1 Every time I sit in the classroom, I think of the teacher standing on the platform. She tries her best to help us correct the test papers and test papers, so that our study will be improved.
At a class meeting, every story the teacher told us included scenes of poor days and the teacher's childhood life. In order to let us study hard, the teacher will tell us many stories at every class meeting.
After a while, I suddenly felt that the teacher was my mother. She loves me deeply, provides me with knowledge and helps us clean the classroom. I really admire you.
I want to say thank you, this hardworking teacher.
My family is a "math" family, not because everyone in my family is proficient in numbers, but because my relationship with my parents can be expressed by some mathematical formulas. Generally speaking, "I = father+mother", because I am the son of father and mother, not only have similar appearance, but also inherit their strong and unyielding character. Although I am a nobody, I am really a member of the family. My parents treat me equally. When I meet things at home, I will be honest with each other, just like a little host.
So, sometimes "my father+mother". Do you know why? Because when my parents were doing farm work, they saw something was wrong, so they discussed with me and asked me how to deal with it. They did as I said. At this time, I feel that I am a teacher and they are like students.
Our family is such a veritable "home of mathematics".
Sixth grade math composition 3 "There is a new math teacher in our class!" "The math teacher in our class is Miss Feng!" The latest news made us very happy. Because I have long heard that this teacher Feng teaches well, it is great to teach our class this time.
Teacher Feng really lives up to her reputation and teaches very well. Every time she attends class, a little joke pops up from time to time. Everyone in Doby makes boring math classes interesting.
Hey! You will ask, "Does Mr. Feng like his works?" Not to mention this: every morning, Mr. Feng takes the notebook of the classmate who did the wrong question yesterday and goes to the classroom to call them to the front and explain them one by one until the classmates can do it.
Teacher Feng is very kind and never hits anyone. She often said, "I am like the Monkey King, and you are like a monkey. The Monkey King has such a good relationship with them. How could he have the heart to hit them? " You will ask, "If someone does a small thing, will Mr. Feng care?" Don't worry, Mr. Feng will reply like this: "Mr. Feng's eyes are so sharp that nothing can hide from the teacher's eyes." After that, Mr. Feng glanced at the classmate again. If you see that your classmates are still playing tricks, Mr. Feng will move the chair out from under the table and say to your classmates, "Classmate, I will show you a sketch. Please don't laugh. " Later, the teacher learned from this classmate's appearance: head down, hands groping around, this classmate saw it, and immediately knew that the teacher was learning his own appearance, so he quickly put things away and listened to the teacher carefully. Students, you see how wonderful Mr. Feng's move is. It not only disgraces the classmate, but also makes him stop making small moves.
After class, the students gathered around to discuss the teacher: someone said, "Teacher Feng treats us as friends, so we should listen carefully." Someone said, "I thought Miss Feng was fierce at first, but I didn't expect her to be so kind and warm my heart." Someone said, "Mr. Feng smiled as soon as he entered the door, which made me feel refreshed at once." Someone said, "Teacher Feng's smile touched me. I must study hard and make progress every day. " Others said it was ┉ ┉.
Students, do you want to know our amiable and humorous math teacher?
The fourth article of the sixth grade math composition read page after page of math problems, and soon fell into deep thought. Time flows away quietly like running water, silently. I'm just wasting it in the math kingdom. Because I just make a fool of myself, and I don't know how to understand and be flexible. Is there only arithmetic in the kingdom of mathematics? No. I can answer for sure.
Finger gently turned a page, I know I was wrong. Mathematics is changeable, depending on how you use it flexibly. I always use that single method. In the past such a long time, I have only one way. I bowed my head and meditated, adding a little sadness to my heart, thinking, Math, how can I treat you like this?
After interacting with mathematics for so many years, I can't help but shed a tear in my eyes when I recall the dribs and drabs of mathematics. If you have a dream, you will wake up peacefully and everything will be the same. Have you ever been willing to stop for a minute for us when you can travel in a hurry? Prosperous through the ages, as thin as dust. We are addicted to fireworks and ignore too much. How much time did it take me to do math? Do you remember those formulas, simple calculations? No matter what happened before, we should be flexible, be good at thinking and be active in the future mathematics kingdom. Time and math have taught me that I can't just wait for an algorithm. Treat it well, and you will like math more and more.
Dear you, do you love math? Do you cherish time? Do you take math seriously? I think you must cherish it, use it flexibly and let it accompany us through bit by bit!
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.
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.
The final result 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!
Sixth grade math composition 7 Whenever I have math class, I can always see his active figure. He is Zhou Ruiyuan, a little expert in mathematics in our class.
