There were some channels that could provide video explanations of elementary school students 'basic mathematics training questions. For example, there were video explanations for thinking questions in grades 1 to 6, which could be used to improve their ability to solve problems, including explanations on various types of questions such as restoration questions. There was also training content for the basic knowledge of mathematics in the new textbook for grade 6. Although it was not explicitly mentioned that it was a video explanation, it could be used as basic training materials. In addition, there were also video guides that specifically sorted out problems related to the division of two numbers, such as finding two numbers when the quotient of two numbers is 5, the remainder is 2, and the sum of two numbers is 80.

Here are some ways to get video guides for elementary school students: 1. ** supplementary teaching materials with videos **: supplementary teaching materials such as " notes of the top student in the experimental class " were synchronized with the teaching materials and had video explanations. These videos would include pre-class self-revision content, detailed notes on the text, including central ideas, key annotations, mind maps, etc. After class, there would be knowledge of words, writing, key words, and answers to exercises. There would also be outline materials and model essays for oral communication exercises. The Chinese section had unit knowledge induction, and even reading comprehension answer templates, which could fully assist primary school students in learning the text. 2. ** Special text explanation mini-class **: For example, there was a synchronized mini-class video explanation for the first volume of the fifth grade Chinese language book,"Osmanthus Rain". There were also a series of videos for the second volume of the fifth grade Chinese language book, such as "Pyramid","Grandfather's Garden", etc., from word learning to text explanation. These micro-class videos could explain specific texts in detail. 3. ** Pre-reading materials for teaching materials **: For example, some of the teaching materials with the five-step pre-reading method include the original text, central ideas, paragraph analysis, reading aloud, new words after class, difficult words, detailed explanations of after-class exercises, key shorthand, and mind map sorting. This helps primary school students better understand the text when preparing and reviewing the text. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

1. ** Writing and division ** - ** Rows of steps **: - First write "factory"(division sign), then write the dividends inside "factory", and write the divisions on the left side of "factory". - First quotient: write the quotient above the dividends; Second multiply: write the product of the quotient multiplied by the dividends below the dividends; Third subtract: draw a horizontal line and write the difference between the product of the quotient multiplied by the dividends and the dividends. When calculating vertically, the same digits must be aligned, and the remainder must be smaller than the dividends. - ** example **: - For example, calculating 42 div2. First, write 42 inside the division sign, and then write 2 outside the division sign. Starting from the high digits, 4 in the tenth digit represented four tens. Dividing four tens by two would yield two twens. Write the "2" above the tenth digit corresponding to the division sign. Subtracting 40 points would yield 0 (the 0 here could be omitted). Then, he placed the 2 on the single digit and continued to divide it. Dividing the 2 by 2 was 1, and there was no remaining (the 0 here could not be omitted, indicating that it was just divided). - Another example was calculating 52/2. 50 could be divided into two 20s (two 20s were four tens). Write the 2 above the division sign and the 4 below the ten digits. Subtracting the 4 tens from the 5 tens left one ten. If the two ones in the unit were combined with the remaining ten, it would be 12. Dividing 12 by 2 would be 2 times 6 ones, which was just enough. 2. ** Checking the calculation of division by pen (when there is no remainder)**: You can use quotient and division to check. If the product was exactly the same as the dividends, then the quotient was correct. Otherwise, it was wrong and needed to be re-calculated. 3. ** Two-digit number divided by one-digit number (every digit of the dividends can be divided)**: - Divide the two-digit number into a whole ten and a one-digit number, divide the whole ten and the one-digit number by a one-digit number, and then add the quotient of the two divisions. For example, if you calculate 12 div3, you can think of it as 10 div3 = 3 + 1, 2 div3 quotient 0 + 2, and then add the quotient to get 4. - He could also memorize the calculation method through a doggerel formula."First round and then divide by zero. Don't forget the composition of the number. At the end, remove the zero to slim down. Divide within the table." You could also use the method of removing zeros and then use the table to perform a quick calculation. For example, 120 div3, first calculate 12 div3 = 4, and then add the same number of zeros at the end of 4 as the dividends (Here, the dividends 120 have one zero, so the result is 40). However, when dividing the first two numbers, if the end is zero, the number of zeros in the quotient is one less than the number of zeros in the dividends. 4. ** In a division formula with a remainder (such as ( ) div7 = 6... Find the maximum value of the dividends in ( ): - According to the principle of the remainder being smaller than the division, when the division is 7, the largest remainder is 6 and the smallest is 1. - Divider = quotient x division + remainder, so when the remainder is at most 6, the dividends are the largest, 6×7+6 = 48; when the remainder is at least 1, the dividends are the smallest, 6×7 + 1=43.

