从低年级开始,孩子们就明白,解决应用题其实就是为了解决实际问题,到了中年级,孩子们更要懂得应用题教学是小学数学教学的重要组成部分,也是教师和学生的难点。学生掌握应用题的解题策略对于提高他们的数学素养具有重要作用。三年级是学生形象思维能力向抽象思维能力过渡的关键阶段。纵观苏教版,从四年级开始才在教材中单独开辟解决问题的策略的主题单元,而三年级这方面的学习则是分散在各个主题单元之中,因此我们还是要对这方面、这些题目做一些研究,根据笔者自己的经验,打算分以下三点进行阐述。
From the very beginning of the junior year, the children understand that solving practical problems is actually a matter of solving practical problems. By the middle school, children should understand that applied questions teaching is an important part of primary school mathematics teaching as well as a challenge for teachers and students. Students master the solution problem-solving strategies for the application to improve their mathematical literacy plays an important role. The third grade is a crucial stage in the transition from students’ thinking ability to abstract thinking skills. Looking at the Sujiao version, the theme unit of the strategy for problem solving is opened up separately in the textbooks from the fourth grade. The third-grade learning in this respect is scattered among the thematic units. Therefore, Subject to do some research, according to my own experience, intended to be divided into the following three points.
