Learning mathematics should be used in real life. Mathematics is used by people to solve practical problems. In fact, there will be math problems in life. For example, when you go shopping, you will naturally use addition and subtraction, and you always have to draw pictures when you build a house. There are countless problems like this, and this knowledge comes from life and is finally summed up as mathematical knowledge, which solves more practical problems.
I once saw a report that a professor asked a group of foreign students, "How many times will the minute hand and the hour hand overlap between 12 and 1?" Those students all took off their watches from their wrists and began to set hands; When the professor tells the same question to the students in China, the students will use mathematical formulas to make calculations. The commentary said that it can be seen that China students' mathematical knowledge is transferred from books to their brains, so they can't use it flexibly. They seldom think of learning and mastering mathematics knowledge in real life.
From then on, I began to consciously connect mathematics with daily life. Once, my mother baked a cake, and two cakes could be put in the pot. I thought, isn't this a math problem? It takes two minutes to bake a cake, one minute in front and one minute in the back. At most, two cakes are put in the pot at the same time. How many minutes does it take to bake three cakes at most? I thought about it and came to the conclusion that it takes 3 minutes: first, put the first cake and the second cake into the pot at the same time, 1 minute later, take out the second cake, put the third cake and turn the first cake over; Bake again 1 min, so that the first cake is ready. Take it out. Then put the reverse side of the second cake on it, and turn the third cake upside down at the same time, so it will be all done in 3 minutes.
I told my mother about this idea, and she said, actually, it won't be so coincidental. There must be an error, but the algorithm is correct. It seems that we must apply what we have learned in order to make mathematics serve our lives better.
Mathematics should be studied in life. Some people say that the knowledge in books has little to do with reality now. This shows that their knowledge transfer ability has not been fully exercised. It is precisely because learning cannot be well understood and applied in daily life that many people do not attach importance to mathematics. I hope that students can learn mathematics in their lives and use mathematics in their lives. Mathematics is inseparable from life. If they study thoroughly, they will naturally find that mathematics is actually very useful.
2. Give me some short articles about mathematics in life, no less than 400 words. In daily life, everything is inseparable from mathematics, which shows how close mathematics is to us.
For example, mom goes to buy fruits and vegetables, goes to the publishing house to reply to the manuscript ... and so on, all of which need math. There are many interesting mathematics in life, waiting for us to discover and explore.
During the summer vacation, my parents and I went to my cousin's house to play. I was thirsty on the road, so my father had to buy mineral water from the nearby grocery store. There is a rule in the grocery store: if you buy three bottles of mineral water, you can get a bottle of mineral water, and the price of a bottle of mineral water is 1 yuan. When my father saw it, he took out 10 yuan and gave it to the grocery store owner, saying, "The boss bought 10 bottle of water." When I got the water, I drank it hungrily, and soon I drank two bottles. Before I came to my senses, there were several empty bottles. Dad asked me, "Lingling,1how many bottles of mineral water can 0 yuan exchange?" I think: I drank 10 bottle of water, 9 empty bottles were replaced with 3 bottles of mineral water, 3 empty bottles were replaced with 1 bottle of mineral water ... and there were two empty bottles left. I happily said to my father, "Dad, I have worked it out. Yes 14 bottle of mineral water, and there are 2 empty bottles left. " Dad smiled and said, "Think again!" I said thoughtfully, "We can borrow an empty bottle from the grocery store owner and return it to the boss after drinking it. Oh! We can drink 15 bottles of mineral water. " Dad nodded in praise.
Mathematics is to use it flexibly and integrate theory with practice. Only by mastering the knowledge of mathematics can mathematics serve us better. So we should learn mathematics well and make mathematics a good helper in our study and life.
3. The composition of Mathematics in Life is about 400 words. Which big brother is eager to help me learn math in my life?
