The thinking of primary school students is in the specific calculation stage, right?
According to Piaget's theory, children between the ages of 7 to 11 were in the stage of specific operations. Children in primary school were usually in this age group, so the thinking of primary school students was in the stage of specific operations. This stage had the following characteristics: 1. ** Conservation **: Children can grasp the essence of a concept from various specific changes. Understanding conservation depends on whether children can understand identity, compensation, and reversibility. For example, in mathematics, he could understand problems related to identity such as addition and the commutativity law of multiplication, problems related to compensation such as addition and the association law of multiplication, and problems related to reversibility such as "Subtraction is the inverse operation of addition, division is the inverse operation of multiplication". 2. ** Can perform cluster operations **: This includes five aspects: combination, reversal, combination, identity, and repetition. However, these operations cannot be separated from the support of specific things. Moreover, they are scattered and have not yet formed a complete system. 3. [Class Calculation: Able to find a single characteristic contained in a series of objects and group them according to this characteristic. This ability is closely related to multi-disciplinary learning and daily life.] For example, in Chinese and English questions, finding different types of content, writing sentences with synonymous words, finding the central sentence of the article, etc., and in mathematics, finding the pattern question type, etc. were all related to the ability to classify operations. 4. ** Sorting Operation **: Able to sort from big to small or from small to big. If there was a problem with checking the numbers in order, it might be wrong to do the sorting questions by size, and it would be difficult to understand the principle of transitivity. 5. Spatial reasoning ability development: In terms of direction, at the age of seven or eight, one can use their own perspective to understand the direction (mental rotation). At the age of eight to ten, one can use words such as front, back, left, and right to express directions. In terms of maps, at the age of seven to eleven, one can gradually understand maps, draw maps, and deal with situations where the direction of the map does not match the space it represents.

What stage is the thinking of a primary school student?
The thinking of primary school students was in the transition stage from concrete image thinking to abstract logical thinking, and there was an obvious critical period in this transition. It was generally believed that the critical period was in the fourth grade (10 - 11 years old). In the lower grades (first and second grade), their thinking was more inclined to the level of visual images, and they mainly thought in specific images. For example, in the essay study, the first and second grade students mainly cultivated the ability of "writing". They should guide the students to be interested in writing, to form sentences with connecting words, to express fluently, and to pay attention to the basic role of oral expression in written expression. This also reflected the characteristics of the students 'thinking development at this time. In the middle grades (third and fourth grades), they were at the level of image abstract and began to transition from concrete image thinking to abstract logical thinking. This was a turning point or critical period. In the essay learning, from writing words to writing a paragraph and a complete essay, it was necessary to pay attention to cultivating the standard of using words, which also reflected the gradual development of thinking ability. The upper grades (fifth and sixth grades) were at the preliminary level of abstract essence, and their abstract logical thinking had further development. The requirements for essay learning were more comprehensive, such as mastering the methods of observing life, accumulating materials, expressing feelings, using a variety of rhetorical techniques and writing methods, etc., reflecting the development of students 'thinking ability at this stage. In mathematics and other disciplines, this kind of thinking was also reflected in the stages of development. In the lower grades, they might need to use concrete things to understand mathematical concepts. As they advanced in grade, they would gradually be able to understand abstract mathematical concepts and carry out more complicated reasoning operations. Their abstract and logical thinking would continue to increase. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Cultivate the flexibility of the thinking of primary school students
The key to cultivating students 'flexibility in thinking was innovative thinking, which included a variety of ways of thinking. Divergent thinking takes a certain object as a starting point and inspires new ideas through imagination and speculation. For example, when students were asked to describe the "0" in composition teaching, they could give a variety of answers, such as the cold moon, the red sun, etc. They could also express different meanings such as the starting point or the end point. This would help to break through the shackles of traditional concepts and give full play to their free imagination and creativity, so that their thoughts could continue to expand and extend. Reverse thinking was to think from the opposite side of conventional thinking and break the mindset. For example, in the teaching of phenomenon and essence, for " seeing is not necessarily believing ", the bending of chopsticks in the water was caused by light refraction, but in fact, it was straight; for the idiom " changing at the sight of something different ", most people criticized it, but a few people put forward the opposite view from a positive and aggressive perspective. This kind of reverse thinking could put forward unique insights. Lateral-thinking was the use of concepts, knowledge, or phenomena from other fields to solve specific problems. For example, Lu Ban was inspired by grass to invent saws, the Wright brothers were inspired by birds to fly, and people were inspired by bats to invent radars. When thinking about problems, they could find solutions by linking existing knowledge. On the other hand, he used a comprehensive, dichotomous, and developing perspective to analyze problems. Take " The Foolish Old Man Moves Mountains " for example. Although the Foolish Old Man's spirit was commendable, the method of moving mountains was not necessarily appropriate. In reality, hard work was not as good as clever work. When dealing with problems, one had to think carefully and find the best solution. In the process of education and teaching, teachers actively create conditions, change teaching methods, and pay attention to the training of students 'thinking ability, which can continuously improve the flexibility of students' thinking. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Primary school students read novels, right?
