1 xx years, we stepped into the primary school gate and changed many teachers, among which our new math teacher's surname is Gao.
His lectures are interesting, and his voice fluctuates continuously, so that even students who don't like lectures can concentrate on listening to the teacher's wonderful speech. However, this teacher occasionally has a storm. When a student has an accident, his face looks as ugly as a distortion. He will also call his parents and criticize him together. Some people hold grudges and say that he is crazy, but the day after tomorrow is different. That's because he did a good deed, and the teacher quickly praised him.
But he is also very young. At that time, I had a fever and felt very uncomfortable, because I began to cry soon after I graduated from kindergarten. The teacher asked me what was wrong. When he knew what had happened, he took me to the hospital without even calling my parents. He pays all the medical expenses. Later, my mother wanted to thank him and bought him something. He refused: "Give these things to the children, and the children will eat them."
If you were his student, you would like him, too.
Primary school students' math composition 2 is written in letters very concisely, which makes people see at a glance.
But do you know who invented letters to represent numbers? He is the French mathematician Veda. He studied mathematics all his life and made many contributions, becoming the greatest mathematician of that era. Since the Vedic system used letters to represent numbers, many mathematical discoveries have been made and many complicated mathematical problems have been solved.
Letters indicate that numbers are used everywhere in life, such as license plate numbers. As you must know, the rear of every car has a license plate number, and the first few letters of the license plate number indicate which city the car belongs to; For example, Su D said that this car belongs to Changzhou City, Jiangsu Province; Another example: Wan K indicates that this is Fuyang, Anhui, and so on. In addition to the license plate number, you can also indicate the house number. For example, my family lives in Room 302, Unit A, Building 6, so it can be expressed as 6A302, which is really simple, convenient and easy to understand. It is really ubiquitous to use letters to represent things in life!
Math is very interesting. Unlike memorizing English, it depends on your ability to explore. So we must learn math well. Let's discover and explore the mystery of mathematics together!
If you ask me what is my most annoying subject, I will not hesitate to say math. Every day, there are some equations, solutions, sums and laws of several yuan, which make my scalp numb every day. Of course, because of our math teacher, I still keep ahead in math.
My math teacher's surname is He. Although I hate math classes, I never hate math teachers. Sometimes I think math is so interesting, just like the two Ying Ying after He, light and lively.
He Laoshi often gives us problems. Of course, few people know the answer, but she enjoys it. She laughs at the way we scratch our heads, but sometimes I solve some difficult problems, which makes her look at me with new eyes.
I also like the way she lectures. She never writes the answers on the blackboard with textbooks or textbooks, but lets students be teachers. If you have a question, you can do it. Congratulations, you are a teacher. Recalling the first time I stood on the podium, my hand holding chalk was a little shaky, but with her encouragement, I finished the task well. This left a deep impression on me.
This is my math teacher, interesting and strict.
The math teacher is not only our math teacher, but also our music teacher. He is thin and tall, about 1.8 meters. There is also a "small box" on his nose. Its advantages are: wonderful lectures. Disadvantages: Sometimes careless. His hobbies are: playing basketball, singing and playing ice skating. What? How can he care about us? Don't worry, I'll tell you slowly.
Once, a classmate in our class suddenly had a nosebleed. He was in a hurry and sent that classmate to the hospital in a panic. When he arrived at the hospital, he told the doctor about it. The doctor said, "There is nothing wrong with his nose, just a few injections and some medicine." Now he is relieved, but he also asks for leave for that classmate and sends him home.
Another time, a classmate in our class accidentally knocked over a meal at noon. When he walked into the classroom, he saw rice spilled all over the floor. He asked, "Who spilled this?" That classmate said, "It's me." He said, "Why are you so careless? I have five dollars here. Take it to buy food. " When he finished this sentence, the classmate's tears almost fell.
Let me tell you who he is now. He is the math teacher we care about-Mr. Yang Senfa.
My math teacher is a woman, surnamed Xian. She is about 48 years old this year! A pair of bright eyes. A head of black hair with white hair, a big mouth, a pair of small ears, always with a gaudy expression on her face, and a colorful dress.
