Sixth grade mathematics composition

No matter in study, work or life, everyone will be exposed to composition to some extent. Composition is a transition from an internal language to an external language, that is, from a compressed, concise language that one can understand to an external language form with a standardized grammatical structure that others can understand. So have you ever studied composition? The following is the 10 sixth grade math composition I collected for you. Welcome to read the collection.

The sixth grade math composition 1 describes Gauss's outstanding performance in the field of mathematics, and introduces some interesting short stories about the life of the greatest mathematician in the world, which makes people admire and yearn for it.

Gauss showed great talent very early, and at the age of three, he could point out the mistakes in his father's book. Gauss entered primary school at the age of 7 and took classes in a dilapidated classroom. When Gauss was ten years old, the teacher took the famous test from one to one hundred, and finally discovered Gauss's talent. Knowing that his ability is not enough to teach Gauss, the teacher bought a deep math book from Hamburg for Gauss to read.

Gauss once said, "Mathematics is the queen of science." People who have made great achievements in mathematics are called "mathematical princes". /kloc-before the age of 0/9, he solved a mathematical unsolved problem of more than 2000 years in one night-the drawing of regular heptagon ruler and ruler. At the age of 22, he received his doctorate and became a scholar invited by various countries.

Even the greatest mathematician in the world has to spend a whole night drawing on paper while thinking, trying to find the answer with some unconventional ideas, in order to solve a mathematical unsolved case of more than two thousand years.

In addition to mathematics, Gauss has been engaged in astronomical research, geodesy and physical research, and has made very high achievements in various fields. Although Gauss doesn't like flashy glory, after he became famous, the glory from all walks of life rained on him and affirmed his contribution. Gauss has always maintained a diligent attitude throughout his life, which makes it hard to imagine that he is a great professor and the greatest mathematician in the world.

Math composition of grade six and grade two has always failed in math quizzes recently, and has been scolded by my parents several times. My parents can't understand. Why did I spend a lot of time teaching again and again, but I still failed the exam?

In fact, I have a long-hidden secret in my heart, that is, I am very afraid of mathematics, and I always have an inexplicable fear of mathematics! Since I entered the first grade of primary school, I have found math difficult. My parents want me to be responsible for my study in order to raise their demands on myself, so they often set performance standards for me and strictly require me to reach the set performance goals. Every time I think about what my parents want of me, I get more nervous. The terrible thing is that when I am nervous, I often make mistakes in the topics I wrote before. In this way, my grades will naturally be ugly, and I will be more nervous and afraid. As a result of such a vicious circle, my parents will be more worried and I will be more afraid of math.

After the teacher shared it with my mother, my parents said to me, "We won't punish you if your grades are not satisfactory in the future, as long as you study hard and work hard." After listening, I was relieved, as if a big stone had been unloaded from my heart. I remembered what the teacher said: "Don't be greedy every day, take your time, it is enough to sort out one idea at a time!" " Let my confidence increase a lot, I am determined to overcome my psychological obstacles, face math bravely, and strive to be good friends with math. I believe my math ability will get better and better, and I can become more confident!

Last time, we visited our old friend "percentage", and this time we will continue to discuss the percentage of "old friends".

Last time, only the "first wisdom gate" of percentage application (1) was discussed, that is, the application of finding the phase difference first and then dividing it by the unit "1"; Then, let's visit the "second door of wisdom". Do you have the courage to accompany me to explore? If so, come on!

As soon as I entered, I saw a problem that must be understood. For example, the price of an induction cooker in Sunshine Supermarket is 320 yuan, which is cheaper than the original price in 80 yuan. How much has the price of induction cooker been reduced? Let's explore slowly. Teacher Zhang told us: "This line is a kind of flashback in percentage application. When encountering these problems, we must first complete key sentences. " For example, we add "the price of 20 yuan" before "80 yuan is cheaper than the original price", so that we can explore it better. We can first calculate the unit "1". Original price 320+80=400 yuan. We know the difference (80). Then we divide the first 80 by 400, which equals 20%. We got the key to the second small door. We continue to open the second door, only to see a formula "find the unit first". We explored the percentage of "the second door of wisdom" and I learned a lot. Now let's compare.

The first one we don't know the difference, and the second one we know the difference; The first is that we know the unit "1", and the second is that we don't know the unit "1". The first one is easy for us to do. We just need to find the difference before and divide it by the unit "1". The second one is more difficult, but we just need to complete the sentence, then find the unit "1" and divide it by the unit "1".

