I used to be a playful and naughty boy who was not interested in learning, but now I am very interested in learning, among which mathematics has become my strong point. What's the matter?
Before I went to primary school, I had never studied mathematics and knew nothing about it. But after studying for a year, I not only learned to tell the time, but also learned how much to give when shopping, how much to take back, and so on. Makes me feel that mathematics is too useful in my life. In this way, I can't sit still in class, and I can always listen attentively and raise my hand actively in math class. Since then, my math scores have been getting better and better, and my scores have come back more and more.
Later, the school opened an interest class in mathematics and Olympics, and the teacher recommended me to participate. The Olympic math class opened my eyes. Li Duo's typical topic "Chickens and rabbits are in the same cage" is very interesting. The teacher asked us to treat chickens as rabbits, put two artificial legs on them, or let rabbits support their front legs. After such a game-like process, the problem is solved.
More interestingly, there is another topic in the mathematical olympiad called "Cattle eat grass". When I first heard this question, I really felt a little strange. There is also "cattle eat grass" in mathematics? The teacher asked us to be farmers, and arranged for some cows to eat the original grass and some cows to eat the new grass. Although it is a bit difficult to count the olympiad, whenever I do it, I always have a sense of accomplishment and my heart is crossed.
How great mathematics is! I believe that this silent mathematics will bring me miraculous happiness and pride.
Today, my grandparents and I went to Qingdao. Our first stop was the beach ... as soon as the bus arrived, I couldn't wait to run to the beach. The blue sea is endless. I took off my shoes and stood barefoot in the sea, feeling the cool water rushing with the waves. I cried and shouted excitedly. It feels great. This is my first time to see the sea. I was fascinated by the endless sea. I feel unspeakable joy and excitement in my heart. The deep blue sea, golden beaches, crowded and happy people, the sea is really beautiful!
At this time, grandpa came over and said, there are so many people today, I'm afraid there must be tens of thousands. Okay, it's big enough here. I thought, yes, how big is this bathing place? So I observed it carefully, and I found that this bathing place is probably a rectangle, and I only know its length and width, but how do you know its length and width? At this time, a row of parasols on the beach caught my attention. Parasols lined up on the beach and stretched out at both ends. The distance between every two umbrellas is basically equal. I walked between two umbrellas first, counted about 50 steps, and my step was about 40 cm. The distance between the two umbrellas is 40× 50 = 20xcm, 20xx cm =20 m, and I ran to the back again.
Wide, it is much easier. It turns out that there is a long rope for warning from the water's edge to the shore, and a small red flag is tied to it every other meter. The small red flag has 30 faces and a width of 30m, and the beach area is1200m× 30m = 36,000m2. I wrote a calculation method for grandpa on the beach, and he nodded straight, and the tourists nearby kept praising me. Today, I not only visited the beautiful scenery of the seaside, but also solved the small problems in my life with the mathematical knowledge I learned. I'm really happy.
My Math Story Composition 3 Math is a very interesting subject.
I often think hard about a topic, but the final answer is so simple. Even if my math score is not one of the best, it can't stop attracting my attention. I remember once, when I was doing my math exercise book, I met a difficult problem. I thought about it and racked my brains, but the problem still couldn't be solved. "Let's give up!" A voice from the heart. "No, I must remember!" I immediately rejected the idea. This voice is full of confidence and strength. The desk lamp is still on, and the hour hand has pointed to 8, but I "swayed" in the chair, and my eyes were shining. I don't understand the concept of time, only know that the immediate problem is waiting for me to solve. I always feel that my math scores will never be excellent, and I always rush into things whenever I encounter problems. But at this moment, I realized the fun of thinking.
Finally, God will repay those who help him! I finally succeeded, I am very confident, even 100% sure. At this time, my heart is sweeter than honey, and I keep talking to myself: I am so smart and talented! I rushed to my father's room with my exercise book in high spirits. Once I showed my answer to my father and asked him to help me judge right and wrong. Dad said it was wrong after reading it, and it was not the right answer. As soon as my father spoke, he sent me from heaven to hell. All my previous efforts were in vain, but I still didn't choose to give up. Back to my room, I started another journey of never stopping until I reached my goal ~ ~ ~ I have never been so serious about math. At this moment, I want to prove to myself that I can do it. If I can't think of it in a minute, I'll use it for an hour. If I can't figure it out in an hour, it won't work in two hours. There are still four hours, five hours, six hours to the next day. Actually, the answer I handed in today is the answer I showed my dad.
