列方程解应用的重点是:分行数量关系和找等量关系列方程。这部分教学内容在小学数学教学中是一个难点。困难因素有三点:1.抽象思维难度大。学生长期习惯于按确定的数量解题,现在抽象到用字母表示数量,一时不适应;2.概括思维要求高。用x代替未知量,将未知看作已知去分析数量关系从而得方程,学生的抽象概括能力有一定距
The application of column equation solution focuses on: the relationship between the number of branches and find equal relation column equations. This part of the teaching content in primary school mathematics teaching is a difficult task. There are three difficult factors: 1. Abstract thinking difficult. Long-term students accustomed to solving the problem according to a certain number, and now abstract to the number of letters, not suited for a moment; 2. Summarized thinking demanding. Use x instead of unknowns, the unknown as known to analyze the relationship between the number to get the equation, the abstract abilities of students have a certain distance