Today, we have explored the "second wisdom gate" of percentage, and we will meet another "wisdom gate" soon.

Once upon a time, I hated and rejected mathematics. Once upon a time, how much I liked and was obsessed with mathematics. This change began when I met this math teacher in the fifth grade. It is she who has improved my logical thinking ability and inspired my interest in mathematics, as well as a competitive mentality.

The teacher's surname is Li, and his single name is "Na". Sometimes I have a bad temper, and sometimes I have a mild temper. Pull a face like "Changbai Mountain" in class, and be as kind as our good friends after class. Everyone in our class calls her "double-sided" in private. I remember once in a math class, after repeated explanations, Mr. Li saw that we were still at a loss, and threw the chalk in our hands angrily, pitying the chalk for breaking bones instantly, which showed Mr. Li's strength. She flew into a rage and said, "You won't, didn't you listen carefully?" Stop learning! Class two and class three talked about one class, and we all talked about three classes! What's the matter with you? You all know the truth, why don't you know how to do it? Hum! I still want to get into a good school. At this rate, I can't get into primary school ... "At this time, Miss Li is like an angry child. She stared at us for several seconds, but the deterrent was still great. When the whole class held their breath and was silent, Fang drew another piece of chalk from the chalk box and continued to teach us.

Although Miss Li is very popular in class, it is different after class. When I handed her the corrected homework, her face smiled into a flower: "Well, by the way, will it be this time?" I quickly replied, "Yes." Teacher Li smiled even more brightly: "Well, you are great, go out and play!" " "I immediately" flew "out, relieved and elated.

There were no clouds in Wan Li that day, but I was asking questions in Miss Li's office. Miss Li patiently explained to me: "Who is the 1 unit here? Is the total number of apples ... isn't it? The question is who? ..... pears, then why not apples? Because there is no total amount of apples! ..... "But my brain just couldn't turn around and always thought that my method of solving the problem was correct. In the huge office, teachers and students are arguing like no one's watching, and the air is filled with strong gunpowder. Until the bell rang, I still "couldn't save my doubts." So Mr. Li said, "I'll tell you this afternoon. Think about it when you go back, and then I'll tell you something about the characteristics of this kind of questions, practice some basic questions, lay a good foundation, and make in-depth research ... "

Under the strict and patient guidance of Teacher Li, my math scores have been greatly improved. I not only fell in love with math class, but also fell in love with Miss Li's "double-faced" personality, so a strict teacher can also make a good student! Although the wrinkles around Miss Li's eyes are increasing day by day, my love for her is getting deeper and deeper.

Not long ago, I stepped into the door of learning in the sixth grade.

Soon after school started, I met a math teacher who made me respect and fear-Teacher Xie. Teacher Xie's class is very interesting, and there is laughter in every class. Teacher Xie taught me a lot of knowledge: understanding of gardens, percentage application problems, transformation of circles, comparative knowledge and statistics of circles. I know that a circle consists of three parts: the center of the circle -O, the radius -R and the diameter-D. In the future, I will look at some other deeper questions and try to answer them. I am not proficient in answering percentage application questions, so I have to do more questions that I don't understand.

I hope that in the sixth grade, I can "but as long as you go up a flight of stairs, you can broaden your horizons by 300 miles."

At noon today, I was doing my math summer homework. Writing, unfortunately, I have a problem. I thought about it for a long time, but I couldn't figure out a way. The question is this:

There is a cuboid, the product of the front and the upper two areas is 209 square centimeters, and the length, width and height are prime numbers. Find its volume.

I saw it and thought: this question is really difficult! Only knowing the product of two surface areas, the volume must also know the length, width and height, but there is no hint at all. How does this start?

Just as I was scratching my head, a colleague of my mother came. He taught me to use the idea of equation to solve it first, but I am not very familiar with this method of equation. So, he taught me another way: list the numbers first, and then exclude them one by one. First, we listed a lot of numbers according to the requirements of the topic, such as: 3, 5, 7, 1 1, and then we began to exclude them, and then we found that only1and 19 were left. At this time, I thought: one of these two numbers is the length of the common side of the front of the cuboid in the question; One is the front of the cuboid, divided by the sum of the lengths of the other side (both lengths are prime numbers). So, I began to tell which number these two numbers were.

