What content should I pay attention to in the elementary school Olympiad logical reasoning questions?
To answer the elementary school Mathematical Olympiad logical reasoning questions, one usually had to pay attention to the following aspects: 1. Choosing the right breakthrough point: When analyzing, combine several conditions to make a judgment, and find the key and easy to start reasoning from the multiple conditions of the question. 2. Constantly eliminating: According to the conditions in the question, in the process of reasoning, constantly eliminate the impossible situation, narrow the scope, and then come to the required conclusion. 3. "Reasonably Assuming: Make assumptions about possible situations and then reason based on the conditions. If the conclusion is not contradictory to the conditions, it means that the assumption is correct. 4. [Tools: When encountering complex reasoning problems, you can use charts (such as lists) to analyze them to make the relationships more intuitive and clear. You can also use methods such as hypothesis analysis, comparison analysis, and number theory analysis.] 5. Carefully analyze the relationship between the conditions, including the relationship between the character and the occupation, the size of the number, etc. When it comes to the occupation and age of multiple characters, you have to clarify the relationship between each condition in order to make accurate deductions.

Elementary school students 'reasoning questions
Elementary school students 'reasoning questions mainly included the following: ** 1. Comparisons ** 1. ** Speed Comparisons ** - For example, a black rabbit, a white rabbit, and a gray rabbit were racing. The black rabbit said,"I'm not the fastest, but I'm faster than the white rabbit." This type of question needed to infer who was the fastest and who was the slowest based on the relative speed relationship given. 2. ** Age comparison ** - For example, three sentences were given to the three children's ages, such as " Fangfang is three years older than Yangyang; Yanyan is one year younger than Fangfang; Yanyan is two years older than Yangyang." The students were asked to deduce who was the oldest and who was the youngest. 3. ** Comparing heights ** - Given that A said "I am taller than B", B said "I am shorter than C", and C said "I am taller than A", let's determine the tallest and shortest people. 4. ** Weight comparison ** - For example," A is heavier than B, B is lighter than C, C is heavier than A, and D is the heaviest ", the order of weight of the four children was required. 5. ** Class Number Comparisons ** - For the three classes of Guangming kindergarten, according to the conditions of " the middle class has fewer students than the small class, the middle class has fewer students than the large class, and the large class has more students than the small class ", which class has the least number of students and which class has the most students. ** 2. Identity Reasoning ** 1. ** Surname Reasoning ** - Give three sentences about the surnames of children A, B, and C, such as " A is not surnamed Zhang; Huang is not C; A and B are listening to the child surnamed Li sing ", and then infer the surnames of children A, B, and C. 2. ** Profession Reasoning ** - For example, Xiao Li, Xiao Wang, and Xiao Zhang were lawyers, doctors, and engineers respectively. They gave conditions such as " Xiao Zhang is older than the engineer, Xiao Li is not the same age as the doctor, and the doctor is younger than Xiao Wang " to determine their respective occupations. ** 3. Item allocation reasoning ** - For example, when Teacher Zhang gave each of the red, white, and blue balloons to the three children, according to "Xiao Chun said,'I didn't get a blue balloon.' Xiao Yu said,"I didn't get a white balloon." Little Light said,'I saw Teacher Zhang give the blue and red balloons to the two children on the top.'" To deduce the color of the balloons that each child was assigned. ** 4. Ranking Reasoning ** - For example, if three children, A, B, and C, were running a race, they would know that "the first place was not A, and the second place was not C. B saw that A and C had reached the finish line ahead of him", thus determining the rankings of A, B, and C. These questions helped to cultivate the logical thinking ability of primary school students. The solution method could be used to analyze the relationship between the given conditions, gradually eliminate the possibility, and draw the correct conclusion. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to do the two square questions in the elementary school Olympiad math
There were many ways to solve the question of two squares in the elementary school Mathematical Olympiad. The following were some common situations: ** 1. Area related ** 1. ** Area difference problem ** - If you know the difference in the perimeter of two squares, you can first find the difference in the length of the sides. For example, the difference between the circumference of two squares is 32cm. Since the circumference of a square = 4 x the length of a side, the difference in the length of a side is 32 × 4 = 8cm. If the area difference was known, it could be solved by making an auxiliary line. For example, the shadow part (the area difference part) was cut into several parts, and the area of the special figure (such as a small square) constructed from it was used to calculate the area of the rectangular shape, and then other unknown quantities such as the length of the side were calculated. 