There were indeed some seemingly simple but confusing questions in primary school mathematics. For example, the problem of repairing bricks. The existence of half a brick might confuse the child. It was necessary to observe the arrangement of the bricks, first calculate the number of bricks in a complete row, then calculate the number of bricks in the empty row, and then use the number of bricks needed in each row to subtract the number of bricks in the empty row. Finally, the number of bricks in each row was added to get the total number of missing bricks. The question of knowing the direction was a test for the spatial thinking ability of the third grade children. When the spatial imagination ability was limited, they could use children's songs to remember the method of direction judgment. The process of solving equations using the properties of equations was long and tedious when they first started learning. Although the shifting method was short, it was easy to make mistakes. There were also calculation problems that included a variety of situations, such as the first grade addition and substitution calculation method, the memorization of multiplication pithy formula, and the proficiency in three-digit multiplication of one-digit numbers, two-digit divisions, decimals, and simple calculations. In addition, questions like A multiplied by B equals 16, A multiplied by A equals 8, and B multiplied by B needed to be solved by finding the relationship between A and B. There were also controversial questions about the concept of repeating decimals, and different people would get different answers. These questions might be difficult for primary school students, but for graduate students, due to their long-term exposure to advanced mathematics knowledge, when faced with these questions with unique elementary school logic, they might also be difficult to answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The following is a tutorial for primary school students: ** 1. Prepare the materials ** White mirror-like Xuan paper (similar to paper), marker pen (watercolor pen can also be used). ** 2. Design a separate pattern (pattern unit)** 1. You can choose the elements you like, such as flowers (the various flower paintings in the reference materials), simple geometric shapes, and so on. If you were drawing flowers, like hydrangea, you could first use a mechanical pencil to draw two big and small circles as the outer outline of the flower. Then, you could set three points in the small circle as the center of the three main leaves. Then, you could outline the size of the petals. After positioning the main petals, you could add other petals. Sunflowers could first draw two big and small circles and straight branches, then divide the circle evenly into eight halves and draw the petals according to the auxiliary lines, and then add other petals and leaves. 2. When designing geometric shapes, you can draw simple circles, squares, and triangulations. You can also combine these shapes or add some decorative lines, such as drawing diagonal lines and wavy lines in the square. ** 3. Form a continuous pattern in four directions (forming a floral pattern)** 1. He copied and pasted the individual patterns and arranged them according to a certain bone pattern to form a complete pattern. For example, they could be arranged neatly up, down, left, and right (similar to a square arrangement), or rotated at a certain angle, such as rotating the individual patterns by 90 degrees every other time. 2. Extending the complete pattern in four directions formed the pattern of the floral cloth. ** 4. Perfect the image (option)** 1. If you want to show the floral cloth in a certain scene, like the scene in Wuzhen (refer to the combination of Wuzhen blue floral cloth and houses), you can use a needle pen or a thinner pen to draw some simple architectural outlines behind the floral cloth, such as the shape of the house, tiles, and other details. Then use different colors of pens (such as dark gray and light gray marker pen) to show different parts of the house. 2. You could also add some shadows or highlights to the floral cloth to make the picture more three-dimensional. For example, you could use a dark marker to draw some shadows where the floral cloth pattern overlapped or turned. The novel "Flower in the Heart" is equally exciting.