Teacher Xian is punctual in class and rings the doorbell every time she walks to the door of the classroom. What does she always learn from a class before class? What is its significance? What are its calculation rules? Recall these problems before you know how to do math problems. When we have a new class, we will ask some simple questions for us to do, so that we can remember what we did before. Then the next question is an example of a book. Some students will do it after reviewing before, some students will read books secretly, and some will talk to their deskmates if they can't do it. But all this didn't make Mr. Xian angry, and they patiently taught us how to do it. How to work out the formula of this problem? Some students learn with snow, while others just don't know how to do it. The teacher just said, "If you don't understand anything after class, you can come to my office."
Everyone thought that calling the office was criticized. However, Mr. Xian is not as patient as we thought, and he will also teach these students who don't understand, and make up lessons after class to let those students know more.
I admire Mr. Xian's patience, so I love him.
Math Pupils Composition 6 In every math class, the students in our class are absent-minded, but one of them makes me feel very happy.
Before class, we staged a "Tiangong", and the "Jade Emperor" came ... No, it was the math teacher, Director He. After seeing it, the students ran back to their seats like "the mouse saw the cat" and pretended to be reading. Seeing that we were so nice, Director He asked, "Why don't you stop making trouble? Haven't you had class yet? " As soon as the voice fell, the bell rang, and we were almost deaf with laughter. Director He has to go to class.
Director He speaks slowly in every lecture, sometimes loudly and sometimes quietly, which makes people want to sleep, but there is always a voice that wakes us up-a teacher who always makes boring math classes interesting. There is a picture in the book, which is a pear in a bottle full of water. Naively asked director he, "won't pears rot in water?" Hearing this question, Director He's face tightened and became very serious. We wanted to laugh, but when we saw Director He's serious face, we all dared not laugh, and we all made a flat tire sound. Director He pretended not to hear.
This math class is more interesting than before.
One day, my mother took me to the vegetable market to buy food. There are many dishes and all kinds of vegetables, which are dazzling. Unconsciously, we came to the place where we bought tomatoes. Red tomatoes are really attractive! I said, "Mom, let's buy some tomatoes." Mom said, "OK, but you have to answer my question." 4 kg of tomatoes, * * * 5 yuan 6 jiao, 1 kg of tomatoes? "I thought about it and told my mother that it was 1 40 yuan. Mother asked me how I worked it out. I said to my mother, "Half of 4 kilograms is 2 kilograms, half of 5 yuan's 6 horns is 8 horns of 2 yuan, half of 2 kilograms is 1 kg, and half of 2 yuan's 8 horns is 4 horns of 1 yuan. "My mother praised me for being so smart.
Once, several of our good partners were playing the game of "grabbing the red flag". The rules of the game are blindfolded. Go left for 5 meters, then go forward for 5 meters, then go right for 5 meters, then go right for 5 meters, then go forward for 5 meters, and win the red flag. Several of our good friends had a good time, and it suddenly occurred to us that this game is not just a mathematical problem of route and direction.
I know that mathematics is inseparable from life. No matter what you do or play, there will be math problems with you. There is mathematics everywhere in life.
On Saturday morning, the sun is shining, birds are singing and flowers are overflowing. I opened the book Interesting Mathematics and read it with relish. Suddenly an ancient poem appeared above, and there were so many numbers below, which made people puzzled. I read it with great interest.
The original question is as follows:
White 1 day 2 depends on 3 mountains, 4※5, Huang 6 river, and 7 flows into 8 seas and 9 streams 10. Want 1 1 poor 12 thousand 13 plum 14 mesh 15, more 16 17- 18.
The number corresponding to the first word is 9 times that of the second word, the number corresponding to the fourth word is 1 more than that of the first word, and the number corresponding to the third word is half that of the first word. What is this idiom?
