My family is a warm family of four, including my father, mother and brother. My family lives in the west unit of a scenic family on Huaguang Road 12XX, 100 square meter, with two rooms and two halls.
My home is a living room of 20 square meters. There are three mahogany sofas in the living room, one for three people and the other two for one person. In front of the sofa is a coffee table with a length of 1.2M and a width of 0.6m There are many fruit snacks on the coffee table, which I like very much.
In front of the coffee table is a flat-panel TV with a length of 0.95M and a width of 0.5M m. After finishing my homework, I turn on the TV and watch my favorite cartoon-Pleasant Goat and Big Big Big Wolf.
On the left of the living room is my bedroom. The floor of the bedroom is 5.6 meters long and 4.2 meters wide. My bedroom has a desk with many books and review materials, and a 14 inch red notebook computer.
There is a piece of wood crawling up and down on the bed behind the desk. Bed length is 2M, width1.2M, bed length is 2m, width1.2m.. When I am tired, I will lie in bed and rest. At night, I will sleep peacefully here until dawn.
Out of the bedroom is a rectangular kitchen. Whenever I am thirsty, I take out my drink from the refrigerator. The refrigerator is 0.8 meters long and 0.5 meters wide, which is very small.
I like my home very much. My father, mother and brother all love me very much. I grew up happily in this family.
B.the 200-word composition of the math star in our class
Who studies best in our class? Of course Liu is. All the students in our class will answer in chorus. Yes, the performance of Liu's children's shoes in our class is really unparalleled. Her academic performance is always among the best, especially Chinese, which makes me especially admire.
I remember that morning, all of us were taking the mid-term Chinese exam in full swing. It hasn't started yet. Everyone is doing the final review seriously and wants to get a good grade in the exam. At this time, we heard three whistles coming from outside and started the exam. We quickly picked up the pen and began to answer questions. Because the test paper has been handed out, we have read it and have a good idea, so now we just need to write the answer.
In a short time, the paper was finished. I checked it carefully again and began to write a composition. "Ha ha, God help me!" "After reading the requirements of the composition, I am secretly glad. It turns out that I am going to write "growth" this time! Because the format of the autobiography I just finished a few days ago is almost the same as that required by Growing Up, I changed the title and slightly changed the sentences in the article, and it was almost finished!
After a burst of crazy writing, I finally finished my composition. I rubbed my sore finger and took out my watch. There is still half an hour, and the road is still long. I looked around again, and more than half of my classmates didn't finish it, including Liu Yiyuan. "ah! Why didn't Liu Yuyuan finish it? " It occurred to me that Liu was very quick when he did his homework or did other things. Why did she write so slowly this time? Forget it, check it quickly.
Twenty minutes passed like this. I checked it two or three times and found many typos. It seems that although I write too fast, the correct rate is not necessarily high. At this time, I saw Liu finally put down his pen and began to check it. "Her score should not be too high this time, because she writes a little slowly, so the inspection time will not be too long." I thought to myself. "DuDu"
On this day, Mr. Kong came to the classroom with a stack of papers. Suddenly everyone quarreled and the brushing stopped. I even saw some students shaking. It turns out that Mr. Kong has told us that the results of this exam are not ideal, and students who do badly in the exam should do more homework. Finally, the paper was handed out and I looked at the score-90. Suddenly I heard Liu Yiyuan sending it over there. Alas, it goes without saying that Liu got high marks again. Why did Liu write so slowly? After checking several times, his score was still so high. At this time, I remembered what the teacher taught us: "As long as you do the questions carefully and think clearly about every question, you will get 80% right the first time, and you won't have to check too many times in the future, and your score will not be low." .
This is Liu, a talented woman in our class. How's it going? Now you admire her, too.
C. the composition about mathematics is about 200 words.
A little experience in mathematics learning
Next, I want to share with you my own little experience in math learning.
First of all, I think learning should have a good foundation. As we all know, high-rise buildings cannot be separated from a solid foundation, especially learning. Therefore, it is necessary to define the concept in the book at ordinary times, and if you pay attention, usually when you encounter a problem and find it difficult, when you consider it from the perspective of definition, it will often have unexpected effects. I think all these prove that the basic things are really important!
Second, we should always sum up our studies and take them seriously. We all know that there are many more courses in universities than in high schools, and they are making rapid progress. Since then, we have learned more and more, and we feel confused. This requires that you must take time to review and summarize yourself after class. Make knowledge structured and systematic, so as to achieve the purpose of memorizing by heart. So that we can use it easily.
