2. The story of the fifth-grade math master is 400 words.

Hua

Once, he went out to play with his neighbor's children, and they walked; Suddenly I saw an abandoned grave by the roadside, and there were many stone men and horses beside the grave. This immediately aroused Hua's curiosity, and he really wanted to find out. So he said to the neighbor's children:

"There may be some interesting things. Shall we go and see? "

The neighbor's child replied, "ok, but only for a while." I'm a little scared. "

Bold Hua said with a smile, "Don't be afraid, there are no ghosts in the world." With that, he ran to the grave first.

The two children studied the stone man and the horse carefully before they came to the grave. They groped around and found it interesting. Thinking Hua suddenly asked the neighbor's children, "How heavy are these stone men and horses?"

The neighbor's child looked at him puzzled and said, "How should I know? How can you ask such a stupid question? No wonder people call you' Luo Idiot'. "

Hua said disappointedly, "Can you think of a way to calculate?"

The children in the neighborhood laughed and said, "Wait till you become a mathematician in the future!" ! But if you can become a mathematician, I'm afraid you will work at sunrise and rest at sunset. "

Despite the ridicule of the children next door, Hua firmly said, "I will definitely find a way in the future."

Of course, calculating the weight of these stone men and horses is not a problem for Hua, who later became a mathematician.

3. The fifth grade math story

1, children of gauss series, do you know the story of gauss, a mathematical genius, when he was a child? When Gauss was in the second grade of primary school, once the teacher wanted to have a rest after teaching addition, so he asked the students to do some calculations. The topic is:1+2+3+4 ...+96+97+98+99+100 =? I thought the students would be quiet for a while, but I was about to find an excuse to go out, but Gauss stopped me! It turns out that Gauss has worked it out. Little friend, do you know how he did it? Gauss told everyone how he worked it out: add 1 to 100 and 100 to1; Line up in two rows and want to add, that is:1+2+3+4+………………+96+97+98+99+100+99+98+97+96+……+4+3+. 1+10 1+1* * has one hundred101,but the formula is repeated twice, so it is 65438+. Since then, the learning process of Gauss Elementary School has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius.

2, chickens and rabbits in the same cage Have you ever heard of the problem of "chickens and rabbits in the same cage"? This question is one of the famous and interesting questions in ancient China. About 1500 years ago, this interesting question was recorded in Sun Tzu's calculation. The book describes it like this: "There are chickens and rabbits in the same cage today, with 35 heads on the top and 94 feet on the bottom. The geometry of chicken and rabbit? These four sentences mean: there are several chickens and rabbits in a cage, counting from the top, there are 35 heads; It's 94 feet from the bottom. How many chickens and rabbits are there in each cage? Can you answer this question? Do you want to know how to answer this question in Sunzi Suanjing? The answer is this: If you cut off the feet of every chicken and rabbit in half, then every chicken will become a "one-horned chicken" and every rabbit will become a "two-legged rabbit". In this way, the total number of feet of (1) chickens and rabbits changed from 94 to 47. (2) If there is a rabbit in the cage, the total number of feet is more than the total number of heads 1. So the difference between the total number of feet 47 and the total number of heads 35 is the number of rabbits, that is, 47-35 = 12 (only). Obviously, the number of chickens is 35- 12 = 23. This idea is novel and strange, and its "foot-cutting method" has also amazed mathematicians at home and abroad. This way of thinking is called reduction. Reduction method means that when solving a problem, we do not directly analyze the problem first, but deform and transform the conditions or problems in the problem until it is finally classified as a solved problem.