Today, I saw a lot of people donating money to people who didn't go to school on TV, remembering that there are about 65.438+0.3 billion people in China. If everyone saves 654.38+0 cents every day, then in this case, the national savings will be 6.5438+0.3 million yuan, and everyone will spend more than 6.5438+0.0 million yuan from primary school to university. According to this calculation, you can earn 654.38. If I had so much money, I would share it with the children!
It suddenly occurred to me that many hands make light work, but it also has disadvantages, right? Because if everyone wastes 65.438+0.3 billion more water every day, what a shame!
I did a small experiment: I dropped 1000 drops of water under the tap, weighing 200 grams, and I began to calculate:/kloc-0 130000000 divided by 1000 multiplied by 200 equals 26000000000 grams, and then 260000000 tons of water equals 260 years. I went to ask my parents, "1 ton of water can generate 100 kwh?" I thought about it and calculated that 260 tons of water can generate 26,000 kwh of electricity.
Whoa, whoa! I was shocked for five minutes. 260 tons of water can do so much! Therefore, from now on, all of us should save water and not waste a drop of water, and form a good habit of saving.
I believe that there is mathematics everywhere in life, and mathematics is used everywhere. As long as you are willing to learn mathematics, you can feel the happiness of mathematical thinking even in the game! ! !
4. Primary school math composition 500 words beautiful math
At noon today, in order to measure the size of chopsticks more accurately, I asked my father to take a slender measuring cylinder from the chemistry room. The scale unit is smaller, and each unit is only 1 cubic centimeter. At this point, I seem to feel victory beckoning to me. I really have everything except hands-on experiments.
First of all, I drew a dividing line on disposable chopsticks with a pencil, divided the chopsticks into two sections evenly, and soaked them in water to avoid washing them when measuring. Then, insert the chopsticks into the measuring cylinder, drop water into the measuring cylinder with a dropper, let the water in the measuring cylinder rise to the dividing line of the chopsticks, take the chopsticks out of the measuring cylinder after recording the water level scale (38 ml), and then record the water level scale (34.5 ml) in the measuring cylinder. The difference between the two water level gauges is the volume of this part of chopsticks, which is 3.5 cubic centimeters. In the same way, I measured the volume of the other part of the chopsticks to be 5 cubic centimeters. When the two measurements are added together, the volume of the chopsticks is 8.5 cubic centimeters. When I got the result, I cried excitedly. How proud and proud I am at this time!
Then, according to the situation that each person uses three pairs every day, I calculated the disposable chopsticks consumption of our school (1500 people) and the whole country (1200 million people) for one year, which are 13.96 cubic meters and169000 cubic meters respectively. The result surprised me. What a pity to waste so many wooden disposable chopsticks every year! I hereby appeal to the students at school, no! It is the people of the whole country, and it is not! Everyone in the world should stop using disposable chopsticks. Only in this way can we protect our forest resources, make our earth environment better and let everyone on the earth breathe clean and fresh air.
Change it yourself.
5. Mathematics papers in life. Mathematics with 500 to 800 words can be said to be everywhere in our life. When we pay for things in the supermarket, when we measure the area of a thing, when we make objects with various shapes such as parallelogram, right angle and triangle, we can directly use mathematical knowledge in our lives. A few days ago, something happened in our family to solve life problems with mathematical knowledge.
When I came home from school that day, I sat in a small chair and heard a "crunch", which scared me to jump. Ha, it turns out that one leg of the chair is loose. "How about we fix the chair?" I said to my parents on impulse. Mom and dad said "yes" with great support. So the whole family began to get busy, looking for tools, holding chairs and nailing. After the "scratching" sound, several big nails were nailed into the loose chair legs. "Hey, it's finally nailed." I clapped my hands and sat up with satisfaction. Crunch. Hey, what's up? What should I do? Suddenly, I remembered what the math teacher said: triangles can stabilize objects. Yeah, why didn't I think of that just now? I immediately found a small piece of wood, cut it into four small triangular pieces of wood with the same size according to the angle formed by the four legs of the small chair and the chair surface, and then filled the triangular pieces of wood in the gaps between the chair legs and the chair surface respectively, and nailed them firmly. Needless to say, this chair is safe to sit on.