Third, we should master the methods to solve problems, and we should not write blindly. I think my teacher has a great influence on me at this point. When solving problems, he often puts a sentence, that is, "get the problem and see what type it is." I think this is not just a sentence, it tells us a way to solve the problem. First of all, you need to know what problem you are solving and what you are testing. Then you find a way to solve it according to the type, which also shows that our previous summary is very important. I think if we can do this, we should get twice the result with half the effort in solving the problem. I want to thank my teacher, because without my usual careful teaching, I wouldn't have achieved my present achievements.
Fourth, we should exercise ourselves more at ordinary times, take part in various math tests or competitions organized by some schools, departments or other units, and check ourselves. I don't think we have to get anything, but at least we can broaden our horizons and increase some knowledge. Here I want to say to you: the math contest is very good. First of all, pre-test counseling is a review and summary of our previous knowledge. It can make you look back on many forgotten things in the past. Secondly, compared with other exams, math competition pays more attention to the examination of ability and thinking, which is of great help to improve everyone's enthusiasm for mathematics and cultivate their creative spirit and ability to analyze and solve problems! At the same time, it is also a comprehensive examination of what everyone has learned in the past, and it is also very helpful for everyone to understand their own learning situation as a whole! There is also a math contest, which provides a good learning platform for everyone. On this platform, everyone can communicate with teachers online, ask questions from teachers and ask teachers for successful learning experiences, because our teachers are excellent. Of course, everyone can also discuss issues with each other and express their good opinions on the platform. I think these are very helpful for everyone's study! Everyone should try it!
Fifth, I think mentality is also very important in the exam. No matter what the exam is, you should pay attention to it first, which is the most basic and important point. I think if we are not serious at all, we should fail the exam, but we don't have to pursue anything too much, which may also bring unnecessary pressure to ourselves. Also, I think it is inevitable that I will encounter difficulties in the exam. At this time, I want to keep myself calm, analyze carefully and do it according to the method. I can't lose my mind. Even if it doesn't work out in the end, don't care too much about anything. Because you have tried, that's all. In short, it is good to be normal!
Finally, I want to say that we are all excellent. As long as you are willing to work hard, you are the first.
D. An unforgettable 200-word composition for math class.
Unforgettable math classes In my memory, there are many unforgettable classes. These lessons are like countless pearls floating in front of my eyes. They are like a ladder for me to climb and get the golden key. It's hard.
I forgot to write a composition in math class. That was when I was nine years old and was in the second grade. Once, I had a math class. In class, the teacher talked about squares and rectangles. I think these must be common sense of life, I think they must be.
Very interesting, very interesting, right? I looked around again, looking for various figures. I see the table is rectangular, the steering wheel, the sun, the car tires are round and the chalk box is square. When I saw these figures, I was in my heart.
Don't mention how happy you are. I am so surprised. I seem to have suddenly discovered a new continent. It is this math class that broadens my brain and increases my dribbling ability. It's like a golden key to my mathematical knowledge network.
Door, let me more unforgettable, more love network mathematics knowledge, let me worship mathematics more. Comments: There are many unforgettable lessons in a person's growth experience. The author can write a math class and write his own income.
How apt it is to compare this course to a golden key. This article is well written because of its rich imagination, so students should boldly imagine in writing, and imagination is very important.
An unforgettable math class Today's math class is very interesting, because as we all know, the teacher is going to talk about new knowledge again. The math class began, and the teacher said, students, let's open the book to 4 1 page and the teacher will tell you a new lesson.
Knowledge, I'll ask you questions when I'm done. I thought to myself: isn't divisor the whole ten, and quotient the division of two digits? I have already previewed it, and I am sure I will do it right. So I went to class with a smug mood. The teacher gave a lecture.
After that, we were given an examination question on the blackboard. I finished it three times, five times and twice, and gave it to the teacher. As a result, I was wrong, and I thought: How could I be wrong? I am surprised! I read the title again.
The topic is: Zhangzhuang Primary School visits beijing museum of natural history with 492 people, and each bus is limited to 40 people. How many buses do you need? I think that's right. Then I asked some classmates, and they all said they had done something wrong. The teacher saw that we were full.
He said in confusion, your mistake is that you have to take a bus except for the inexhaustible remainder. You left it behind. You should need the 13 bus. After listening to it, we all suddenly realized and said with one voice: So that's it!
A gratified smile appeared on the teacher's face. Through this math class, I was greatly inspired. Whatever you do, you should concentrate on it and be meticulous. Don't be proud and lucky, let alone so-so.