Zhou Ruiyuan wears a pair of glasses, which makes him more knowledgeable. I remember once, Teacher Dai asked a very difficult question. It's rare for us to scratch our heads and figure it out. At this time, we were all dumbfounded, and the young master raised his hand and thought, this has stumped 55 people in the class. Can you answer that? I want to see his jokes with schadenfreude, and at the same time, I am full of admiration, because his math scores have always been excellent. He pushed his glasses and said slowly, "We can draw a picture to show the burned part …" Looking at Mr. Dai's face, he showed a pleased expression. Sure enough, he didn't answer wrong.
When he finished answering, we were all shocked by his way of thinking. We suddenly realized and said, "Oh, oh! It turns out that this is the solution. " Awesome, you really deserve to be a little expert in mathematics.
There are three good students on his award certificate, a little expert in calculation ... and he is also a little expert in sports. He won honors for his class in the school sports meeting many times. Really both civil and military!
He has a flexible mind and is not rigid in doing problems. Let's say last time, when I was doing my homework, I saw that the teacher didn't talk about the topic in class. I hurried to ask Zhou Ruiyuan. He frowned at first, and then said to me, "You just need to adjust the radius." I was understood by him. I nodded and said thank you.
How's it going? Math experts live up to their reputation!
What is mathematics? Some students say that mathematics is just some application problems, some students say that mathematics is some addition, subtraction, multiplication and division, and some students say that mathematics is to calculate how much you need to pay for shopping.
What exactly is mathematics? Actually, I didn't know that before. Until today, I attended a "special math class" organized by Bao Xiaoxiao, and I had some ideas about what mathematics really is. The speaker of the event is Mr. Zhang, the founder of the Olympic Mathematics course, the dean of Qiantang University of Arts and Sciences and the gold medal coach of the World Mathematics Team Championship. The first time I saw Mr. Zhang, my impression was as ordinary as my impression of mathematics, but it didn't look special? But why is it called "special math class"?
I sat at the activity site with questions and listened carefully. The original mathematics is: number, number theory, reasoning, geometry, algebra, statistics, permutation and combination, application problems and calculation. One of the most important and common is calculation, which is ubiquitous in life. Calculation is very important, except reasoning, everything else needs calculation. We should not only know how to calculate, but also calculate quickly and accurately. How can I improve my computing ability? Teacher Zhang told us four magic weapons: first, pay attention to mathematics and arithmetic; Second, strengthen oral calculation; Third, summarize the methods and mistakes; Fourth, master calculation skills. Hearing this, I finally understand that students who get good grades in mathematics are not smarter than others, but they have their own clever calculation methods and work hard behind them. How to make the calculation fast and accurate? Teacher Zhang also told us that we should correct the attitude of learning mathematics, practice hard and master the calculation method.
During the activity, the teacher also used many examples of topics to deepen our methods of learning mathematics. My biggest gain is to learn how to skillfully calculate the most troublesome "two-digit times two-digit". It is clear: addition is together, it doesn't matter who is added first, subtraction is separation, it doesn't matter who is subtracted first, the multiple is several times, it doesn't matter who is multiplied first, and even division is the same.
It's really a special math class. Teacher Zhang is unusual. After listening to this special math class, I began to worship math, and I began to worship Teacher Zhang. I'm more interested in math.
From grade one to grade six, there are countless teachers who have taught our class. Besides our head teacher, the math teacher left a deep impression on me.
The math teacher is also surnamed Shen. He is of medium height, with a little silver hair in his sparse black hair and deep eyes under his heavy eyebrows, reflecting an elusive light of wisdom. He always smiles and looks amiable. Once, I finished my homework quickly and stood in front of the homework teams. The math teacher Shen took my exercise book, frowned, gave me a look and gave it back to me. I took the book in doubt, and my heart thumped. It was full of bright red. I went back to my seat and began to correct it, but I couldn't solve the problem. Teacher Shen called me to him. First, he asked me sternly, "How did you do this homework? What a mess! "Then he taught me seriously and marked my mistakes with a red pen." Do you think these questions should be wrong? "My face is hot, because I made some low-level mistakes, and I can't wait to find a crack to drill down. I see, but the teacher left two beads of sweat on his cheek.
When we make mistakes in our homework, Mr. Shen always teaches us kindly. But when we are not serious in class, absent-minded or whispering, we are always extremely angry. I still remember when Mr. Shen first came to teach us, a classmate probably wanted to challenge Mr. Shen's patience. . So when Mr. Shen was in class, he read comic books under the table in private. He lowered his head, and everyone held his head high, which seemed out of place. Shen, an eagle-eyed math teacher, soon discovered this difference. Teacher Shen came up to him and said jokingly, "Hey, what are you studying so hard?" Mr. Shen grabbed the book from his hand and suddenly grabbed his ear. He cocked his head and stood up, blushing like a ripe red apple. Teacher Shen severely warned him to be serious in class and not to desert. This time, as an example, we will never be careless in class again.
The eccentric teacher is sometimes amiable and sometimes extremely strict. However, this teacher left us an eternal memory and a bittersweet life. We really like this teacher and hope that he can accompany us through the last time at our alma mater.
