在整个小学阶段应用题教学的系统工程中,简单应用题教学是基础。打好这个基础很重要。在教学简单应用题时,为了达到使学生既能懂得用什么方法去解,又懂得为什么要用这个方法解的目的,教师在引导学生分析数量关系的过程中,就要注重让学生学会两个转化,即把应用题中的日常语言转化为数学语言,再把数学语言转化为数学式子。实践证明,学生能把一道简单应用题概括为一道相应的文字题,进而根据基本概念列出算式,就能够真正地理解简单应用题的数量关系。
In the whole primary school of applied problem teaching system engineering, simple application problem teaching is the foundation. It is important to lay this foundation. In the teaching of simple application questions, in order to achieve so that students can understand both ways to solve, but also understand why the purpose of using this method of solution, the teacher in guiding students to analyze the relationship between quantity, we should focus on allowing students to learn two Conversion, that is, the application of the daily language into a mathematical language, then the mathematical language into mathematical formulas. Practice has proved that students can summarize a simple application questions as a corresponding word problem, and then formulating formulas based on the basic concepts, we can really understand the relationship between the number of simple application questions.