Unforgettable math class From primary school to middle school, I have taken countless math classes. Perhaps attending classes is normal for students, so most math classes, such as passing clouds, have left me nothing.
Impression. However, I still remember the section of the sixth grade last semester, which is unforgettable so far. On that day, Mr. Li held an open class, and all the math teachers and school leaders came to attend the class. We are as usual. After all, open classes are a test.
Teachers' psychological quality, adaptability and teaching level are just props for our students to actively cooperate with teachers, and they will not feel excited and novel. The only thing that can feel a little novelty is that we have changed.
The lecture venue-lecture hall-felt a little more free physically and mentally, and the audience who came to see our performance was a little more. Hehe, that's all. Middle school students wrote "Unforgettable Composition in Mathematics Class". Li Lao, who is in the same class as Ding.
The teacher stepped onto the platform with a big smile on her face. Students, are you willing to help the teacher? Strangely, Mr. Li didn't write the topic on the blackboard, but the unique opening remarks made us feel refreshed. Yes, the students agreed.
Answer loudly. It seems that the enthusiasm of children is actually easy to be mobilized. Curiosity is our nature! However, most teachers do not use appropriate methods to stimulate our competitiveness and thirst for knowledge. all of us
Concentrate on and look forward to helping the teacher solve the problem. Last week, the teacher took the child back to his parents' home. Miss Li told her about her difficulties. Children like small animals, and when they get home, they go for a stroll in the animal pen raised by their grandmother. He found that,
Rabbits and chickens are placed in a row of cages, which is very novel. His grandmother immediately followed him and asked him a question with a smile. At this point, Miss Li paused and saw that we were all craning our necks, which made our appetite rise.
Said slowly: this group of chickens and rabbits, counting from the top, 35 heads, counting from the bottom, 94 feet, do you know how many chickens and rabbits are in the cage? He thought for a long time and didn't give grandma a satisfactory answer. Students, you
Can you help him? Teacher Li's eyes wandered over every student's face again and again, full of encouragement and expectation. The classroom was quiet and the students were absorbed in thinking. He has always been called a mathematical prodigy, just so so.
All the problems that met my difficulties have been solved. At the critical moment, I can't let Miss Li and my classmates down. Especially with so many teachers. I mobilize all the brain cells to make the brain run quickly. Well, I'm really impatient.
I can't eat hot tofu. In the face of this stumbling block, I really realized that the tiger was gnawing at the sky and couldn't eat, and his thinking seemed to freeze instantly and he had no clue. I sneaked a look at several other top math students in my class, and so did they.
Frowning seems to be racking my brains and thinking hard. Perhaps the silence was a little too long, and Miss Li's voice broke the repressed silence.
Sometimes, a person's strength is small and insignificant, but the collective strength is strong. You can try to let other people's wisdom enlighten you. Remember, you are never fighting alone. Miss Li is quiet.
Silent words wake the dreamer. Yes, two heads are better than one, so why don't we give full play to the collective strength? The quiet classroom suddenly became noisy and the students had a heated discussion. How many/much?
Five minutes later, someone finally raised his hand boldly. It's XXX from our class. Encouraged by Miss Li's eager eyes, she bravely stepped onto the platform and explained to her.
Our group regards chickens and rabbits as chickens ... ×××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××
Later, they volunteered to go on stage to explain their ideas. The equation method of XX group is not only novel but also simple. Although the list method of XX group is troublesome and has certain limitations, it is also difficult for a small number of topics.
Very good method, the method of ××× group lifting their feet and walking halfway opened the eyes of the people present ... All roads lead to Rome, and we finally found out the number of chickens and rabbits. Look at the students.
Students * * * into the state, listening to the students enthusiastic, eloquent speech, teachers nodded and smiled, they must think, obedient! Hey! It seems that our parents' little pearls are at a critical moment.
Can also shine. After the last group representative finished speaking, Miss Li smiled and said, Thank you for your help. To the teacher's delight, the students learned to solve their lives by their own intelligence.
In this class, the teacher gave a serious reply to the students and listened to the ideas of the little teachers, which benefited a lot. Shine on you is better than blue! The teacher thanked the students again. Wow, the classroom exploded.
Give a long applause. This applause is sincere respect and thanks to the teacher, and also sincere appreciation and encouragement to myself. Confidence in yourself is the first step on the road to success. We were confident and United, so we succeeded.
Ding Lingling, how time flies! Unconsciously, the class was over, and the students were still immersed in the excitement and thought for a long time. Ah, I hope every math class can be like this! Every class makes us
Remember for life!