3. Excellent math story: The door opened and a young man came in. Mr Liu Jianming asked him to sit down. The young man introduced himself and said, "I am a tour guide from the mainland." My name is yujiang county. I'm taking a tour group to Hong Kong this time. I heard that your hotel has a comfortable environment and good service. We want to stay in your hotel. " Mr Liu Jianming immediately said enthusiastically, "Welcome, welcome, welcome. I wonder how many people are there in your group? " "People, not bad, are a big group." Liu Jianming was overjoyed: It's great to have a big group and another big enterprise. As a tour guide, Yu Jiang saw Mr. Liu Jianming's mind. He remembered and said slowly, "Sir, if you can count the number of people in our group, we will stay in your hotel." "Please go ahead." Mr Liu Jianming said confidently. "If I divide my group into four groups on average, there will be one more person, and then divide each group into four groups on average, there will be one more person, and then divide the four groups into four groups on average, there will be one more person, including me, of course. How many people are there at least? " "How much is a * *?" Mr Liu Jianming immediately thought of this. He must take this business. "Without specific figures, how should we start?" He was a shrewd businessman and soon learned the answer: "At least 85 people?" Mr. Yu Jiang said happily, "Exactly, it's eighty-five. Please tell me how you worked it out? " "The least number of cases, is the last quartile, each is a person. It can be inferred that there are 1×4+ 1=5 (people) before the third score, and 5×4+ 1=2 1 (people) before the second score and the first score. " How many men and women do you have? ""There are 55 men and 30 women. " "We only have rooms for 1 1, rooms for 7 people and 5 people. How do you want to live? " "Of course, Sir, you have arranged, but men and women must be separated, and there can be no empty beds. "There will be a problem. Liu Jianming had never met such a guest, so he had to spend some time again. After thinking hard, he finally came up with the best plan: 1 1 two people, seven people in four rooms, five people in one room; One female room 1 1 person, seven people in two rooms, five people in one room, and one room * * *1/. After seeing his arrangement, Mr. Yu Jiang was very satisfied and immediately went through the accommodation formalities. Made a big deal. Although it is a bit complicated, Mr. Liu Jianming is still very happy in his heart.

4. Seven mathematical stories in life, no less than 400 words,

This afternoon, my mother and I went shopping in the supermarket.

When we finished buying what we needed, we were about to leave. I saw sausages on the shelf, so I asked my mother to buy some sausages, and my mother agreed. But just after a few steps, I saw a package with the same brand and weight on the shelf, which contained 10 pieces at 4.30 yuan each. Do you want to buy a pack or a slice? I hesitated. Suddenly, my mind turned and I understood. Just compare and see which one is cost-effective. So I started to calculate: if I buy 10 pieces in retail, each piece costs 40 cents, which is equal to 4 yuan, and the whole package costs 4.30 yuan, which is 3 cents more, so I decided to buy it in bulk. I told my mother the process of my calculation, and my mother praised me for my love of brains. Also, I saw a puzzling math problem tonight. The topic is: 37 students want to cross the river. There is an empty boat at the ferry that can only take five people. How many times must they cross the river with this boat at least?

Careless people often ignore the "empty boat", that is, forget to have a gondola, so they can only take four people at a time. In this way, 37 people subtract one rowing classmate, leaving 36 students, 36 divided by 4 equals 9, and the classmate who worked as a boatman on the other side for the last time also landed 4, so it takes at least 9 trips.

5. A little math story of 400 to 500 words.

The story of mathematician gauss when he was a child

From one to one hundred

Gauss has many interesting stories, and the first-hand information of these stories often comes from Gauss himself, because he always likes to talk about his childhood in his later years. We may doubt the truth of these stories, but many people have confirmed what he said.

Gauss's father works as a foreman in a tile factory. He always pays his workers every Saturday. When Gauss was three years old in the summer, when he was about to get paid, Little Gauss stood up and said, "Dad, you are mistaken." Then he said another number. It turned out that three-year-old Gauss was lying on the floor, secretly following his father to calculate who to pay. The results of recalculation proved that little Gauss was right, which made the adults standing there dumbfounded.

Gauss often joked that he had learned to calculate before he learned to speak, and often said that he learned to read by himself only after consulting adults about the pronunciation of letters.

