简介:分类思考一般是指在解决某些问题时,根据问题的"已知"或"所求"或"已知与所求"相互间的关系,确定恰当的分类标准,依据这一分类标准,把所研究的对象分为若干种情况;然后对每种情况进行分析、思考,使问题获得解决。现举例说明如下:1.依据"所求"分类例1100人排成一列,自1起往下报数,报奇数的出列,留下的人再重新报数,这样继续下去,……,最后留下一个人,问这个人每一次报数时,报的数是多少?分析:据"所求",按每人每次报数的奇偶性这一标准进行逐次分类思考.总的人数:1,2,3,…,100。第一次报偶数的:2,4,6,…,98,100;第二次报偶数的:4,8,12,…96,100;第三次报偶数的:8,16,24,…96;
