Make a bouquet with 96 red flowers and 72 white flowers. If the number of red flowers in each bouquet is the same, then the number of white flowers is the same, and there are at least a few flowers in each bouquet.

2. What are the short stories about mathematics in the fifth grade of primary school? I'm doing my homework, don't copy it.

One day, when the digital cards were having lunch together, the youngest one spoke.

Brother 0 said, "Let's take some photos together, boys from our university. 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 4 said, "Brother 8, it's good, but it's a little too much trouble. Better use my digital camera. That's settled. "

So, they got busy. Finally, they took pictures for them 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 one person pay on average?"

Among the eleven of them, Lao Liu is the cleverest, and this time he is the first to work out the result. Do you know how it is worked out?

Today, my family went to KFC in Longgang for a family meal.

When we get there, people are always crowded. We finally ordered good food and found a seat to sit down. Here comes the food. This is a sumptuous set meal. There are 12 drumsticks in it. I thought: how to divide it equally? Then I remembered the division of 12÷3=4. We each have four drumsticks. Later, I ate my mother's 1 chicken leg and my aunt's two chicken legs. My aunt said, "You can't eat this for free. I ask you, how much did you eat? " How many more servings do you have to eat before you can finish them all? "I thought about it and replied," I ate 7/ 12, and then I ate 5/ 12. I ate all of it. "Fortunately, I learned the knowledge of fractions and can answer the questions correctly.

Today, my mother gave me 10 yuan to go shopping in the supermarket. I bought a string of firecrackers 2/ 10, four lollipops/10, seven balloons 2/ 10, and finally a comb 4/ 10, a *. There is still one yuan left, and I have to pay it back to my mother. (3) At night, I saw a difficult problem in the Olympiad Book: the number of apple trees in the orchard is three times that of pear trees. Master Lao Wang fertilizes 50 apple trees and 20 pear trees every day. A few days later, all the pear trees were fertilized, but the remaining 80 apple trees were not fertilized. Excuse me: How many apple trees and pear trees are there in the orchard?

I am not intimidated by this question, but it can stimulate my interest. I think the apple tree is three times as big as the pear tree. If two kinds of trees are to be fertilized on the same day, Master Lao Wang will fertilize "20×3" apple trees and 20 pear trees every day. In fact, he only fertilizes 50 apple trees every day, which is 10, and the last 80 trees. Therefore, Master Lao Wang has been fertilizing for 8 days. 20 pear trees a day, 8 days is 160 pear trees. According to the first condition, there are 480 apple trees. This is to solve the problem with the idea of hypothesis, so I think the hypothesis method is really a good way to solve the problem.

There is a problem in today's math homework to weigh a pair of shoes. So I went to my mother and asked for a scale. Mom said she didn't have weighing scale. What shall we do? However, as the saying goes, "Nothing is difficult in the world". I think there must be a way.

So, I used my clever brain and came up with a homemade balance.

I cut off the paper covers of the empty moon cake box piece by piece, brought transparent folding tape, folded one of the paper covers into a regular triangle and put it on the table. Another piece of paper is made into the left and right disks of the balance and placed on the triangle in a balanced way. Then find something with weight at home as a weight. For example, my mother bought new toothpaste and lipstick with120g, 40g,18g and 3.5g..

Both have grams.

I'm very excited to say that the shoe activity has started. I put the shoes on the left side of the homemade balance and the "weight of goods" on the right side. It is best to balance the weight on both sides. Then the sum of the weights is the weight of my shoes. Exactly 86 grams. Hard work pays off! I finally finished my math homework. Mom praised me when she found out.

He also joked with me: "In ancient times, there was a clever Cao Chong as an elephant, but now there is a clever Han Han as a shoe!"

Say that finish, everyone laughed.

It turns out that there are "scales" everywhere in life!

Today, I found a math problem at home.

I found that a cup of cola is 800g, a cup of green tea is 500g, and a cup of iced black tea is unknown, so I added another message-Fan Wen, the flower king of iced black tea.

I calculated according to the teacher's method: 800-200=600, then 600+500= 1 100, and finally1100+800 =1900, so it's a *.

I think there are many math problems in daily life. I hope that children can observe more math problems around them.

4. Primary school students' mathematics newspaper (300 words of fifth-grade mathematics story)

Children, do you know the story of Gauss, a mathematical genius, when he was a child?

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 theme 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 everyone how he worked it out: add 1 to 100, and add 100 to 1, adding two lines, that is:

1+2+3+4+ .....+96+97+98+99+ 100

100+99+98+97+96+ .....+4+3+2+ 1

= 10 1+ 10 1+ 10 1+ .....+ 10 1+ 10 1+ 10 1+ 10 1

* * * There are one hundred sums 10 1, but the formula is repeated twice, so the answer is equal to < 5050 & gt.

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!

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 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 great 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.

Children's song competition

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.

Skills of, and.

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! "

He smiled and said, "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 orders of God and ... and from then on, the mathematics kingdom had a strict order, and no one would violate it.

Xiao Xiong 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 don't study well that we came to teach you a lesson." They 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.

When the champion runs 1, the tortoise runs110. When the champion ran110 mile again, the tortoise ran forward again1100 mile; When the champion runs1100, the tortoise runs forward11000; -In this cycle, the champion will never catch up with the tortoise!

7. A short story about the first volume of mathematics in the fifth grade of primary school.

Tang Priest came to pick peaches.

One day, the Tang Priest told his disciples Wukong, Bajie and Friar Sand to go to Guo Huashan 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 you count three plots, there is still 1 left. Do you calculate how many peaches each of us picked?

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. Calculate, how many peaches did we each pick?

Wukong smiled and said, Master, I'll test you, too. If you count five peaches in my basket, there is 1 left in the end. Calculate, how much will each of us choose?

Tang Priest quickly said how many peaches they each picked. Do you know how many peaches they each picked?

9. The first volume of the fifth grade math diary

Life is inseparable from mathematics.

I used to think that learning to find the least common multiple was boring, and it was really annoying to deal with the problem of finding the least common multiple of 1 1 and 12 all day. I have always felt that it is useless to learn this knowledge in my life. However, one thing changed my view.

That was not long ago. Grandpa and I took the No.2 bus to the Youth Palace. Just as the bus was about to leave, 1 the bus just started at the same time as us. At this time, grandpa looked at the two cars in front of him and suddenly smiled and said to me, "Zequn, grandpa has a question to test you, okay?" I answered confidently: "OK!" "Then listen carefully. If the 1 bus runs every 3 minutes and the No.2 bus runs every 5 minutes, how many minutes does it take for the two cars to leave at the same time? " I paused and said, "Grandpa, your question still needs one condition: the starting point of bus 1 and the starting point of bus 2 are in the same place." Grandpa listened to my words, suddenly patted his clever bald head and said with a smile, "I am a doctor of mathematics, and my questions are not rigorous enough, or Zequn is thoughtful." Grandpa and I laughed happily. Then grandpa said, "OK, now suppose it's the same starting point. What do you think is the solution? " I thought about it and blurted out, "15 minutes. Because 3 and 5 are prime numbers, finding the least common multiple of prime numbers is equal to the product of these two numbers (3×5= 15), so 15 is their least common multiple, that is, it takes at least 15 minutes for two cars to start at the same time. "Grandpa praised me:" Correct answer! 100 integral. "Yes! Listen to grandpa. I raised my hands happily.

In this case, I understand a truth: mathematical knowledge is really everywhere in real life.
