Title: 11Choose5mathQuestionsAnswerKey3rd
Introduction: In this article, we will cover a series of carefully selected math problems that apply to students in the third grade of primary school. We will select 5 out of 11 math problems for detailed solutions, with an explanation of the answers to help students better understand and master math knowledge.
Question 1: Xiao Ming has 12 pencils, he uses half of them, how many pencils do he have left?
Answer: Xiao Ming has 12 pencils, and half of them are used to use 6 pencils, so he still has 6 pencils left.
Question 2: Xiaohong’s mother’s age is more than 4 times Xiaohong’s age, if Xiaohong’s age is A, then how old is her mother’s age?
Answer: Xiaohong’s mother is more than 4 times the age of Xiaohong, which can be expressed as 4A years old. Therefore, if Xiaohong’s age is A, her mother’s age is 4A.
Question 3: When Xiao Liang was calculating a subtraction problem, he mistook the subtraction for the addition number, so how much bigger is the answer he came up with? Suppose the original difference is negative.
Answer: Xiao Liang mistook the subtraction for an addition when calculating, so his calculation process has one more subtraction than the actual process. Assuming that the original difference is negative, then his answer will be twice the size of this minus that is greater than the actual answer. As a result, his answer is twice the size of the error section than the actual answer.
Question 4: Xiao Ming and Xiao Hong went to buy candy, Xiao Ming bought three bags of candy and spent a total of 18 yuan, each bag of candy cost 3 yuan less than Xiao Hong, how much did Xiao Hong spend?
Answer: Let’s say that Xiao Hong buys three bags of candy, then the price of the candy should be one-third of the sum of the money she bought plus the money she paid less (that is, half of what he spent), and then three times the calculated number plus the difference of the total cost. Knowing that Xiao Ming’s fee is the total amount of half price plus the value of half price and the total amount minus nine yuan is eighteen yuan, we can calculate that Xiao Hong’s purchase price should be fifteen yuan. Therefore, Xiaohong spent fifteen yuan on candy. Through this approach, we can help students understand the concepts of relative price and total price. This technique helps in their application in everyday life. They can easily solve problems about price comparisons and purchase plans. This question also relates to the application of proportional and arithmetic operations. By solving these kinds of problems, students can exercise their math skills and boost their self-confidence. The process of problem resolution is a demonstration of rigorous logical reasoning and flexible thinking. Each student can use this process to improve the overall development of the ability to understand and master mathematical knowledge and improve the development of thinking skills. Therefore, students should carefully study and understand the process and method of problem analysis. Through continuous practice and challenge, self-challenge, problem-solving methods, learning skills and techniques, constantly improve your ability and confidence, and further enhance your interest in mathematics and awareness of the value of mathematics! Encourage them to work hard to challenge more difficult problems to get better opportunities for growth and progress, and experience a rich and interesting exploration process, and experience the fun of exploring mathematics! Enjoy the joy of successful learning! The process of solving this problem not only involves basic arithmetic operations, but also involves the exercise and development of logical reasoning and problem-solving skills, so students should take this problem seriously and strive to understand and master its solution methods and skills to improve their mathematical ability and self-confidence, I believe you will be able to successfully solve more mathematical problems!
