    人教版新课标小学数学六年级上册用百分数解决问题说课稿3篇

    2、说说下面每个百分数的具体含义,是怎么求出来的?(哪两个数相比,把谁看作单位“1”)(1)某种菜籽的出油率是36%。(2)实际用电量占计划用电量的80%。(3)李家今年荔枝产量是去年的120%。二、新授1、根据数学信息提出问题:出示例2的情境图,让学生根据图中提供的条件提出用百分数解决的问题。(1)计划造林是实际造林的百分之几?(2)实际造林是计划造林的百分之几?(3)实际造林比计划造林增加百分之几?(4)计划早林比实际造林少百分之几?2、让学生先解决前两个问提。解决这类问题要先弄清楚哪两个数相比,哪个数是单位“1”,哪一个数与单位“1”相比。3、学生自主解决“实际早林比计划增加了百分之几”的问题。(1)分析数量关系,让学生自己尝试着用线段图表示出来。

  • 人教版新课标小学数学六年级上册稍复杂的分数除法应用题说课稿

    人教版新课标小学数学六年级上册稍复杂的分数除法应用题说课稿

    教材分析:例2以学校兴趣小组为题材,引出稍复杂的已知一个数的几分之几是多少,求这个数的实际问题。用算术方法解决这样的实际问题,不仅需要逆向思考,还要把“比一个数多它的几分之几”,转化为“是一个数的几分之几”,比较抽象,思维难度大。用方程解,可以列成形如 的方程,也可以列成形如 的方程,前者仍然要经历从“多几分之几”到“是几分之几”的转化,实际上是方程的形式,算术的思路。教学重点:弄清单位“1”的量,会分析题中的数量关系。教学难点:分析题中的数量关系。学情分析:由于小学生目前尚未接触到比较复杂的,用算术方法很难解决的实际问题,所以对方程解法的优越认识不足。一些学生觉得用方程解需要写设句,比较麻烦,因此喜欢用算术解法。对此,教师一方面应肯定学生自己想到的正确解法,另一方面又要因势利导,从进一步学习的需要与方程解法的特点等角度,使学生初步了解学习列方程解决问题的重要性。从而提高学习用方程解决问题的自觉性和积极性。

    (二)归纳小结。设问:今天学了什么?什么叫轴对称图形?怎样判断轴对称图形?什么叫对称轴?怎样找出轴对称图形的对称轴?(新课后的总结能起到画龙点睛的作用,同时有利于帮助学生理清知识结构,形成完整认识。)现在能把两侧大小不同的蝴蝶图画成一模一样吗?(教师拿着新课引入时的不对称的蝴蝶图)(前后呼应,解答课前疑难,目的是检查学生活用知识的情况。)全课小结:这节课,我通过五个环节的教学设计,既遵循了概念教学的规律,又符合小学生的认知特点,指导学生操作、观察、引导概括,获取新知;同时注重培养学生的形象思维和抽象思维。在教学过程中让学生动口、动手、动眼、动脑为主的学习方法,使学生学有兴趣、学有所获。附板书设计:轴对称图形如果一条图形沿着一条直线对折,两侧的图形能够完全重合,这个图形就是轴对称图形。折痕所在的这条直线叫做对称轴。
