The answer to a math problem with a big contrast
Take the college entrance examination mathematics questions as an example, there was a huge contrast in the difficulty evaluation. For the 2024 college entrance exam math questions, some examinees felt that it was very simple and even felt that three years of learning had been in vain, while some examinees scored the lowest marks in history. This was because the difficulty of the questions largely depended on the examinee's personal ability and the subjective judgment of the corresponding strength. From the perspective of solving problems, different types of math problems had different solutions. For example, when the area of a triangle in a square could not be solved directly by the triangle area formula, area conversion could be considered. For the problem of the difference in times, one could use a drawing to help understand the relationship between the numbers. For example, if it was originally a small number, it would become a larger number after adding a 0 at the end. The two were 10 times. One could draw a small triangle to represent the original number, and 10 triangle to represent the changed number. The solution could be based on the difference in numbers and the relationship between the numbers. For some reverse thinking questions, such as finding the minimum number of people who can do four of the four items, you can first find the maximum number of people who can't do at least one of the items, and then use the total number of people to subtract the number to get the result. For a question where the multiplication of three consecutive natural numbers equals a given number, you can first decompose the given number into prime factors and then combine them into three consecutive natural numbers. Different people had different feelings about the difficulty of math problems. When solving a problem, one needed to use an appropriate method to solve it according to the type of problem and the known conditions. Read more exciting novels for free
What is a story problem in math?

Fourth grade math dice problem
Dice was a cube. The common six-sided dice had one to six numbers on it, and the number on the opposite side must be seven. China dice were used to paint one and four red. In the fourth grade mathematics questions about dice, there were questions such as calculating the size of the sum of the numbers of two dice facing up to determine whether the game was fair. For example, if the sum of the numbers on the two dice was greater than or equal to 7, Xiaoxiao would win, and if the sum was less than 7, Naughty would win. It might also involve the calculation of the sum of the numbers on the hidden side of the die, which needed to be calculated according to the numerical characteristics of the die. At the same time, the number of points rolled by the die was a random number from 1 to 6. The results of each roll were independent of each other. This also provided the foundation for some preliminary ideas about probability and statistics. In the teaching, the students would be able to master the basic shape, number, and throwing calculation of the dice through the model of the dice. They would also be able to cultivate hand-eye coordination and spatial sense. There would also be dice calculation games to deepen the students 'understanding of the dice points and calculation.

Elementary math problem solving tricks and answers
Here are some tips for solving elementary math problems: ** Arithmetic class of the first and fourth rules ** 1. ** Clear the relationship between the four operations ** - This was the key to solving the four arithmetic problems. For example, in a division algorithm, the relationship between the dividends, the divisions, the quotient, and the remainder must be clear (dividends = divisions x quotient + remainder). If you encounter a problem like "() div5 = 6... 4", you must be able to determine that the dividends in the parenthesis represent the dividends. According to the relationship, the dividends are calculated as 5×6 + 4=34. ** 2. Problem Solvers ** 1. ** Confirm the quantity in the question and the quantity required ** - Seeking the price, the total amount of work, the amount of each portion, and the distance were common test points. For example, in the itinerary problem, one had to be clear about whether the time, speed, or distance given in the question was time, speed, or distance. Then, one had to solve the question according to the relationship of "speed x time = distance,""distance/speed = time,""distance/time = speed," and so on. For example, if Xiao Ming walked 10 minutes to school every day and walked 50 meters per minute, 10 minutes was time and 50 meters was speed. To find the distance from Xiao Ming's home to school (distance), 50×10 = 500 meters. - When it came to money, one had to distinguish between the original price, current price, cost price, selling price, and other concepts. Combined with the reality of life, one had to find an equivalent relationship to solve it. 2. ** Practically ** - Some abstract mathematical concepts could be understood through practical operations. For example, in the first grade, the students could understand the advance rate of yuan, angle and minute by strengthening the practical operation; in the middle grade, the practical operation could reduce the confusion of concepts when teaching circumference and area; in the senior grade, the use of Quissonite wood strips or counting boards to guide the operation could reduce the difficulty of learning. 3. ** Seeking answers from everyday life ** - To connect mathematics knowledge with daily life. For example, in the "direction identification" teaching, create a scene of direction identification in daily life, introduce new lessons, let students solve practical problems in the simulated street, explore new directions, and then use the knowledge they have learned to solve the direction problems in life, such as judging the direction of the surrounding children, drawing the zoo map, etc. 4. ** Simply simplify the problem and find conditions from the problem ** - Experience and understand mathematics in real life situations. For example, according to the situation of the teacher's daughter drinking milk, she would propose a mathematical problem and solve it according to the amount of milk she drank each time, so as to understand the knowledge of "moving more to make up for less." - Independent thinking, independent exploration, and cooperation and communication are encouraged. For example, in the teaching of finding the average, after the teacher raised the question, the students would discuss it in small groups to find the relationship between the number of the applied questions. - The content of the lessons should come from daily life, using data and questions from daily life, such as average scores, average height, seasonal water consumption, etc., to make students feel that mathematics was right beside them. 5. ** Cultivate application awareness and problem solving skills ** - Using his life experience, he could apply the mathematics knowledge he had learned to his daily life. For example, in the car rental problem, 27 people could take a car. One car could take 8 people, and the other car could take 4 people. First, a variety of car rental plans were given, and then according to the rent of different cars (the first car was 300 yuan/day, the second car was 200 yuan/day), which plan cost the least. 6. ** Searching for patterns from problems ** - For some numbers, such as 50, 98, 38, 10, and 51, the size relationship between them was described in terms of larger, smaller, much larger, and much smaller, and represented by " He could also use some daily estimations to understand the rules, such as how thick 1200 pieces of paper were, how many classes 1200 students could form, how long 1200 steps were, and so on. ** 3. Mathematical Olympiad category ** 1. ** The problem of crossing the bridge by train and sailing by water ** - He had to grasp the specific relationship of such problems. For example, when a train crossed a bridge, the length of the train itself had to be taken into account; when sailing on water, the speed in the water = ship speed + water speed, and the speed against the water = ship speed-water speed. 2. ** Concentration problem ** - He had to distinguish the concepts of solute, solution, and solution. Solute is something that is put into a liquid (it may be a solid or a liquid), the solution is water (liquid), and the solution is a mixture of solute and the solution. ** 4. Solution Skills ** 1. ** Drawing Method ** - For some sum and difference problems, drawing could make the abstract problem graphic and easy to understand. For example, the sum of two numbers is 81, and the difference between the two numbers is 19. You can draw a line diagram and represent the decimals and large numbers with line segments. According to the difference being 19 and the sum being 81, you can first find the decimals as (81 - 19) div2 = 31 and the large numbers as 31+19 = 50. 2. ** Techniques for solving equations ** - When solving an equation, such as the equation "80-(x + 2) div3 =76", the complex parts could be regarded as a whole. First, he calculated 80 minus 76, which gave (x + 2) div3 = 4. Then, he calculated x + 2 = 12, which gave x = 10. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
