How to write the summary of the knowledge points of the primary school mathematics transformation thought
Transformation of thought was an important mathematical way of thinking in primary school mathematics. ** I. Concepts and Connotation ** Changing one's thinking was to change the direction of the problem from a different perspective when solving a problem. Its purpose was to find the best way to transform unknown, unfamiliar, and complex problems into known, familiar, and simple problems through deduction and induction, so as to solve the problem smoothly. ** 2. The specific operation method ** 1. ** Form Transformation ** - It was more common in the calculation of the area or volume of a geometric figure. For example, when deducing the area of a quadrilateral, the quadrilateral was transformed into a rectangular shape; when deducing the area of a triangle, the triangle was transformed into a quadrilateral; when deducing the area formula of a circle, the circle was transformed into a rectangular shape; when deducing the volume formula of a cylinder, the cylinder was transformed into a cuboid; when deducing the volume formula of a cone, the cone was transformed into a cylinder, etc. 2. ** Digital Conversion ** - In terms of calculation, for example, in the division of decimals, the decimals were converted into the numbers for calculation, and in the division operation, the division could be converted into the multiplication for calculation. When comparing the sizes of two formulas, you can also convert them. For example, when comparing the sizes of 25 + 47 and 35+35, you can convert them into a form that is more convenient for comparison. For example, you can convert 25 + 47 into 35 + 37, or 35 + 35 into 25+45. You can compare the sizes without calculating. - It was also reflected in the estimation. For example, when judging whether the result of 71 - 19 was greater or less than 50, it could be converted into 71 - 20 or 70 - 20 to think. This would allow students to master the estimation knowledge in a relaxed atmosphere and feel the power of transformation. 3. ** Arithmetic Conversion ** - In the calculation of multiplying two or three digits by one digit, the whole ten or hundred digits multiplied by one digit were first converted into a table multiplication calculation, and then the corresponding number of zeros was added to the end of the product. In solving an equation, as in fourth-grade math, the calculation on the left side of the equation could be converted to a form that could use the multiplication distribution law. ** 3. An example of practical application ** 1. ** Find the volume of an irregular object ** - For example, to find the volume of an irregular stone, because its shape was irregular, it could not be directly calculated with the three-dimensional figure volume formula learned in primary school. For example, if an irregular stone was immersed in a rectangular water tank, the volume of the irregular stone would be converted into the volume of the rectangular water by observing the height of the water surface rising. 2. ** Conversion of numerical relationships ** - For a problem like the formula AB - b = 20, it could be transformed into a vertical formula by analysis. According to b - b = 0, without borrowing, a directly fell to 2, and then the value of b was calculated by substitution. ** IV. Summing Up ** Transforming thoughts was a very practical way of thinking in primary school mathematics learning. It ran through many knowledge blocks such as geometry, calculation, estimation, and so on. It could help students simplify complex problems, cultivate students 'mathematical thinking ability, improve the efficiency of solving problems, and lay a good foundation for subsequent mathematics learning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

300 high school biology knowledge points summary
The following is a summary of some high school biology knowledge points: 1. The relationship between chemical elements and organisms: organisms contain a variety of chemical elements. These elements have different functions and effects in the body, such as forming compounds and participating in physiological processes. 2. The list of compounds in the cell: There are many kinds of compounds in the cell, such as sugar, fat, protein, and nuclear acid. Each of them has different structures and functions. For example, sugar is the main energy material, fat can store energy, and so on. 3. Nucleic acid was divided into DNA and DNA, and its basic units were respectively, DNA and DNA. 4. Identification of reducing sugar, fat, protein, and DNA in biological tissues: Use specific reagents for identification. For example, Fehling's reagent can identify reducing sugar and produce brick-red precipitations; Sultan III dye solution can identify fat and produce orange color, etc. 5. The characteristic of the membrane was that it was selectively pervious, allowing certain substances to pass through while preventing other substances from passing through. 