Hey, these numbers are amazing. It seems that I must study mathematics harder in the future, apply mathematics to every bit of life, analyze and solve practical problems in life, and better adapt to the development and needs of society. Make life more meaningful.
6. Mathematics paper "Mathematics in Life" is urgent. Mathematics in the game 1000 words.
One day, Sister Xixi played a game for us: two people counted from 1 to 10 in turn, and only counted to 1, 2 or 3 at a time. Whoever reports 10 first wins.
Everyone wants to "knock down" each other, but how can they win 100%? This question has been echoing in my mind, which makes me puzzled.
After returning home, I picked ten stones in a small basket for a novice to operate. I called my father and asked him to play this game with me. I found a pen and a notebook and recorded every step I did. The rule is this: my father and I take turns to take stones, up to three, and at least 1. Whoever gets the last one wins.
I lost the first game. It turned out that my father took it first, and my father made me lose "miserably" in the shortest time; I won the second game first, and I really won. ...
I read the record several times, and finally found that I added up the largest and smallest numbers: 1+3=4, and divided the total number of stones by the sum of the largest and smallest numbers, which is 10 ÷ 4 = 2...2. If there is a remainder, I will take it first, and the remainder is only a few stones. If there is no remainder, I will take it first. Now that the remainder is 2, I will take 2 stones, and the sum of the remaining stones and the opponent is a divisor of 3, so I can win.
In order to ensure the accuracy of the answer, I took 28 stones and played with my father again. With the above rules, I am invincible! ! !
It turns out that mathematics is everywhere in life, and they are waiting for you to discover!
7. Is there a math composition in life? Our life is inseparable from mathematics, such as the weight of food, the date of a year on the calendar, and some mathematical equations are all related to mathematics. Today, I want to introduce some math problems to you!
When we wake up in the morning and open our hazy eyes, the first thing we see is the alarm clock. The numbers on the alarm clock are the mathematics in life. Because our time in a day is 24 revolutions of the hour hand, 0/440 revolutions of the minute hand/kloc and 86,400 revolutions of the second hand. Then 24*30= one month, one month * 12= one year, which is the mathematics of time.
The vegetable market we all want to go to is also inseparable from mathematics. On Sunday, my mother took me to buy food. In front of a booth selling cabbage, my mother bargained with the cabbage seller. Finally, I bought three catties of Chinese cabbage at a price of eighty cents a catty, and verbally agreed to buy three catties of Chinese cabbage. My mother asked me, "How much cheaper is it for me to buy food like this?" I thought about it and said to my mother, "It's twenty cents cheaper." If I have to sell vegetables, my aunt will praise me. When I got home, my mother asked me, "How did you calculate it?" I smiled and said, "Let me count 3 Jin of Chinese cabbage first *0. 8 yuan =2 yuan 4 jiao, then buy 3 kg to get 1 kg =4 kg, and then calculate 2 yuan 4 jiao ÷4 kg =6 jiao, then 8 jiao -6 jiao is not equal to 2 jiao! " This is the unit price * quantity = total price in life.
I usually go to Xinhua Bookstore with my mother by bus. The bus travels one kilometer per minute, and it takes about twenty minutes to get there. My mother asked me, "How many kilometers is our home from Xinhua Bookstore?" I gestured with my finger and said to my mother, "About twenty kilometers." This is the speed of life * time = distance.
"Diligence+Diligence = Success" is the truth I have realized through real life, and it is also the general order in which I solve problems. I always have to look at the questions first, master the relationship, list the formulas and answer them step by step. Sometimes, we have to draw pictures to understand the topic.
In fact, there are many wonderful mathematics in life, waiting for us to discover and discover.
8. Life and Mathematics Composition 500 Words Living in Happiness I live in a happy family and I have parents who make me happy.
