小学生在列方程解应用题前,已经学过用算术方法解应用题,加减存在部总关系,乘除存在份总关系。在分析方法上有:分析、综合、图解三种方法。列方程解应用题,这些解题规律是否还适用呢?尤其是算术用减的,列方程就用加;算术用除的,列方程要用乘,这些和解应用题如何统一呢?经过教学实践,我认为列方程解应用题和算 Primary school students in the column equation solution before the application, have learned to solve the application of arithmetic problems, add and subtract the total relationship exists, multiply and divide the existence of the total relationship. In the analysis methods are: analysis, synthesis, graphical three ways. Column equation solution to the problem, the problem-solving law is still applicable to it? In particular, the arithmetic reduction, the column equation is added; arithmetic used in addition to the column equation to multiply, how to reconcile these problems How to unify? Through teaching practice , I think the column equation solution and calculation operator