6. The cell membrane's substance exchange function: The cell membrane can carry out substance exchange through free dispersion, assisted dispersion, active transportation, and other methods. 7. The similarities between mitochondria and plastids were that they both had a double-layered membrane structure, were related to energy conversion, and contained a small amount of DNA. 8. The comparison of eukaryote organelle: Different organelle had differences in structure and function. For example, the ER was the synthesis, processing, and transportation channel of protein and other molecular substances; the Golgi apparatus mainly processed, classified, and packaged the protein from the ER. 9. During mitosis, the changes of nuclear DNA, the nuclei of the nuclei, and the nuclei of the nuclei were as follows: during the interphase, DNA replication and the synthesis of related protein were carried out, and the DNA content was doubled; during the prophase of mitosis, the nuclei of the nuclei appeared, and at the anaphase, the nuclei of the nuclei split, and the sister Chromatids separated. 10. The source of ATP-in the body: It is mainly produced by cell breathing (both oxygen and oxygen free breathing) and photosynthesis. 11. [The destination of the ATP-binding in the body: It is used for various life activities of cells, such as muscle contraction and material synthesis.] 12. The comparison between light reaction and dark reaction in photosynthesis: the light reaction occurs on the thylakoid membrane of the plastids, producing oxygen, bound bound 13. The relationship between light energy utilization rate and photosynthesis efficiency: Light energy utilization rate refers to the ratio of the energy contained in the organic matter accumulated by the plant's photosynthesis to the sunlight energy that shines on the ground; photosynthesis efficiency refers to the ratio of the energy contained in the organic matter produced by green plants through photosynthesis to the light energy absorbed during photosynthesis. 14. The relationship between the external factors that affect photosynthesis and the improvement of light energy utilization: The external factors include light intensity, temperature, carbon dioxide concentration, etc., and appropriately increasing the value of these factors can improve the light energy utilization. 15. The metabolism of the three major nutrients in humans and animals: sugar, fat, and protein can be synthesized and decomposed in the body, and they can be converted to each other. 16. The comparison between the two types of breathing: Aerobic breathing produces a large amount of energy and requires oxygen to participate. The reaction site is mainly the mitochondria. The anoxia-less breathing produces a small amount of energy and does not require oxygen. The reaction site is the cellular matrix. In addition, there were also knowledge points about cell structure and function, gene expression, genetic laws, biological evolution, ecological systems, etc., such as cell membrane system, gene translation and translation process, Mendel's law of inheritance, modern biological evolution theory, etc.(Genetic frequency changes, isolation and speciation, etc.), the components of the ecosystem (producers, consumers, disposers, non-biological substances and energy), energy flow (one-way flow, step-by-step reduction), material circulation, and many other topics. These knowledge points were all important parts of high school biology learning, but due to space constraints, it was difficult to list all 300. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to analyze the summary of primary school mathematics knowledge
The analysis of primary school mathematics knowledge points can be summarized from the following aspects: ** I. Arrange by grade ** 1. ** Year 1 ** - The key was to understand numbers and perform simple addition and substitution operations. Among them, abdication was difficult. Although some children had already been exposed to counting and simple operations in kindergarten, abdication still troubled many children. Even in the fourth grade, there might be slow calculations and high error rates. - The learning method was mainly guided and standardized. One could carry out addition and deduction training through life scenes such as shopping in the supermarket and recording the prices of goods. Every day, one would do oral arithmetic questions and check the accuracy rate at time. Parents who were interested could also summarize the error-prone areas of their children and carry out targeted supplementary exercises. 2. ** Second Grade ** - Calculation was the main focus of learning, especially multiplication and division. It was also important to calculate addition within 100. To master the table, not only did one have to memorize it, but one also had to know the source of the numbers. - When learning multiplication, one could not just memorize it in order. Special numbers should be paid attention to. Children who had the ability to learn could gradually learn the big nine-nine multiplication table. 