At the age of seven, Goss entered St. Catherine's Primary School. When I was about ten years old, my teacher had a difficult problem in arithmetic class: "Write down the integers from 1 to 100 and add them up! Whenever there is an exam, they have this habit: the first person who finishes it puts the slate face down on the teacher's desk, and the second person puts the slate on the first slate, thus falling one by one. Of course, this question is not difficult for people who have studied arithmetic progression, but these children are just beginning to learn arithmetic! The teacher thinks he can have a rest. But he was wrong, because in less than a few seconds, Gauss had put the slate on the lecture table and said, "Here's the answer! Other students added up the numbers one by one, sweating on their foreheads, but Gauss sat quietly, ignoring the contemptuous and suspicious eyes cast by the teacher. After the exam, the teacher checked the slate one by one. Most of them were wrong, so the students were whipped. Finally, Gauss's slate was turned over and there was only one number on it: 5050 (needless to say, this is the correct answer. The teacher was taken aback, and Gauss explained how he found the answer:1+100 =1,2+99 =10/,3+98 =/kloc-. A * * * has 50 pairs, and the sum is 10 1, so the answer is 50 × 10 1 = 5050. It can be seen that Gauss found the symmetry of arithmetic progression, and then put the numbers together in pairs, just like the general arithmetic progression summation process.

6. The fifth grade math story, about 300-400 words. It's better to be anxious. Answer in 20 minutes.

Newton: Do everything silently with your heart.

Newton liked reading since he was a child, and he was very diligent. He especially likes making by hand. He spent all his pocket money on woodworking tools. He made many exquisite windmills, kites, sundials, clepsydra and other practical instruments. Newton did not show his extraordinary talent when he was young. The difference is that the hands-on ability is quite strong. Every time he does something, he always keeps silent and works hard. If you don't do well, tear it down and redo it. Never be careless. Newton was very diligent and couldn't catch up with others in his academic performance, especially since he spent most of his life in the laboratory. He often works in the laboratory all night, sometimes for six weeks, day and night, until he finishes the experiment. Although Newton was a great scientist, he was never complacent. He said modestly: on the road of science, we are just children playing by the sea and accidentally picked up a beautiful stone. As for the sea of truth, I haven't found it yet!

Newton was so modest and tireless in studying knowledge!

7. Math Story Grade Five (Less)

The spider's "gossip" net is a complex and beautiful octagonal geometric pattern, and it is difficult for people to draw a symmetrical pattern similar to a spider's net even with the compass of a ruler.

In winter, when a cat sleeps, it always hugs its body into a ball. There is also mathematics in it, because the shape of the ball minimizes the surface area of the body, so it emits the least heat.

The real "genius" of mathematics is coral. Coral writes a "calendar" on its body, and "draws" 365 stripes on its wall every year, apparently one a day. Strangely, paleontologists found that corals 350 million years ago "painted" 400 watercolors every year. Astronomers tell us that at that time, the earth only had 2 1.9 hours a day, not 365 days a year, but 400 days.

10, Tang Priest and his disciples picked peaches.

One day, the Tang Priest told his disciples Wukong, Bajie and Friar Sand to go to Huaguoshan to pick peaches. Before long, the three disciples returned happily after picking peaches. Tang Priest and his disciples asked: How many peaches did each of you pick? Bajie said with a silly smile, Master, let me test you. Each of us took the same amount of money. There are less than 65,438+000 peaches in my basket. If we count three peaches, there are 1 peach left in the end. Do the math. How many did each of us choose?

Friar Sand said mysteriously, Master, I will test you, too. If there are four peaches in my basket, there is 1 left in the end. Do the math. How many did each of us choose?

Wukong smiled and said, Master, I'll test you, too. If there are five peaches in my basket, there will be 1 in the end. Do the math. How many shall we each choose?

