                         专题四:低年级第二课时(PEP 三下)
                             Unit 6 At the Zoo Part B Let's talk
                                                     临沂第一实验小学  卢英苗
一、教学目标:
1. 能力目标:
让学生围绕“at the zoo”这个主题进行“谈论动物”的活动,让学生了解到更多动物的名称并能对动物的主要特征(高矮、大小、习性等)进行简单的描述。培养学生听、说、认读和对话交际的能力,及培养学生小组合作学习的能力。
2. 知识目标:
(1) 能听懂、会说一些含有简单形容词的句子,并能在实际情景中用相关
       形容词来描述动物的特征。e.g. The giraffe is tall . The deer is short. 
        It is (so)      . It has (a long tail).
(2)学习了解常用表达法:Yeah. You are right .You see.
3. 德育目标:培养学生爱护动物、保护动物的意识。并了解Don’t feed the animals in the zoo.
二、教学重点,难点:
     抓住动物特征,用含有简单形容词的句子来进行描述。
三、教学用具:
   自制的各种小动物图片及4个盘子、一颗大树的图片、四张装饰成动物园的吹塑纸板、(动物园名称:Happy zoo, Lucky    zoo, Funny zoo, Sunny zoo. )
图钉、动物园门、录音机、Amy and her dad's picture
四、学情分析
本节课是在学生学完B Let’s learn的基础上学习的一节对话课,教学对象是小学三年级学生。学生已经学过一些简单、常见的动物单词,如dog、cat、monkey等。另外学生已学习了一些形容词,如:big, small, long, funny 等。
五、教学过程:
Step 1.Warm-up 
课件1:封面的背景及音乐《Little and big.》
1. Let’s sing a song. <They Are in the Zoo>
T: Boys and gils. Before class let’s sing a song. Please watch the screen. Clap your hands.
课件2:歌曲视频 :PEP三下U6 B Let's sing
2. Free talk
T: (教师手指屏幕画面)Boys and girls. Do you like animals?
Ss: Yes.
T: What animals do you like best? Can you tell me?
S1: I like _____.
T: What about you?
S2: I like ___.
T: What animal do you like?
S3: I like … 
T: I have many pictures of animals here.(教师将盛动物的四个盘子分给各小组)In this class, if you can answer my question. You can get one of them from the plate. Let’s see which group can get the most animals. OK?
(设计思路:以歌曲《They Are in the Zoo.》开始,把学生带入本节课的主题: At the zoo. 然后沿着歌曲的思路,在free talk中与学生谈论自己喜欢的动物,调动学生思维,引入对动物名称的复习,学生通过brainstorm活动,绕有兴趣的在不知不觉中进入所涉及到的话题。并借助话题把学生分成四个小组,引入本节课的评价机制。)
3. Brainstorm  复习形容词。
T: We all like abimals. Now, let’s go to the zoo and see the animals. Please watch carefully.
T: Look. The_____is _____. Look at the ____. It's ____.
课件3:动物园的门打开,六种动物图片: giraffe, deer, elephant, mouse, snake, monkey依次出示在屏幕上。
T: Now, let’s chant. 课件4:let’s chant. 句子+动物图片。
let’s chant.
Tall, tall, tall! The giraffe is tall.
Short, short, short! The deer is short.
Big, big, big! The pig is big.
Small, small, small! The mouse is small.
Long, long, long! The snake is long.
Funny, funny, funny, The monkey is funny.
(设计思路:这些动物所选择的都是特征明显的动物,目的是为形容词复习做好铺垫。通过形体语言,帮助学生复习、理解、巩固形容词,)
Step 2. Presentation   
(一)导入呈现
1. rabbit and monkey的对比教学引出long, short的复习。
a. 兔子(教具兔子贴在黑板上面)
T: The animals are lovely. I have another animal. Look, what's this?
Ss: rabbit.
  T: Look at the rabbit. It’s pink. What’s it like? It has a ---. (师用手摸兔子尾巴)
S: It has a short tail.(板书: short)
 T: Yeah. You’re right. It has a short tail. You can get a picture of animal from the plate. (教师用You're right来表扬,并且告诉学生拿奖品:小动物)
b. 猴子(教具猴子贴在黑板上面)
T: Look, what's this?
Ss: monkey.
