in China.
I feel so embarrassed. I can't even reach the average. Many of our classmates should be in the same situation.
Excellent mathematics composition 14 should attach importance to learning and understanding mathematics from students' life experience and existing knowledge. Because life is inseparable from mathematics, and mathematics is inseparable from life. Especially in primary school mathematics, we can get the rudiment of mathematics in our life. When we students eat porridge, we have a lot of familiar math knowledge around us. For example, when we go shopping, we have to add and subtract, and when we decorate a new house, we always have to draw pictures ... There are countless problems like this, which arise from our lives, and those are all "living" textbooks of mathematics!
In the past, students learned mathematics knowledge mechanically, and transferred that knowledge directly from books to their brains, which was rarely applied flexibly to real life. But it's very different now. Students have learned to apply mathematics to their lives. For example, I once went to my classmate's house to play, and my classmate was alone at home. Early in the morning, we were all hungry, so my classmate ran into the kitchen and began to cook breakfast by himself. At first, the classmates washed rice and put it in the pot, and then began to cook porridge. Then bake three cakes while cooking porridge. He first put the first and second cakes in the pot. A minute later, he took out the second cake, put it in the third cake, and turned the first cake over. Bake for another minute, so that the first cake is ready. He took it out, put the reverse side of the second cake in the pot, and turned the third cake upside down, so that it only took three minutes for the three cakes to be baked, and he could cook other dishes in the remaining time of porridge cooking. If he is cooking and doing nothing else, isn't it a waste of time? Then he won't lose much! Therefore, life cannot be separated from mathematics, and mathematics cannot be separated from life.
Students, let's explore the mystery of mathematics and discover mathematics in life!
If you ask me which teacher I like best, I will definitely say math teacher.
My math teacher's name is Wang Liping. She teaches very carefully. Once in a math exam, I accidentally forgot the point above 3 of the circulating decimal 0.3. I thought the teacher might not be able to see it after handing in the test paper. As a result, the paper was handed out and found by careful teacher Wang. If I am good, I can get 100, so I deducted 0.5 points, which is only 99.5 points. I hate myself at heart. Teacher Wang called me to the podium and severely criticized me. But I know in my heart that Mr. Wang's criticism is for my own good and for my love, so that I can get good grades in the next exam.
Miss Wang is not a class teacher, but she cares about me like a class teacher. I remember another time, I took part in the 800-meter competition of the school sports meeting, and I couldn't run any more after running for two thirds. I want to give up, but I can't get the ranking anyway. At this time, Teacher Wang encouraged me not to be discouraged. Persistence is victory, and he kept shouting "Come on" to me. I finished the 800m race and won the third place. I was very happy and said to myself, "Thank you, Miss Wang. If it were not for your encouragement, I wouldn't have won the third place. " .
Miss Wang is now 40 years old and her hair is gray, but she still teaches seriously. I remember once I didn't understand a topic. Teacher Wang said it three times in a row before I understood.
This is my math teacher, Miss Wang. She often sacrifices her rest time to make up lessons for me. She has to work overtime at night and have class the next day. How hard it is. I love Miss Wang.