Skills 1 1, ">", "

A long time ago, the kingdom of mathematics was in chaos and disorder. The ten brothers from 0 to 9 not only dominate the kingdom, but also boast about their best skills. Digital angel was very angry when he saw this situation, so he sent three little angels, ">", "

The angel smiled and said, "We are the judges sent by the angel to help you manage your country well. I am an equal sign. The numbers on both sides of me are always equal. These two are' greater than number' and' less than number'. Who they open their mouths to is big, and who they point at is small. On hearing that the judges were sent by digital angels, and with the introduction of "=", 0~9 brothers obediently obeyed the order of ">".

12 and the story of "0"

Roman numerals are symbols representing numbers, which are combined to represent different numbers according to certain rules. When using this number, the number "0" is not needed. At that time, a scholar of the Roman Empire discovered the symbol "0" from Indian notation. He found it very convenient to use "0" for mathematical operations, and he also introduced the Indian method of using "0" to everyone. The Pope knew then. The Pope was very angry. He rebuked that the sacred number was created by God, and there was no "0" monster in the number created by God. So he ordered the scholar to be arrested, and his ten fingers were tightly clamped with a clamp, so that his hand was disabled and he could no longer write with a pen. In this way, "0" was banned by the ignorant and cruel Pope. However, although the use of "0" is forbidden, Roman mathematicians still use "0" secretly in mathematical research regardless of the ban, and still make a lot of mathematical contributions with "0". Later, "0" was finally widely used in Europe, but Roman numerals were gradually eliminated.

13, the oldest and most interesting math problem

In seven houses, each house has seven cats; No matter which of the seven cats can catch seven mice; Each of these seven mice eats Three wheat; If each ear of wheat can peel off seven grains of wheat, how many houses, cats, mice, ears of wheat and grains of wheat add up?

A: The total number is 19607.

There are 7 rooms in the house, with 7x7 = 49 cats, 7X7X7=343 mice, 7x7x7 = 240 1 ear wheat and 7x7 = 16807 grains of wheat. All add up to 7+72+73+74+75 = 19607.

14, cell conjecture

Honeycomb is a very sophisticated construction project. When bees build nests, young and middle-aged worker bees are responsible for secreting flaky fresh beeswax, each of which is only the size of a needle, while other worker bees are responsible for carefully placing these beeswax in a certain position to form a vertical hexagonal column. The thickness and error of each beeswax partition wall are very small. The width of the six partition walls is exactly the same, and the included angle between walls is exactly 120 degrees, forming a perfect geometric figure. People have always wondered why bees don't make their nests into triangles, squares or other shapes. Why is the partition flat, not curved? Although the beehive is a three-dimensional building, each beehive is a hexagonal cylinder, and the total area of beeswax wall is only related to the cross section of the beehive. This leads to a mathematical problem, that is, to find the plane figure with the largest area and the smallest perimeter.

15, snails climb well

German mathematician Reese once wrote a math problem: the well is 20 feet deep and the snail is at the bottom of the well. It climbs 7 feet during the day and drops 2 feet at night. How many days will it take to reach the wellhead?

Analysis: If you think the answer is 20/(7-2)=4, it's all wet! The key to solve this problem is to consider that the crawling situation on the last day is different from that of the previous days.

Solution: The height of snail crawling day and night in the first 3 days:

(7-2)×3= 15 (feet) Last crawling time: * * Time spent:

16 Measure the height of the pyramid.

One day, Thales saw people reading the notice, so he went up to read it. The initial notice said that Pharaoh wanted the smartest person in the world to measure the height of the pyramid. Thales is going to Pharaoh. Pharaoh asked Thales what tools he used to measure the pyramids. Thales said that it is strange that everyone only uses a stick and a ruler. He put the stick next to the pyramid, and when the shadow of the stick was as long as the stick, he measured the pyramid. He measured the length of the shadow of the pyramid and half the length of the bottom of the pyramid. Add these two lengths to get the height of the pyramid. Thales is really the smartest man in the world. He can easily measure the height of the pyramid without climbing to the top.

