2、会找有关成数实际问题的数量关系并掌握解答方法。
3、体会成数与生活的密切联系,增强探索和合作交流的意识。
二、教学重难点
教学重点:理解成数的含义,掌握成数与百分数之间的关系。教学难点:会找有关成数实际问题的数量关系并掌握解答方法。
三、教学准备
多媒体课件。
四、教学过程
(一)引课
(板书课题──成数)
1、播放谁参加比赛的视频,初步感受成数。
师:视频中的九成、十成是什么意思?谁先来说一说?谁还想来说一说?谁还有不同的理解?那是不是你们说的那样呢?我们这一节课就一起来研究有关成数的问题。
学生:畅所欲言。教师:适时鼓励,过度。
2、出示课题。
师:首先我们一起来看看这节课学习目标。
3、课件出示学习目标,要求学生默读学习目标。教师板书课题:成数问题 学生:认真默读学习目标。
(二)新授课
1、自学成数的意义。课件出示成数的意义资料:
对于农业收成、工业生产等,经常用“成数”来表示。成数表示一个数是另一个数的十分之几,通称“几成”。
例如,“二成”就是十分之二,该写成百分数是20%; “三成五”是十分之三点五,改写成百分数就是35%。
师:同学们明确了这节课的学习目标了吗?现在请大家自学成数,思考什么是成数,并完成作业纸检测题一。生:认真自学,并完成检测题一。
教师巡视,发现学生的错误,并记录,以备学生汇报。检测题一
(1)五成=()/10 =()%。(2)四成五=()/10 =()%。(3)70% =()/10 =(成)=(折)学生口答,教师填写,并对刚刚发现的错误,让会的同学进行进行讲解更正。对于学生的回答适时点评。
师:有错误的同学请举手,现在会了吗?请快速更正。
2、解决与“成数”相关的问题(1)自学例题1 师:我们已经认识了成数,大家有没有信心解决生活中的成数问题呢?
课件出示教材第64页例1:认真看图看文字,图中售货员和经理正在讨论电视机的售价问题,你了解到哪些数学信息?
思考:
1、经理说的“加二成”是什么意思?
2、请您尝试列式并解答。
师:请同学们认真自学例题1,认真思考并解决老师给出的两个问题
教师巡视,发现学生解答的过程并及时记录已准备学生反馈。学生可能有以下解题思路:
思路一:加二成,就是电视机的售价比进价提高二成。也就是电视机的售价比进价提高20%,那么,单位“1”是电视机的进价,已知。电视机的售价是进价的(1+20%),即1800×(1+20%)。
思路二:加二成,就是电视机的售价比进价提高二成。也就是电视机的售价比进价提高20%,那么,单位“1”是电视机的进价,已知。提高了单位“1”进价的20%,售价等于进价加上提高的价钱,即1800+1800×20%。
③在发现学生错误,让会的学生进行讲解,在学生讲解的同时,教师板书: 1800×(1+20%)1800+1800×20% =1800×120% =1800+360 =2160 =2160 ④师:有错误的同学举手,现在明白了吗?快速更正错误。
⑤师:选择你喜欢的解决成数问题的方法,和你的同桌交流一下,讲一讲。教师小结:可以根据自己的理解和计算能力,选择合适的方法进行计算。(2)第一关:类比练习
师:同学们例题1你们会了,老师想看看你们能不能闯过今天的第一关。课件出示教材第65页“做一做”第1题:王大爷的这块地去年产玉米4050千克,看今年的涨势大概能比去年增产一成。预计今年可产玉米多少千克?(只列式不计算)
①读题,学生独立完成再进行集体校对。
②教师巡视,并进行个别辅导,抓住学生的生成,及时点拨。③汇报交流解题思路,并说说如何解决这类“成数”的问题。
思路一:今年涨势大概能比去年增产一成,就是今年的产量比去年的产量增加10%,今年的产量是去年产量的(1+10%),即4050×(1+10%)。
思路二:今年涨势大概能比去年增产一成,就是今年的产量比去年的产量增加10%,增加了去年产量的10%,今年的产量等于去年的产量加上增加的产量,是4050+4050×10%。
师:有错误的同学举手,现在明白了吗?快速更正错误。(3)第二关:举一反三
师:上面的题没有难住大家,第二关这道题你们会吗?看看与第一关有什么不同? 课件出示教材64页例题2,:曹庄乡去年产棉花400吨,今年遭受虫害,大概要减产一成五,今年大约产棉花多少吨? ①读题,学生独立完成再进行集体校对。
②教师巡视,并进行个别辅导,抓住学生的生成,及时点拨。③汇报交流解题思路,思路一:题中大概要减产一成五,就是今年的棉花产量比去年减少一成五,也就是今年的棉花产量比去年棉花产量减少15%,今年的棉花产量就是去年的棉花产量的(1-15%),是400×(1-15%)
思路二:题中大概要减产一成五,就是今年的棉花产量比去年减少一成五,也就是今年的棉花产量比去年棉花产量减少15%,减少了去年的棉花产量的15%,今年的棉花产量等于去年的棉花产量减去减少的棉花产量,即400-400×15% ③核对答案,教师强调书写格式写综合算式,要脱式计算。(4)第三关选择题:综合提升
师:第二关大家完成的非常好,必须提升难度,大家有信心闯过第三关吗?(1)课件出示教材65页试一试。
一种计算机现在的售价是7320元,比去年同期降价二成五。去年同期这种计算机的售价是多少元?
