。,教学重点,体验事件发生的等可能性和游戏规那么的公平性，初步学会用分数表示事件发生的可能性。,1,2,二、说教法学法,1、教法,“引导探究法,2、学法,以分组实践、自主探究、合作交流为主要形式的“探究学习法,三、说教学过程,1创设情境，导入新知；,2实践验证，探究新知；,3游戏活动，理解运用；,4回忆总结，举例拓展。,四、说板书设计,可能性,正面朝上,可能性相等 公平,反面朝上,1,2,1,2,你认为抛硬币决定谁开球公平吗？,第一步：根据经验，得出结论；,第二步：提出问题，操作验证；,2实践验证，探究新知,实验要求：,1. 每人抛,10次,，抛硬币时用力均匀高度适中；,2.组长负责统计相关数据填入实验报告单；,3.小组成员分工协作，看哪个小组合作最好，完成的最快。,抛的总次数,正面朝上的次数,反面朝上的次数,第一位同学,第二位同学,第三位同学,第四位同学,总计,实验报告单,组别,抛的总次数,正面朝上的次数,反面朝上的次数,第一组,第二组,第三组,第四组,第五组,第六组,第七组,第八组,第九组,第十组,总计,第一步：根据经验，得出结论；,第二步：提出问题，操作验证；,第三步：阅读材料，加深感悟。,2实践验证，探究新知,试验者,抛硬币总次数,正面朝上次数,反面朝上次数,德摩根,4092,2048,2044,蒲丰,4040,2048,1992,费勒,10000,4979,5021,皮尔逊,24000,12012,11988,罗曼若夫斯基,80640,39699,40941,“开心15分游戏,游戏规那么：,用抛骰子的方法，将每次得到的点数加起来，先得到15分者获胜。,玩一玩,怎么样设计这个转盘才公平？,玩一玩,玩一玩,玩一玩,哪一个更公平？,(4)回忆总结 举例拓展,请列举出一些学习生活、工农业生产等方面，关于“可能性的事例。,四、说板书设计,可能性,正面朝上,可能性相等