Primary school students reading novels may have a negative impact on their vision, reading, and cognitive abilities. Therefore, it is not recommended for them to read novels for a long time and at close range. Reading novels can help primary school students improve their vocabulary, comprehension and imagination, but they also need to pay attention to the time they read to ensure that they have enough rest and activity time. Parents should supervise the reading time of primary school students and provide them with novels suitable for their age and level to help them develop good reading habits. At the same time, parents can also introduce some useful reading materials such as poems, fairy tales and popular science books to the primary school students to promote the development of their language and thinking ability.
Songs for primary school students suitable for stage performances
The following songs were suitable for primary school students to perform on stage: " 197653,"" Day Lily,"" Come to the Nusic,"" Little White Boat,"" Free Flight,"" Picking Vegetables,"" Starry Moon,"" Courage Explosion,"" Big Dreamer," and " Grass." <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are the ten characteristics of primary school students 'thinking?
At present, the following characteristics of primary school students 'thinking could be summarized: 1. Focus on concrete images: concrete things are more helpful for primary school students to think. Compared to abstract concepts, concrete images can help them understand better. For example, using the image of a cat to explain "cat is a cat" will make it easier for primary school students to understand. 2. The transition to abstract logical thinking: Throughout primary school, children's thinking gradually transitioned to abstract logical thinking, but it still had a lot of specifics. The two forms of thinking intertwined and developed, and this kind of logical thinking was still largely related to perceptual experience and still had a large component of concrete images. 3. There is a transition period: 10 - 11 years old is the key age for the development of thinking from concrete image thinking to abstract logic. 4. Imbalanced: The speed of development of thinking is fast and slow. It develops faster in some time periods and slower in some time periods. 5. Concreteness of thinking: In primary school, children's thinking is still very concrete during the transition to abstract logical thinking. 6. Semi-logical state (Grade 1): The thinking of Grade 1 students is in the transition from the pre-operation stage to the specific operation stage. Their thinking is in a semi-logical state, and their thinking is mainly in images. 7. The development characteristics of intuitive action thinking, concrete image thinking, and abstract logic thinking: primary school students mainly focus on concrete image thinking, while middle school students focus on abstract logic thinking. 8. Understanding the concept of conservation: For example, the understanding of conservation problems such as whether the amount of water changes when it is converted between different containers can reflect the characteristics of his thinking. 9. Spatial reasoning ability: It is reflected in the understanding of directions and maps. For example, a five or six-year-old child is prone to making mistakes when answering the left or right objects of others because they use their own framework. 10. When understanding abstract mathematical concepts, one needed to use specific forms. For example, when learning the area formula of the quadrilateral and the echelon, the story form of the big turtle puzzle could make the child understand it more thoroughly and clearly. It should be noted that the characteristics summarized so far were not necessarily exactly ten aspects. They were just trying to summarize the characteristics of primary school students 'thinking from multiple perspectives. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Primary school students examine questions and train their thinking.
The following are some examples of the answers to some primary school students 'questions: ** 1. Numeric Patterns ** 1. Fill in the blanks according to the rules, such as 10, 7, 4 (). - The idea was to observe the difference between the numbers. 10 - 7 = 3, 7 - 4 = 3. The rule was that the latter number was 3 less than the previous number, so the number in the parenthesis should be 1. ** 2. Numeric Operations ** 1. One and one forty-second plus two and one fifty-sixth plus three and one seventy-second. - The idea was to first add the whole numbers 1, 2, and 3 together to get 6. For the fraction part, 1/42 could be converted into 1/6 minus 1/7, 1/56 could be converted into 1/7 minus 1/8, and 1/72 could be converted into 1/8 minus 1/9. After adding up, the intermediate scores could be eliminated, and the final result was 1/6 minus 1/9. The general score was calculated as 3/18 minus 2/18, which was 1/18. The final result was 6 and 1/18. ** 3. Numeric Puzzles ** 1. For example, a circle, a five-pointed star, and a triangle would add up to 888. - [Thinking: If we first solve the numbers represented by each graph according to the conventional thinking, the process will be more complicated.] However, if the three numbers were the same, they could divide 888 by 3 to get 296. That meant that the number represented by each figure was 296. ** 4. Practical-use category ** 1. Xiao Ming was seven years old this year.