Hard-working parents use their wise hands to build our happy home. They work hard and they get what they want. Although the family is not rich, they work and study happily every day.
When I was a child, I asked adults more than once: What is happiness? Some of them say they have money, others say they have power, and their parents say that happiness means a happy family living together. I think I must be happy.
Every day when I return to my warm home after school, a strong smell of food comes to my nose. Sometimes in the middle of homework, I can hear my mother shouting "eat" At this time, I am so happy.
My mother's cooking level is first-class. Every time my classmates and friends taste my mother's cooking, they say I'm "really happy". At that time, I was extremely proud. At the dinner table, I gulped down sweet and delicious food and praised my mother's skills. My mother always smiles with relief.
I think she must be very happy. I hate bad weather, not only because it brings a lot of inconvenience and disaster to people's lives, but also because my father works hard when the weather is bad.
That cold night, I was awakened by the sound of opening the door "Today, our home has electricity." My father excitedly told my mother how they electrified the last family. Listening to their gentle conversation, I climbed out of the warm bed and threw myself into my father's arms that I hadn't seen for days and nights.
My father's broad arms surround my mother and me, and my smile is full of joy and pride in overcoming the ice disaster. I think he must be very happy.
Sometimes, the family is chatting, and I like listening to their childhood stories best. Every time I see them blushing for the scandal of their childhood, I can't help laughing, and the consequence is that I am punished for cleaning up the "Dongdong" spewed out when laughing.
Sometimes, I will talk to them about my fantastic ideas, which are historical, geographical and biological ... When I published a "wonderful theory", my father mercilessly threw cold water on me and said "unrealistic", but I never gave up and even said "anything is possible", which caused my father to laugh innocently ... At this time, I was also happy. It is inevitable for a family to stumble, but they are always happy afterwards.
A child lives in fear, and he learns to worry; A child lives with irony, and he learns to feel inferior; A child lives with encouragement and learns to be confident; I live in happiness, and I think what I have learned will be to treat everything sincerely. In a colorful society with honest life, my childhood has long since left me, and I can't find any shadow of my childhood. There is nothing to be sad about, because I have entered another world.
One of them was unforgettable because it taught me the word "honesty". I left my childhood and the bungalow where I lived for ten years. I bought a building and opened a supermarket. Although business is not good, it can finally get by.
It was snowy winter when I first moved here, but a mahjong hall nearby was brightly lit every night. The boss there frequented, and later asked for my home phone number, saying that they would deliver the goods when they were busy.
One night, it was past eight o'clock in the evening when the phone suddenly rang. It was the boss who called his mother to deliver some goods. At this time, it was snowing heavily outside, and the supermarket was closed, but her mother promised to deliver them. Simply cleaned up, my mother went out with the goods, leaving me alone at home.
It was dark except for the faint light from my desk lamp. At that moment, I felt that time passed slowly.
A few minutes later, my mother came back, flushed as Santa Claus. But my mother didn't take off her coat, but took out a box of cigarettes from her pocket and changed it from the shelf. I haven't had time to ask.
She went out again. I went to the window and looked at the falling snow outside. I shudder at the thought that my mother finally came back, which seems to take more time than the last time. After my mother came back, I immediately asked her, "Mom, what did you do just now?" Mother replied, "Someone changed cigarettes."
But I saw that my mother still didn't mean to rest, so I asked her, "Are you still going?" My mother didn't answer me. I asked again before my mother replied, "They still need to change. I have to send it. " I said, "This is not a coin toss, just don't send it!" " Mother said, "how can this be done?" Besides, we have promised them.
How can you break your word? Besides, people are still waiting! This is a question of integrity! "Say that finish mother went away. Time passed by, and my mother finally came back. I saw her sitting on the bed silently without saying a word ... "Honesty is a symbol of strength, which shows a person's high self-esteem and inner sense of security and dignity. "
Living in the years, time is a changing song, time is a vicissitudes book, time is a tortuous river, and time is a bumpy road. Time flies, swallows go and come again; Willow withered and blossomed again.