3. ** Year 3 ** - You need to learn the law of multiplication and exchange, grasp the calculation of geometric area and perimeter, the amount of time and units, the calculation of distance, the law of distribution, and the knowledge of decimals. 4. ** Fourth grade ** - It involved the calculation of natural numbers, prime factors, echelon symmetries, and decimals. 5. ** Fifth Grade ** - The key points were the multiplication and division of decimals, algebra equations and their average, comparison of size transformation, and the area and volume of graphs. 6. ** Sixth grade ** - He had to master the knowledge of proportional percentage probability, circular fan, cylinder, and cone. At the same time, he had to remember the area and volume formulas of the triangle, square, rectangular, paralleled quadrilateral, echelon, cuboid, cube, circle, cylinder, cone, and other graphs. He also had to memorize the formulas of the calculation rules of the fraction and the calculation laws of the arithmetic. ** 2. Combing by Knowledge Section ** 1. ** Calculation ** - From simple addition and multiplication (Year 1), to multiplication and division (Year 2), to the calculation of decimals (Year 4 and Year 5), the difficulty gradually increased. In the multiplication operation, the nine-nine multiplication table was the foundation. The memorization method and the deep understanding of multiplication had a great impact on the subsequent calculation ability. 2. ** Geometry-related knowledge ** - Starting from the basic geometry of the second grade, to the calculation of the geometric area and perimeter of the third grade, to the calculation of the area and volume of the figure in the fifth grade, and the knowledge of the circular fan cylinder and cone in the sixth grade, the geometry knowledge gradually became more complicated. 3. ** Algebra Knowledge ** - From the fifth grade onwards, he would be involved in the knowledge of algebra equations. From the concept of one-dimensional equations, examples, and calculations to the use of equations to solve practical problems, this was the development of elementary mathematics algebra knowledge. ** 3. Arrange according to the connections between the knowledge points ** 1. The laws of operation, such as the commutative law of addition, the association law, the commutative law of multiplication, the association law, the distribution law, etc., were important laws that ran through the calculation section. They were reflected in the calculation studies of different grades. For example, they were often used in simple calculations and mixed operations. 2. The addition, multiplication, and division of scores were related to each other, and there was also a connection between scores and the operations of numbers and decimals. For example, the four mixed operations would involve different types of numbers at the same time. 3. In the geometry part, there was a certain derivation relationship between the area and volume formulas of different shapes. For example, the derivation of the volume formula of a cylinder was related to the volume formula of a cuboid. They were both based on the idea of multiplying the base area by the height. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A summary of the knowledge of infectious diseases in the first grade of primary school
Due to their weak immunity and the dense population on campus, first-grade primary school students were prone to infectious diseases, which would seriously affect their health. Common infectious diseases in primary schools included the flu. An infectious disease is caused by a pathogen and can spread from person to person. The measures to prevent infectious diseases in the first grade of primary school are as follows: 1. ** Personal hygiene **: wash your hands before eating, after using the toilet, and after coming into contact with public places; cultivate good personal hygiene habits, maintain the hygiene of the study and living places, clean up the garbage in time, change clothes frequently, and dry the bedding frequently; do not spit or sneeze casually. 2. ** Food and rest **: Eat more fruits and vegetables to maintain a balanced diet; do proper physical exercise every day such as running, skipping rope, etc.; arrange a reasonable rest time to ensure a regular life, ensure adequate sleep, not over-fatigue, prevent colds, and prevent the decline of immune system. 3. ** In terms of environmental hygiene **: Open the windows at regular intervals every day to maintain indoor air flow; regularly check the hygiene of every corner of the campus; formulate and implement a strict disinfection system and disinfect it regularly; strengthen the management of garbage classification. 4. ** Medical Awareness **: If you have a fever or other discomfort, seek medical advice immediately, wear a mask, and wash your hands when you reach home to avoid cross-infection. 5. ** In terms of preventive inoculations **: Carry out preventive inoculations in a timely manner to improve immunity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the summary of primary school epidemic education knowledge
