The topic and analysis will be carried out in detail in the following articles, welcome everyone to continue to pay attention and provide valuable feedback, so that we can better meet the needs of students and parents, and then we will analyze several typical questions and their solution ideas and answers in detail for parents and students to use for reference. Arrange the numbers from largest to smallest, please arrange the following numbers in order from largest to smallest (note that the decimal point is also counted as a single digit) Analysis: This question mainly examines students' understanding of the size of numbers and basic sorting ability, and the answer prompts students need to understand the meaning of the decimal point and incorporate it into the sorting process, for example, the number 3.5 should be ranked in a position greater than 3 and less than 4, similar to the arrangement of digital numbers, and the decimal needs to be placed in the correct position (when waiting for the answer, let the children observe and experience this question, and then encourage them to answer and communicate with parents) twoPlease observe the law of a group of numbers and fill in the missing number analysis, this question aims to test the student's observation ability and logical reasoning ability, by observing the given number sequence, find out the law and fill in the missing numbers, for example, the number series may be like this, the first three numbers increase by a number, but in the fourth step decrease, how this happens, how to fill in the situation, students must clarify the logical relationship and change trend between the number series before and after, and then determine the next correct numerical answer according to this point, the answer to the question is actually related to a series of inductive reasoning, encourage children to find more possible answers, so that their thinking can be more active, expand their thinking, and let them benefitInfinity Three, Combined with daily life calculation area and volume and other practical problems, combined with the scene in daily life, let students use the mathematical knowledge they have learned to solve the actual area and volume calculation problems, such as giving the dimensions of the room, let the children calculate its area or calculate the volume of objects, etc., such problems not only test students' computing ability, but also test their ability to understand real life, so that they can realize the practical application value of mathematics in life, so as to better stimulate their interest in learning, the answer reminds students to pay attention to the units in the problem and related calculation formulas, such as paying attention to parameters such as length and width when calculating the area, and paying attention to the three dimensions of length, width and height when calculating the volumeStudents should use the knowledge they have learned to solve problems in combination with the actual situation, and by answering such questions, students can deepen their understanding and application of mathematical knowledge and improve their ability to solve practical problemsbai da. The challenge of comprehensive application problemsComprehensive application problems often involve the comprehensive application of multiple knowledge points, which requires students to comprehensively use the mathematical knowledge they have learned to solve practical problems, such as problems involving proportional fractions, combined with practical application scenarios such as shopping discounts, etc., so that children can calculate, which can not only consolidate their mathematical knowledge, but also allow them to better understand the practical application value of mathematical knowledge (waiting for the typical problems and analysis of comprehensive application problems to be provided later) Through the analysis of the above typical questions, we can find that these topics not only examine students' mathematical knowledge and skills, but also examine their observation and logical thinking skills, parents can encourage children to observe and think more in the process of tutoring their children, cultivate their independent thinking ability and problem-solving ability, and also hope that these practice questions can help children better grasp mathematical knowledge and improve their learning effect, this article is carefully written by the xxx education team, in order to help parents and teachers better tutor their children's learning, welcome to continue to pay attention and provide valuable feedback, we will continue to improve and improve the content, provide more valuable educational resources for everyone, wish children learningXi Jinping's progress grows up healthilychoi game danh bai! The description of the math workbook and the analysis of related questions in the above article have been more detailed÷, and this article will continue to add some specific practice questions and answers for parents' reference, and welcome valuable suggestions and feedback so that we can better meet the needs of students and parents. Analysis: This question mainly examines the student's mastery of division operations and their understanding of the concept of remainder, the minimum remainder depends on the relationship between the divisor and the quotient, according to the principle of division, the dividend = divisor× quotient + remainder, so in this problem, we can list the equation ()=5×7+remainder, because the remainder must be less than the divisor, so the minimum value of the remainder is the divisor minus one, that is, the remainder is the minimum of 4, so ()÷5=7, the remainder is the minimum is 4, so the answer is to fill in the brackets, the appropriate number is 39, and the remainder is the minimum of 4. (2) Application question: A store carries out promotional activities, the original price of a toy is 8 yuan, the current price is 7% off the original price, how much is the current price? Analysis: This question mainly examines students' understanding and calculation ability of the discount problem, first of all, we need to calculate the discounted price, that is, the original price multiplied by the discount coefficient, the original price in this question is eight yuan, the discount coefficient is seven fold, that is, the discount coefficient is according to the calculation method of the discount problem, the discounted price is equal to the original price multiplied by the discount coefficient, and the column formula is calculated as the discounted price = 8× seven folds = eight yuan× zero point seven = 5.6 yuan, so the current price is five .6 yuan two, Welcome your valuable suggestions and feedback, we hope that through your feedback, we will continue to improve and perfect our workbook to meet the needs of more students and parents, if you have any good suggestions or comments, please feel free to contact us, we will humbly accept and make corresponding adjustments and improvements, thank you again for your support and attention, I wish the children progress in learning and healthy growthchi bai! 2.