E. Tourism Mathematics Composition 400 words-Baidu
I hate math, and it gives me a headache to see those increases and decreases. To this end, I'm going to Math City to make myself smart.
I was shocked when I arrived at the math city. Buildings are full of numbers or arithmetic symbols, and even people's hairstyles and clothes are the same. People shout like chanting, "What is one hundred times sixty-nine thousand?" How much is 9.9 thousand plus 96 thousand? "It makes me dizzy. Just then, a policeman came up and said seriously, "Kid, you have violated Article 26 of the law. For your first offence, you will be fined ten sheets of paper. ".By the way, there is still a time limit of 60 minutes. "Oh, my god, so many! I quickly brought the newspaper and buried myself in writing. Ah! It's really hard! What shall we do? I scratched my ears, scratched my cheeks and sweated on my head. Finally, sixty minutes later, the policeman said strangely, "Where are you from?" ? We are not as stupid as you. Or are you sick? "I said," yes, why don't you take me to the hospital at once? "When I arrived at the hospital, the doctor said very wisely," I know you are from another city. Stop pretending. Ok, I'll prescribe medicine for you, but it has side effects. "Willy-nilly, I don't care. Eat when you catch it. Hehe, I'm getting smarter!
When I got home, I found that I knew nothing about Chinese and English except math. Is this a side effect of that medicine? Hey! I really asked for it!

How to learn math well
Mathematics is the gymnastics of thinking, which is enough to illustrate the flexible characteristics of mathematics. In the college entrance examination, mathematics is often the focus, and learning mathematics cannot be sloppy.
If mathematics is a building, then concepts, theorems, etc. Is its foundation. Imagine, how can a thing grow healthily without roots? Therefore, learning mathematics should start with concepts and theorems and lay a solid foundation. It is more effective to understand a concept or theorem carefully than to do a fuzzy problem.
If you want to be good at math, you should use clever methods. It is important to take part in actual combat and apply what you have learned to practical problems. So as to achieve the realm of "reading thousands of books, writing if there is a god". However, when you push too hard, your movements are often easily deformed, and you can't get much benefit from the chaos brought by the sea. Learning mathematics can sometimes be lazy and follow other people's rules and regulations, and after fully understanding and understanding, it can be used for one's own use. "Other stones can attack jade." This method can often achieve good results. Doing problems is actually a process of understanding the essence through phenomena. Knowing the real intention of the problem and the operation of knowledge in the problem will avoid the loss of "stepping on iron shoes" Learning to summarize is another golden key to mathematics learning. Summarizing each learning stage, summarizing methods and rules, and researching strategies are always more effective than headless flies.
In the final analysis, only when the analytical ability is improved to a certain extent can we be familiar with the topic, but we should also pay attention to the organic combination of hard work and learning methods. Mathematics is also a three-fingered snail-hold on tight.

Math composition-buying vegetables
Today, "children" have the final say. I took the money my father gave me to buy food.
? I came to the vegetable market and wanted to buy food. The food in the market 1.5 yuan, ready to buy 2 kg. But I looked at the food outside the market, which is 1.2 yuan, which is more delicious than the food inside. I was going to buy another catty and fry it at night, which not only bought more vegetables, but also became cheaper and cheaper.
? Then, I go to buy meat. The meat on the market is lean meat, 4.5 yuan is a catty; And the meat outside the market, lean meat less also want to 4.5 yuan a catty, in contrast, of course I choose the meat in the market. So I bought 3 Jin of meat and spent 4.5×3= 13.5 yuan.
I was deeply impressed by buying vegetables this time.

The first article: interesting math problems
There is a lot of mathematical information in life, and we can't live without mathematics at any time!
Speaking of math, I met an interesting math problem today.
Today, while waiting for broadband connection, I sat down and picked up the Happy Life of Garfield, which my mother bought for me. I saw the profile of Garfield. When Garfield appeared on the big screen in 2005, it was his 26th birthday. I told my mother about it. My mother asked me if it was 20 13. How old is Garfield now? As soon as I heard it was a good question, I began to count the years: 26 in 2005, 27 in 2006, 28 in 2007, 29 in 2008, 30 in 2009, 365,438+0 in 2065, 438+03 in 2066 and 32 in 2066. But I think it's too much trouble, just thinking about the difference between 2005 and 13. I can subtract 5 from 13 to know the difference. 13 minus 5 equals 88 years. I add these eight years to his current 26 years, and I will know how old he is now! Eight plus twenty-six equals thirty-four Garfield is 34 years old. I know how to calculate age.
Students, there are many math problems in life. I solved a problem today, and there are still many problems waiting for me to explore and discover. I know, the result is definitely different, just like today's math problem. Learning math is very interesting.