2. ** Overlapping Area Problem ** - When two squares overlapped, the area of the shadow (usually the non-overlapping part) needed to be calculated according to the known conditions (such as the length of the side, the length of the line segment of the overlapping part, etc.) through the combination and decomposition of the figures. He might use the area formula of a triangle, a echelon, and other shapes, as well as the idea of equal-area transformation to convert the area of an irregular shape into the area of a regular shape for calculation. ** 2. Edge length related ** 1. ** Proportional relationship of side length ** - If the proportional relationship between the sides of the two squares and other related conditions (such as the sum of the area, the sum of the perimeter, etc.) were given, one could set the side of one of the squares as an unknown number and solve the equation according to the conditions. For example, let the side length of a small square be x, and the side length of a large square be kx (k is a known proportional coefficient). Then, according to the perimeter sum or area sum conditions, the equation is listed to solve the side length. 2. ** The relationship between length of side and line segment ** - When two squares have a specific position relationship and the length of some line segments is given (such as the line segment connecting the two square vertexes, the distance between the two squares, etc.), the Pythagorean theorem or the similarity of geometric figures can be used to establish the relationship between the length of the line and these line segments, thereby solving the length of the line or other related quantities. ** 3. Combination Diagram ** 1. ** Construct a special pattern ** - For example, when calculating the area of the shadow part in the combination of two squares, one could construct a echelon by connecting the diagonal lines, and use the properties of the echelon (such as the equal area of the wings, that is, the area of the two non-adjacent triangle that is divided into four by the diagonal of the echelon is equal) to convert and calculate the area. 2. ** Relationship between the whole and the parts ** - Take the graph composed of two squares as a whole, analyze the relationship between the various parts (such as squares, triangle, echelon, etc.), and calculate the unknown variables such as the area and side length of the whole or part according to the known conditions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Seeking logical reasoning questions!
The logical reasoning questions were as follows: Imagine a small town where everyone is of the same race and everyone has the same characteristics such as height, weight, skin color, etc. However, there was another difference in this town. Everyone in the town had a unique name. Are all the people in this town of the same race? Answer: No. The people in this town might be of the same race or of different races. For example, if the people in the town were all black, then everyone had the same characteristics but they all had a unique name, so they were not of the same race; if the people in the town were all white, then everyone had the same characteristics but they all had a unique name, so they were not of the same race. Therefore, the people in this small town might be of the same race or of different races.
Elementary School Students 'Mathematical Olympiad
There were many ways for elementary school students to calculate Olympiad math: 1. ** Borrowing Number Method **: Borrowing a number from a number, turning it into a whole ten, a whole hundred, or a whole thousand, and finally deducting the borrowed number. For example, if you calculate [9 + 99+999 + 9999], you can convert it to [(10 - 1)+(100 - 1)+(1000 - 1)+(10000 - 1)=10+100 + 1000 + 10000 - 4 = 11106]. 2. ** Choose Base Number **: Find a number that everyone is close to as the base number. For example, if you want to calculate [489+487+483+485+484+486+488], first determine the base number [490], then use [490×7 - 1 - 3 - 7 - 5 - 6 - 4 - 2 = 3430 - 28 = 3402]. 3. ** Transposition Method **: Transposition the position of the numbers in the calculation and change the order of the numbers. For example,[632 - 156 - 232 = 632 - 232 - 156 = 400 - 156 = 244];[128+186+72 - 86 = 128+72+186 - 86=(128 + 72)+(186 - 86)=200 + 100 = 300]. 4. ** Common factor extraction method **: Use the multiplication distribution law to extract the same factor and add and subtract the remaining terms to obtain an integral number. For example,[0.92×1.41 + 0.92×8.59 = 0.92×(1.41 + 8.59)]. 5. ** Borrowing and borrowing method **: Use it when you observe that there are numbers close to 10 or 100 in the formula that are easy to calculate. Pay attention to borrowing and returning. For example, 9999+999+99+9 = 9999+ 1+999 + 1+99+1+9+1 - 4. 6. ** Splitting Method **: In order to split a number into several numbers, you need to master some "good friend" numbers, such as <2> and <5>,<4> and <5>, and do not change the size of the numbers when splitting. For example, 3.2×12.5×25 = 8×0.4×12.5×25 = 8×12.5×0.4×25. 7. ** Association Law of Additions **: Use the rule of "(a + b)+c = a+(b + c)" to change the position of the addend to obtain a simpler operation. For example,[5.76+13.67+4.24+6.33=(5.76 + 4.24)+(13.67 + 6.33)]. 8. ** Combination of splitting method and multiplication distribution law **: When you see numbers that are close to an integral number such as <99>,<101>,<9.8>, you must first consider splitting. For example, 34×9.9 = 34×(10 - 0.1). 9. ** Using the formula method **: - The law of addition: Commutative law (a + b = b + a), Association law ((a + b)+c = a+(b + c)). - Subtraction operation properties: <a-(b + c)= a-b- c>,<a-(b-c)= a-b + c>,<a-b- c = a-c- b>,<(a + b)-c = a-c + b = b-c + a>. - Multiplication (similar to addition): Commutativity, Association, Assignment Rate, A + B, C = ac + Bc, A - B, C = ac -Bc. - The properties of division (similar to substitution) were: <a Mum (b×c)=<a Mum (b× c)>,<a Mum (b × c)=<a Mum (b×c)>,<a Mum (b × c)=> a Mum (b ×c)>,<a Mum (b × c)=> a Mum (b × c)>,<a Mum (a Mum (b)= a Mum (b × c)> c & 10. ** Split term method **: Split term method is to split the terms in the score formula so that the split terms can be offset. The common split term method is to split the number into the sum or difference of two or more numerical units. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Second grade elementary school students pay attention to matters and suggestions
