比较是小学数学教学中常用的思维方法之一.比较能使被比事物的本质特征更清楚,从而确切地认识它们之间的区别与联系,防止知识的混淆和割裂.因此教师在教学中要引导学生在观察中比较,在比较中观察,让学生知道比较是怎么回事,谁和谁比,比什么,怎么比.下面就比较在小学数学教学(中年级)中的运用谈些认识.一、利用知识间的联系进行比较,帮助学生准确地掌握知识.低年级,学生已有了初步比较大小、多少的能力,中高年级则应帮学生明确比较目的,
Comparison is one of the common thinking methods in elementary mathematics teaching.Comparison can make the nature of being more specific than the things more clearly, so as to know exactly the difference and connection between them and prevent the confusion and fragmentation of knowledge.Therefore, teachers in teaching Guide students in the observation of comparison, observed in the comparison, so that students know how is the comparison, who and who, than what, how to compare the following in primary school mathematics teaching (middle-grade) to talk about some understanding. First, the use of the connection between the knowledge to help students accurately grasp the knowledge of the lower grades, the students have a preliminary comparison of the size of how much capacity, high school should help students a clear purpose,