The contents of primary school epidemic education can be summarized from the following aspects: ** 1. Basic knowledge of infectious diseases ** 1. ** Covid-19 related ** - Covid-19 is a disease caused by coronaviruses. People are generally susceptible to it, including those with low immune function and normal people. It is related to the amount of bacteria exposed. People with poor immune function (such as the elderly, pregnant women, patients with liver and kidney abnormalities or chronic diseases) may be more serious after infection. The main routes of transmission were droplet transmission, contact transmission (hand pollution caused self-contact), and possible airborne transmission. The routes of transmission through the airborne and digestive tract had yet to be determined. - In addition to Covid-19, there were six other crown viruses that were known to infect humans. Covid-19 did not show the terrible characteristics of SARS. It is sensitive to heat. At 56 ° C for 30 minutes, ether, 75% alcohol, chloride-containing disinfectant, peracetic acid, chloride-containing disinfectant, and other fatty liquids can effectively inactivate the bacteria, but the chloride-containing disinfectant cannot effectively inactivate the bacteria. 2. ** Norovirus related ** - Norovirus-infected diarrhea occurred throughout the year, and the season of high occurrence was from November to April of the following year. The incubation period ranged from 24 to 48 hours, with the shortest being 12 hours and the longest being 72 hours. - The main symptoms were nausea, vomiting, abdominal pain, diarrhea, abdominal spasms, and other symptoms of gastroenteritis, as well as headache, fever, chills, muscle pain, and other symptoms of poisoning. It was a self-limited disease, without specific drugs and vaccine. It was mainly based on symptom or supportive treatment, and people who were prone to dehydration needed special attention. - The main route of transmission was the faecal-oral route, such as direct contact with the patient's vomit or excrement, contact with objects touched or used by the patient, the smog produced by vomit, contact with contaminated food or water. ** II. Protective measures ** 1. ** In terms of managing the source of infection ** - For infectious diseases (such as the new crown), the reporting system should be strictly implemented. People with infectious diseases should be isolated and treated. The people carrying infectious diseases should be isolated, educated, treated, quarantine and epidemic prevention, and the infected animals should be dealt with. 2. ** In terms of cutting off the transmission route ** - For Covid-19, in public transportation, elevators, shopping malls and other crowded places, we must adhere to the "epidemic prevention three-piece set"(wearing masks, maintaining social distance, and paying attention to personal hygiene). Wearing masks must be worn correctly and changed in time and regularly. Do not take off masks when people are crowded or talking to people. Try to reduce going to crowded places. When returning home, wash your hands and disinfect them frequently. - For Norovirus, one should pay attention to not drinking raw water, drinking boiled water or qualified barreled water, eating raw fruits and washing them, and eating oyster and other seafood after heating and cooking. If there are symptoms of diarrhea and vomiting, use your own utensils and daily necessities, strengthen hand washing, try not to have close contact with family members, do not make food, and do not take care of the elderly and infants. During the illness, disinfect diarrhea or vomit with chloride-containing preparations, and boil food utensils for 30 minutes to disinfect. 3. ** Protecting vulnerable people ** - Non-specific prevention includes improving nutrition (such as balancing diet, ensuring adequate intake of grains, fruits, vegetables, and protein, eating cooked meat and eggs, etc.), strengthening exercise, strengthening physical fitness, improving immunity, etc. - The specific prevention is based on the vaccine (for example, people over the age of 3 years old who are not contraindicated should be "accepted"). Primary school students should pay attention to personal hygiene habits, wash their hands frequently (wash hands with hand sanitizer or soap or running water before meals and after going home), strengthen physical exercise, ensure adequate sleep, and not be picky with food to enhance their immunity; If there are related symptoms (such as nausea, vomiting, diarrhea and other symptoms of Norovirus infection), they should be isolated at home and not enter school with illness. ** 3. School and Family Cooperation in Epidemic Control ** 1. ** School requirements ** - One week before returning to school, teachers and students should do a good job of health monitoring. At home, measure body temperature every day and observe the clinical symptoms related to the infection of the new crown. In case of fever, dry cough, fatigue, sore throat and other symptoms, they should be tested for protein or nuclear acid.
