集合是具有某种特征的事物所组成的整体,组成集合的每个事物都是集合的元素。复习中,正确地运用透渗集合思想的方法,既能使学生直观地理解一些数学概念的本质属性,又能形象具体地掌握知识间的内在联系和区别,从而使学生获得新的领悟。 1.渗透集合思想,有助于进行知识归类,使之系统化。例如,复习“数”的概念时,可先让学生判断0—9的数中,哪些是整数,哪些是
A collection is a group of things that have certain characteristics. Each thing that makes up a collection is an element of a collection. In the review, the correct application of the osmotic ensemble idea method can not only enable students to intuitively understand the essential attributes of some mathematical concepts, but also enable the image to specifically grasp the internal relations and differences between the knowledge, so as to enable the students to gain new comprehension. 1. Infiltration of collective thinking helps to classify knowledge and make it systematic. For example, when reviewing the concept of “number”, students can first determine which of the 0-9 numbers are integers and which are
