多年的教学实践,笔者总结出了应用题的几种训练方法,现归纳如下,目的在于共同探讨提高:一、基础训练第一步;教师出示两个已知数据,让学生自选内容,口编几种基本应用题。第二步:将几种基本应用题先按“相并关系、相差关系、倍数关系、份总数关系”分类选题。再按“总数与部分数”、“大小两数相比”两类,继续进行选题入类的练习。第三步;

Years of teaching practice, the author summed up the application of several training methods, are summarized as follows, the purpose is to jointly explore and improve: First, the first step in basic training; teachers produce two known data for students to choose content, oral Several basic application questions. The second step: the first few basic application questions by “phase and the relationship, the difference between the multiple relationship, the relationship between the total number of” classification topics. Press “total number and the number of parts ”, “size two compared to” two categories, continue to select topics into the class exercises. third step;
