Regarding Lai Changxing's Dream of the Red Chamber,

The following is an example of a lesson plan for explaining the absolute value problem in seventh grade mathematics: ** 1. Teaching Purpose ** Through the distance between the point on the number axis and the origin, the concept of the absolute value of rational numbers is introduced, so that students can learn to find the absolute value of a number. ** 2. Teaching Focus ** Find the absolute value of a number. ** 3. Key to Teaching ** The significance of the absolute value on the number axis. ** 4. Teaching process ** 1. ** Teaching Introduction ** - In a game in PE class, four students stood on a circle and competed to see who could reach the center of the circle first. Ask the students whether the distance between the four students to the center is equal and whether the direction affects the length of the distance. Guide the students to come to the conclusion that the distance is equal regardless of the direction. - Citing example 2: Ask the students to find which points on the number axis have the same distance from the origin, such as the distance between 1 and-1 to the origin, so as to introduce the concept of absolute value. 2. ** Concepts and examples ** - ** Concept explanation **: The distance between the point on the number axis that represents the number 'a' and the origin is called the absolute value of the number 'a' and is recorded as 'a' vert'. For example, the absolute value of 6 on the number axis is 6, and the absolute value of 100 is 100. - ** Practice * - Try to answer the absolute value of simple numbers, such as <<Vert2>>,<<Vert -5.2>>,<<Vert -5.2>>,<<Vert-5.2>>. - Find the absolute values of the numbers, such as 4.7, 51, and 0.5. - Let the students do the exercises related to exercise P3 in the book. - ** Method of Calculating Absolute Value ** - The absolute value of a positive number is itself; the absolute value of zero is zero; the absolute value of a negative number is its opposite. In mathematical terms, when a>0, a = 0; when a = 0, a =0; when a<0, a =-a. - ** Explanation of examples ** - Calculating the values of <<Vert12>-<225>,<<Vert10>,<<Vert -39>>, and comparing the quality of the volleyball (For example, the absolute value of the difference between the quality of the volleyball and the standard quality is given. The smaller the absolute value, the better the quality), the students can use the absolute value knowledge to explain. - For questions such as <x>= 2>,<y>= 5>, and <x>= y>, find the values of <x> and <y>. Because when <<p> x><p>= 2>,<<p> x>= 2>,<p> x>= pm2>,<p> y>= 5>,<p>,<p> x>= pm2>,<p> y>=-5>. - For the problem of finding the value of the algebraic expression, if the absolute value of m is 2, and m and n are the opposite of each other, c and d are the reciprocals of each other, and the absolute value of m is 2. According to the conditions, we first get the values of m= pm2 and c = 1, then we substitute them into the calculation. ** 5. Inadequacies in teaching reflection ** 1. ** Students 'level difference is not enough ** - In the teaching process, due to the different levels of students, students could basically find a variety of solutions to an equation that only contained one absolute value. However, for a situation with two absolute values, most students had no way to start. In the future, he should pay attention to the design of teaching grades, reduce the span, and be closer to the students 'learning ability. 2. ** The teaching of the geometric meaning of absolute value needs to be strengthened ** - In teaching, we should further strengthen the teaching of the geometric meaning of absolute value and improve the students 'ability to combine numbers and shapes. This will help students better understand the concept of absolute value and solve more complicated problems related to absolute value. 3. ** Practice level settings can be optimized ** - In the practice segment, although the requirements were divided into two levels, they could be further optimized. For example, for students with weaker foundations, they could add more simple practice questions directly related to the concept of absolute value to help them master the basic knowledge. For students who had the ability to learn, they could add some expansive questions that required comprehensive application of knowledge to better meet the needs of students at different levels. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
