1、四年级上册 Unit7 How much?(Story time) 微型教学设计一、课时分析本单元课文呈现了以爱心义卖为场景的购物活动。Story time这个板块中呈现的是校园义卖活动，Su Hai和Su Yang在卖鞋子、袜子、扇子和雨伞，Liu Tao,Yang Ling和Mike先后买走了这些物品，从而引出How much is it/are they?以及应答Its/Theyre yuan.等语言知识。此教学设计旨在为本课时的新单词和句型的教学片断。二、学情分析学生在三年级下册和四年级上册已经学过了数字119，一些服装类的词汇及点餐用语，这给开展本环节中的活动大大降低了难度。但是，部

2、分学生在日常生活中还不能自然流利地运用所学语言。三、教学目标1.通过数字游戏，复习三年级数字单词，学生能够利用数字表达价钱。2.情境呈现顾客营业员买卖过程，学生能够读准单词：fan，socks，shoes,umbrella，yuan,twenty ,twenty-eight,thirty,forty,fifty,well done,并理解句型How much is it/are they?

Now lets count

4、 together.S:One,two,threenineteen. T:Well done! （设计意图：利用和数字有关的日常用语热身，使学生很快进入英语课堂学习氛围之中，也为下面数字的学习做铺垫，同时教师在学生回答过问题后，给予表扬Well done!很巧妙地学习了新词汇，。）Step2:Presentation and practice:1.learn the numbers:twenty, twenty-eight, thirty, forty, fiftyT:Whats next?S:20T:Yes,its twenty. （ppt出示:twenty）T;Can you read t

5、hese numbers?(21,22,28,29)Ss:twenty-one,twenty-two,twenty-eight,twenty-nineT:Look!

Play a game:Say the numbers Rules:When you see the numbers,say it out and shoot it.（设计意图：利用数学中的加法运算进行thirty, forty, fifty的教学，并利用游戏再次巩固所学数字，既调动了学生的激情，又让学生很好地操练

7、了数字。）2.learn:How much? .yuan.T:Look at this note .Can you say how much?

10、ocks 35, 2 only)（设计意图：利用游戏复习三年级学习过的服装类词汇，并在游戏中通过图片学习新单socks,shoes,然后通过让学生通过猜一猜物品的价格，使他们在直观中的图片中学习了生词only和句型How much is it/are they?并能区分单复数的区别。）4.Work in pairs两人一组，运用身边物品对话A:Can I help you?B:Id like.A:Anything else?B: .A: How much is/ are they?B:Its/Theyre.A:Here you are.B:Thank you.（设计意图：让学生能在模拟的情境中

Selling things)Ss: Selling thingsT:Yes,they are selling things at the charity sale.T:Whats on the table?Ss:a box, a fan, an umbrella, shoes, socks教授a fan,a

12、n umbrella（设计意图：将单词的教学穿插在语篇课文的教学中，而不是将所以的单词集中在一起教学，那样教学很单一，学生学起来会觉得枯燥。）七、板书设计 Unit 7 How much？ How much is it/are they? Its / Theyre yuan.shoes twenty-eight yuan socks twenty a fan thirty an umbrella forty Well done! Fifty八 、教学反思 大多数老师在进行语篇教学时，往往都是将其中的生词和重点句型先集中在一起教学，然后再进行文本的教学，那样的学习学生会觉得方法太单一，学生只是很被动的去接受知识，所以我在设计这课的新单词和句型的教学时，是将新单词和句型穿插在课前的热身环节，数字的运算，游戏的展示及文本的学习中，这样既给学生创设的语境，同时又能让学生在不知不觉中学习了新知，并通过小操练，学生能运用所学知识进行顾客和营业员之间的买卖过程。