Finally I got the result, which is 374 cubic centimeters. My formula is: 209 =119 = 2+171× 2×17 = 374 (cubic centimeter).

Later, I checked this problem with what I learned this semester: prime factor decomposition, and the results are exactly the same.

I am happier than anyone to solve this problem. I also understand the truth that mathematics is full of mysteries, waiting for us to explore. Yesterday, my grandma and I went to the drugstore and bought two boxes of pills-two boxes of stomach Shu Ning, one box of 52 yuan and one box of 26 yuan. Grandma gave her 100 yuan, and the shop assistant gave it to grandma 48 yuan. After I found the change, I calculated it with decimal addition and subtraction. Grandma can also pay like this: 1. Give it to 50 yuan, the shop assistant, and then give it to 10 yuan for 8 yuan. If grandma has change, she can pay 50 yuan first and then 2 yuan. By buying medicine with grandma this time, I know that mathematics is closely related to our lives.

Yesterday, I got 95 points in the math tutoring exam. I made a mistake in filling in the blanks and writing questions. The teacher reviewed the fill-in-the-blank questions for us before the exam. I didn't recite it carefully, but I remembered it carefully. I was thinking about something else when I recited it, and I didn't remember it at all. So when I took the exam, I couldn't remember it anyway, so I just filled in the numbers. I didn't see the meaning of the title clearly, so it was wrong to write "X" as "+". This grade, the first 1 question is because my attitude is not correct, and the second question is because I didn't review it carefully. I will definitely do these two things in the future, but I can't be careless. Teacher, I can't get satisfactory results in every exam. Since I took interesting math, I understand that the most important thing in learning math is understanding. It's no use just copying other people's answers. It's no use copying them. So I will listen carefully in the future and strive for excellent results.

Today, after I signed up for school and went home, I wrapped the book cover and began to calculate the cost of this semester.

The first is tuition. Tuition fee is 4 10 yuan, plus drinking water fee in 20 yuan, 430 yuan. Next, the charge of the Olympic Mathematics School is 180 yuan. It is estimated that the bus fare is in 20 yuan and ***200 yuan. There is also money to buy exercise books: 2 copies of "Classpass" 2 1.5 yuan; English practice 1 9.9 yuan; 2 copies of Examination Paper Course Pass 15.9 yuan; "Jiangsu Big Test Paper" 3 copies 2 1 yuan. 21.5+9.9+15.9+13+21= 81.3 (yuan).

Study fee: 430+200+81.3 = 711.3 (Yuan).

Living expenses: I will drink about 5 cases of milk this semester, 5×30= 150 yuan. Every meal is about 2~3 yuan, including 2.5 yuan.

2.5×3×30×5= 1 125 (yuan). "What else?" I bit my pencil and said to myself, "and your school supplies." Hey, mom's home. Yes, and school supplies.

School supplies: a pencil-box 8 yuan, a pencil-box 3 yuan (very cheap, clearance goods), six pencils 3 yuan, an eraser 0.5 yuan, two triangular rulers 1 yuan, two mechanical pencil 5 yuan, 8+3+0.5+ 1+5=20.5 (yuan).

Total expenditure: 711.3+150+1125+20.5 = 20xx.8 (yuan).

Wow, I didn't expect that I, who usually don't spend much money, would ask my parents to give me 20xx.8 yuan money for a semester. It seems that I will save money!

I did badly in the fifth grade math exam. At first, I comforted myself that the teacher was not teaching well. But then I found out that I was deceiving myself. The teacher is not careless with us, because the teacher is a rare good temper, saying that we dare to push our noses and face, which leads to unsatisfactory results.

In the sixth grade, there is a new teacher-Miss Huang. TA gives people the feeling of being kind and strict; Very humorous and boring. TA is not tall, but I have a feeling that she is very tall. TA's class is very good and clear. But I speak a little fast and think slowly. So sometimes I can't keep up in class. TA felt very serious when she first came, giving people a feeling of being inaccessible. But since what happened later, I have changed my opinion of her from the bottom of my heart.

