Reflections on reading math books 1 century old man Bing Xin said, "Read well, read well, read well." "Reading a good book can enrich your mind; Reading a good book can help you distinguish right from wrong; Reading a good book can make you have love and know manners. " Let us like reading, love reading, and get happiness and happiness from reading. This is the constant pursuit of teachers and students in our second experimental primary school. I recently read the book Mathematical Story. This book is closely related to real life. It is based on textbooks and implements the standard concept of the new curriculum. It tells a wonderful story from the aspects of numbers, applications, calculation, algebra, geometry, statistics, probability and logical reasoning. It can not only give students wisdom, but also give them strength and gain happiness on the road of education. The math here is not boring numbers, but lively and interesting stories, and the small plates behind each story also add a lot of color to it.
Let's start with the mysterious number 1. Let's start with a short story. The Digital Kingdom held a meeting, mainly to discuss the uses of various digital members. In addition, it is a number with special significance. We all know that when sorting, it means first. The so-called first place is the king or leader, even the monitor or captain. But when measuring the quantity of goods, it is also used to mean "small" and "less". At this time 1 is just the opposite of the meaning of the representative order just said. Even in a small place, it can shine brightly. Have you ever heard the phrase "in a word, it's worth a thousand dollars"? Comparing "one" and "thousand" together here highlights the power of "one". There are also famous sentences such as "a journey of a thousand miles begins with a single step" and "pushing ten", which are enough to prove the magic.
Some abstract things in mathematics have become living things because numbers are the basis of mathematics learning, numbers are intelligent elves, and there are interesting stories behind each number. Who created 0? What are the classifications of infinite numbers? What interesting stories will happen between numbers? How to maintain the order of digital kingdom? These interesting math problems are all talked about in this book. There is an extraordinary story behind every ordinary number, which will open a completely different mathematical world for us. Here, mathematics is no longer boring, and numbers have become elves full of wisdom. Interesting math problems, flexible solutions. It doesn't require you to work out the answer, but it wants you to extract a mathematical thinking from these stories. Later in this story, the hidden secrets of odd and even numbers will test you. Han Xin led troops to defeat enemy soldiers repeatedly, so he rewarded the three armed forces and held a tug-of-war competition. The player on the left is three soldiers and two soldiers, and the player on the right is four soldiers 1 soldier. Before the game, I knew that the strength of four soldiers is equal to five soldiers, but the two soldiers on the left are twin brothers and have great strength. Their strength is the sum of the strength of two soldiers plus 1 soldier. Han Xin said victory or defeat before the game, and the result after the game was exactly what Han Xin said. So which side does Han Xin want to win? Interesting mathematical problems like this fully reflect the extraction of a mathematical thinking in the story. There are also leisure bars, thinking development training camps, problem through trains and so on to help you understand mathematics knowledge. I believe this book will inspire children to bid farewell to ordinary and mediocre, and become better in relaxed stories.
Reflection on Reading Math Books 2 In this summer vacation, I read a book called Ma Xiaotiao Playing Math, from which I learned a lot of math knowledge and many math problems in my life.
For example, the character Tang Fei in the book wants to be as good at solving crimes as Sherlock Holmes. He decided to look for opportunities outside, so he invited Mao Chao and Zhang Da to go with him. When they were walking in the park, they saw a car accidentally hit an old man and then turned around and drove away. Tang Fei and others hurried over and helped grandpa up. Tang Fei thought, this is a good opportunity, but the car runs too fast and I don't know the license plate number of the car. Zhang Da said: I remember the license plate number, which is four digits. 1000 is more than1000. Mao Chao went on to say: Ten digits are twice the hundred digits, 1, and one digit is 2 less than ten digits. Tang Fei thought hard and finally came up with the license plate number: 1497. Finally, the car was finally captured by the police.
From this incident, I know that there are some small things in life that we should observe and think about.
