小学中年级应用题教学重点是使学生在熟练掌握两步计算应用题的基础上,掌握常见的数量关系,学会用综合算式解答三步计算的复合应用题,并能灵活选用比较简便的解答方法。为完成好这一教学任务,我在实际应用题教学中有意进行了三步计算的复合应用题思维训练的研究与实践,收到了良好的教学效果。一、努力进行解题思路训练,培养学生初步逻辑思维能力教学三步计算复合应用题的关键是让学生熟练掌握用分析法、综合法分析题中数量关系的方法,努力进行解题思
Primary middle school grade teaching questions focus is to enable students to master the two-step calculation of application problems based on the master of the relationship between the number of common, learn to use comprehensive algorithms to solve the three-step calculation of the composite application questions, and the flexibility to use simple answers . In order to accomplish this teaching task well, I deliberately conducted the research and practice of three-step computational thinking training of composite application questions in practical teaching, and received good teaching results. First, efforts to solve problem train of thought, training students initial logical thinking ability Teaching three-step calculation The problem of compound application is to make students master analytical method, comprehensive method to analyze the quantitative relationship between the number of questions, and strive to solve problems
