小学数学应用题教学的第一步是掌握解题的主要步骤,还需要掌握解答应用题的基本方法。一般可以分为综合法、分析法、图解法、演示法、消元法、假定法、逆推法、列举法等。在这里介绍这些方法,主要是帮助同学掌握在遇到应用题时,如何去思考,怎样打开自己的智慧之门。这些方法都不是孤立的,在实际解题中,往往是两种或三种方法同时用到,而且有许多问题,可以用这种方法分析,也可以用那种方法分析。在掌握了各种方法后,可以随着题目中的数量关系灵活运用,切不可死记硬背,机械地套用解题方法。
The first step in the teaching of primary school mathematics problem solving is to master the main steps to solve the problem, but also need to master the basic method to solve the problem. Generally can be divided into comprehensive law, analytical method, graphic method, demonstration method, elimination method, hypothetical method, reverse method, enumeration method. Introduce these methods here, mainly to help students master the problem encountered in the application, how to think, how to open their own doors to wisdom. These methods are not isolated, the actual problem-solving, often two or three methods are used at the same time, and there are many problems, you can use this method, you can also use that method of analysis. After mastering a variety of methods, you can flexibly use the relationship between the number of questions, must not rote memorize, mechanically apply the problem-solving method.
