两步应用题是由两个有联系的一步应用题组成的,其中第一个一步应用题中要求的问题正是第二个一步应用题的已知条件,这个问题(条件)就是解两步应用题首先要解决的“中间问题”。而这个中间问题是隐蔽的,教学关键是让学生学会分析,能把它揭示出来。这对初学两步应用题的学生来说有一定的困难。我在教学中运用投影、录音等多种媒体,精讲多练,较好地解决了这个问题。一、自然过渡,实现知识转化,打好教学基础。学生在学习两步应用题前,已学过各种简单的一步应用题,如果能先做好从一步应用题到两 The two-step question is composed of two connected one-step questions, where the question required in the first one-step question is the known condition of the second one-step question, and the question (condition) is the solution of two steps Application problem first to solve “intermediate problem ”. And this intermediate problem is hidden, the key to teaching is to let students learn to analyze, can reveal it. This is a beginner’s two-step application problem students have some difficulties. I use a variety of media such as projection and recording in my teaching, and talked more and practiced more effectively to solve this problem. First, the natural transition, to achieve knowledge transformation, lay a good teaching foundation. Students in the study of two-step application questions, have already learned a variety of simple application questions, if we can do a good job from one step to two