A、7320×(1+25%)B、7320÷(1+25%)C、7320÷(1-25%)D、7320×(1-25%)①读题,学生独立完成再进行集体校对。
②教师巡视,并进行个别辅导,抓住学生的生成,及时点拨。③指名学生汇报交流解题思路,通过读题,④师:既然大家知道单位“1”未知,那你们会用方程解决这道题吗?
⑤生:汇报。解设:去年同期计算机的售价为x元,可得方程为x(1-25%)=7320,方程的解就是去年同期计算的价格。
③学生总结,在单位“1”未知时,如何解决成数问题。(5)第四关连线题,对比练习
师:恭喜大家已经顺利通过前面的三关,现在还剩下最后一关,你们有没有信心迅速通关?
1、一个苹果园去年产苹果7500 千克。今年春天有风灾,可能要减产 二成五,预计今年产苹果多少千克?
2、一个苹果园今年的产量7500千克,今年春天有风灾,今年比去年 减产二成五,问去年产苹果多少千
① 7500×(1+25%)
② 7500÷(1+25%)③ 7500÷(1-25%)④ 7500×(1-25%)
克? ①学生独立解答,完成后并在小组内讨论做题思路。②指名学生进行汇报。
③对比这两道题,再次引导学生总结出解决成数问题的一般方法。(6)课堂小结 ①回顾学习目标
师:同学们今天这堂课你达到了学习目标了吗? ②师:这节课我们一起学习了有关成数的知识,你们对成数的知识有哪些了解呢? 生1:我知道二成等于十分之二等于百分之二十。
生2:我知道了可以将成数问题转化为百分数应用题来解决。......(7)课堂作业
所有学生快速整理作业单。(8)课后提升
课件出示教材65页第4题。
【设计意图】练习的设置和安排有层次性和针对性,教师对于练习的辅导也相应有层次性,简单的题由学生自行梳理、分析、解答,易错题和难题进行针对性点拨,对于学生对数学的学习应用也大有益处。
五、板书设计
成数问题
学生是学习的主体, 是学习的主动参与者和知识的建构者。教师在教学中起主导作用, 是学生实践的组织者、引导者。本节课首先设置一个具体实例, 引起学生探究欲望和学习兴趣, 然后教师引导学生经历观察、猜想、实际操作验证、分析归纳推理等教学活动过程, 培养学生严谨的科学态度, 发展学生动手操作、自主探究、合作交流和分析归纳的能力。
二、教学过程设计
1. 创设问题情境, 引入新课。
(1) (大屏幕显示) 现有一块碎的圆形玻璃镜子片, 想重新去玻璃店配一块同样大小的圆形玻璃镜子, 请问这块残片还有用吗?怎样去配制呢?同学们想不想解决这个问题?
学生们异口同声:想 (兴趣高涨) 。
师:这个问题就是本节课学习的一个知识点, 相信同学们通过本节课的学习能解决这个问题。
(师出示课题, “过三点的圆”)
2. 动手操作, 合作探究。
师:过一个己知点A画圆, 你有什么结论?
(学生通过自己动手、合作交流, 发现过一点可以画无数个圆)
师:谁能解释一下这一现象?
学生1:要画圆必须先确定圆心和半径, 而过一个已知点画圆, 圆心与半径都不是唯一的, 所以可以画无数个圆。
师:通过刚才的讨论, 最终我们有什么发现?
学生2:过一点可以画无数个圆;
师: (大屏幕) 过己知两点A、B两画圆?