Reflection on reading math books 3 Today, my father bought me a book. I saw Ma Xiaotiao playing math. What book is it? So I read it with relish, and I found the book really interesting. One of the unforgettable stories is the poker game.
Here's the story. A magician asked an audience to draw a playing card and asked the audience not to show it to him, but to show it to other audiences. Then the magician gave the audience a formula, multiplying the number on the drawn playing cards by 2, adding 3, multiplying 5, and finally subtracting 25 from the product. Then he told him the result of the calculation. After the audience finished the calculation, he told the magician the result of 50. I saw the magician pull out a card with the number 6 written on it and show it to the audience. The audience thought it was incredible. Later, they tried the same method several times, and they were all right. The audience gave a shout of admiration. In fact, the magician used a mathematical formula. He first added the result to 10, and then divided the sum by 10, and the result came out.
There are many such wonderful math games, which let us master the learning methods while playing. It's really great!
During the summer vacation, my mother bought me a book, and I was quickly attracted by the title, "Ma Xiaotiao Plays Mathematics". Usually everyone studies math, but Ma Xiaotiao turned it into "playing math". I find it very interesting. How to play math? With this in mind, I opened my book and began to read. This is very different and interesting.
The author tells mathematics in an easy-to-understand way and sets many interesting stories. I like snails climbing fish tanks and field competitions.
Every story has a math problem that Ma Xiaotiao can solve. Ma Xiaotiao is a smart and happy student. He has positive energy and can keep a positive attitude when encountering various problems in life. He loves to play, make trouble, cry and laugh. His grades are generally affectionate and sincere, and he is an honest and kind student. I envy him and admire him even more.
After reading the book "Ma Xiaotiao Plays Mathematics", I also understand the tricks of learning mathematics. No matter how big the problem is, as long as we are willing to work hard, we will certainly find a solution. Mathematics can be played, so can Chinese. Let's play the word puzzle as a game!
In the summer vacation, I read the book "Where is Mathematics". The main screenwriters are Tang and Peng Yucheng. These two literary writers are very famous, and I have read many of their books.
"Where is the math?" Explained a lot of interesting math knowledge, and made it easy for me to understand with stories. There are various contents, including multiplication and division estimation, simple operation and understanding of millimeters and kilometers, as well as understanding of perimeter and area. There are many interesting questions in it. Difficult problems sometimes make me think hard, and it takes me more than an hour to work out the answer. Simple problems are also quick, and I can solve them in 5 minutes. What a challenging book.
After reading this book, I found it really interesting. I hope all children can have a look at the math knowledge inside, challenge difficult topics, exercise their own thinking and let themselves grow continuously.
This is the second time that I have watched Ma Xiaotiao play math. Ma Xiaotiao's math book written by Yang is very popular with our students. The book contains 80 interesting math stories, such as Detective. What fascinates me most is Wonderful Dance Formation, which is about the ballet company rehearsing a program. One * * * is divided into two teams, namely 12 and 1 1, and each team is required to form six rows with four people in each row. Linguo Xia doesn't know how to arrange it. As a result, Ma Xiaotiao and Luhmann helped her solve it, which also made me understand how to arrange it.
I like this book very much, because it has taught me many questions that I didn't know before. For example, 100 meter fence should be planted every 5 meters 1 tree. We often get 20 trees without thinking, but we forget both ends, so we plant more trees than the profile 1, which is 2 1 tree.
This book lets us play middle school, learn to play, and stop being bored. This book also teaches us that mathematics is everywhere in life.
The sixth part, I am math, which is an educational essay by Mr. Hua Yinglong. The book is divided into six parts: thinking before class, searching after class, reflecting after class, thinking after class, commenting on class and feeling about life, which records Mr. Hua's teaching and feelings during class. Between the lines, he reveals his reflection on teaching practice and his understanding of life. Therefore, it makes people feel kind, vivid, touching and contains wisdom. After reading it, it is memorable.
