应用题是小学数学内容的重要组成部分,也是以后继续学习的知识基础。解答应用题,是综合运用知识并巩固知识的一种活动过程,也是发展观察想象能力、逻辑思维能力和语言表达能力的重要途径。其解题思路训练有十余法。本文仅对用“转化”、“假设”两法解题谈一点粗浅看法。 一、应用题解题思路——假设 什么是假设法?众所周知的阿基米德的称王冠实验中应用的思考方法,就是假设法。即是先对题目的
Application questions are an important part of primary school mathematics content, but also the basis for further study. Answering application questions is an activity process that integrates and consolidates knowledge. It is also an important way to develop the ability to observe imagination, logical thinking and language expression. The problem-solving train of thought has more than ten laws. This article only talks about the solution to the two problems of “transformation” and “what-if”. First, the application problem solving ideas - assuming what is the hypothetical method? As we all know, Archimedes' method of thinking in the application of the crown test is hypothetical. That is the first topic
