列方程(组)、不等式解实际问题的一般步骤是:先审题;然后设未知数,列方程(组)或列不等式;解方程(组)或不等式;最后检验和写出答语。列方程(组)、不等武解决实际问题的关键在审题,也就是分析问题,很多学生对解实际问题存在畏惧心理,那么,教师在教学活动中如何进行引导才能使学生易于掌握对实际问题的分析呢?现在就将平时教学中运用的一套利用表格分析问题的教学方案与大家一起分享。
The general steps for solving equations (groups) and inequalities to solve practical problems are: first examine the problem; then set unknowns, list equations (groups) or column inequalities; solve the equations (groups) or inequalities; and finally test and write the answer. The key to solving equations (groups) and inequality to solve practical problems is to examine problems, that is, to analyze problems. Many students have fears about solving practical problems. Then, how teachers can guide them in teaching activities can make students easy to master practical problems. What is the analysis? Now we will use a set of teaching programs that use tables to analyze problems in our daily education.