But time flies, and the time we have is only the short light of a meteor across the dark sky. Facing it, I am at a loss. I live in the years, but I have no pity for it.
The years are changeable, from slavery to democracy, from barbarism to civilization, from war to stability, from backwardness to advanced. These changes are immersed in the years, and history shows us the years. I live in the years and marvel at the miracle of change. Years are gray, and how long it takes is just a meteor. The ancient working people left us vicissitudes and brilliant achievements, engraved in the footprints of years.
I live in years, and years reproduce history. Time flies, looking back on the road, confused, as far away as a mirage. This may be my hesitation, this may be my choice.
I live in the years, and the years are like hemp, but I insist on myself. Time is the most easily lost, like a forest, lush but blurred, like a desert, flat but boundless.
Strengthen yourself, be clear about yourself, believe in yourself, be clear about the course of life, turn into a boat, fight the wind and waves, and sail to the goal without showing weakness. I'm not the only one living in the years. The clouds dispersed gently, the wind gradually stopped, and the years left some crow's feet.
9. Mathematics in Life (800-word paper) Original Publisher: China Academic Journal Network.
Mathematics in life: Mathematics in life should be applied in real life. Mathematics is used by people to solve practical problems. In fact, there will be math problems in life. For example, it is natural to add and subtract when shopping on the street, and to draw pictures naturally when building a house, and divide apples and pancakes. There are countless such problems. This knowledge comes from life and is finally summed up as mathematical knowledge to solve more practical problems. We should learn mathematics in life and use it in life. Mathematics is inseparable from life. The new curriculum "Standard" advocates everyone to learn valuable mathematics, which is actually closely related to students' real life and past knowledge and experience. It is mathematics that students use to solve some practical problems in life, that is, mathematics in life. How to make everyone learn valuable mathematics, that is, learn mathematics in life, let me talk about my experience. First, discover, master and use mathematics from students' familiar life background, for example, when teaching the addition of hundreds of thousands of numbers. Before class, I recorded and played the most familiar shopping scene of "Zhong Bai Warehouse". When the students saw this scene, they were all very excited, because "Zhong Bai Warehouse" is a familiar shopping place, and the students felt particularly cordial. Then, introduce the students into the household appliances area of Zhong Bai warehouse, observe the prices of these household appliances, and let the students freely ask mathematical questions calculated by addition. The students were very involved and spoke enthusiastically. Second, let students learn valuable mathematics in operation because primary school students' life experience and understanding of things are relatively lacking. Let students personally experience and feel the mathematics in life in operation, leaving a deep impression in their hearts, learning deeply and remembering firmly. For example, when teaching the problem of painting walls, I led the students to measure the length and height of the walls themselves, which not only consolidated the relevant
10. How does math diary write about life in life?
Huan Qingxin, Class 3, Grade 5
One day, I was reading a book about math problems.
Suddenly, a question stumped me. The problem is this: there are three switches downstairs and a light upstairs, but only one of the three switches can turn on the light upstairs. You only have one chance to go upstairs, and you can only turn on one switch at a time. How do you know which switch controls the light upstairs? The problem is that there is only one chance to go upstairs. According to the common problem-solving ideas, open one, go upstairs to see if it is bright, and go downstairs. There are two switches left. Which one to choose? What should I do according to the method of Olympic numbers?
I can't think about it. Beat. Look at the answer at the back of the book, uh-oh! I see! It's that simple! The solution is this: turn on the first switch for one minute, then turn on the other switch and go upstairs to check. If it is on, there is no doubt that it is the second switch. If it is not on, feel whether the lamp is hot, because if the first switch is connected to the lamp and heated for one minute, the first switch will be hot. Not spicy, excluding the first and second, it is the third! Math problem solved! This question tells me that math problems are not only solved by laws, but life is actually the best helper!
I wrote this, too. I think it's ok. I'll make a copy for you. Hope useful to you
