Fourth grade mathematics composition

In daily study, work, and life, everyone must have come into contact with composition. Composition is a narrative method that expresses the meaning of a theme through words through human thought consideration and language organization. How to write an essay to avoid making mistakes? Below are 6 fourth-grade mathematics compositions that I have compiled for you. Welcome to read and collect them. Fourth Grade Mathematics Composition Part 1

Each of us has a pair of dexterous hands, and everything seems to be inseparable from it. In kindergarten, the teacher taught us to use our fingers to count. At that time, we often used the ten fingers of each hand to calculate addition and subtraction within 10. Now, although we don't need to use it to calculate simple addition and subtraction, sometimes we still use it when doing some math problems. For example, we used it to help us when we were learning years, months and days in the third grade. Remember Otsuki and Otsuki.

Once, when I was watching "Fun Mathematics", I encountered a question: a child was counting fingers. He counted in this order: thumb, index finger, middle finger, ring finger, little finger, ring finger, Middle finger, index finger, thumb, which finger is the 36th?

I was a little confused at first and didn’t know how to start. Suddenly, I thought about my own hands, why not break them with my fingers? So, I used one hand to break them according to the requirements of the question. After a while, I found the answer: the 36th finger must be the ring finger. But I was not satisfied, because I thought, what should I do if the question asked which finger the 360th finger is? I thought, this question must have a pattern, what is the pattern?

I picked up the pen and started writing on the scratch paper. Finally, I found the correct solution: if you number all the fingers, and then look at how many are in one cycle, and then divide 36 by the number of fingers in one cycle, the remainder will correspond to the number of that finger; there is no remainder, It means that the number of that finger is equal to the divisor. I wrote on the scratch paper: 1 thumb, 2 index finger, 3 middle finger, 4 ring finger, 5 little finger, 6 ring finger, 7 middle finger, 8 index finger. It is a cycle of 8 fingers. I used the method of dividing 36 by 8 equals 4 and the remainder is 4 to get the remainder, which is 4. The ring finger is numbered 4. The answer came out, number 36 is the ring finger. Haha! This is completely consistent with my previous experiment. In addition, I also found that the index finger, middle finger, and ring finger appeared twice in one cycle, and only the thumb and little finger appeared once.

After completing this question, I not only felt the wonderful use of my fingers, but also deeply realized the charm of mathematics. In fact, some math problems may seem difficult, but as long as we think seriously and carefully and make full use of everything around us, we will definitely solve them. Fourth Grade Mathematics Composition Part 2

On Wednesday, the weather was not good and very cold. The beautiful Teacher Ding asked us to play the "dice game". When I heard this game, I thought: "Why does the teacher let us play dice? This is a math class!" Teacher Ding continued: "This time the game is not about playing dice." Instead, one learns, first one person takes a dice, two people form a team, then rolls the dice to form a three-digit dividend, then rolls the dice again to form a two-digit divisor, and then calculates it vertically.”

Hao Yiwei and I were in a group. The teacher first handed out a piece of white paper and we started playing games.

I roll the dice first, my number is fifteen, Hao Yiwei’s number is seventeen, and our dividend is one thousand five hundred and seventeen. I rolled the dice again, the number was thirteen, Hao Yiwei's number was one, and the divisor we formed was one hundred and thirty-one. After a horizontal pattern was laid out, we started writing the vertical pattern. We quickly figured out the answer. The answer is that the remainder of eleven is seventy-six. We then did a lot of questions, most of which involved dividing four-digit numbers by three-digit numbers.

After a while, Teacher Ding asked Li Jiaying and I to change places. I went to teach Li Jingru and Guo Zihe, and I asked her to do one course each, taking turns. Li Jingru is not very fast, but she is very smart and can almost complete a question by herself. It was Guo Zihe's turn to do it, so I taught her a few questions and she got it.

I think this dice game is very valuable, because this game can make us better at mathematics, and also allows us to learn while playing. I hope to do more of this interesting game in the future! Fourth Grade Mathematics Composition Part 3

I remember on the first day of junior high school, I really had no interest in the subject of mathematics. However, since I took Teacher Qian’s math class, I gradually fell in love with math class.

Teacher Qian wears a pair of thick glasses, has sparse hair and is slightly bald. At first glance, many people will think that Teacher Qian is an unsmiling and silly scholar. But whenever it gets cold, he often wears his shirt outside his shirt, looking very stylish.

Teacher Qian usually doesn’t like to talk much, but his speech in class is very distinctive. His voice is quiet, but he speaks clearly and his Mandarin is very standard. During class, he often smiles. Teacher Qian also has a unique skill, which is that no matter how profound and difficult the theory is, it can be expressed through humorous language.

The atmosphere in Teacher Qian’s mathematics class is often the best. We can easily master the knowledge points, and the students are willing to actively raise their hands to speak.

I like Teacher Qian’s class and I can’t help but like mathematics. When faced with a difficult problem, I no longer felt annoyed. I gradually learned to think carefully about the knowledge points taught by Teacher Qian in each mathematics class, and I also had deeper thinking and analysis.

Thank you, Teacher Qian, because of your teaching, my mathematics class has become more interesting. Fourth Grade Mathematics Composition Part 4

There were cheers on the playground: "School has started, and I can play with my classmates again!" I was in a large truck, ready to welcome the new little master. Some of my companions and I were moved away by a classmate. When we arrived in the classroom, we were sent over one by one by classmates and came to the hands of my little master. My little master said: "Wow! It's a brand new math book!" It turns out that I am a math book! At first, I thought that books were all books, but books did have categories after all!