Let me see: the first number is 9 times the second number, so the first and second numbers may be 9, 1 and18,2. If the first one is 9, then the second one is 1 and the third one is 9? 2+4 = 8.5, which is a decimal and invalid. So the first number is 18, the second number is 2, and the third number is 18? 2+4 = 13, the fourth number is 13+ 1= 14. Then write the numbers on it. What is this idiom? A thousand miles a day? .
I finally checked the information and found that it was written exactly the same, and I was immediately elated.
There are so many mysteries in mathematics. I will study hard and explore more mysteries in the future!
Zuo Yifan's tutor Hu
The long-awaited math festival has finally arrived. The students are ready to take part in this interesting little festival. Of course, I am no exception. Small programs that have been prepared for a long time will also perform for you on this day.
The students lined up neatly and sat in front of the stage. The host brothers and sisters kicked off the math festival for everyone. The students performed heartily on the stage. The students in the audience laughed and laughed.
Next, please invite Cai Chenxi from Class Three, Grade One, to perform a math story "Looking at the Moon in Zu Chongzhi" for everyone. After listening to the newspaper behind the scenes, I went on stage. The students in the audience cheered for me fiercely. When the cheers stopped, I started. "Ah ... today's moon is a little rounder than yesterday's ..." Seeing the students listening with relish, I suddenly felt that so many days of practice were finally in vain.
After the performance of the program, I also got the certificate of the math festival competition.
Mom said I did well. I will continue to work hard ...
Math Pupils' Composition 10 One day in the summer vacation, I was doing my summer vacation math homework and was stumped by two questions.
1. There are 30 rows of seats in the east of the gymnasium, which are trapezoidal. The first row of seats 10, the second row of seats 1 1 ... How many seats are there in the east of the gymnasium?
2. There is a string of numbers. The first one is that every number after 10 is 5 larger than the previous one, and the last one is 90. What's the sum of these figures?
Mom came over and asked me what was wrong. I told my mother truthfully, and my mother told me a story after listening. Once upon a time, there was a naughty boy. The teacher doesn't like him very much because he always does little things in class. Once, when the teacher was in class, he was playing tricks again. The teacher asked him to work out a problem from 1 to 100. The teacher thought he might be quiet for a while. But he soon figured it out, and the answer was 5050. The teacher was surprised and asked him how he worked it out. He said: "1+99 = 100, 2+98 = 100, 3+97 = 100, 4+96 = 100, 5+95 =/. The child will become a great mathematician when he grows up. He's gauss.
Through this story told by my mother, I know that when I meet something, I should think more and think more. After a few minutes, the two math problems were solved.

Math Pupils' Composition 1 1 Moore Manor This is a very popular game for our pupils, which can make everyone relax while studying nervously. At the same time, I also found that Moore Manor also contains a lot of mathematical knowledge, and playing games can also improve our mathematical level.
There is no furniture in my house in the game. In the game magazine, I found a set of beautiful small furniture, worth 3300 mol beans. However, I only have 3000 moles of beans. What should I do to buy this furniture?
So I used my brain and found that the mole bean deposit bank has interest, and the interest rate is 3% per day. In other words, my 3000 moles of beans are kept in the bank, and the daily interest is 3000*3%=90 moles of beans.
A day later, my deposit became: 3000+90 = 3090 mol beans;
Two days later, my deposit became: 3000+90× 2 = 3 180 mol beans;
Three days later, my deposit became: 3000+90× 3 = 3270 mol beans;
Four days later, my deposit became: 3000+90× 4 = 3360 mol beans.
That is, after the fourth day, my savings can pay for furniture!
I think there is mathematics everywhere in my life, including games. As long as you use your head, many small problems in life can be solved by mathematics!
Math Pupils Composition 12 Today, my father gave me a task, let me estimate how many people there are in Chen Kai community.
How can I finish this task? You can't let me count them one by one, can you? I've been thinking about it for a long time. If I could know how many houses there are in Chen Kai community, how many families there are in each house and how many people there are in each family, I would come out!
