1, interesting math story

Thales saw that people were reading the notice, so he went to check it. It turned out that the notice said that we would always look for the smartest person in the world to measure the height of the pyramid. So I went to Pharaoh.

Pharaoh asked Thales what tools he used to measure the pyramids. Thales said he only used a stick and a ruler. He put the stick next to the pyramid. When the shadow of the stick was as long as the stick, 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.

2. Interesting math story

During the Warring States Period, Qi Weiwang and Tian Ji raced, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and each horse race is a bet of several thousand dollars. Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose.

However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang's horse, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and won a lot of money. This is an example of China's ancient substitution game theory to solve problems.

(4) Math stories suitable for junior two students.

Mathematical genius gauss

1960 1777 On April 30th, Gauss was born in a peasant family in Germany. When I was a child, Gauss liked math very much. When learning English, Gauss Chang Quan often lies in the yard and counts chickens. When he was a little older, he followed his neighbor's children to do math problems, which were fast and accurate every time. After school, Gauss is particularly interested in mathematics. But math teachers look down on rural children and often make things difficult for students. Once, the teacher asked them to sum from 1 to 100, stipulating that they were not allowed to go home for dinner unless they could do it. The children began to calculate at once. But there are too many figures. If you do the math, you will be wrong if you are not careful. Just as everyone was in a hurry, Gauss stood up and reported, "Teacher, I did it." When reading the novel, the teacher said without looking up, "You must be wrong. Recalculate. " But Gauss was so confident that he took the answer sheet to the teacher to show him. Suddenly, the teacher's eyes widened. 5050! The answer is correct! The teacher asked him in surprise what method he used. Gauss said with confidence: "1+100 =10/,2+99= 10 1, 3+98 =1kloc. Teacher, do you think I did the right thing? " The teacher was ashamed. Since then, he has devoted himself to teaching and even tutored Gauss more carefully. Gauss studies very hard. Later, he made great achievements in mathematics. At the same time, he also made outstanding contributions in astronomy, electromagnetism, geodesy and other scientific fields.

5] What excellent picture books are suitable for senior one and senior two?

Excellent manuscripts suitable for senior one and senior two include Guess how much I love you, Grandpa must have a way, Cloud Bread, Dr. Bloom series, Tell me stories series, My parents.

[6] I need 10 second-grade math stories.

1, mirror problem

Pleasant goat and boiling goat see a mirror hanging on the tree. In the mirror, the wolf points to a clock, and the time on the clock is 50. Cang Lang said, "Do you know the real time? If you don't know how to do it, you are an idiot. If you know how to do it, you sheep are still idiots! "

Boiling sheep thought for a long time and said, "Isn't the time seen in the mirror 10: 50?" Pleasant Goat said, "The object seen in the mirror is opposite to the actual object." Boiling sheep said, "Could it be 2: 20?" Pleasant Goat said, "No, the actual time and the time in the mirror add up to 12." Boiling sheep also began to understand, saying, "I see, the actual time is 1: 00 10."

2, a few corners

Pleasant Goat and Boiling Goat walked for one kilometer and reached the way down the mountain. They saw three equilateral triangles drawn on another piece of paper without crossing. How many angles are there and how many right angles are there? Then the boiling sheep said, "It's not easy." Pleasant Goat said, "Every triangle has three angles, and three triangles make up 339, with nine angles. An equilateral triangle has no right angle. "

3. Multiplication formula

Pleasant Goat and Boiling Goat walked another kilometer. They see a piece of paper that says, "When you see this paper, you should have a good sleep, because this is the last time you sleep.". What is 45 times 1 1? " Boiling sheep said, "It's not easy! First calculate 45* 10 equals 450, and then add 45, which equals 495! " Then Pleasant Goat said, "There is another simple way. 4+5 equals 9. If you put 9 between 4 and 5, it becomes 495! "

4. How long is the rope?

Summer came, and my parents took Xiao Cong to the mall to buy air conditioners. The air conditioner has been selected, and Dad asked the salesman to tie it up. Unfortunately, the salesman has no rope. Xiao Cong volunteered to go to the reception desk to get the rope.

Xiao Cong trotted to the service desk. He said politely, "Hello, uncle! Please give me a 2 cm long rope, I want to tie the air conditioner. " Uncle was taken aback at first, and then smiled and said, are you mistaken? What can a 2 cm long rope bind? This is a 2 meter long rope! "Xiaocong shyly took the rope and ran back. He thought: Yes! 2 cm is only two fingers wide, too short, 2 m =200 cm! No wonder uncle laughed at me!

Son, you can't be careless in math. When we know the unit of length, we should contact life, and never imagine it out of thin air. You see, Xiao Cong made such a big joke because of this. Don't be like him!

Steps 5 and 2 apply the problem.

Pleasant Goat and Boiling Goat just walked one kilometer when they saw a piece of paper on the tree next to a TV set. Gray Wolf gradually appeared on the TV. Big Wolf said, "Seeing you here means that you have passed the first level. However, that question is so simple that even primary school students can do it. You won't know the second question. " Boiling sheep was angered: "We can definitely do it, Big Wolf, we'll see!" " "The big wolf said," Ha ha ha ha, a little more anger, that would be fun! " "

Pleasant Goat and Boiling Goat saw the paper saying, "The white rabbit picked 60 mushrooms, and now there are only 48 left. How many days will it take to finish them? " Pleasant goat and boiling goat said, "What's the problem? It still lacks one condition! " "Pleasant goat said," let's look for clues. "After careful observation, Pleasant Goat and Boiling Goat found that on the back of the paper, this is a two-step application problem. They said, "The white rabbit has picked 60 mushrooms, and it eats 6 every day. Now there are only 48 mushrooms left, and the rest will be eaten in only 8 days. "

What excellent picture books were once suitable for senior one and senior two?

⑻ Are there any extracurricular reading materials suitable for grade two children? They are in Grade Two.

The book "Love Mathematics from an Early Age" is very good. My son is in the second grade and likes it very much. The following is Dangdang's introduction to this set of books:

The picture book "Love Mathematics Since Childhood" won the 5th Korea Publishing Culture Award. It is a necessary book for Korean children's mathematics enlightenment and an auxiliary reading material for many primary school mathematics textbooks in Korea. Suitable for children aged 4~ 10. Compared with the mathematics enlightenment books published at present, it is the most comprehensive, systematic and covers the widest range of mathematics knowledge points, and it has a scientific ranking, so that parents can have laws to follow. But this series is very vivid in the process of telling math knowledge, and the story is very interesting. It is easy for children to fall in love with math! //proct.dangdang/proct.aspx？ proct_id=2 1066742
