The sixth grade math composition is 300 words 1 a math exam in the cram school. I didn't do well in the exam, and I made mistakes in several places where I shouldn't have made mistakes.
On the way home, I clutched the test paper tightly in my hand and felt uneasy. Looking at the scores of the test paper, I seem to hear my mother's criticism and my own sobs. When I got home, I silently put the test paper on the table and stood by myself. My mother looked at me and behaved strangely. She came over and saw my anger rising. One hand rested on her hips and one finger pointed at me and shouted, "Look, you just got this test in a test. What are you going to do in the future? " My eyes are red and tears are swirling in them.
"How many points did Lei Wen get?" Mom held her breath and said.
"9 9 96." I stammered.
"What ninety-six? You only got seventy-five, and you missed twenty-one points! " Mother is pointing at the test paper again. No food tonight. I dare not look at my mother's eyes, only dare to sneak a few glances.
Then grandma came over and touched my head and said, "Try harder next time."
Mom, don't worry about her. You only got so little in the exam. It's no use. "Mother said to grandma.
You go out. "Grandma growled. Mom can't contradict grandma, so she has to go.
Grandma said to me earnestly, "be careful next time, don't be careless, or I will be angry with grandma." Well, go back to your room first. " I nodded and walked silently to my room.
I will do well in the exam next time, so as not to disappoint grandma and mom.
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.
The sixth grade math composition is 300 words, and I 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!
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.
Every time I have a 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!
How thick will a piece of paper be when it is folded in half dozens or hundreds of times? Dozens of meters? Hundreds of meters? How many folds can be as high as mountains?
As we know, the thickness of a piece of paper is generally less than 0.08 mm, assuming that the thickness of paper is 0.05 mm, folding 1 time is 0. 1 mm, folding twice is 0.2 mm ... and so on, folding 10 times is 5. 12 cm. ...
It suddenly occurred to me that I had read a story before. A person puts 2 grains of rice in the first grid, 4 grains of rice in the second grid and 8 grains of rice in the third grid ... the rice in each grid is twice as much as that in the previous grid ... and so on, rice can finally be piled up into a hill.
Isn't origami the same as this meter? I started counting again. Fold 1 times 0. 1 mm, fold 2 times 0.2 mm, fold 3 times 0.4 mm, fold 4 times 0.8 mm … fold 12 times 2 decimeter … fold 22 times 20 9 m … fold 28 times 1342 1. It is more than 4500 meters higher than Mount Everest, which is really an amazing number!
