习题是课堂教学的重要素材,是培养学生数学思维品质的重要载体。在当下的数学教学中,仍然有不少教师就习题练习题、讲习题,一味死搬教材,从而削弱了教材习题的功能,在一定程度上制约了学生的发展。为此,对教材习题进行二度开发,应成为数学教师共同关注的问题。一、情境辅助——突出应用价值教材上的许多习题是按照数学知识的逻辑性和系统性进行设计的,缺少数学知识应用于生活实际的联系。这样的习题对学生来 Exercises are important materials for classroom teaching and are important carriers for cultivating students’ mathematical thinking qualities. In the current mathematics teaching, there are still many teachers who have practiced the exercises and taught the exercises, and have been blindly carrying textbooks, thereby weakening the function of textbook exercises and restricting the development of students to a certain extent. For this reason, the second development of the exercise materials should become a common concern of mathematics teachers. First, Situational Aids - Outstanding Application Values ​​Many exercises in textbooks are designed according to the logical and systematic nature of mathematical knowledge, and lack the application of mathematical knowledge to the actual connection of life. Such exercises are for students
