Module4Unit1Task:listeningforstatisticsanddescriptions教学设计:湘潭市二中彭喜梅审稿:湘潭市教科院陈红语言材料分析:每个task板块都通过提供一系列活动来提高学生的听说读写的综合技能。它含有三个步骤。其中步骤1通常是给学生一个明确的任务,让学生通过听和读的渠道来培养获取信息的能力。本单元的Skillsbuilding1旨在通过使学生学会怎么听数据和数据描述,来进一步提高学生的听力。在复习了解包括分数、小数和百分数等数据的表达和描述后,要求学生完成五段有关数据的听力填空,再根据听到的数据完成一个条形图表。整体思路:1、引入:通过谈论巧克力,引出分数、小数和百分数,使学生对数字有初步印象。2、分别讲解分数,小数和百分数的表达和读法,并总结规律。3、帮助学生熟悉常见的数据描述,如增加,减少,趋势和范围等。2和3都是为后面的教学步骤听力做准备。4、听力竞赛:听五段材料,根据所听到的数据填空。(exerciseonpage12)5、听力练习,根据听到的数据完成一个条形图表。(Step1onpage13)6、进一步熟悉数据的描述,根据设计的一个数据表格,谈论数据变化。帮助学生由“听”进一步到“说”。具体操作:Period1I.Teachingaims(Threedemensions):1)Knowledgeandskills:a.Tolearnhowtolistenforfractions,decimalsandpercentagesanddescriptions.b.ToimprovetheSs’abilityoflisteningandspeaking.2)Processandmethods:a.Howtoread,listenforandtalkaboutstatisticsanddescriptions.b.adoptingnewstudymethods:exploration,cooperationandindependentstudy3)Emotions,attitudesandvalues:HelptheSsformagoodhabitoflisteningandbecomemorepatientandcarefulwithstatisticsanddescription.II.TeachingPrinciplesTask-basedTeachingApproachandSituationalTeachingApproach.III.Teachingaids:Multi-meidateachingequipmentIV.TeachingProcedures:Step1GreeingsandleadinGoodmorning,students.Doyoulikechocolate?Howmanyofyoulikechocolate?Oh,aboutahalfoftheclass.That’s50%.(write½and50%ontheBb)NowI’llshowyouapictureofthemostexpensivechoclateintheworld.ItcostsUs$102.50perpound.(write102.50ontheBb)用心爱心专心Todaywearegoingtolistenforfractions,decimals,percentagesanddescriptionsofstatistics.Step2HowtoreadstatisticsTask1A:Howtoreadfractions?½a/onehalf2/3twothirds¾threequarters2½twoandonehalfTips:1.分子用基数词表示,分母用序数词表示.2.当分子大于1时,分母要用复数.B:Howtoreaddecimals?0.3zero/nought)pointthree6.79sixpointsevennineTips:在小数点后,我们要单独读每个数字。GettheSstoreadthedecimalsinthepassage:一块44克重的德芙黑巧克力中含有碳水化合物27.76克,蛋白质1.85克,脂肪13.2克,钙14.08毫克,磷58.08毫克,镁50.6毫克,钾160.60毫克,所以巧克力能够补充人体每天对于多种营养素的需求。C:Howtoreadpercentages?63%sixty-threepercent45.72%forty-fivepointseventwopercentTips:在小数点后,我们要单独读每个数字Step3HowtodescribethechangeofstatisticsTask2Whenlistening,weshouldcareabout:(1)anincreaseanincreaseof(2)adecreaseadecreaseofgoupbydecrease/fallbyincrease/risebydecrease/falltoincrease/riseto(3)nochangenochangefourtimesasmanyremain/staythesame(4)trendsdownward/upwardtrend(5)arange:varybetweenAandBasteadyincrease/decreasefromAtoBstartoffat/endupat(6)anaverage:averageprice/number…riseslowly/gradually/smoothly/sharply(7)alimitthemaximumvolumepeakatfalltothelowestleveldroptothelowestpointShowtheSssomewordsandphrasestodescribethechangeofstatisticsasabove.(Point2onpage12)Explainthemeaningstothem.Step4ListeningTask3Listeningcompetition:ListenforthestatisticsRules:Thewholeclassisdividedintotwoparts:YellowteamandBlueteam.Afterlistening,anyoneoftheteamcanwritetheanswersyouhearontheblackboard.Onepersoneachtime.Theteamwhichge...
