1, interesting math story-how many peaches did Bajie eat?

Bajie went to Huaguoshan to find Wukong, but the Great Sage was not at home. The little monkeys warmly entertained Bajie and picked 100 of the most delicious peaches in the mountains. Bajie said happily, "Let's eat together!" How to eat? Counting ***30 monkeys, Bajie found a branch and drew it on the ground, and listed the formula, 100 ÷ 30 = 3... 1.

Pig Bajie pointed to the top three and said generously, "You can eat three peaches each. Look, the rest 1 I ate it! " The little monkeys were very grateful to Bajie. They thanked him one by one, and then each took his share.

When Wukong came back, the little monkeys told Wukong how generous Bajie was today and why he only ate a pecan. Wukong saw Pig's arrangement and shouted, "What a fool! I'll find him! "

Haha, do you know how many peaches Bajie ate?

2. The content of interesting mathematical stories-the origin of Arabic numerals

Xiaoming is a child who likes to ask questions. One day, he became interested in the numbers 0-9: Why is it called "Arabic numerals"? So he went to ask his mother, "Since 0-9 is called Arabic numerals, it must have been invented by Arabs, mom?"

Mom shook her head and said, "Arabic numerals were actually invented by Indians." About 1500 years ago, Indians used a special word to represent numbers. There are 10 words, and you can write both strokes. Later, these figures were introduced into Arabia. Arabs think these numbers are simple and practical, so they are widely used in their own countries and spread to Europe. In this way, it gradually became the number we use today. Because Arabs have played a very important role in spreading these numbers, people are used to calling them "Arabic numbers". "

Xiao Ming heard this and said, "So that's it. Mom, can this be called' making a mistake'? " Mom smiled.

3. Interesting mathematical story content-children's song contest

The animal school held a children's song competition, with the elephant teacher as the referee.

The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten. Add ten and one to count quickly and accurately. "

As soon as the little monkey finished speaking, the puppy began to recite again: "abdication and subtraction are not difficult, just align the numbers." If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing. How to reduce ten digits, ten digits will be reduced again and again. "

Everyone applauded their wonderful performance. Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them.

4, interesting math story-and = skills

A long time ago, the kingdom of mathematics was chaotic. The 0-9 brothers not only dominate the kingdom, but also boast of their greatest skills. The math angel was very angry when he saw this situation. He sent three little angels to the math kingdom to establish order and avoid chaos.

Three little angels came to the kingdom of mathematics, and 0-9 brothers looked at them contemptuously. Q: "What are you three doing in the kingdom of mathematics? You are not welcome! "

= Laugh and say, "We are judges sent by angels to help you govern your country. I am an equal sign, and these two are' greater than sign' and' less than sign'. Whoever they speak to is greater. Whoever they point to is small. "

When the ten brothers heard that they were judges sent by angels, they obeyed the order of sum = obediently. Since then, the mathematical kingdom has a strict order, and no one will violate it.

5. Interesting math story-Little Bear opens a shop

Bear doesn't like studying, but just wants to do business, so he opened a fruit shop next to the school. Rabbit and monkey are his classmates. They have agreed to teach this lazy guy who doesn't like school.

They came to bear's fruit shop.

"How much are the peaches?" Asked the little monkey.

"The first basket is 6 yuan and 3 Jin, and the second basket is 6 yuan and 2 Jin." The bear replied.

The little monkey said, "If I take 5 kilograms from two baskets, I will pay you 12 yuan, right?"

The bear nodded.

"That I want it all. Since 5 kg is 12 yuan, then 60 kg is 12× 12= 144 yuan, right? "

"Exactly, exactly." Said the bear.

So the little monkey bought all the peaches, paid the money and left happily with the little rabbit.

When I get home at night, the bear pays the bill, which is a loss anyway. The next day, the little monkey and the little rabbit found the little bear and told him the situation. They smiled and said, "It's all because you didn't study hard, so we'll teach you a lesson" and replenished the little money to the bear.

Bear hung his head in shame, and since then, he has been very serious in class every day. The three of them became good friends.

6. Interesting math story-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. Soon, the three disciples came back 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. We all chose the same quantity. There are less than 65,438+000 peaches in my basket. If you count three, 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?

Tang Priest quickly told the number of peaches each of them picked. Do you know how many peaches they each picked?

7. Interesting mathematical story content-clever little boy

Once upon a time, a king often gave his ministers around him difficult questions for fun. If ministers do something right, he will give them a little reward with a little kindness. If you can't answer, you will be punished or even beheaded.

One day, the king pointed to a pond in the palace and asked, "I will give jewels to anyone who can tell how many buckets of water there are in the pond." If you can't say it, I will' reward' each of you with 50 whips. "Ministers were stumped by this sudden question.

Just as the ministers were in confusion, a little boy came over to herd cattle. He asked the reason and said, "I want to meet this king."

The ministers brought the little boy before the king. Seeing the little boy in front of him was black, thin and small, the king said doubtfully, "If you can't answer this question, you will be beheaded, you know?" Everyone present made a sweat for the little boy, but the little boy answered the king's question unhurriedly. In desperation, the king gave the little boy a gem award. Children, do you know what he answered?

In fact, the king is a problem of insufficient conditions. It is impossible to find the right answer in normal thinking mode. The little boy just caught the key. He replied like this: "it depends on the size of the bucket: if the bucket is as big as the pond, it is a bucket of water;" If the bucket is only half the size of the pond, there are two buckets of water; If the bucket is one-third the size of the pond, that's three buckets of water ... "

The little boy actually broke the habitual thinking mode, and the specific problems were analyzed. How clever and flexible his mind is!

8. Interesting mathematical story: a mathematician triggered by a story.

Chen Jingrun is a famous mathematician, who has made great contributions to overcoming Goldbach's conjecture and founded the famous "Chen Theorem", so many people affectionately call him "the prince of mathematics". But who would have thought that his achievement originated from a story?

From 65438 to 0937, diligent Chen Jingrun was admitted to Huaying College in Fuzhou. One day, Teacher Shen Yuan told us a story in math class: "A Frenchman discovered an interesting phenomenon 200 years ago: 6=3+3, 8=5+3, 10=5+5, 12=5+7, 28=5+23. Every even number greater than 4 can be expressed as the sum of two odd numbers. Because this conclusion has not been proved, it is still a guess. Euler said: Although I can't prove it, I am sure this conclusion is correct.

From then on, Chen Jingrun became interested in this wonderful question. In his spare time, he likes going to the library. He not only read the counseling books in middle schools, but also eagerly read the textbooks of mathematics and physics courses in these universities.