(学生动手操作、合作交流, 请小组派代表把结论展示一下)
学生3:过两点可以画无数个圆。
(其它学生踊跃发言)
学生4:这些圆的圆心都在线段AB的垂直平分线上。
(有的学生提出疑问:“为什么”?)
学生5:∵O1A=O2B
O1A=O2B
∴O1O2是线段AB的垂直平分线
如果没有疑问, 请同学们总结一下通过刚才的活动, 我们有什么新的发现?
学生6:过两点有无数个圆, 圆心在连结这两点的线段的平分线上。
师:我们以上研究了过己知一个点、两个点作圆的情况, 接下来你还想研究什么?
学生:那么过同一平面内三个点的情况会怎么样呢?
(学生迫不及待在平面上任意取三点, 自己动手画一画。)
学生7:老师取三点不能画圆。。
师:真的吗? (师表示惊讶)
学生8、9:老师真的。
其他学生大声嚷嚷, 老师能画。
师:为什么有的能画, 而有的不能画呢?
(师把两种情总的图形分别在大屏幕上演示, 并找相应的同学边指着屏幕边解释。)
学生10:因为AB的垂直平分线与BC的的垂直平分线是平行的, 没有交点, 因此找不到圆心。这说明了过在同一直线上的三点不能画圆。
(看起来同学们都很投入)
师:既然这样, 我们就不研究这种情况了, 凡是取的三点在同一直线上的同学, 马上换方式取不在同一直线上的三点, 看看结果怎样?
师稍等片刻, 学生11上前指着屏幕解释, 过AB两点的圆的圆心在AB的垂直平分线上, 过B、C两点圆的圆心在B、C的垂直平分线上, 过A、C两点圆的圆心在AC的垂直平分线上, 所以画三条线段的垂直平分线, 交点即为圆心。
学生12:没有必要画三条垂直平分线, 两条就足够了,
学生13:老师这样的圆是不是只能画一个?师:谁能不能解释一下?
师:谁能不能解释一下?
学生14:因为交点只有一个, 所以圆心位置就确定了。
师:很好, 经过不在同一直线上的三个点, 可以画一个圆, 并且这样的圆只有一个, 可以简单地表示为:不在同一直线上的三个点确定一个圆, 板书:向学生讲解“确定”的含义, 过不在一直线上的三点能作圆并且只能作一个圆 (有且只有一个)
3. 例题教学, 规范格式。
师:同学们打开书看一下外接圆, 外心的概念并齐声朗读。
(学生朗读)
(师出示例题, 己知△ABC, 作△ABC的外接圆)
学生B, 老师不用画了, 只要我们把所取的三点连结起来就画出了三角形, 三角形的外接圆我们都画出来了。
师:既然不用再画了, 你们通过画图看一下三解形外心有什么性质。
学生15:三角形外心是三边 (其实两边就可以) 垂直平分线的交点。
学生16:三角形的外心到三角形的三个顶点的跟离相等。
师:都认可吗?
(学生们表示认可)
师:我们知道了三角形外心的性质, 外心的位置又在哪呢?
师:为什么会出现三种不同的位置呢?
(学生讨论)
学生19这是由三角形的形状确定的, 如果是锐角三角形, 外心在三角形内部, 钝角三角形在三角形的外部, 直角三角形在斜边的中点上。 (大屏幕出示)
师:说的非常好, 这里体现了数学上的分类讨论思想, 同学们应该注意。 (师解释直角三角形的外心为什么在斜边的中点上?)
4. 变式训练, 培养能力。
师:学了新知识, 我们能不能解决前面的问题呢?