Although Mr. Hua is a math teacher, he has rich cultural background. In his articles, from China ancient masters to foreign scholars, he often mentioned the past and discussed the present. From poetry to stories, he can combine what happened in class and quote them properly in all-round reflection. Moreover, he is good at linking teachers' teaching and mathematics with daily life, such as farmers farming and playing basketball. All these are because he loves reading and thinking. I really admire a busy educator who has read so many books in a limited time. In reality, we always complain that we have no time to study, and all our time is spent thinking about how to teach. I don't know that our usual thinking is basically cooking without rice. Without the guidance of theory, even if you want to break your head, it must be something superficial.
Teacher Hua's mind is extremely delicate, and most of her compositions start with details. When the teacher's teaching aid fell to the ground, the child picked it up and gave it to the teacher. The teacher did not thank him. To squat down and talk to the children, to the teacher to clean the blackboard, to how to read the scores, and so on. These details often appear in our class, some of which I pay great attention to and some of which I don't care at all. I am very encouraged to read these articles by Mr. Hua. Yes, education is about starting with small details. If the small ones are not taken seriously, even if the big ones are taken seriously, it will not play a particularly big role in the progress of an educator.
I think the biggest reason for Mr. Hua's success in class comes from his careful thinking before class. For example, in the class of "Angle Measurement", he wondered whether he could create a situation to make students feel the usefulness of measuring angles. After many days of searching, comparing and thinking, he designed a situation in which the big-headed son and the small-headed father matched glasses, but after discussing with the same group of teachers, he denied this situation. Finally, after repeated thinking, he created the design of three slides, which not only made students feel the necessity of measuring angles, but also shortened the distance between math textbooks and students' life experience. At the same time, Mr. Hua also attaches great importance to after-class reflection, and more importantly, the practice after reflection. A student's mistake, a word, and a teacher's casual behavior in class will make him think for a long time. It is his spirit of continuous thinking before, during and after class that makes this Chinese teacher comfortable in class, admired by countless teachers and liked by countless students.
I am Mathematics is a good book. It has taught me a teaching idea and teaching method in vivid form, which will benefit me a lot in my future work.
Thoughts on reading math books. Do you know the function of triangle? Do you know how to calculate the mixed operation? Then play math with me!
It is a book that teaches knowledge according to stories, which gives us a new understanding of boring mathematics. It integrates mathematical problems into stories, not simple and intuitive mathematical formulas, but thinking about mathematical problems in stories. For example, the story of the monkey mother buying peaches and splitting them. It is a fairy tale, telling the cute side of the little monkey, and at the same time, it also puts forward mathematical problems. Let me help the little monkey solve the problem with mathematical knowledge unconsciously. There are many more, such as how to list the division formula, remember the numbers of homophones, and the origin of decimal. I hope you can also read this good book.
A brand-new day has begun. I was doing my homework when I suddenly saw the back of a book. I stopped my homework curiously and turned to pick it up.
This book is really interesting. I seem to be in there. Smart, witty, lively and naughty Ma Xiaotiao brought me into the world of mathematics. Solved one problem after another here. Like turning on the air conditioner. It was cold, and all three families turned on air conditioning. But everyone turns on the air conditioner together, and the power is too high for the line to bear. So everyone has to find a way to solve the actual suffering. Everyone threw the problem to Ma Xiaotiao to deal with. Ma Xiaotiao seriously considered the problem, and made a practical investigation, and finally solved everyone's problems reasonably. It turns out that the power consumption of air conditioners can be calculated under the same power, and the power of four air conditioners is the same. Assuming that three air conditioners are on at the same time, the electricity consumption is equal to 24×3=72 hours. Now, on average, each of the four air conditioners can use 72÷4= 18 hours. I find it very interesting.
I like this book. He integrated mathematical knowledge into the story, so that I not only read the story, but also learned knowledge and truth.