About 1500 years ago, European mathematicians did not know how to use "0". They use Roman numerals. Roman numerals are symbols representing numbers, which are combined to represent different numbers according to certain rules. When using this number, the number "0" is not needed. At that time, a scholar of the Roman Empire discovered the symbol "0" from Indian notation. He found it very convenient to use "0" for mathematical operation, and he was very happy. He also introduced the Indian method of "0" to everyone. After a while, it was known by the pope at that time. At that time, it was the Middle Ages in Europe. The power of the church was very strong, and the power of the pope far exceeded that of the emperor. The Pope was very angry. He rebuked that the sacred number was created by God, and there was no such monster as "0" in the number created by God. Anyone who wants to introduce now is blasphemous! So the Pope ordered the scholar to be arrested and tortured, and his ten fingers were tightly clamped with a clamp, so that his hand was disabled and he could no longer write with a pen. In this way, "0" was banned by the ignorant and cruel Pope. However, although the use of "0" is forbidden, Roman mathematicians still use "0" secretly in mathematical research regardless of the ban, and still make a lot of mathematical contributions with "0". Later, "0" was finally widely used in Europe, but Roman numerals were gradually eliminated. The following is a short story, a story between numbers. One day, when the digital cards were having lunch together, the youngest one spoke. Brother 0 said, "Let's take some photos together. What do you think? " 0' s brothers and sisters said in unison, "Good." Brother 8 said, "Brother 0' s idea is really good. I will be a good person once. Shall I provide camera and film for Brother 8? " Old four said, "starling, yes, it's just a little troublesome." Better use my digital camera. That's settled. "So, they got busy. Finally, they helped them shoot, and immediately sent the digital camera to the print shop. The computer sister tried to ask them for money, but who paid for it? They stared at each other one after another. This is what the computer sister said, "A ***5 yuan, a * * * eleven brothers and sisters, how much does a person pay on average? "Among the eleven of them, Liu is the cleverest, and this time it is the first to work out the result. Do you know how it is worked out? When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to have a rest, he came up with a topic for students to calculate. The topic is:1+2+3+...+97+98+99+100 =? The teacher is thinking, now the children must start class! I used this as an excuse to go out, but Gauss stopped me! ! It turns out that Gauss has worked it out. Little friend, do you know how he did it? Gauss told us how he worked it out: add 1 to 100, add 100 to 1, and add them to two lines, namely1+2+3+4+...+96+97.

Does it suit you? Thank you.

8. Grade five math diary has more than 400 words.

Math diary

This morning, I was worried about what math diary wrote. Wandering around the internet, hoping to meet some inspiration. Suddenly, an article in the newspaper attracted me:

"Eight-way experimental primary school six (7) class Xu Ruixiang.

I saw such a problem in the "two-color class for primary school students" this afternoon.

The bottom radius of the cone is 8 decimeters, and the ratio of height to bottom radius is 3: 2. What is the volume of this cone?

Analysis: This is a proportional application problem ... "

I figured it out on this issue without reading the analysis, huh? I haven't learned how to calculate the area of a cone. Then how can I solve this problem? I sighed, ready to continue to watch the analysis, and then I thought, will I be in the sixth grade soon after this summer vacation? If you can't even do the questions in this course. What kind of Olympics class am I? Is it not worthy of the name? Yes, I have to solve it myself.

As usual, I must build a model in my mind before this kind of problem, but I am very cautious about this problem for fear of making mistakes. I drew a perspective effect of a cone on the paper. Take a closer look, huh? Isn't this figure the same as a triangle if it is a plane figure? Isn't the cubic area of this cone 1 of the area of a cylinder with the same base and height? I am ecstatic. The original cone area is also easy to find. As long as you know the height and bottom area of the cone, can't you get it? Back to this question, its condition tells you the radius of the bottom, which is equivalent to telling the area of the bottom. It says that the ratio of height to bottom radius is 3: 2, which means that the length of bottom radius is two-thirds of height. Isn't that height just radius ×3÷2= height? Therefore, the height is 12 decimeter, the bottom area is 200.96 cubic decimeter, and the cone area is 200.96×12 ÷ 2 =1205.76 cubic decimeter.

