小学数学人教版四年级下册 《小数的意义》说课稿
1、教学内容本节课是人教版小学数学四年级下册第四单元《小数的意义和性质》第一课时《小数的意义》的教学内容。小数的意义是一节概念教学课，这是在学习了“分数的初步认识”和“小数的初步认识”的基础上学习的。掌握小数的意义，是这单元教学的重点，直接关系到小数的性质、单名数和复名数相互改写等相关知识。 2、教材的重点和难点小数的初步认识是小学数学概念中较抽象，难理解的内容。一位小数是十分之几的分数的另一种表示形式。学生虽然对分数已有了初步的认识，也学过长度单位、货币单位间的进率，但理解小数的含义还是有一定的困难的。同时学生在以后的学习中，小数方面出现的很多问题是属于小数概念不清。因此，理解小数的含义(一位小数表示十分之几)既是本课时的重点、又是难点。在教学中要注意抓住分数与小数的含义的关键。

当A,C颜色相同时,先染P有4种方法,再染A,C有3种方法,然后染B有2种方法,最后染D也有2种方法.根据分步乘法计数原理知,共有4×3×2×2=48(种)方法;当A,C颜色不相同时,先染P有4种方法,再染A有3种方法,然后染C有2种方法,最后染B,D都有1种方法.根据分步乘法计数原理知,共有4×3×2×1×1=24(种)方法.综上,共有48+24=72(种)方法.故选B.答案:B5.某艺术小组有9人,每人至少会钢琴和小号中的一种乐器,其中7人会钢琴,3人会小号,从中选出会钢琴与会小号的各1人,有多少种不同的选法?解:由题意可知,在艺术小组9人中,有且仅有1人既会钢琴又会小号(把该人记为甲),只会钢琴的有6人,只会小号的有2人.把从中选出会钢琴与会小号各1人的方法分为两类.第1类,甲入选,另1人只需从其他8人中任选1人,故这类选法共8种;第2类,甲不入选,则会钢琴的只能从6个只会钢琴的人中选出,有6种不同的选法,会小号的也只能从只会小号的2人中选出,有2种不同的选法,所以这类选法共有6×2=12(种).因此共有8+12=20(种)不同的选法.
