在分数教学备课时,细心的老师都会重视与旧知识整数的联系比较。并在此基础上探讨它们的异同,加强相互之间的沟通,形成知识网络,同时又以此服务于教学。一、分数与整数的关系分数教学备课中,要重视联系整数,弄清两者之间的关系。分数与整数(0除外)可以认为都是以1为基础,聚“1”则成整数,分“1”则成分数。这是它们之间的基本关系。当然分数与整数是两种不同的数,它们的计数单位不同。且整数没有最大的,分数则没有最小的。
During the lesson preparation lesson, attentive teachers will value comparison with the old knowledge integer. On the basis of this, I will discuss their similarities and differences, strengthen mutual communication and form a knowledge network, meanwhile serve as a teaching basis. First, the relationship between scores and integers Score teaching lesson preparation, should pay attention to contact integer, to clarify the relationship between the two. Points and integers (except 0) can be considered as 1 based, poly “1” is an integer, divided by “1” is the number of components. This is the basic relationship between them. Of course, scores and integers are two different numbers, and their counting units are different. And the integer is not the largest, the score is not the smallest.