The following is a list of precautions and suggestions for second graders: ** 1. Learning ** 1. ** Language * - Pinyin must be mastered. Remember the pronunciation of the finals, the initial, and the overall syllable. Read the relevant pithy formulas repeatedly. After mastering a single syllable, you will naturally be able to spell it. - Pay attention to the accumulation of literacy. You must be able to read and write the new words in the textbook. You can increase your literacy through reading. When you learn to read, you can combine the meaning of the words and the interesting memory of the glyph. - When doing the ranking questions, those with good language sense could rely on their language sense. Those with poor language sense had to read the text well, because the ranking questions of the lower grades mostly originated from the original text of the textbook. - The simpler the words and sentences, the better. - In terms of reading, stick to reading for 30 minutes every day to cultivate interest in reading. The answers to the reading comprehension of the lower grades are mostly in the text, so try to answer the questions in the original text. - If you start to come into contact with writing, parents can help their children write essays from the "three-paragraph" structure, that is, the beginning, the middle development, and the end. For children who have the ability to learn, they can practice the five elements of early writing (time, place, character, what to do, and result). The second paragraph can guide the child to describe the details and pay attention to the use of connecting words. 2. ** Mathematics ** - First, he had to master the basic knowledge in the textbooks. - Carry out special exercises, such as mental arithmetic, application questions, etc., to improve calculation ability and accumulate experience in solving questions. - After each test, he sorted out the wrong questions and checked for any missing questions. - Read the questions carefully when you do them. You can repeat or draw pictures to help you understand the application questions. 3. ** English * - Persevere in reading the words and texts for 10 minutes every day to cultivate the sense of language. - Try your best to read the text and even memorize it, because the test mostly comes from the original sentence of the text. ** 2. Campus behavior ** 1. Be civilized, speak and act appropriately, use civilized and polite language, and put an end to fighting and foul language. 2. Filial piety to parents, respect for teachers, love for classmates. 3. Wearing the school card in a prominent position on the chest of the campus, entering and leaving the campus to accept the inspection. 4. Respect others, actively cooperate with the work of the school staff, do not arbitrarily alter or tear the blackboard notice. 5. The appearance was in line with the student's identity. The clothes were clean and generous. They did not dye their hair or perm their hair. They did not wear earrings, necklaces, rings, and other accessories. They did not wear slippers to enter the teaching area. 6. Protect public facilities and reject the "desk" culture. 7. Maintain public health, consciously clean the clean area and classroom hygiene, do not spit, throw trash, do not damage flowers and trees, pay attention to personal hygiene. 8. Conserve water and electricity, and put an end to "running water" and "lights". 9. When eating, they should abide by the rules and line up consciously. They should not fight for food or waste food. 10. They should strengthen physical training and carry out civilized sports activities. They should not participate in physical training bare-chested. During lunch break and after evening self-study (if there is), they should not carry out physical activities according to regulations. 11. Don't make noise in the classroom or dormitory during break time. After turning off the lights at night, maintain the discipline of going to bed. 12. Law-abiding, no smoking, no drinking, no gambling. 13. Male and female students interacted normally, and their behavior was civilized and appropriate. ** Model proposal ** Dear second year students, Hello everyone! In our studies and campus life, there are some things that we need to pay special attention to so that we can grow better. Learning is our most important task now. In Chinese learning, Pinyin is the foundation of the foundation. We must learn it well, just like building a house requires a good foundation. Learning how to read is also crucial. It helps us understand the subject and read the books better. In terms of mathematics, we have to learn the textbook knowledge first. Doing more specialized exercises will allow us to calculate quickly and accurately. He had to listen and read more in English to cultivate his sense of the language. In school, we must be the little messengers of civilization. Civilized words and deeds will make our campus even better. Greet your teachers and get along well with your classmates. They had to abide by the rules of the school, such as wearing a school card and taking care of public facilities. They had to maintain hygiene in the classroom and on campus and not throw trash everywhere. I hope everyone will remember these things so that we can have a happy and fulfilling time in the second grade.
