篇1:口算练习题
基本性质
小数末尾添上0或去掉0,小数的大小不变,但计数单位变了。而且,小数点向左移动一位、两位、三位,原来的.数就缩小10倍、100倍、1000倍,小数点向右移动一位、两位、三位,原来的数就扩大10倍、100倍、1000倍,.
意义
可从分数的意义着手,分数的意义可从子分割及合成活动来解释,当一个整体(指基准量)被等分后,在集聚其中一部份的量称为「分量」,而「分数」就是用来表示或记录这个「分量」。例如:2/5是指一个整数被分成五等分后,集聚其中二分的「分量」。当整体被分成十等分、百等分、千等分……等时,此时的分量,就使用另外一种纪录的方法-小数。例如1/10记成0.1、2/100记成0.02、5/1000记成0.005……等。其中的「.」称之为小数点,用以分隔整数部分与无法构成整数的小数部分。整数非0者称为带小数,若为0则称纯小数。由此可知,小数的意义是分数意义的一环。
写法
整数部分写在小数点前,小数部分写在小数点后,中间用小数点隔开。
读法
有两种:一种是按照分数的读法来读.带小数的整数部分按整数读法读;小数部分按分数读法读.例如:0.38读作百分之三十八,14.56读作十四又百分之五十六.另一种读法,整数部分仍按整数的读法来读,小数点读作“点”,小数部分顺次读出每个数位上的数字,若几个零重复,不可只读一个0.例如:0.45读作零点四五;56.032读作五十六点零三二;1.0005读作一点零零零五.