The following are some elementary school math problem solving techniques: 1. Drawing Strategy: Translate the words of a difficult problem into a picture. It can quickly sort out your thoughts and find a solution. In the process of solving a problem, by drawing a diagram related to the meaning of the problem, the diagram was used to help reasoning and thinking. This was especially common when solving problems such as geometry, proportions, or scores. 2. ** Transformation Strategy **: Transform a complex problem into a simple problem, and turn an unknown problem into a known problem. This is one of the common methods used to solve problems in primary school mathematics. 3. ** List Strategy (Enumeration Strategy)**: List the condition information of the problem in the form of a table. This makes it easy to find the problem and analyze the quantitative relationship, thereby eliminating the interference of non-mathematical information. At the same time, it also helps to find a solution to the problem. When using it, one must pay attention to not repeating or missing anything. 4. ** Enumeration Strategy **: When solving some special problems that cannot be calculated, it can list all possible situations of the research object, so that the problem can be solved more easily. When listing, you have to think in an orderly manner to ensure that you don't miss anything. 5. ** Substitution Strategy **: Used to solve the problem of the relationship between several quantities and the total quantity. By using this strategy, the relationship between two quantities could be simplified into one, which would help to solve the problem. 6. ** Comparing Method **: According to the meaning of the mathematics question, compare the meaning and essence of concepts, properties, laws, rules, formulas, terms, and terms. Relying on the understanding, memory, recognition, reproduction, and transfer of mathematical knowledge to solve the question. This would help train the child to have a correct understanding of mathematics knowledge, a firm memory, and accurate identification. 7. ** Comparisons **: By comparing the similarities and differences of mathematical conditions and problems, you can study the reasons for the similarities and differences and find a solution to the problem. When using it, you need to pay attention to the completeness of the comparison, find the connection and difference, compare under the same relationship, and grasp the main content to compare carefully. 8. Formula Method: Use laws, formulas, rules, and rules to solve problems, reflecting deductive thinking from the general to the special. However, it was necessary to ensure that the child had a correct and profound understanding of formulas, laws, rules, and rules, and could use them accurately. 9. ** Analysis Method **: To break down the whole into parts, to break down complex things into various parts or elements, and to study and derive these parts or elements. The idea was to start from the problem to be solved, choose the two conditions needed correctly, and deduce them one by one until the problem was solved, which was "tracing the cause from the effect." 10. ** Holistic approach **: For some calculations, when a certain part cannot be calculated directly, this part can be regarded as a whole and solved step by step. For example, when solving an equation, if there were multiple calculation steps on one side of the equal sign and a certain part could not be calculated, one could first treat this part as a whole to solve it. 11. ** Using Aptitudes **: When you encounter complex calculation problems, you can use approximate numbers to help with quick calculations. 12. ** logical reasoning method **: When solving some reasoning or logic questions, use logical reasoning to get the correct answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The primary school mathematics basic skills test had the following characteristics: * * 1. Knowledge coverage ** 1. * * System ** - The exam content and questions were continuous and stable. The questions in each grade were relatively uniform, roughly consisting of "writing","fill in the blanks","choice","calculation"(2 - 3 types),"practical operation questions"(testing geometric knowledge), and "solving problems"(3 - 5 small questions). However, due to the differences in the contents of each volume of teaching materials, there were various ways to present the questions in the field of geometry, such as practical operation, dividing the figures, doing the questions according to the requirements, etc. The examination content was mainly based on the teaching materials, and the difficulty level was subject to the curriculum standard. 2. * * Comprehensiveness ** - It was based on the teaching materials and focused on the examination of basic knowledge and basic skills. The contents of each grade's questions were comprehensive, covering the basic knowledge, basic skills, common mathematical ideas, and mathematical methods in the teaching materials. The key points were prominent, the questions were not strange, and the solutions were conventional. It was easy for students to get started. * * 2. Ability Test ** 1. * * procedurally ** - Some questions focused on the mathematical evaluation of knowledge, reflecting the process of learning knowledge. For example, in the problem solving questions of different grades, students were required to draw small sticks, write reasons, answer vertically, write plans, and calculate the rent to show the calculation process or solution ideas. This reflected that not only did they have to know the truth, but they also had to know the reason. 2. * * Open ** - As the new curriculum reform deepened, the number of open questions increased. Grades 1 - 5 (excluding Grade 3) had content that allowed students to raise questions and solve them themselves. This type of test questions gave more space in terms of question type design, content selection, scoring standards, etc. The conditions, requirements, or conclusions were uncertain, and the answers were diverse and not unique. It could make students 'thinking more open and active. * * 3. Questions reflected by the students 'answers ** 1. * * Basic knowledge is not solid enough ** - From the feedback of each grade's paper, the students lost more marks in filling in the blanks and choosing the questions, reflecting that the teachers usually did not have strict requirements for the students to master the basic knowledge, and the checks were not detailed enough. 2. * * Calculation problem ** - Calculating was an important part of the test. The students lost marks mainly because they were not serious enough. For example, in the calculation questions of the fifth grade, some students did the questions blindly without observing the characteristics of the questions, and those that should be simplified were not simplified. In solving equations and checking the questions, because the checking method was not closely related to the content of this period, the students forgot more seriously. 3. * * Some questions are too challenging ** - Some of the questions, such as some of the first-year problem solving questions, exceeded the standard content of the curriculum, causing difficulties for students to answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
