分数应用题是小学五年级上学期重要的教学内容,更是小学阶段应用题的精华,在整个小学数学教学和学习中都是一个难点。所以五年级的小学生在做有关分数应用题时出现错误率相对比较高一些。我在多年的高年级数学教学基础上,并结合自己对分数应用题教学的经验,总结一些分数乘除应用题的解题指导方法,以期可以有助于学生学习和老师教学分数应用题。一、认真审题,找准“单位1”“单位1”的概念在四年级学习分数时就提到,所谓单
Fraction application question is an important teaching content of the fifth grade primary school last semester, but also the essence of the application questions in primary school, is a difficult point in the entire primary school mathematics teaching and learning. Therefore, the fifth grade pupils in the application of the relevant questions when the error rate is relatively high. Based on many years of advanced mathematics teaching, combined with my own experience of the teaching of fractional applications, I summed up some problem solving guidelines for multiplication and division of applied scores in order to help students learn and teachers’ teaching scores. First, earnest examination of the problem, identify the “unit 1 ” “unit 1 ” concept mentioned in the fourth grade learning scores, the so-called single
