小学阶段,无论是教材编排意图还是教学目标要求,需渗透、应用、培养的数学思想方法有很多种,数形结合是其中重要的一种思想方法。简而言之,数形结合思想就是根据“数”与“形”之间的对应关系,通过“数”与“形”的相互转化来解决数学问题的思想。“数”与“形”是事物两方面的属性,“数”与“形”的结合,不仅是客观事物的自然连接,更沟通了思维的联结。“数”的抽象与“形”的直观相结合,能 In the elementary school stage, there are many kinds of mathematical thinking methods that need to be infiltrated, applied and cultivated, no matter whether it is intended for teaching materials or for teaching objectives. Combination of several forms is one of the important methods of thinking. In short, the idea of ​​combining numbers and forms is to solve the problem of mathematics through the transformation of “number ” and “form ” according to the correspondence between “number ” and “form ”. “Number ” and “Shape ” are two attributes of things. The combination of “number” and “shape” not only links the natural connection of objective things, but also communicates the connection of thinking. “Number ” abstraction combined with the intuitive “” shape, can
