数学是一门高度抽象、逻辑性很强的学科,小学生思维又正好处于直观形象思维阶段,为了较好解决“抽象性”与“形象性”这对矛盾,我们不妨采用“画图解题”这把金钥匙,把抽象的数量关系转化为适当的图形,从图形的直观特征发现数量之间存在的联系,以达到化难为易,化繁为简,化隐为显的目的,使问题简捷地得以解决。我们可以根据不同的内容画不同的图。
Mathematics is a highly abstract and highly logical discipline. The thinking of primary school students is just in the stage of visual thinking. In order to solve the contradiction between “abstractness” and “imagery” better, we may wish to adopt “ Drawing the solution to the problem ”This golden key, the number of abstract relations into the appropriate graphics, intuitive features from the graphics found that there is a relationship between quantity, in order to achieve the difficult for the easy, simplification, simplification of the obvious Purpose to make the problem simple and easy to solve. We can draw different diagrams according to different contents.