  T: Look at the monkey. What colour is it? What’s it like? (师用手摸猴子尾巴)
S: It’s orange? It has a long tail.(板书: long )
 T: Yeah. You’re right. It has a long tail. You can get a picture of animal from the plate.
c. 对比(教师手指板书对比)
T: Boys and girls. Look at the blackboard. You see. The rabbit has a short tail .The monkey has a long tail.
d. Ask the students to repeat the sentences. (1-2学生重复读句子)
T: Who can say?
S: You see. The rabbit has a short tail .The monkey has a long tail.
(设计思路:通过rabbit 和monkey的对比,引出long .short 的复习,并引出You see .同时渗透You're right.)
2.pig and squirrel的对比教学引出big, small的复习.
a. 小猪(师将教具小猪贴在黑板上,用手指外形)
T: Look at the pig.
Ss &S: It’s big. (板书: It’s big. )
 T: Yes. It’s so big. You can get a picture of animal.
b. 松鼠(教具松鼠贴在黑板上)
T: Look, what's this?
Ss: Squirrel.
  T: Look at the squirrel. What’s it like? (师用手指小猪和松鼠,对比)
S: It’s so small.(板书: small ) 
 T: You’re right. The squirrel is small. You can get a picture of animal.
c.(教师手指板书对比)
T: You see. The pig is big. The squirrel is small. (也可以此处板书: big ,small)
d. Ask the students to repeat the sentences. (1-2学生重复读句子)
T: Who can say?
S: You see. The pig is big.The squirrel is small.
(设计思路:通过pig 与squirrel 的对比教学,引出big和 small的复习。同时进一步渗透:You see . You're right.)
(设计思路:这一部分的设计,看起来是在复习long 、short 、big 、small这四个形容词,但是它有一个新旧知识点的衔接,那就是人称代词it转换成了具体的名词。本节课中有一个教学重点:The giraffe is tall. The deer is short.其实,这一环节就是重点部分教学的一个铺垫。通过新课导入这一环节,板书句型:It’s (so)---.)
(二)、创设情景,呈现并教学课文。
1. 听录音,回答问题,初步了解课文内容。    
T: Today, Amy and her dad(拿两人图片贴在黑板上) are in the zoo(贴动物园门,画上栅栏。) They are watching the animals. Open your books and turn to P 63. Let’s watch the video and think about the question.What animal are they talking about?
课件5:问题,视频,回答。
Answer the question.
What animals are they talking about? (他们在谈论什么动物)
后出示答案: giraffe 和deer图。
S: Giraffe / Deer.
(设计思路:创设情景,画上栅栏,贴上动物园的门和人物Amy and her dad的图片。通过老师的一句话就把地点、人物、事情交待清楚了,并且借助图片,孩子一目了然,紧接着提出问题:Which animals are they talking about?让孩子带着问题听录音,为课文的理解做好铺垫。)
2. 呈现Picture 1的对话,教读giraffe and tall.  
 随着学生的回答,把giraffe 和deer图片贴在黑板上。
T: Look at the giraffe. (板书Look at the giraffe并领读,将音节分开来读,强调f的发音,加手势帮生理解重读音节。)
T: 教师指板书:Look at the giraffe. It’s so tall. 领读前面板书的单词:small(强调字母组合all的读音),(紧接着板书:tall)
T: Your group. Please show us your giraffe. You can say: Look at the giraffe.
Ss(各组): Look at the giraffe.  
Ss(其他组):It's so tall.
(设计思路:对于giraffe这个单词,它的正确读音仍是本节课的难点。在教学时,先把它的音节分开来教,然后借助手势让学生把握重读音节,从而进一步掌握它的正确读音,然后分组展示giraffe , 自然操练Picture 1 的内容,其他小组运用It’s so tall.来评价,四个小组依次进行,让每一位孩子都开口,扩大训练面。)
3. 教读:deer 呈现Picture 2的对话
T: Look at the deer. (教师指黑板书上的deer图片) (板书: deer)
Ss: It’s short.
T: "eer" is pronounced as "ear" Who can read the word?
S: Deer.
T: Your group. Show me your deer.
Ss(各组):Look at the deer.  
Ss(其他组):It's so short.
4. 展现Picture3的对话
(指giraffe and deer.通过身高对比,引出Picture3的对话)

