The Methods and Skills of Dealing with Elementary Mathematics Problems
The following is an example of a lesson plan design on the methods and techniques of solving elementary school math problems: ** 1. Teaching objectives ** 1. Let the students understand the common methods and techniques of solving primary school math problems, such as the techniques of examining questions and the methods of analyzing the relationship between numbers. 2. Through practical practice, students can use these methods and techniques to solve different types of primary school math problems and improve their ability to solve problems. 3. Cultivate students 'interest and confidence in mathematics learning, and improve students' flexibility in mathematics learning. ** 2. Important and Difficult Points in Teaching ** 1. ** Main point ** - Master the key points of the examination, such as finding out the key information and understanding the requirements of the question. - Learn to analyze the relationship between different types of questions (such as application questions, calculation questions, etc.). - Master some basic problem solving skills, such as drawing, listing, etc. in solving problems. 2. ** Difficulty ** - Able to accurately choose appropriate methods and techniques to solve complex numerical relationships. - Cultivate the students 'ability to flexibly apply the methods and techniques they have learned to different topic situations. ** 3. Teaching Method ** Combination of lecture method, practice method and discussion method ** 4. Teaching process ** #(1) Introduction (5 minutes) 1. By showing a typical elementary school math problem (such as an applied problem involving multiple numbers), it would arouse the students 'interest. 2. Ask the students what their first reaction was when they saw the question. Guide the students to think about the difficult points in solving the question. #(2) Explanation of methods and techniques (20 minutes) 1. ** Exam Review Skills ** - He emphasized the importance of reading the questions carefully and understanding the meaning of the questions word by word. - Find out the known and unknown conditions in the question. For example, in the application question, clearly give the number, quantity, and the content that needs to be solved. - Pay special attention to key words such as "total,""remaining,""more than..." and "less than...". These words often imply a quantitative relationship. 2. ** Analyzing the relationship between quantity and quantity ** - For simple calculation questions, explain how to analyze the relationship between numbers according to the calculation rules. For example, in the four arithmetic operations, the order of multiplication and division followed by addition and deduction was determined based on the logical relationship of mathematical operations. - In the application questions, introduce the commonly used methods to analyze the relationship between quantities. - Drawing method: Take a journey problem as an example. For example, if A and B set off from A and B at the same time, they would travel in opposite directions. Given A's speed, B's speed, and the distance between the two places, find the time of encounter. By drawing a line diagram to show the route of A and B and the relationship between them, the students could see the relationship between distance, speed and time. - [Tabulation method: For some questions that involve the relationship between the quantity and price of many items, such as the quantity and total price of different fruits, you can make a table and clearly list the unit price, quantity, and total price of each fruit to find out the quantity relationship.] - Guide the students to establish a mathematical model based on the quantitative relationship in the question. For example, establish the equation model of distance = speed x time in the above-mentioned travel problem. 3. ** The application of problem solving skills ** - It introduced some special problem solving techniques, such as the application of rounding method in simple addition and substitution. For example, to calculate 98 + 35, 98 could be rounded up to 100 and converted to 100 + 35 - 2 to quickly calculate. - For multiple-choice questions, one could use substitution and elimination techniques. Take a multiple-choice question about comparing the size of numbers as an example. Substitute the numbers in the options into the conditions of the question to verify or eliminate the obviously wrong options according to some basic mathematical properties. #(3) Practice (15 minutes) 1. He gave a few different types of elementary math questions, including simple calculation questions and application questions, for the students to practice independently. For example: - Calculation: 34 + 29 + 66 - There are 120 storybooks in the school library, and 30 fewer science and technology books than storybooks. How many books are there in total? 2. Inspecting the students 'practice, giving timely guidance and help, reminding the students to use the methods and techniques they have learned to solve problems. #(4) Group discussion and sharing (10 minutes) 1. The students were divided into groups of 4 - 5 people. 2. Ask the students to discuss the problems they encountered in the process of solving the problem, the methods and techniques they used, and the ideas they used to solve the problem. 3. Each group elected a representative to share the results of the group's discussion, including the most helpful solution, the difficulties encountered, and how to overcome them. #(5) Summing up and Consolidating (10 minutes) 1. He summarized the methods and techniques for solving primary school math problems in this lesson and emphasized the importance of examining questions, analyzing quantitative relationships, and using solving techniques. 2. After class, the students were asked to complete a few similar math problems to consolidate their knowledge. The homework questions could include different levels of difficulty to meet the needs of different students. Read more exciting novels for free
Battle Through the Heavens
