在多年的小学数学的教学实践中,我深深地感到只有帮助学生掌握分析解答两步应用题的方法,才能提高解答应用题的能力,下面谈谈九义教材三年级两步应用题的几种解题方法。一、运用图解法有些两步应用题可启发学生先画线段图,然后借助线段图在图上分析寻找到间接条件,帮助学生理解
In many years of primary school mathematics teaching practice, I deeply feel that only to help students master analytical methods to answer two-step questions in order to improve the ability to answer questions, let me talk about Way to solve problems. First, the use of graphic method Some two-step questions can inspire students to draw line segment diagram, and then use the line segment diagram in the analysis to find indirect conditions to help students understand