The history of mathematical development is also the history of scientific development. At first, babbling created a colorful counting system, and then more and more detailed mathematical branches were established in the rainy season. Today, it has demonstrated its dazzling mathematical achievements in In the Mood for Love. Every step contains hardships and infinite thinking. During this period, how many people devoted their lives to mathematics, which endowed the subject with infinite charm.
The book Selected Lectures on the History of Mathematics first tells a variety of notation, including the tedious notation in hieroglyphics, the unique notation in cuneiform, the simple notation in ancient China, the strange notation that Maya used the head of God as numbers, and the Indo-Arabic numerals that are still in use today. It is not difficult to see from the evolution of the early counting system that even the creation of numbers is arduous. At that time, how to invent a convenient and durable counting method was a crucial foundation for establishing mathematics discipline. It can be said that if there is no initial research and exploration of numbers and counting systems by human beings and efforts are made to create the simplest and most convenient counting methods, the future research on mathematics will be doubly tortuous and difficult.
In the long history of mathematics development, the most important thing is countless mathematicians who have struggled for it all their lives. Because of their bitterness and tears, their rigorous attitude and persistent spirit of exploration, they laid a solid mathematical foundation, thus creating opportunities for the birth of mathematical branches such as plane analytic geometry, calculus and infinite set theory. However, the development history of mathematics is tortuous and arduous, especially the research mileage of mathematicians. Most of the innovative thinking and super-era theory they have bought in their lifetime will not be recognized by the world in their lifetime. When hippasus announced his discovery of incommensurability to other members of the Pythagorean school, the frightened members threw him into the sea; The strong group theory put forward by Galois has been submitted to the Academy of Sciences many times, but the final result is "completely incomprehensible" comments; Cantor, who created the amazing infinite set theory, finally passed away with many regrets and infinite anguish. Abel, a middle school mathematician, is the most talented person. Through countless efforts, he finally proved this eternal puzzle-algebraic equations with five or more degrees have no general formula for finding roots, but they have been met with a series of cold shoulder. Even the "prince of mathematics" Gauss only said, "It's terrible to write such things!" He threw the paper into the pile of books without even reading the text. Although Berlin University had recognized his talent and appointed him as a professor of mathematics at that time, Abel had already died in the devastation of the disease.
Although their theory is praised by the world today, it was ridiculed and reviled at the beginning. Unlike mathematicians who were famous all over the world at that time, as soon as new theories came into being, they were paid attention to by the whole world, and then they continued to study under the light of admiration and glory. Nevertheless, they still believe in themselves, strive independently for their own mathematics career, explore deeply, and further develop and improve their theories. Just like Cantor's confident words: "My theory is as firm as a rock. Anyone who wants to shake it will shoot himself in the foot." This confidence and determination are admirable.
And many mathematicians have one thing in common, that is, their knowledge level includes many other fields besides mathematics. For example, Thales was the earliest mathematician and philosopher in ancient Greece, and he dabbled in almost all fields of human thought and activity at that time; Fermat has rich legal knowledge and is proficient in many languages. Leibniz studied Latin, Greek, rhetoric, arithmetic, logic and music, and also extensively read and studied a large number of philosophical and scientific works. In Euler's works, mathematics is closely related to the application of other sciences, various technical applications and public life. It often provides mathematical methods for solving problems such as mechanics, astronomy, physics, navigation, geography, geodesy, fluid mechanics, ballistics, insurance and demography. It can be seen that if you want to succeed in a subject, you need to master not only the knowledge of the subject, but also the knowledge of other disciplines and fields, and make comprehensive use of it to make this knowledge better serve your own research.
