Elementary math textbook illustration old edition
There were many problems in the illustrations of the old primary school mathematics textbooks. These illustrations are from the primary school mathematics textbook published by the People's Education Bureau.(Covering the first to sixth grades, approved in 2012 or 2013. The layout design and illustrations were from Beijing's Wu Yong Design Studio). The characters in it had characteristics such as "flat nose bridge, wide eye distance, slanted eyes, and high hairline." The overall appearance was "dull and strange." There were also some inappropriate behaviors, such as wearing a five-pointed star shirt, wearing a red scarf, tilting his head and sticking out his tongue, revealing his private parts, and the child had tattoos. Wearing the Star-Spangled Banner, wearing a red scarf, and the five-pointed star on the flag was drawn wrongly. These illustrations did not meet the aesthetic standards of the Chinese public. There might be a tendency to worship foreign things in their ideology and culture, which caused widespread controversy and criticism. Read more exciting novels for free

Elementary school sixth grade Olympiad math thinking training textbook recommendation
The following are some recommended textbooks suitable for the sixth grade of primary school: 1. ** Gaosi Mathematics textbook + Gaosi Mathematics Competition Guide **: This is a very famous Mathematical Olympiad teaching aid. Many areas (such as Beijing) use it as an entry-level teaching aid for Mathematical Olympiad competitions. It is recommended that children read it at least two to three times. 2. [Learning and Thinking (Big White Version): The difficulty of the questions is high. Many teachers who are not very experienced may not be able to solve them.] If one could complete the questions in the Gaosi Mathematics textbook and the introductory textbook well, they could try to do this book. However, if they did not even win the third prize in the previous Mathematical Olympiad competition, it might be more difficult to do it. 3. ** Mathematical Olympiad 6th grade standard course + exercise selection + ability test three-in-one (by Chen Tuo)**: This is a course specially written for the 6th grade Mathematical Olympiad. 4. **<<Synchronization of Mathematical Olympiad Excellence>> Grade 6 (suitable for Beijing Normal University textbooks)**: It is suitable for students who use Beijing Normal University textbooks to carry out Mathematical Olympiad Excellence. 5. ** Xiong Bin's "Mathematical Olympiad Guide": It has a different style from the Gaosi Mathematics textbook + Guide, but the overall difficulty is the same. You can choose one to learn. 6. ** True questions of previous Mathematical Olympiad competitions (such as Liu Jia's imo Mathematical Olympiad yearbook)**: This is the material closest to the competition itself, but due to the difficulty, it is recommended to use it after a certain foundation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Elementary math calculation notes
The following was a set of notes on elementary school math problems: ** 1. Integer-related operations ** 1. ** Basic Operations ** - The calculation part of numbers included the understanding of the whole number, which was the basis for subsequent calculations. For example, when doing addition, multiplication, and division, one had to first understand the concept of numbers and numbers. 2. ** Simple calculation ** - ** The application of the multiplication distribution law ** - For formulas such as 24x63 + 46x28, the multiplication distribution law could be applied by splitting the numbers. If 24 was split into 4 x 6 and 63 into 7 x 9, 4 and 7 would appear. 4 x 7 was 28, which was related to 28 in the following formula. Using the commutative law of multiplication and the law of association, 4 multiplied by 7 was 28, 6 multiplied by 9 was 54, and the formula became 28×54+46×28. After extracting the common factor 28, it was 28×(54 + 46)=28×100 = 2800. - ** Use of special numbers ** - In calculations, some numbers have special relationships, such as multiplying 125 and 8 to get 1000. When calculating 7/125, because 125×8 = 1000, the quotient of 125 was multiplied by 8 times to become 1000. To keep the quotient unchanged, the quotient of 7 was also multiplied by 8 times to become 56, so the result was 56/1000 = 0.056. 3. ** Special calculation ** - Special training could be carried out for all kinds of questions in the Four Mathematical Operations. For example, the calculation of 49×49+99 required one to master the order of the four arithmetic operations. First, multiply and then add. ** 2. Key Points of Calculation for Different Grades ** 1. ** Year 1 ** - There were calculation methods like the dismantling and complementing method that could be used for the intensive training of first-year mathematics calculation questions. 2. ** Fourth grade ** - There were key calculation questions in the whole book, which could be used for classified training. If the calculation questions were not mastered well, special training should be carried out because calculation questions were an important support for learning mathematics well and getting high marks on the exam. Parents should pay attention to their children's learning situation. During the summer vacation, they can find out their children's weak points in calculation through the test papers, and carry out missing and filling in or targeted training. Even if the child has reached the fifth grade, the calculation questions in the fourth grade are still worth practicing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Elementary school English textbook reported