In math class, we are writing math problems. The teacher corrects math homework on the platform. Suddenly I heard the teacher calling my name. I thought to myself: this is over. Nine times out of ten, the math teacher stopped his name and wrote the wrong question, and this math problem is particularly simple. If I'm wrong, can the teacher leave me alone? I went up to have a look, and it was! And my mistake is actually about the original question! Regret and fear in my heart, bowed my head and was scolded. Unexpectedly, the teacher said gently, "It doesn't matter if you make a mistake this time. Pay attention to it in the future and change it quickly with a pen!" " I suddenly felt a warm current in my heart, and I had an impulse to cry.

Thanks to such a teacher, my grades have gradually increased from failing to more than 80 points, and this time I got 95 points, which is all due to the teacher. I like my math teacher more and more now, because TA is really a good teacher!

In daily life, many things are inseparable from mathematics, which shows how close mathematics is to our lives!

Once, my father and I went to buy carpets and came to the store. My father chose a color. This kind of carpet has two shapes: round and square. The waiter told us that the perimeters of these two carpets are the same, both of which are 12. 56 Deutsche Mark. Dad said, "They are all the same size anyway. You choose! " I quickly shouted, "I'll do the math!" "After that, I asked the waiter for a pen and paper, and calculated the area of the circle with rapt attention according to the method taught by the teacher.

To calculate the area of a circle, first find the radius of the circle: 12. 56÷3。 14=2dm, area: 3. 14×2×2= 12。 56 Deutsche Mark. Square length: 12. 56÷4=3。 14dm, area: 3. 14×3。 14=9。 8596 Deutsche Mark. "Even if the circumference of a circle and a square are equal, their areas are not necessarily equal. It is more cost-effective to buy a round carpet than a square carpet. " I talked with my father endlessly, and my father was dumbfounded. The waiter on the side also praised me for being smart. I don't want to mention how happy I am.

Mathematics is to use it flexibly and connect with the reality of life. Only by mastering the knowledge of mathematics can mathematics serve our lives better. So we should learn math well and make math a good helper in our life.

During my primary school career, many teachers taught me. But in my impression, Mr. Fu, who taught us mathematics, left a deep impression on me.

Teacher Fu is an excellent young female teacher with good facial features. High nose, big eyes, small cherry mouth, looks very quiet. She works hard and is not careless at all. Of course, she is also kind and tolerant to her classmates.

I remember once, Mr. Fu asked a classmate to do a problem in front. This classmate calmly walked onto the platform, picked up the chalk and looked at the problem seriously. After a long time, the classmate's forehead oozed a lot of glittering and translucent flash bodies, and his hands kept rubbing the corners of his clothes and sometimes scratching his head. Just when I guessed that he must not know the problem, I saw Mr. Fu pass by and said kindly, "Don't worry, take your time." Hearing the teacher's encouragement, he nodded confidently. Sure enough, with the teacher's encouragement, a miracle happened. As soon as his eyes lit up, he quickly wrote the complete steps on the blackboard. Teacher Fu looked at his problem-solving process, nodded, and looked at him back to his seat with a smile.

I remember that time, it took our class several weeks to get a flying red flag, and all the students cheered. Of course, I am no exception. Even in class, I didn't calm down. I also whispered to my classmates and was discovered by Mr. Fu. Fu gave me a look, but I still shared my happiness with my classmates and didn't care about Fu's affectionate eyes. After school, Mr. Fu called me to the office and told me, "Listen carefully in class, don't live, and don't do some related questions." I didn't say you were afraid of losing face in front of your classmates just now ... "In fact, I knew why when Mr. Fu asked me to go to the office, and I couldn't wait to find a crack in the ground. I have apologized to Mr. Fu in my heart. Now I sincerely say, "Thank you, Mr. Fu! You taught me self-discipline. "

This is our conscientious, careless, kind and tolerant math teacher.

Mathematics is the eternal power in my heart!

Teacher Zhao asked us to write about our experience and difficulties in learning mathematics today. Today, I just want to talk about my feelings and thoughts in the process of learning mathematics. I am a boy, mathematics should be my hobby, but I have never been interested in it, always afraid of it, and lack confidence! But now I want to tell you loudly, "I'm not afraid, because I have mastered the method, and my math will get better and better!" " This is what my mother often says to me. What is the method? Don't worry, let me tell you slowly:

