(一) 简单应用题的数量关系是最简单的,也是最基本的。从教学简单应用题起,就交给学生解析应用题的钥匙——运用数量关系式分析应用题,为解两步和多步复合应用题打下基础。在教学中,我主要抓四个环节,培养学生三个方面的能力。四个环节是:(1)抓题目要解答的问题;(2)根据问题列出基本数量关系式;(3)根据基本数量关系式列出对应实际题意的关系式;(4)根据实际题意关系式找出与条件对应的已知数。三个方面的能力是:(1)根据问题,正确地列出基本数量关系式的能力;(2)把基本数量关
(A) the number of simple application questions the relationship is the most simple, but also the most basic. From the simple teaching of teaching questions, students should be handed over the key to the application of analytical questions - the use of quantitative analysis of the application of questions, to solve the two-step and multi-step composite application questions to lay the foundation. In teaching, I mainly focus on four aspects to develop students' abilities in three aspects. The four links are: (1) grasping the questions to be answered; (2) listing the basic quantitative relations according to the questions; (3) listing the relations that correspond to the actual questions based on the basic quantitative relations; (4) The problem relation finds the known number corresponding to the condition. The three areas are: (1) the ability to correctly list the basic quantitative relationships based on the problem; (2)