There were many cases of primary school English textbooks being reported. For example, the "Smart English" textbook used by a primary school in Shanghai was reported by parents. The parents said that it was a textbook outside of compulsory education and that it increased the learning burden of primary school students. The Shanghai Education Bureau asked the school to no longer use the textbook in regular learning. There was also the compulsory education textbook for the sixth grade," English," published by the Foreign Language Teaching and Research Press, which was suspected to be a " poisonous teaching material ". Because it included examples of China girls marrying " foreigners ", parents felt that it was inappropriate to convey such values to sixth graders. In addition, parents also reported the appearance of illegal entertainer Kris Wu in the primary school English teaching of the People's Education Press, believing that it would have a bad influence on their children. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Funny story about math textbook characters
There was a character in my math textbook who was a little wizard. He was supposed to solve complex equations but always ended up using his magic wand to make the numbers dance around. For example, when faced with a quadratic equation, instead of using the formula, he made the coefficients turn into little animals and tried to make them arrange in the right order for the solution. It was a very funny way to show how not to do math properly.
Elementary math, math stories, mathematician Gauss's stories
Here are some interesting facts about Gauss: - ** Demonstrated mathematical talent at an early age **: Gauss was able to correct his father's debt accounts at the age of three. At that time, his father was the foreman of the clay factory. He paid the workers every Saturday. After the accounts were calculated and the salary was paid, the three-year-old Gauss stood up and pointed out that his father had miscalculated and said the correct number. It turned out that he was lying on the floor and secretly calculated the wages. After the calculation, it proved that Little Gauss was correct, which surprised the adults. - ** Arithmetic Sequence Summation **: Gauss mastered the arithmetic sequence Summation Method when he was 9 years old. There was a widely circulated (but controversial) story about him calculating the sum of the numbers from 1 to 100. However, according to the research of mathematics historians, the teacher Boutner gave the children a more difficult arithmetic progression sum problem: 81297+81495+81693+…+100899. After Boutner finished the problem, Gauss calculated the answer and handed in the slate. At that time, Gauss was the only child in the class who calculated the correct answer. - ** Solve a Millennial Mathematics Problem **: - At the age of 19, Gauss solved a problem that had troubled mathematicians for more than 2000 years. After Eugene proposed the rule construction method, there were many problems in the rule construction method of the regular hexagon. The rule construction method of the regular hexagon was difficult for many mathematicians and was even considered impossible. However, Gauss obtained the relevant formula when he studied this problem on March 30, 1796, which proved its feasibility. This result shocked the entire mathematics community. - When he was 19 years old, his teacher mistakenly gave Gauss an unsolved math problem left behind by Archmedes in 2000 as homework. Gauss worked hard for one night and solved it. The next day, he was embarrassed to say that he was too stupid to solve it all night. It should be known that Archmedes could not solve this problem, and Newton could not solve it even after spending his entire life. - ** School performance **: Gauss had solved math problems that even his teachers couldn't solve. His talent caught the attention of a nobleman, who sponsored him to receive a better education. At the age of 18, he discovered a method to solve an algebraic equation and published his first paper at the age of 19. - ** Early growth assistance **: Gauss was born in a poor family in Brunswick, Germany. When he grew up, his uncle Fred Erich discovered his intelligence and invested in developing his intelligence, which was very important to Gauss 'success. His mother, Rozeya, was also very supportive of him. Even though her family's financial situation was difficult to support, when Gauss was 19 years old and had made many achievements in mathematics, she still asked her friends if Gauss would make further progress in the future. When she learned that her son would become the greatest mathematician in Europe, she was so excited that tears welled up in her eyes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Which is better, the 2020 edition or the 2021 edition of the national examination textbook?
The 2020 and 2021 national examination textbooks were basically the same. There was not much difference, but there were some changes in the current politics section. Therefore, it was difficult to simply determine which version was better. If the examinee paid more attention to the updated content of the current politics section, the 2021 version might be more suitable; if the examinee had other channels to obtain the current politics content, the 2020 version could also meet the demand. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
