分数应用题是小学阶段最后一类应用题也是小学阶段应用题教学的重点之一,又是学生学习的难点。《全日制义务教育数学课程标准》中说,“应通过解决实际问题进一步培养学生的数感,应使学生经历从实际问题中抽象出数量关系,并运用所学知识解决问题的过程”。掌握分数应用题的解答方法可以培养学生的逻辑思维能力,分析问题、解答问题的能力。笔者在分数应用题教学中突出“抓、定、找、列”四个步骤,现与同行商榷于下。
Fraction application is the final stage of primary application questions is also one of the focus of primary school teaching, but also difficult for students to learn. The standard of full-time compulsory education mathematics curriculum states that “the number sense of students should be further cultivated by solving practical problems, the students should be experiencing the process of abstracting the number relations from the actual problems and using the learned knowledge to solve the problem” . Grasp the solution to the problem of application questions can develop students’ logical thinking ability, analysis of the problem, the ability to answer questions. The author points out in the teaching of fractional application “scratching, fixing, looking, column ” four steps, now discuss with colleagues in the next.
