《课程标准(2011年版)》在“课程设计思路”中指出,“模型思想的建立是学生体会和理解数学与外部世界联系的基本途径”。由此可见,让学生初步掌握列方程解决问题的基本思考方法,感悟列方程解决问题的主要特点,对他们今后的学习和成长具有十分重要的意义。由于学生在此前的数学学习中对应用算术方法分析和解决问题已经非常熟悉,所以他们对方
Curriculum Standard (2011 Edition) pointed out in “Curriculum Design Ideas” that “the establishment of model thinking is the basic way for students to understand and understand the connection between mathematics and the outside world.” Therefore, it is of great significance for students to master the basic thinking method of solving column equations and how to understand the main characteristics of column equations in solving their problems, which are of great significance to their future study and growth. Since students are already familiar with applying mathematical methods to analyzing and solving problems in previous math studies,
