Thefourthperiod（第四课时）PartBLet'stalk&Makeamonster内容分析本课是PEP小学英语三年级起点第二册Unit3第四课时。本课时是在PartA的基础上，继续学习如何描述动物的特征。主要强调动物某一身体部位的特征，使用句式：Ithas...。在Let’stalk部分，继续参观动物园，并描述大象的特征，引出本节课重点句式：Comehere，children.Ithasalongnose.Ithasashorttail.Ithassmalleyesandbigears.同时，需要能够听懂、会说单词：children和tail。Makeamonster是一个手工制作活动。利用身体部位的图片拼出一个monster。学生可以准备一些身体部位的图片，然后做两个小组活动，由一人发出指令，另一人拼出怪物。课时目标知识与能力（1）能够听､说､认读单词“big,small,long,short”。（2）通过观察､谈论Let’stalk板块的图片,能够在PPT和教师的帮助下理解对话大意。（3）能够按照正确的语音､语调及意群朗读对话,并在小组中进行角色表演。（4）能够在情景中区分和运用句型“Ithasa+形容词+单数身体部位.”和“Ithas+形容词+复数身体部位.”。（5）能够通过制作怪兽游戏活动,操练核心句型“Ithas…”。过程与方法首先，通过先叫一个学生上讲台上完成Isayyoudo的活动，再到多个学生上讲台，以直观的方式引入新授单词child及其复数形式children,再借助PPT的呈现,对比鲜明,使学生易于掌握｡其次，以“Ihave+身体部位.”为铺垫,引导学生将已学知识迁移到谈论动物特征上去,自然引出句型“Ithas…”｡利用实物展示,化抽象为具体,借助手势和肢体语言,帮助学生理解单词含义｡并通过问题引导学生观看并讨论动画,培养学生的观察能力和逻辑推理能力｡最后，小组创编对话,将所学知识灵活运用到实际生活中,达到学以致用的目的｡自由会话练习培养学生的听说､认知能力以及语言综合运用的能力｡情感态度价值观,通过“制作怪物”的手工活动，培养学生热爱生活并激发学生对动手操作的兴趣。教学重难点教学重点（1）能够听､说､认读单词“big,small,long,short”｡（2）能够运用句型“Ithas…”描述动物的特征｡教学难点能够在生活中准确熟练地运用本课时句型进行会话和日常交际｡教学准备教学课件、课文录音、视频、单词卡片等。教学媒体选择多媒体，录音。教学活动1.唱歌2.游戏3.观看视频教学过程Step1:Warm-up&Revision&Lead-in1.Greetingtoeachother.2.RevisionandLead-in.(课件出示:PEP三上教材P25和P28Let’sdo)T:Pleasestandup.Let’schantanddotheactions!Step2:Presentation1Learntheword“children”.Theteacherpointstoastudent:Comehere,S1.T：Touchyournose.Closeyoureyes.（Thestudentcomestothefrontanddoeswhattheteachersays.）S1：...（Actwhatheheard）T：Goodjob，boy！Theteacherpointstoanotherstudent:Comehere,S2T：Openyourmouth.Touchyourface.（Thestudentcomestothefrontanddoeswhattheteachersays.）S2：...（Actwhatsheheard）,T：Welldone，girl！Theteacherpointstotwogirlsandthreeboys:Comehere,children.Studentscometothefrontanddowhattheteachersays.T：Shakeyourlegs.Clapyourhands.（Thestudentscometothefrontanddowhattheteachersays.）Ss：...（Actwhattheyheard）T:Verywell,thankyou.(Thentheteacherturnstotheclass,andpointstodifferentstudents.)Sowecansaythatheisachild,sheisachild,andtheyarechildren.Readaftermethreetimes,please.Explaintostudentsthedifferencesbetween“child”and“children”onthePPT.(出示课件)Teachstudentsthewords“child,children”andwritethemdownontheblackboard.2.Lookandsay.T:Hello,children!Lookatme.Ihavetwobigeyesandtwosmallears.Ihaveasmallnoseandabigmouth.Ihavetwoarms,twohandsandtwolegs.Let’stalkabouttheseanimalstogether.Ss:Yes!(1)Showapictureofanelephant.T:Lookattheelephant.Ithasabody.It’svery…?Ss:It’sverybig!T:Yes.Ithasabigbody.Andithastwoeyes.Aretheybig?Ss:No,theyaresmall.T:Ithassmalleyes.Thentheteacherteachthewords“big”and“small”.Thenstudentspointandtrytoread.(2)Showapictureofagiraffe.T:Canyoudescribeit?S1:Ithasfourlegs.T:Aretheyshortorlong?(Theteachermakesthegesture.)Ss:Long!T:Great!Andithasalongneck,butwhataboutthetail?(Pointtothetail.)Ss:Short!Ithasashorttail.Thentheteacherteachthewords“long,short,tail”.Thenstudentspointandtrytoreadafterteacher.3.Watchanddo.(1)Watchandanswer.Putthepictureof“Let’stalk”onPPT.Letstudentswatchitcarefully.(课件出示：教材第27页Let’stalk的图片。)T:Lookatthechildren.Whoisatthezoo?,Ss：MissWhite，John，ChenJieandMike.T：Right！Doyouknowwhattheyaretalkingabout?Ss:Theyaretalkingabouttheelephant.(2)Watchandthink.(课件出示：教材第27页Let’stalk的视频。)Playthecartoonforthefirsttime,thenaskstudentssomequestions.Letstudentsthinktheanswers.Q1：WhatdoesJohnsayabouttheelephant？Q2：WhatdoesChenJiesayabouttheelephant？Q3：WhatdoesMikesayabouttheelephant？4.Readandact.(1)Studentstrytoreadaftertherecordingandpayattentiontothepronunciationandtheintonation.(出示课件：播放P27Let’stalk的录音。)(2)Askstudentstopracticethedialogueingroups.(3)Actitoutingroups.Step3:Practice1.Guessinggame.Showsomepicturesofanimalsthatarecovered.(出示课件)Letstudentsaccordingtothedescriptionandhaveaguesswhattheanimalis.2.Makesentencesbyyourselves.Letstudentsmaketheirowndialogueswithanimalsinpairs,thenactout.GiveanexampleonthePPT.Makeamodel：S1：Lookatthepanda.S2：Wow，itisbig.Andit’sblackandwhite.S1：Youareright.Step4:Consolidation&ExtensionMakeyourmonster.Putsomepicturesaboutthepartsoftheanimals’bodyonthetable.Onestudentdescribestheappearanceofthemonsterbyusingthesentence:Ithasa(n)…Theotherstudentpiecestogetheramonsterinthewayofjigsawaccordingtowhatthestudentsays.S1:Ithasabigbody.S2:OK.Here’sabigbody.…S1&S2:Oh,hereisourmonster.Showittotheclass.,板书设计Unit3AtthezooPartBLet'stalk&Makeamonsterchild——children（复数形式）Ithas...（smalleyeslongnosebigearsshorttail）作业设计1.Practicereadingthedialogue.（读三遍今日所学的对话。）教学反思1.借助TPR教学法,调动学生的多种感官参与,充分发挥学生的主体作用,激发学生的学习兴趣｡2.重视培养学生整体感知内容的能力,树立较强的全局意识｡3.教学目标明确,教学重难点把握准确｡整个教学过程重点突出,讲练结合,注重实效｡4.教学方法灵活得当,活动面向全体学生,具有广泛性､有效性和可参与性｡
