Elementary school mathematics problem solving process ideas teaching plan design
The following is an example of an elementary school mathematics problem solving process: ** 1. Teaching objectives ** 1. To let the students grasp the basic ideas and methods to solve the common problems in primary school mathematics. 2. Cultivate students 'ability to analyze problems, propose solutions, and calculate accurately. 3. To raise the students 'awareness of using mathematical knowledge to solve real-life problems. ** 2. Important and Difficult Points in Teaching ** 1. ** Main point ** - Understand the mathematical relationships in the problem and construct a solution. - Correct use of mathematical knowledge such as the four operations to solve problems. 2. ** Difficulty ** - Able to accurately find key information and convert it into mathematical expressions for complex problems. ** 3. Teaching Method ** Teaching method, practice method, and discussion method combined. ** 4. Teaching process ** 1. ** import (5 minutes)** - Show a simple math problem situation, for example,"Xiaoming has five apples, and Xiaohong has three more apples than Xiaoming. How many apples does Xiaohong have?" Lead the students to think and answer, review the application of simple addition, and lead to the topic of solving problems in this lesson. 2. ** New (20 minutes)** - It presented various types of elementary school mathematics problems, such as addition, substitution, multiplication, and division related application problems, gradually guiding students to analyze the problems. - "The school library has three shelves, each shelf has eight shelves, and each shelf can hold five books. How many books can this library hold?" For example. - The first step was to read the question and understand the meaning. Students were required to read the questions carefully and find the known information (3 shelves, 8 shelves per shelf, 5 books per shelf) and the question (the total number of books that the library could hold). - The second step was to analyze the relationship between quantity and quantity. Students were guided to think about the relationship between these known information. Here, the total number of books was obtained by the number of shelves x the number of shelves on each floor x the number of books in each shelf. - The third step was to list the formulas and calculate. According to the analysis, the formula was 3×8×5 = 120 copies. - Then, he gave a few similar examples and asked the students to discuss the solution in groups. Then, he asked the group representative to speak and the teacher to comment and supplement. 3. ** Practice (15 minutes)** - He arranged some practice questions of different difficulty levels, such as: - [Basic question: A car travels 60 kilometers per hour for three hours. How many kilometers has it traveled?] - The school organized a spring outing for the students and rented four buses. Each bus could seat 45 students. 120 students had already boarded the bus. How many seats were left? - The students were allowed to complete the exercises independently. The teacher would patrol and guide the students to correct the mistakes in the process of solving the questions and calculations in a timely manner. 4. ** Wrap-up (5 minutes)** - Guide the students to review what they have learned in this lesson and summarize the general ideas for solving primary school mathematics problems: read the questions, analyze the quantitative relations, and list the formulas to calculate. - It emphasized the importance of reading the questions carefully, finding out the known information and problems accurately, and analyzing the relationship between quantity and quantity. ** 5. Extension of Teaching ** Arrange homework for the students to find math problems from their daily lives and answer them according to the solution ideas learned in this class. They will share and communicate with each other in the next class. Read more exciting novels for free