How do I know how many houses there are in Chen Kai community? As I remember, there was a map showing the distribution of communities in Chen Kai. I'll go downstairs and find the distribution map right away. I see that the biggest house number on the distribution map is 16 1. But not all 16 1 buildings are the same height. There are villas, small high-rise buildings and multi-storey apartments. There are three small high-rise buildings, 1 1 floor, each with two house numbers; There are 10 villas with 1 house numbers respectively. The rest are all six-story multi-storey apartments. How many house numbers are there in a multi-storey apartment? It should be calculated as follows:161-3× 2-10×1=145.
Knowing the number and floor of the house, I can calculate the number of households, but how many people should each household count? I assume that there are three people in each household. Total number of villas = 10× 3 = 30 people; The total number of people in small and high floors = 3× 2×11× 2× 3 = 396; Total number of people in multi-storey apartment: 145× 6× 2× 3 = 5220. So the total number of people in the community is 30+396+5220 = 5646.
I feel very happy after finishing my father's task. I feel quite capable, and it is not easy to count the people living in the community.
Math Pupils' Composition13 On July 15, I attended the swimming improvement training class held by Congtai Park Swimming Pool. The swimming pool is just south of my home, about 1000 meters away from my home. It takes my father about 3 minutes to take me from home to the swimming pool by bike, and our speed is about 330 meters per minute.
Training class1* * has 16 trainings, and it takes 160 yuan to buy a student ticket, plus the registration fee of 5 yuan, so the average training fee is about 10 yuan.
After I checked in, I ran into the swimming pool excitedly. Wow! The main swimming pool is very big. It is 50 meters long and 25 meters wide. I calculated with my mouth that its area is 1250 square meters.
The coach began to teach us the essentials of swimming, and then we went into the water to practice. From 8: 30 to 10: 00, it takes about 1 half an hour. I train 16 times at a time, so I always train 24 hours after the whole training.
The coach also asked me to swim 10 times, which is about (25× 2× 10 = 500m). 16 after training, I have been swimming for about 8000 meters.
After the coach's guidance and my hard exercise, my swimming level has been greatly improved compared with last year, and I am determined to continue practicing next year.
Math composition for primary school students 14 We just finished the math exam this morning. Finally finished the exam, the students cheered and some rushed out of the classroom; Some people throw books about; Some people are eating candy ... what a relief! Suddenly, the bell rang and the teacher came in. This time, he is still a math teacher with a test paper in his hand. We were all surprised and asked in unison, "Math teacher, did you change the paper?" The math teacher said kindly, "Yes!" Our hearts were pounding and we sat up straight. The teacher is going to report the scores. Huang Senhao scored 89 points. As soon as I heard that the monitor got 89 points, I thought: Even the monitor got 89 points, didn't I do worse? When I reported for duty, the teacher said, "Ji Ruying 100." After listening to this score, I even jumped to the podium to get the test paper. People asked me how many points I got in the exam, and I proudly replied, "100!" " "When I got home, I told the whole family the score, and the whole family was very happy.
Although I got 100 this time, I won't be proud. I will work harder and strive for better results next time.
Math Pupils' Composition 15 Aha! I made a new friend today-negative number.
Along with negative numbers, there is a brother named positive numbers. Although positive and negative numbers are brothers, they are always incompatible. Negative numbers are usually antonyms of positive numbers. That was not the case. When doing business in a bank, the deposit in 200 yuan is +200, and the withdrawal in 200 yuan is -200. Besides, I saw two brothers when I was watching the weather forecast. The temperature in Hubei is +8℃, and that in Harbin is around -8℃. Alas! What can their good friend "0" do!
This 0 is an old friend of mine. Usually, "0" is always excluded, but with my good friends who are inseparable from positive and negative numbers, they are always out of place when I see them. Positive numbers have a big temper and are stingy. Negative numbers are also pride, and two harmonious brothers turn against each other. "0" became a middleman, and "0" could not treat two brothers equally! "0" is as far away from a negative number as it is from a positive number.
Recently! I make friends with negative numbers and positive numbers. They often come to my house. They can be seen everywhere in my life.
I believe that if you have been swimming in the beautiful and magical ocean of mathematics, you will certainly gain more! More friends!