I was put into the belly of a big guy by my little master. Am I going to be eaten? I didn't expect that it was my house, so I started to break out in a cold sweat. After entering, I realized that it was a luxurious villa. I couldn't help but say: "You are so beautiful!" The villa said: "Of course, I am the little master. What a nice schoolbag I bought for a hundred dollars!” “Oh? What’s your name?” I asked. It replied, "Yes, I am the famous schoolbag invented by humans! It is specially designed to hold all kinds of books like yours!" "Oh, so that's it. My name is Mathematics Book, and I specialize in tutoring the little master in learning mathematics. book." it said. After a while, two more partners, Chinese books and English books, appeared in the belly of the schoolbag. Then, art, music, science, and moral books also came in. Everyone tried their best to help the little master learn, and we formed a team. , called the "Literary and Ink Alliance", so everyone performed their duties and took care of one subject. The little master also bought us new clothes to wear, and when he got home, he put us on the desk, so we taught the master every day People learn.

Time flies like an arrow, and the sun and the moon fly like a shuttle. In the blink of an eye, half of the semester has passed. My master no longer likes me, and he graffitied on my body, making me dirty all over. One semester is almost over, and my body is scarred, not neat and beautiful anymore.

After the little master passed the exam, he immediately threw me and other scarred companions into the trash can. How I wish I had another little master who loves me!

One day, a child came over, picked me up from the ground, and sent me and my companions to the printing factory to give me a new look. So, our "Literary and Ink Alliance" has a new one, I love my little master.

How I hope humans can take good care of our books! Fourth Grade Mathematics Composition Part 5

On campus, most of the time is spent in class. Many students think that class is boring. But I think our math class is very interesting.

Our math teacher is not unusual. She has a flat nose, slightly dark skin, and a bit long hair. But the classes she taught were very interesting, and I looked forward to her math classes every day. Because in her math class, there are sometimes many rewards or words of encouragement. Taking her math class has become a major interest of mine.

For example, when she was talking about the meaning of 0, I told a male classmate that if I had two candies and gave both to that male classmate, then the other There is no sugar, and his sugar count is 0, which means he is a "pauper". What she said made me and my classmates burst into laughter, and a few of them even cried out that their stomachs hurt. Another time

There was a classmate who seemed to be overly ambitious. He openly provoked the math teacher in class, made a lot of noise in class, and fought with his classmates. The math teacher was like air. . This time the math teacher was really angry. After she used the long-lost tricks such as "Hedong Lion's Roar" and "Eighteen Dragon-Subduing Palms", the student was really scared. This also made us understand mathematics. The teacher is not a "paper tiger", but a "generation of heroine". In the following classes, almost no one dares to cause trouble.

Time flies, half the semester has passed in the blink of an eye, and it’s time for our math teacher to say goodbye to us, because she came from the university’s teaching team, and now it’s time to go back. We all can’t bear to leave her, but I have no choice but to watch a new math teacher come in the new semester.

Oh! By the way, I forgot to tell you her name. Her name is Su Yanan. Fourth Grade Mathematics Composition Part 6

Today, my sister, my mother and I went to my uncle’s house to play. As soon as I entered the door, I saw that the coffee table was filled with many fruits, much more than before. I walked to the coffee table and saw a math question on a piece of paper. It said: There are 30 grapes, 19 bananas less than grapes, twice as many oranges as bananas, and 3 more apples than bananas. Is there any question? How many fruits?

I picked up a pen and a piece of scratch paper and wrote on it that bananas are 19 fewer than grapes. The formula is: 30-19=11 (roots); oranges are twice as many as bananas. Times, that is: 11 times; 2=22 (pieces); there are 3 more apples than oranges, that is: 22+3=25 (pieces). In this way, the number of all the fruits is calculated, and then added together to get the number of fruits in one ***: 311+22+25=88 (pieces).

I confidently said to my uncle: "The correct answer is 88." My uncle smiled and said to me: "Yes, it is 88. It seems that this question is not difficult for you!" I secretly thought in my heart: To me, this kind of question is like Zhang Fei eating bean sprouts - a piece of cake!

My uncle held another piece of white paper in his hand and said to me slyly: "If you can get the correct answer, I will reward you with something." After I got the white paper, I saw the title above: Mom bought a bottle of drink. Xiao Ming drank 50 ml for the first time, 80 ml for the second time, 90 ml for the third time, 100 ml for the fourth time, and 100 ml for the fifth time. After drinking 200 ml, my mother drank 380 ml. How many ml does this bottle of drink contain? How many liters together? After I read the question, I was secretly happy. Who can't do such a simple question? I picked up a pen and wrote on the scratch paper: 38910200=500 (ml). This is how many ml Mr. Xiao Ming drank. 50380=880 (ml) This is this bottle Total *** number of drinks. So the result is 880 ml, which is 0.88 liters. I held it confidently and showed it to my uncle, who could tell at a glance that I had written 30 instead of 50, so the question was all wrong. My uncle patiently said to me: "The result should be 1000 milliliters, which is 1 liter."

Only then did I understand a truth: You must be careful and careful in everything you do, so that you can do it well.
