区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?

教学目的:1、通过贴近学生生活实际的素材,在丰富多彩的实践活动中充分体会时、分、秒的实际意义。2、通过练习,学生比较熟练地进行一些简单的时间计算教学重、难点:时间单位的简单转换和求经过时间的方法。教学过程:第2题,先让学生独立完成,再让学生说一说每一题是怎么比较的,允许学生用不同的方法进行比较,只要说得有道理就行。第3题,读读书上的三个例子,并要求学生收集类似的信息。第4、5题,学生计算经过的时间。如果部分学生有困难,让他们借助钟面模型加以演示、理解,教师给予适当的帮助。第6题,要求学生先估计,再实际进行验证,验证的数据可以由学生和家长一起完成。第7题,事先让学生找几个自己感兴趣的节目,想办法把它们开始和结束的时刻都记录下来。
方法三:我先把数字1放在个位,然后把数字2和3分别放在十位组成21和31;我再把数字2放在个位,然后把数字1和3分别放在十位组成12和32;我再把数字3放在个位,然后把数字1和2分别放在十位组成13和23,一共摆出了6个两位数。(21、31、12、32、13、23)每种方法说完后师问:还能摆吗?(再摆就要重复了!提示:不能遗漏也不能重复)师小结:排数的时候按照一定的顺序既不会重复也不会遗漏。我们用3个不同的一位数拼成了几个不同的两位数?(板书:6个)可拓展:三只动物抽到卡片后最多能组成21、31、32那谁可以和聪聪一起坐呀?小猫很幸运,他抽到了2和3,那么他一定会摆出一个……(三)握手小动物们谢谢我们帮他们一起解决了这些数学问题,一定要让老师表示谢意,好谢谢你们。(老师过去和学生握手。分别找几个人握手,让学生观察,每两个人握一次手。)
2.采用比较简便的方法,师生合作完成“数据的收集与整理(强调数据的准确性),学生独立完成“表格的填写”。3.小组内讨论完成“表格的分析”。4.全班进行反馈。(意在培养独立收集、整理数据的能力,核对数据的准确性,并且扩大提问题的参与面,让学生也能启动智慧、享受快乐;及时反馈信息,调整教学目标)四、全课总结1.通过今天的学习,同学们有哪些收获?2.应用延伸。(课本第112页练习二十二第1题)五、布置作业教后反思统计是日常生产生活中常用和实用的工具,因此统计也是小学生必备的能力之一。但是统计的教学较为枯燥无味,教师往往会轻视统计的教学,忽略学生能力方面的培养。在教学统计时,老师要激发学生学习统计的兴趣,创造各种情景,加强学生统计中的动手实践操作训练,同时在实际生活中加以运用,并逐步加大难度和密度,同时也需要知道,统计教学不要过分地浮夸,多给予学生统计的意义,使其明确学习的目的。
(1) 你是用什么方法解方程的?要求学生独立完成。请一位同学在黑板上计算。学生交流:等式的两边同时加上同一个数,等式仍然成立。也就是方程 x-9=15的两边同时加上9,抵消掉等式左边的9,这样等式的左边只剩下x。(2) 你会检验方程的解是否正确吗?指导学生把方程的解代入方程进行检验。2.出示:64页第2题的第2小题。提问:你是根据哪个等量关系列出方程的?(1) 标准体重+超出标准的重量=胖胖的体重(2) 标准体重-低于标准的重量=小明的体重提问:他们标准体重的计算方法有什么不同?学生交流:一个是等式两边同时减去同一个数,一个是等式两边同时加上同一个数。三、拓宽应用。1.解方程:x-5.3=10 75-x=402.65页第4题提问:你是怎样选出各方程的解的?把未知数的值代入方程,看看左右是否相等。3.65页第5题提示学生认真读题,注意选择题中所给出的条件是否有用。
二、教学目标1、知识与技能:使学生经历探索加法交换律的过程,理解并掌握加法交换律,初步感知加法交换律的价值,发展应用意识。2、数学思考:使学生在学习用符号、字母表示加法交换律的过程中,初步发展学生的符号感,逐步提高归纳、推理的抽象思维能力。3、解决问题:运用加法交换律的思想探索其他运算中的交换律。4、情感与态度:使学生在数学活动中获得成功的体验,进一步增强对数学学习的兴趣和信心,初步形成独立思考和探究问题的意识和习惯。三、教学重点:理解并运用加法交换律。四、教学难点:在学生已有知识经验的基础上引导学生归纳出加法交换律。五、教学关键:引导学生运用各种不同的表达方法理解加法交换律的思想。六、教学过程(一)情境,形成问题1、谈话:同学们喜欢运动吗?你最喜欢哪项体育运动?李叔叔是一个自行车旅行爱好者,咱们一起去了解一下李叔叔的情况。1、出示李叔叔骑车旅行的情境图。仔细观察这幅图,你从图上知道哪些信息?
