   Step 1 Warming- up

   Ss: Hi, Miss Li

   T: How are you today?

   Ss: Fine, thank you. And you?

   T: I'm fine, too.

   2、Sing a song <Twenty Green Bottles>

   3、Revision

   课件出示:球星姚明、王治郅、纳什、安东尼的照片。

   T: Who's he?

   S: He's Yao Ming

   T: Can you guess which number on his vest?

   S1: It's twelve, I thank.

   T: Sorry you are wrong.(教师摇头表示否定,并通过手势up down提示学生)

   S2: Thirteen

   T: That's right.(让猜对的学生作小老师,带领大家读这个数字。)

   (评析:让学生猜一猜自己喜欢的体育明星的球衣号码,极大的激发了学生的兴趣,避免了枯燥的数字训练,同时渗透句型Sorry,you are wrong. That's right.)

   Step 2 Presentation and practice

   1、Learn word "plus"

   T: Boys and girls, please show me you number cards.

   T: Hello,what's your number?

   S1:It's eleven.

   T:Hello,eleven. Who is he?

   S1:He is 'twelve'.

   T: Is he you friend?

   S1:Yes he is.

   T:Who's you friend? Can you tell me?

   S2 S3 S4..: eight, sixteen,twenty...is my friend.

   教师将加号的卡片戴到头上。

   T: My name is "plus".(板书:plus并用红笔在单词下面写一个加号)

   T: Hello, "one".

   S: Hello, "plus"

   T: Hello, 'thirteen'.

   S: Hello 'plus'. (教师依次和其他的学生打招呼。)

   (评析:将抽象的单词拟人化、形象化,拉近了学生与单词之间的距离,消除了陌生感。)

   2、Learn sentences "What's ...plus .... ? It' s ...."、 "That's right./Sorry, you are wrong."

   T: I'm "plus". But I have no friends. Who want to be my friends?

   (教师请两位学生到台前做朋友)

   T: Look, I have two friends. They are five and ten.(板书:five plus ten)

   教师带领学生读,指名学生读。(教师在黑板上写上5+10=)

   T: What's five plus ten? It's...(示意学生回答)

   S: It's fifteen.

   T: That's right.(用红色的粉笔板书)

   (评析:由于What's five plus ten?较长,先通过为plus找朋友的游戏,让学生先学会句子的后半部分five plus ten,接着再学习全句,从而降低了难度,易于学生理解。)

   教师出示题目:

   (1)、Read talk and mach.

   What's six plus eight ? It's seventeen.

   What's four plus three? It's twenty.

   What's five plus twelve? It's fourteen.

   What's sixteen plus four? It's seven.

   (2)、Listen and answer.

   让两位学生比赛看谁反应快.先由教师说学生答,对答对的学生说That;s right.对答错的学生说Sorry, you wrong.(并用蓝色的粉笔板书,教师领读。)

   四个人一小组进行问答。

   (3)、Say a rhyme

   Plus, plus, plus/ five plus ten / what's five plus ten?/Fifteen, fifteen, it's fifteen./Right, right, that's right.

   Plus, plus, plus/Eight plus six/What's eight plus six?/ Thirteen, thirteen, it's thirteen./Wrong, wrong, sorry you are wrong.

   (评析:1、低年级学生模仿能力强,富有节奏感,用儿歌来巩固所学的单词和句子,效果极佳。2、由于儿歌的内容是对本科所学单词、句型的概括,是本课所学的重点,因此它可以省去老师结束新课时死板的总结。)

   3、Learn word 'minus'

   T:Boys and girls, listen carefully. Let's play s game. If I say 'big', you say 'small'.(教师拿一个大的盒子和一个小的盒子示意学生)

   Andstan, class?

   Ss: Yes.

   T: long

   Ss: short

   T: white

   Ss: black

   .......

   T: plus

   Ss: ....

   教师既是出示单词卡片,领读并板书:minus 在单词的下面用蓝色的粉笔'-'。

   (评析:通过说反义词引出新的单词,学生觉得很新奇,把枯燥的单词变得生动有趣。)

   4、Learn "What's ...minus...? It's..."

   T:Show me your number cards, please.

   Ss: All right.

   T: 'Twenty' and 'seventeen' stand up, please.(分别指两名学生站起来)

   T: What's twenty minus seventeen?

   Ss: It's three.

   T: Where's 'three'? Stand up and show us your number ,please.

   (拿数字3的学生站起来,齐说:It's three.然后老师和其他学生一起说:That's right.)

   (评析:让学生充分利用自制的卡片进行问答交流,培养学生的交际能力,用英语思维的能力。通过交流,学生自制的卡片的到展示,学生有成就感和满足感。)

   Step 3:Consolidation

   1、Listen and repeat

   T: It's time to listen to the tape. First, just listen.(学生看课文,教师先放一边录音。)

   T: Now, listen and reapet.(播放课文录音,学生跟读。)

   2、Play a game.(学生考老师)

   教师用耳塞将耳朵堵起来,让学生给老师出题目,老师只能通过看学生的口型进行回答,如果老师回答对了学生就说:That's right.错了就说:Sorry, you are wrong

   (评析:学生已学习了较长一段时间,已经有些疲倦。此时游戏是做好的放松方法。学生听到要和老师进行比赛,马上又以饱满的热情投入到教学活动中去,将教学活动推向高潮阶段。)

   Step 4: Homework

   1、Listen to the tape. (Part A)

   2、Ask your father or mother:

   What's...plus...?/What's...minus...?

   That's right./ Sorry, you are wrong.

   (评析:把学到的知识向家人展示,让学生体会获得知识的成就感,从而达到学以致用的目的。)

   总评:

本课所学的内容是关于数字的有关句型,相比起其它单元的内容来显得单调、枯燥。但从课堂效果来看,学生兴趣高涨,积极主动参入教学活动,气氛非常活跃。这主要得益于精彩的教学设计:1)、单词拟人化。将枯燥的数字单词变成学生的"名字",相互打招呼问好。拉近了学生与单词之间的距离,消除了陌生感,为句型教学做好铺垫。2)、分解句子,化难为易。将长句子进行分解教学,降低难度,再配上朗朗上口的儿歌,更益于小学生理解接受。3)、精彩的游戏设计。本课的游戏针对性强,易于操作,学生能积极主动的参入。在游戏中学生表现出极大的求知欲和渴望交流的愿望,从而训练了学生的英语思维能力,活跃了课堂气氛。