The first thing is to do a good preview: from the fourth grade, both Mr. Guo and Mr. Zhao have paid more attention to previewing this assignment. Although some students think that preview is nothing, now they mainly study the knowledge in books, and preview is useless, then you are wrong! Self-study in junior high school is very important. Every time after class, whether you understand it or not, the teacher won't tell it again. So it is very important and necessary to preview before class. Preview well before class, let yourself have a deeper understanding of the new knowledge to be learned, and attend the class with questions, so as to give full play to the 40 minutes in class. Then there is a good lecture in class: this is explained by my personal experience. According to my mother, when I was in the second grade, the school once organized parents to attend classes. My mother said she sat in the back and looked at me with her eyes. I can still listen carefully for the first five minutes, and I have been doing little tricks for the rest of the time, either playing with pencils or playing with pencils. After a class, I only listened to the class for five minutes, and I played for the remaining 35 minutes. Now with the help of teacher Zhao, the quality of my lectures is high, and my academic performance is naturally improved! From this incident, we can fully explain how important it is to pay attention to lectures in class!

Then there is consolidating knowledge: doing homework is a good way to consolidate knowledge. I also want to use my personal experience to tell you that when I studied percentage in the first half of the fifth grade, I didn't understand it in class because I taught too fast, so I couldn't write my homework. I should have asked my teacher or mother, but I was in a hurry to go out and play, so I was too lazy to copy other people's homework to cope. I'm sure you're wondering, how did you get caught? Because my mother is completely familiar with the way I solve math application problems-I usually solve problems step by step. My classmates who copied my homework are used to solving problems in a continuous way, and my mother saw through my cleverness at a glance! I tried to hide the truth, but my mother's eyes were like the Monkey King's "critical eyes", and I saw through the trick of this "little monster" at once. My mother said to me earnestly, "it doesn't matter if you make a mistake, son." It is important to have the courage to admit it. " My psychological defense line was suddenly broken-I told my "little secret". After that, I only had one feeling in my heart, cool! I told my secret story, which made a huge stone in my heart fall to the ground!

My math scores have been greatly improved this semester! Because since that incident, I know it is shameful to copy other people's homework, and it is even more shameful to copy the answers! It doesn't work at all, because I still can't Here, I would like to advise those students who are still copying answers to finish their homework, please tear up the answers! Get rid of the trouble of copying homework! Let yourself really grow up! Finally, I think it is also important to solve the difficulties in time: I didn't learn math well at first because I didn't learn it in time, which was caused by accumulation. This year, my mother focused on my math. She checked my homework every day. As long as there is anything I won't do, she will tell me again in time until I really understand! The day I first learned the surface area of a cylinder, I didn't understand it, and I couldn't do a lot of homework. I told my mother after work, and she said, "It doesn't matter if you don't understand!" Don't do math yet. After you finish the rest, mom will tell you again, and then you can do your homework. "In this way, after two days of hard work, I have completely mastered the surface area of the round body. With the help of my mother, I feel that I have learned everything this semester and it is not difficult to do my homework. My mother always tells me what I did wrong first, so that I can correct it, and then gives me three more questions with the same difficulty on a piece of paper, just changing the number and letting me do it again. If I do it right, she will put a big tick on the question and write a big 100 mark! Give 100 points for everything you do right! Three is three 100. This has increased my confidence! And it's amazing that my interest is getting stronger and stronger! Thanks to mom for this good method! Do you think it's good to finish my story? I hope we can work together to create better results!

Mathematics is an unusual knowledge, it is not a boring calculation in textbooks, nor is it a boring number in people's impression; On the contrary, it permeates our daily life subtly and widely. Don't you believe it?

As soon as I open my eyes in the morning and look at the time, "Math Day" begins!

Many things we come into contact with in our daily life contain mathematical factors. For example, before farmers harvest crops, people should accurately calculate the harvest time to ensure that the grain is harvested before the arrival of bad weather. When brewing beer, the technicians in the brewery need to accurately calculate the fermentation and cooking time of each batch of wine to ensure the best taste of the finished beer.

Mathematics is like an invisible friend. Even when we are asleep, there are still thousands of cells in our brain.

Mathematics plays an irreplaceable role not only in our daily life, but also in public welfare activities around the world. In South Africa, on average, more than 200 babies become AIDS patients through mother-to-child transmission every day. Accurately mastering their life data is conducive to the rescue of this special group.

From specific individuals to transnational rescue operations, from astronomy and meteorology to geography and ecology, it can be said that the life of each of us is also the life of mathematics; Mathematics in life is really living knowledge.