教学目标:1、学生经历体验由具体数到用字母表示数的抽象过程;2、学生能用含有字母的式子表示计算公式;教学重、难点:目标1教学过程:一、引入。1、师:同学们,我们开始上课,先做一个游戏:首先,我说a表示举左手一次,我说b表示举右手一次,我说c表示拍手一次。听好了没有,现在老师说,你们做,好不好?师:abc,acb,bac,bca,cab,cba。师:刚才我们用字母表示一个信息,其实,在日常生活中,字母可以表示很多东西,今天,我们就一起来研究“用字母表示数”。(板书课题)2、复习数量关系式:(学生读一次)每份数×份数=总数 单价×数量=总价 速度×时间=路程总数÷份数=每份数 总价÷数量=单价 路程÷速度=时间总数÷每份数=份数 总价÷单价=数量 路程÷时间=速度评析:以学生感兴趣的游戏入手,激发学生的学习兴趣,同时复习数量关系式,为学习新知识奠定基础。
1、完成P78“做一做”第二题:读出下面的分数。2、完成P78“做一做”第一题:直接在书上的横线上写出对应的百分数。3、P79练习十九第4题:读出或写出报栏中的百分数。4、“做一做”第四题:学生根据自己的理解,说说分数和百分数在意义上有何不同。四、布置作业练习十九第1~3题。教学追记:本堂课,我从三个层次入手。第一层:联系生活实际引出百分数;第二层:理解百分数的具体含义;第三层:教学百分数的读写。三个层次,思路清晰,教学层次明显。其中,我把教学重点放在理解百分数的具体含义上,并及时与分数做了比较,教学结构较为严谨。2、百分数和分数、小数的互化教学目标:1、使学生理解并掌握百分数和小数互化的方法,能正确地把分数、小数化成百分数或把百分数化成分数、小数。2、在计算、比较,分析、探索百分数和分数、小数互化的规律的过程中,发展学生的抽象概括能力。3、通过探索百分数和分数、小数互化的规律,激发学生的数学探索意识。
l尺子上每相邻的两条长刻度线之间的一大格的长度都是1厘米。师:我们大家现在一起用手比划一下,1厘米多长。互相看一下,计住了吗?闭上眼睛想一想,1厘米有多长。3、认识几厘米师:我们现在知道1厘米有多长了,那3厘米又有多长呢?师:同学们还能在尺子上找到其他3厘米的长度吗?4、用厘米量师:刚才上课时,老师展示的2根线绳,到底哪一根长一点呢?现在,同学们先估计一下这两根线绳各自多长,然后在测量比较一下,好吗?师:结果是哪根线绳长一点呢?能说说你是怎么量的吗?三、知识拓展1、师:老师这里有一把尺子,可是它断了一节,没有刻度“0”,只剩下刻度3到刻度10,那么这把尺子能不能用来量物体的长度啊?同学们能不能帮老师想一想办法,好吗?2、其他测量长度的工具(课件展示)
教后反思本节课给学生创设了良好的活动空间,把学生实际生活中听说过的见到的平均分现象展示给学生看,把生活和数学联系起来,在学生感受“同样多”的基础上概括出什么叫平均分。揭示平均分这一数学知识在生活中的应用,之后突出了学生三次实际操作。第一次,小组同学互相分水果,重视学生分的结果。体会感受“平均分”的含义。第二次,重视分法:15个橘子平均分成5份。体现了学生对物品的不同分法,建立了平均分的概念。第三次,分矿泉水,通过份数变化,观察分的就结果,深刻体会“平均分”,为认识除法积累丰富的知识。为学生营造探索的空间。第二课时:平均分的认识(二)教学内容巩固“平均分”。课本第15页的例题3。教学目标1.巩固“平均分”的概念,知道平均分就是每一份分得结果同样多。
三维目标1.知识与技能(1)让学生经历用7、8、9的乘法口诀求商的过程,掌握用乘法口诀求商的一般方法。(2)使学生会综合应用乘、除法运算解决简单的或稍复杂的实际问题。2.过程与方法在解决问题的过程中,让学生初步尝试运用分析、推理和转化的学习方法。3.情感、态度与价值观让学生在学习中体验到成功的喜悦,增强学生学好数学的信心。重、难点与关键1.重点:使学生熟练应用乘法口诀求商,经历从实际问题中抽象出一个数是另一个数的几倍的数量关系的过程,会用乘法口诀求商的技能解决实际问题。2.难点:应用分析推理将一个数是另一个数的几倍是多少的数量关系转化为一个数里面有几个另一个数的除法含义。3.关键:以解决问题为载体,培养学生的数感。
D、师:通过刚才摸球,你认为我们能摸到黄球吗?(能)一定能摸到黄球吗?(不一定)也就是说我们摸到的可能是黄球,也可能是白球。(板书:可能)3、超级竞猜:出示挂图,学生抢答。(课本105页例1)三、拓展应用1、师:在我们生活中同样有很多事情都可以用这些表示可能性的词语来表述。2、完成例2。(1)出示挂图,小组讨论。(2)组织学生汇报交流、评价,你想说哪一幅图的内容就说哪一幅。3、你还能用这些词来说说生活里的事吗?先和同桌交流,然后组织汇报、评价。4、游戏:在三叠卡片中各选一张,按排列顺序组成一句话,说一说这件事发生的可能性。5、作业:在书上完成108页第1、2题。四、总结全课1、师:今天,我们主要学习了什么内容?2、小结:生活里可能性的事情还有很多很多,有些事情一定会发生,有些事情可能会发生,有些事情不可能会发生。希望同学们做生活中的有心人,找一找生活中的可能性。
