数的整除的知识属于整数范围,是在学过整数的计算和整数四则混合运算的基础上进行教学的。其目的是为了进一步学习分数打基础,也使学生获得一些有关整数的新知识。还可以为以后学因式分解等中学数学知识作些准备,也有助于学生抽象思维的发展,是整个小学阶 The division of the number of knowledge belongs to the range of integers, is learned in the calculation of integer and integer four arithmetic operation based on teaching. Its purpose is to learn more about the basics of scores and to give students some new knowledge about integers. But also for future school-based factoring and other secondary school mathematics to prepare for knowledge, but also help students the development of abstract thinking is the entire primary school