It took me a long time to determine the answer. At this moment, I realized why my father said I had done something wrong. He wants me to learn to distinguish right from wrong by myself, and let me work hard to determine the final answer. I suddenly realized. I fell in love with math and thinking. In my heart, this is fun!
At the weekend, my father and I came to the new house being renovated. The decoration master said to his father, "Boss, our preliminary project is almost finished, and we are going to lay the floor tiles. Please buy them. " "You tell me how big is the area? I am going to prepare "; Listening to the conversation between my father and the decorator, I asked cheerfully, "Dad, I can already calculate the area. Let me help you calculate. "
I measured it with a ruler. The length and width of the living room floor are 6 meters and 4.5 meters respectively, and its area should be 6X4.5=27 (square meters). I proudly told my father that buying 27 square meters of floor tiles is enough. Dad smiled and asked me, "I bought a square floor tile with a side length of 6 cents." Can you tell my mother how many to buy? "
I suddenly froze, thought for a while, and suddenly thought that the area of each floor tile should be calculated first, and then the living room area should be divided by the area of the floor tile. So I used small stones on the ground to calculate the area of each square floor tile with a side length of 6 cents: 6x6=36 (square decimeter) =0.36 (square meter); 27 square meters divided by 0.36 square meters is about 75, so 75 yuan should be enough. So I said to my father loudly, "Dad, 75 yuan will do."
Dad praised me for knowing that I had applied what I had learned to my life. Later, my father took me to the store and bought 80 floor tiles. I asked strangely, "Isn't it 75 yuan? Why buy five more? " Dad told me that there was wear and tear during the construction. If the size is not suitable when cutting carelessly, we need to cut again, so we should buy more products than the actual quantity.
Oh, I see. When applying mathematics knowledge to solve practical problems in life, think more about the actual situation in life, so that mathematics can really be close to our life.
My math story composition 5 My math teacher once said, "Mathematics comes from life and is also used in life."
I seem to have been partial to mathematics since kindergarten. There is a simple reason. At that time, when I was young, I thought it was easier to write numbers than to write. The reason may be "laziness" Later, I unconsciously became interested in mathematics. By the first grade, my enthusiasm for learning mathematics was even stronger. Because I do math problems accurately and quickly, I am often praised by teachers, so I not only actively preview what I want to learn the next day, but also consciously read synchronous textbooks.
I have always thought that learning mathematics is not a difficult thing. As long as you listen carefully and practice hard in class, you can learn well. I like math because it can make me feel successful and happy. I also explore some very interesting math problems. In short, "I am very interested in mathematics."
My mother bought some vegetables from the vegetable market this morning. Seeing that my mother bought my favorite tomato, I washed it quickly. When I was about to eat, my mother asked me, "Son, if you want to eat tomatoes, answer me a question first." I listened and said, "Well, ask anything." My mother saw that I was very angry and said, "Then I'm welcome!" " My question is simple, that is, let you calculate the volume of this tomato. "After listening to this, I thought," This is not necessarily too simple. Take a rectangular container, measure its length, width and height, then add water, measure the height of water, then add tomatoes, and then measure the height of water and multiply it by the length and width to measure the volume of tomatoes. "
I first found a useless plastic box in a small room and measured its length and width, all of which were 9 cm. Then I put it in water, and the height of the water is 10 cm. Finally, I put the big round tomatoes in the water. I took a ruler and measured the height at once. I thought, I want to know the size of the tomato. I know its length, width and height, which is 9 cm. The volume of tomatoes = the volume of water rising, and the volume can be calculated. The volume of tomatoes is 9×9×6=486 cubic centimeters. I told my mother what I thought. My mother was very happy after listening to this and rewarded me with a tomato.
Of course, you should also be interested in learning math. Interest is the best teacher. Mathematics is a wonderful big garden, which always contains surprises, depending on whether we can dig up the treasure!