Confidence, determination and knowledge in many fields are important, but teachers are also very helpful to them. Newton was inspired to study the number of streams in Professor Barrow's course, and Euler inherited the mantle of johann bernoulli, the authority of calculus, and became the "incarnation of analysis". With the encouragement and guidance of his teacher Holmbo, Abel solved the unsolved mystery of algebraic equations five or more times. As a swift horse, Galois was discovered by Professor Richard and became the founder of group theory. Cantor founded the infinite set theory under the famous mathematicians Cuomo, Wilstrass and Kroneck, while Hua. A great mathematician often has a diligent teacher behind him. Perhaps their teacher is unknown now, but their efforts and teaching are no less than these mathematicians. It is precisely because of their patient teaching, great support and encouragement that they are given the opportunity to show their edge, and these mathematicians follow the spirit of their teachers humbly, which is worth learning and emulating.
In addition, from the efforts of mathematicians, we can find the necessary process of mathematical research. First of all, we should explore the truth of mathematics from subtle things, discover the existence of problems, or have great interest and research spirit in a certain problem. Many people can do this, just like Newton thought of a falling apple and created the law of gravity. In our daily life, we can all ask questions about some common things, and when we encounter some problems, we have an impulse to break them. Then, we must make unremitting and in-depth exploration. This step is often only a few people can do, but it is the most important step. Without it, all the previous efforts will be in vain. In the face of difficulties, it is often the key to a great start and success to still have the initial impulse and courage to conquer it. But only this kind of impulse and courage is not enough. A great mathematician must also have the spirit of innovation, question the spirit of people's deep-rooted thoughts, break the cult of personality and dogmatism, and have the courage to create his own new ideas, just like Descartes established the coordinate system, Newton and Leibniz established calculus, Gauss established non-Euclidean geometry, Galois established the new concept of group theory, and Cantor firmly believed in infinite set theory.
Generally speaking, the successful experience of these mathematicians has taught us how to prepare for future challenges at this stage. Ideologically, we should cultivate innovative thinking, self-confidence, firm self-belief and fearless spirit in the face of difficulties. In action, we should learn from teachers with an open mind, not shy about asking questions, and actively learn all kinds of knowledge, so as to master and apply it to daily life.
"Liu Hui's tangent circle method is hundreds of years later than the exhaustive method in ancient Greece", "Descartes and Fermat established analytic geometry in the same way", "Newton and Leibniz, two founders, worked hard to establish calculus as an independent discipline" ... In the development of the history of mathematics, many identical research results were repeatedly discovered by human beings, which undoubtedly delayed the development of mathematics. Repeated efforts for the same problem, but I don't know that others have actually solved it. If the world can integrate earlier, exchange mathematical culture with each other better, conduct research and make progress, then it won't take hundreds of years or even longer to take the same detour repeatedly, but it can promote the development of mathematics faster, and perhaps the development speed of mathematics in the world will exceed the current pace.
The book also mentions a condition for the emergence of mathematics: "After practical technological inventions, there will be sciences that are not directly for the needs or satisfaction of life. It first appeared in places where people had leisure, and mathematical science first rose in Egypt because priests there enjoyed enough leisure. " This shows the importance of leisure for the rise of science. Indeed, people have no time to invent science when the problem of food and clothing has not been solved, and when mental labor and physical labor have not been separated. Only by enjoying leisure can people have enough time and energy to spend on scientific creation. Only when they play with numbers at first, will they gradually explore deeply, find mathematical problems from trivial matters in life, create puzzles and then solve them, so that today's mathematics discipline can come step by step. If there is no leisure, there will probably be nothing behind. Similarly, as students, we also need to take time out to study math seriously. If it is difficult to finish our daily homework on time, how can we solve this math problem?
The development of mathematics is still very long, and there are still many ways to go. As Newton said, we are just children playing by the sea. There is an ocean of unknown truth before us, and the infinite charm of mathematics is buried in it, waiting for us to explore and explore.
Reflections on reading math books 10 This summer vacation, my mother took me to the city's popular bookstore and recommended the book Interesting Mathematics to me. I just saw the title and thought it was another tutorial book. What is there to see? Mom suggested that I read it first. After reading it, I was attracted by the content of the book. The content of this book is really interesting. No wonder it's called interesting math.