What are the methods of the primary school students 'way of thinking?
Here are some ways to deal with the elementary school question: ** 1. Mathematics Questions ** 1. ** Using the mnemonic chant ** - For the problem of profit and loss, for example, if the children divided the watermelons, each of them would get 10 watermelons less than 9 watermelons, and each of them would get 8 watermelons more than 7 watermelons. First, add the small number and the large number (9 + 7), then subtract the two distribution methods (10 - 8), and finally divide them to get the number of people, which is (9+7)/(10 - 8)=8 people. 2. ** Inference Analysis ** - For example, if the sum of two numbers was 2016, and one of the numbers had a single digit of 0, removing 0 would be exactly twice the number of the other number. One needed to first deduce the relationship between the two numbers. One number was 10 times the other number after removing the zero. Since the number after removing the zero was exactly 2 times the other number, this number was 20 times the other number. Then, he calculated the two numbers according to the sum of the two numbers, 2016. The smaller number was 2016/(20 + 1)=96, and the larger number was 20×96 = 1920. 3. ** Clear concept and calculation sequence ** - For simple math problems like Xiaoming being 15 years old and Xiaoming's mother being two years older than Xiaoming, one had to first accurately write down the formula 15×2+2 = 32 years old according to the question. For subsequent derivative questions, such as how old Xiaoming's mother was when she gave birth to Xiaoming, one would then subtract 32 - 15 = 17 years old. At the same time, when calculating the number of people and the number of items, you have to pay attention to repeated counting. For example, if the students line up to do exercises, counting from the front, Xiaoming is ranked fourth. Counting from the back, Xiaoming is ranked fifth. The number of people in this team is 4+5 - 1 = 8 people. ** 2. Question on logical reasoning ** 1. ** Ingenious hypothesis and question ** - When faced with two people who could only nod and shake their heads and could not be sure whether they were telling the truth or not (one person only told the truth, the other only told lies) and were trying to judge the situation of two roads (one leading to the capital and the other leading to a small village), one could ask one of them,"If I ask him (the other person) whether this road (randomly pointing to a road) leads to the capital, how would he answer?" Then, he would judge the correct path based on the person's nod or shake of the head. This was because no matter if they were asked the truth or the lie, their answers would be "true" or "false" on the basis of "true" or "false", resulting in the opposite result. 2. ** Reasoning relationship based on conditions ** - In the Character Class Reasoning Problem, for example, there were three people, Little Wang, Little Zhang, and Little Zhao. One of them went into business, one was admitted to a key university, and the other joined the army. They knew that Little Zhao was older than a soldier, and university students were younger than Little Zhang. Little Wang's age was different from university students. Through these conditions, he gradually inferred the relationship between the characters. Because Xiao Zhao was older than the soldier, Xiao Zhao was not a soldier; because the university student's age was not Xiao Wang or Xiao Zhang, Xiao Zhao was a university student; and then according to the age relationship, Xiao Zhang went to the sea to do business, and Xiao Wang joined the army. ** 3. Cultivation of thinking habits ** 1. ** Strengthening the Knowledge System ** - The teacher had to guide the students to review and sort out the knowledge they had learned before. For example, when learning the area of a triangle, they had to review the knowledge of the area of a triangle, a rectangular, and a quadrilateral. This was to avoid the students from making mistakes due to their lack of basic computing ability, unclear understanding of concepts, and lack of understanding of the formula derivation process. 2. ** Pay attention to the completeness of knowledge ** - The teacher had to train the students to think independently and ensure that every student was truly involved in the progress of the classroom. By designing activities, screening exercises for error-prone questions, letting students talk about the whole process of thinking, and repeatedly practicing important knowledge points with homework or small tests, students could improve the cohesiveness of their thinking and the accuracy of their questions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Floor calculation formula primary school
If it was a formula to calculate the golden floor, for the elevator room, the total number of floors could be divided by 2, and the result was added with 1, which was "N floors/2+1". The floor calculated by this formula usually had better lighting, space, ventilation, vision, and so on. The formula for calculating the number of floors is (number of floors x storey height 1 x square 3-actual floor distance)/(storey height 2 x square 3).