 

 

 

 

 

 

T: You see. The giraffe is tall .The deer is short. (领读)
T: Who can come here and say the sentences?
(生上台指着描述,引出Picture4,教师用You're right. 或Perfect. Good. Yeah. Yes. 及时表扬)
5. Picture 4 教学
(师生对比,生生对比身高)
T: Please wait a minute. You see. I'm tall. You're short. Ask: Am I right? You can say : You're tall. I'm short.
(师生对比时,师可蹲下让生说:I'm tall. You're short.)
(设计思路:在对话教学中,所涉及到的本单元的单词仍采用“以旧带新”的教学方法。如:通过small和tall总结字母组合all的发音,对比ear和eer的发音,这样可以使学生尽快掌握拼读规则,从而掌握正确的学习方法。课文导入时,巧妙设计问题,这个问题是理解课文的关键,解决问题的过程其实也是对话呈现的过程。由giraffe引出第一幅图画,老师手指图画说:Look at the giraffe. It’s so tall.通过小组展示,体现语言的交流,信息的传达。由deer 引出第二幅图画的内容。giraffe 和 deer教完之后,黑板上的图画很清晰,对比也很鲜明,这时,老师手指板书对比两个动物,自然展示第三幅图画的内容:You see. The giraffe is tall. The deer is short. 在第三幅图画的练习中,让学生上前面指着板书来说,即降低了学生表达的难度,同时引出第四幅图画:师生身高的比较,师生站在一起,老师说:I’m tall. You’re short.引导学生说:I’m short. You’re tall.如果说得正确,师生同时用 You’re right.来表扬。将对话教学设计在一定的语境中,使学生发自内心的理解新知识,丰富并拓展已经形成的知识体系。)
Step3 Practice
1.Listen and repeat.
  T: Please look at your book. Read after the tape. 
2.Practise in pairs.
  T: Please read in pairs.
3.Act out the dialogue.(借助板书,可降低难度)
  T: Who can come here and act out the dilogue.
说明:板书如下图:(这是以前讲课的板书,本节课内容有所变动,所以小动物有所更换)

 

 

 

 

 


 (设计思路:学生通过听录音,分角色读对话,表演对话等形式进一步理解对话内容,并借助板书降低对话表演的难度。)
Step4 Consolidation and extension
1.总结板书,教师描述动物园
T: Boys and girls, look at the zoo. We can say :
   Look at the____.
                   long
      It is so)               short     
     The giraffe/___ is  big 
                                   small
                                   tall 
(设计思路:及时总结、归纳、使知识系统化、条理化,并借助板书介绍动物园,同时为后面学生描述动物园做好示范。)
2. 总结各组的表现,布置动物园。
T: Boys and girls, you have got some pictures of animal in this class. Put them in your zoo. Like this.(教师拿纸板示范,然后将纸板发到各组。)
T: Happy zoo, Lucky zoo, Funny zoo and Sunny zoo
T: How many animals have you got? Please count. One, two, three,----
Ss: One, two, three,---- 
T: How many animals have you got? 
Ss: (各小组组长汇报所得动物数量)
T: 教师随机表扬。
(设计思路:既是本节课的一个课堂教学的评价,也为后面语言的输出创设语言场景。)
3. Practise in groups. 3分钟。
T: Please talk about the animals in your zoo. Use the sentenses. (手指屏幕)
Please help each other.
课件6: 提示语言
Let’s say.
Look. This is ____ ( Happy, Lucky, Funny, Sunny ) Zoo.
Look at the ______. It’s _____ . ( red, yellow, brown---)
It’s (so)____. ( big, small, long, short, funny---)
The _______ is _____. ( big, small, long, short, funny---) 
It has _______. 
(设计思路:先让学生用所学语言进行充分的讨论,抓住动物的特征,然后用合适的语言来描述,培养学生仔细观察的能力和小组合作学习的能力。鼓励学生相互帮助,相互学习,使每位学生至少能够用今天所学的语言介绍1-2种动物。)
4. 各组汇报。
 T: Boys and girl, please stop. Who wants to stand up and show us your zoo? Happy Zoo. Please stand up. Introduce your zoo one by one. 
(全体学生每人能够介绍1-2种动物。可以重复动物名称,但是描述动物特征尽量用不同词语。)
T: Look at the elephant. It's so big. It has a long nose and a short tail.(老师示范一组)
S1: Look at the rabbit. It has long ears .
S2:Look at the squirrel. It has a big tail .
(学生介绍时边指图边介绍)
说明:各组展示的动物园如图:(下图为以前讲课时其中一个小组布置的动物园,这次动物园的名称有所变动。)

 

 

 

 

 

 

 


(设计思路:让每一位学生都有机会表达自己,可以描述相同的动物,也可以重复别人的话。为学生创设自主学习、亲身实践、合作交流的良好氛围,使学生有更多的机会和更好的愿望与他人讨论和交流。鼓励学生运用已有的语言,积极参与语言实践活动,在活动中开拓思维,畅所欲言,积极体验,从而提高语言的运用和表达能力。为学生输出语言创设一个宽松的环境,降低学习难度,激发学生兴趣。)
5. 德育渗透。
T: Boys and girls. The animals are lovely. They are our friends. We should protect them.When we are in the the zoo, don't feed the animals. Please remember. OK?
课件7:在动物园背景下出现:Don't feed the animals.  
(设计思路:在学生描述完小动物之后,通过教师总结,自然引出Don’t feed the animals in the zoo.这一德育目标。)
Step5 Homework
T: Today’s homework.
1. Listen and repeat the dialogue.  (听录音,跟读对话)
2. Exchange your zoo and talk about the animals after class. (课下交换动物园并进行讨论)
课件8:Homework:
T: Boys and girls. In this class, you all did a good job. You’re great.
hank you very much. Good bye, boys and girls.