(学生讲述解决办法)
(1) 在残片上任取三点A、B、C, 连结AB、AC。
(2) 分别作AB、AC的垂直平分线, 并交于一点O, O为圆心。
(3) 连结OA、OA为半径, 画圆即可。
三、教学反思
1. 重视数学基础知识的掌握。
如不在一条直线上的三点确定一个圆, 三角形外心的性质、位置等。
2. 重视数学思想方法的渗透。
如体会数学分类讨论思想, 体会类比思想。
3. 注重学生数学知识的建构。
教师首先设置一个具体实例, 引起学生探究欲望和学习兴趣, 然后教师引导学生经历观察、猜想、实际操作验证、分析归纳推理等教学活动过程, 培养学生严谨的科学态度, 发展学生动手操作、自主探究、合作交流和分析归纳的能力。
4. 思路清晰, 由情境激发兴趣。
关键词:英语语法;时态;词性;句子成份;复合句
冀教版初中英语教材语法内容只是渗透在教材之中,没有单独进行总结和归纳。怎样才能使学生学好语法内容并灵活地运用呢?笔者结合四年多新课标冀教版教材的应用谈谈自己的体会。
一、总结教材中所渗透的时态
英语每个句子至少包含一种时态,如果不让学生总结每种时态的构成式,学生很难学会造句,从而就会感到学习困难,甚至厌学。教学本教材时,我认为先学习教材中的句式,再通过句式中渗透的语法内容总结出其规律,然后让学生记住这一规律,并能够运用这一规律造出新的句子。采取这种“先……再……然后……”的模式,学生会越练越想练,越说越想说,从而对学习英语产生兴趣。如:含有实义动词的“一般现在时”,其构成规律是:“主语加动词原形……”或“主语第三人称单数加动词第三人称单数形式……”。如:I like English. He likes English.当谓语动词部分中,含有助动词do或does时,谓语动词一律用原形。如:I don'tlike English.He doesn't like English.Do you like English? Does he like English?Don't be late!等等。如果把含有实义动词的“一般现在时”,改为“一般过去时”,除时间状语作相应的变化外,在陈述句的肯定句中,实义动词一律用过去式,没有人称和数的变化。如果在否定句中和疑问句中,只把助动词do或does改为did,而实义动词一律用原形。如:陈述句的肯定式:He helped me yesterday.They came back home last week.陈述句的否定式:“He didn't help me yesterday.They didn't come back home last week.一般疑问句:Did he help you yesterday? Did they come back home last week?如果把含有实义动词的“一般现在时”,改为“一般将来时”,除时间状语要用表示将来的时间外,谓语部分一律用will/shall或am/is/are going to 加动词原形(进行时或其它形式表示将来的除外),只是在疑问句中把will/shall或am/is/are提到主语之前。在陈述句的肯定式或否定式中,把will/shall放在主语之后。如:陈述句:He walks to school every day.He won't walk to school tomorrow.He is going to ride to school tomorrow.一般疑问句:Will he walk to school tomorrow?ls he going to ride to school tomorrow?等等。如果将主动语态的“一般现在时”改为被动语态的“一般现在时”,主动语态的宾语变成被动语态的主语,主动语态的主语要变成被动语态介宾或省略。如:主动语态:We learn English.→被动语态:English is learnt (by us)。不论是主动语态中的各种时态还是被动语态中的各种时态,都分别进行总结归纳,使其简单化,使学生感到英语有规律可寻,能走一些捷径,提高了效率,同时也提
高了学生的学习兴趣。
二、认识词性和句子成份
若要造出合理的句子,就得了解句子中的成份,以及组成句子的词的词性。尤其是书面用语不能写出不符合句子成份规范的错误句子。使用冀教版英语教材进行教学时,我适时地补教了这部分内容。主语常由名词或相当于名词的词担任,置于句首。谓语或谓语动词常由动词担任,置于主语之后。表语是表述主语的身份或特征的,常由名词或形容词担任,置于系动词之后。宾语常由名词或相当于名词的词来担任,置于及物动词或介词等之后。定语是限定或修饰名词的词或相当于名词的词,常由形容词或相当于形容词的短语或从句担任。形容词常置于名词之前,相当于形容词的短语或从句常置于名词之后。状语是修饰动词、形容词、副词以及全句的,常由副词或相当于副词的短语或从句担任。修饰动词时,可置于动词之前,也可置于动词之后;修饰形容词或副词时,常置于它们之前。通过讲句子成份和词的用法,帮学生寻找规律,使他们能造出合理的句子,从而写出更好的短文。
三、突破复合句中的难点
在复合句中,难点是地点状语从句与定语从句的区别及that引导同位语从句与that引导定语从句的区别。
1.where引导的定语从句:从句前应有一个表示地点的名词作先行词,先行词在从句中必须充当状语。地点状语从句则没有表地点的名词充当状语。如:Go back to the village where you came from.(定语从句);Go back where you came from.(状语从句)
2.在抽象名词answer,belief,fact,hope,idea,news等词之后可用that引导同位语从句。同位语从句引导词无意义,不充当成份,不可省略。如:I had no idea that you were here.同位语从句与其说明的名词或代词应为同一内容,同位语从句前一般没有逗号。关系代词that引导的定语从句,先行词即可指人又可指物,在从句中作主语或宾语。在讲清楚的基础上,反复练习,用此方法来达到突破难点的目的。