"Wow, I finally solved it." I heaved a sigh of relief. Through this question, I also found that there are many things in mathematics, just like the area of a cone and the area of a triangle. In fact, you don't need to know all the calculation formulas, as long as you can understand them, you can also solve problems.

9. Mathematicians' short stories are 400 words.

When Hua was in primary school, when a teacher introduced the school to a new teacher, he said that the students in this school were all poor children and most of them were idiots ... This deeply hurt Hua's heart and he was determined to repay the teacher with excellent results.

One day, the math teacher gave us an interesting question: "I don't know how many things there are." Two of the three plots remain, three of the five plots remain, and two of the seven plots remain. How many things are there? "

The whole class looked at each other, unable to answer. Only Hua stood up and said, "Teacher, I know it is' 23'." The whole class was shocked and the teacher nodded in praise. From then on, he fell in love with math class.

When he was studying, his father's shop business was getting worse and worse, so he had to drop out of school to look at the counter. He began to teach himself, using an algebra book, a geometry book and a calculus book, with only 50 pages left. I don't have time during the day, and I keep a small oil lamp to calculate repeatedly at night. His father called him a "bookworm" and forced him to burn books several times, but his neighbors advised him to do business well.

Unfortunately, he suffered from terrible typhoid fever again, and the doctor shook his head and sighed, asking his family to prepare a "funeral" for him. He challenged death, struggled to work in the field, and his left leg was disabled. Undaunted, he exercised with crutches and endured pain. Having practiced enough, he went to a middle school to fetch water and sharpen pencils for the teacher. Even so, he didn't give up self-study.

Soon after working in middle school, he began to send mathematical papers to newspapers and magazines, and he never gave up after being rejected many times. Later, he published the article "Why can't the solution of Su Jiaju's algebraic quintic equation be established?", which was appreciated by Xiong Qinglai, a master of mathematics, and was soon introduced to Tsinghua campus.

(9) Extended reading of 400-word fifth-grade math stories in life.

The growth process of China

19101012 was born in Jintan District, Changzhou City, Jiangsu Province. When he was young, he liked to think. Because he was too absorbed in thinking, he was often nicknamed "Luo bookworm" by his companions. 1922, 12 years old, after graduating from Renmai Primary School in the county, entered Jintan County Junior High School. Teacher Wang Weike discovered his mathematical talent and tried his best to cultivate it.

1925, studied in Shanghai China Vocational School after graduating from junior high school. I dropped out of school because I couldn't afford the tuition and went home to help my father manage the grocery store, so I only had a junior high school diploma all my life. Since then, he has taught himself all the math courses in high school and junior college in five years.

/kloc-in the autumn of 0/927, he married Wu. /kloc-in the winter of 0/929, he was unfortunately infected with typhoid fever, leaving his left leg disabled for life. He had to walk on crutches. From 65438 to 0929, Hua was employed as a clerk in Jintan Middle School and began to publish papers in Shanghai Science and other magazines.

1in the spring of 930, Hua published "Why the solution of Su Jiaju's algebraic quintic equation can't be established" in Shanghai Science magazine, which caused a sensation in the mathematical field. In the same year, Xiong Qinglai, the head of the Department of Mathematics in Tsinghua University, broke away from convention after learning about Hua's self-study experience and mathematical talent, and asked Hua to work as a librarian in Tsinghua University Library.

193 1 year, teaching assistant, Department of Mathematics, Tsinghua University. He taught himself English, French, German and Japanese, and published three papers in foreign magazines. 1933, promoted to teaching assistant. /kloc-0 was promoted as a lecturer in September, 934.