This book introduces educational math stories with many interesting math game activities, such as putting leaves, military games, filling magic squares, finding "harmony" from magic squares into known four-dimensional arrays, arranging equations according to practical problems, collecting data, sorting out data and analyzing data ... Every math activity is the best extracurricular training to cultivate thinking ability, imagination and practical ability. Education through fun is a good book for our primary school students to carry out interesting education and training.
I took it out as soon as I was free during the holiday. Many games in the book were completed by my parents together. When playing in middle school and school, time passed unconsciously. In a relaxed and happy atmosphere, I not only learned a lot of math knowledge, but also deeply realized the love of my parents. Now I have been fascinated by interesting mathematics and become good friends with it.
Interesting math is really interesting.
Reflections on reading math books 1 1 Whenever we are studying, we will always encounter some difficulties and always say, "Reading is boring."
I read a book called King of Interesting Mathematics today, which is full of interesting stories. Whenever students are tired of studying, they can read this book, which can integrate boring knowledge into interesting stories. What will happen?
The interesting king of mathematics aroused our interest in mathematics. This book seems to have brought me to the fairy tale world: every short story has vivid pictures, which are very interesting and readable. Every story contains a math problem, which is shallow and deep. At the end of the story, the problem has a correct solution and a clever answer.
Mathematics is an important basic subject in this society. This is very important. There are three sentences: mathematics is the weapon of the four modernizations, mathematics is the foundation of other sciences, and mathematics is gymnastics to exercise thinking. There are many stories in it. For example, there is such an interesting story. Donkeys and horses carry grain into the city together. After walking for a while, the donkey refused to walk. The donkey said to the horse, "Brother Ma, how heavy is your back?" The horse gave the donkey a question. Besides, the donkey worked out how much the horse carried, and he worked out how much he carried, so he doesn't complain now.
After listening, you will know some math knowledge in the future, and you will certainly know some stories that teach you how to be a man.
After reading this book, I feel that it is well written. The book also shows the activities of "telling stories and doing exercises". Learning is intense and should be more interesting. I hope that after reading this book, children will learn easily and vigorously, and get the best learning effect.
Thoughts after reading a math book 12 It turns out that math is also so useful in life: In Zhi Dou Spider Spirit, Bajie is surrounded by four banshees, and he wants to kill the spider spirit first, but he doesn't know her transformed position. However, math observed that the position turned clockwise, and it returned to its original position every four times. According to this rule, a division formula can be listed: (number of array changes)
Another time, in Wukong's Monkey Show episode, 1 ~ 66 counted off (in the order of one, two, one and two, you may report yourself until the last one is yourself, and Wukong told the math monkey not to count off). Wukong asked the math monkey to point out himself once, and the math monkey immediately said, "No.64, you are Wukong, come out." It turns out that he thinks like this: there are five sheep, a row of nine sheep, and the last one must be No.8, and his laws are 2,4 = 2× 2, 8 = 2× 2× 2 ... For 66, the most characteristic number is 64, because 64=2×2×2×2. As a result, the Monkey King was found.
So I must study mathematics and solve some small problems in my life in the future.
Reflections on reading math books 13 This summer, my father bought me a math desert island adventure.
There are ten small books in this book, which took me a long time to finish. Now I want to introduce the characters in it, including Yi Yi, Roque, Libic, Princess Huahua, the king and other main characters. They have produced many interesting topics.
A monster visited the digital kingdom. It saw the numbers 5, 24 and 44, but only ate 24 and 44. 14, 35, 100 to attack the monster, and the monster only swallowed 100, 35, but it was safe. Why don't monsters eat all the numbers?
I thought about it for a long time, but I didn't come up with it. Finally, I realized that monsters only eat multiples of 4, 24, 44, 100. Because they are all multiples of 4, others are not multiples of 4, so monsters don't eat. Interesting topic, hmm, so let me know that there is no rigid answer to numbers. If you think too much, there must be many answers. Students are welcome to get together at the beginning of school.