Part II: Measuring the circumference of the TV.
Today, I finished everything and felt bored, so I went to measure the circumference of the TV. When I measured the circumference of the TV with a ruler, I found that the ruler was not long enough. I thought, "What should I do?" Suddenly, I remembered that xu teacher taught me that today we can use lines to measure. With this in mind, I started to do it. I cut a long white line and began to measure. When I was about to finish measuring, I found that the line was not long enough, but I didn't want to cut it, so I thought, "How can I make it simpler?" I went back to my room and picked up a book to read. After a while, I found a simpler method. Because my TV set is rectangular, which only takes up one length and one width. I picked up the thread and measured it. After a while, I measured it. One length and one width is 106 cm, but there are two lengths and widths, so 106 times 2 equals 2 12 cm. It turns out that the circumference of my TV set is 2 12 cm.
I know that when measuring the circumference of an object in the future, if you can think of a simple method, use a simple method.
Article 3: Buy books.
Today, my father and I went to the bookstore to buy books.
We came to the bookstore. I picked out a long-awaited book and went to the cashier. Dad said, "Your book 12.6 yuan, my book 16.3 yuan, I took three ballpoint pens, 1.5 yuan. How much is left in 50 yuan? If you guess right, the rest of the money can buy you ice cream. " I think: 50 minus 12.6 plus 16.3 plus 1.5 times 3 equals 16.6 yuan. I said, "16.6 yuan." "Well, this 16.6 yuan can buy you an ice cream." Dad said happily
When I arrived at the ice cream shop, my father asked me again, "I bought two ice creams with 1.5 yuan and paid 16.6 yuan. How much is left? " I think: simple, 16.6 minus 1.5 times 2 equals 13.6 yuan. I said, "There is 13.6 yuan left." Dad said, "Not bad! Not bad. " I said angrily, "You underestimate me. This is a topic for two years. If I can't even know these, am I still a fifth-grade student? "
Mathematics is inseparable from life.
Chapter four: mental arithmetic
One night in the summer vacation, my mother took me to the 60-episode Lianhua supermarket. I saw so many people in the mall! There are many things in it, such as stationery, food, clothing, alcohol, tobacco, toys and so on. My mother and I bought seaweed, milk, jelly, drinks, shredded squid, shower gel, socks, plums, vanilla and chocolate. Their prices are: 23 yuan, 9 yuan, 3 yuan, 5 yuan in June, 28 yuan, 3 yuan, 40 yuan, 6 yuan, 1 yuan,1yuan. In front of the checkout counter, mother said, "son, can you compare the speed with your aunt?" Calculate the amount to be paid? "I know my mental arithmetic ability is not very strong, so I quickly found a piece of paper and a pen, and calculated it quickly and seriously, but it is still not as fast as the assistant aunt's computer. When I told my mother the result, my aunt had given my mother all the money I was looking for. I checked our calculation results, but I didn't expect to get it right so soon, and my mother praised me, but I know I will improve my mental arithmetic speed in my future study! As long as I work hard, I will make progress.
Chapter five: Mathematical problems in life.
I saw a topic "Mathematics in Life" in my math textbook today. The topic is: "China's population is about 654.38+0.3 billion. If we save 654.38+0 cents per person per day, if so, our country will save about 6.5438+0.3 million yuan. If primary school students need to save about 65438+ tens of thousands of dollars from grade one to college, then this money can be provided to 1805 children who are out of school and have no money to go to school. Wouldn't it be nice to give these money to those people? "
After reading the above information, I thought: many hands make light work. Suddenly I remembered, many hands make light work? Not good, because I thought about it: if this population of about 65.438+300 million wastes 65.438+0 drops of water, then a * * wastes about 65.438+300 million drops of water, then what do you think is 65.438+300 million drops of water?
I did a small experiment: I put 1000 drops of water under the tap and weighed them with a scale. The weight of 1000 drops is 200 grams. I wrote another calculation.
130000000÷1000× 200 = 260000000 (g)
260000000 grams =260 tons
I really don't know, it's shocking: if everyone uses one ton of water a month, then 260 tons of water can be used for two years. I went to ask my father, "How many kilowatt hours can a ton of water generate?" Dad said, "1 ton of water can generate 100 kwh of electricity." This means that 260 tons of water can generate 26,000 degrees of electricity.
Wow! I was shocked at once. 260 tons of water can play so many roles! So we should save all the water now, don't waste a drop of water, we should form a good habit of saving, and we can't waste any more.
