《Unit 4 At a farm  let’s learn  let’s do》教学设计

李莹

教材内容：PEP小学英语第四册Unit 4 At a farm Part B Let’s learn。本课时将要呈现的是一幅农场图,图中包括本课时要求掌握的重点单词sheep，hen，cow，horse以及句型What are these/those? They are…Are these/those…? Yes, they are.No,they aren’t.目的是让学生通过看图问答巩固所学的动物名词，同时了解并掌握这些单词的复数形式。

1、知识目标：

（1）使学生能听、说、认、读sheep, cow, horse, hen单词。

（2）巩固句型：What are these/those? They are…Are these/those…? Yes, they are.No,they aren’t.等句子,学生能听懂并理解其意思。

2、能力目标：

  (1)能听懂Let’s do中的指令并做出相应动作。

  (2)能灵活运用所学知识进行交流。

3、拓展目标：

句型①.I can …(feed, ride, milk, shear, hold) the sheep/hen/cow/horse/lamb.

②. The sheep/hen/cow/horse can… (give people fur/meat/eggs/milk或carry the things.)

可拓展更多与农场，动物有关的听读材料或视频，让学生在不同的语境中灵活运用。

4、情感目标

（1）培养学生注意观察、认真模仿的良好习惯和主动竞争的竟识。

（2）激发学生学习英语的兴趣，使学生树立学习英语的自信心。  

（3）教育学生“动物是我们的朋友，要爱护动物”。

教学对象是我所带的四年级学生，经过一年级和三年级的共同学习，所以学生对跨越式的教学流程有一定的了解，能够接受和掌握拓展阅读的大部分知识。他们活泼好动，喜欢说唱英文歌谣，但有的学生的主观能动性比较差，受外界影响较大，自控能力差，因此，教师要多关注学生，尤其是后等生。

教学重点：1、掌握农场上常见的动物的名称及其复数的表达形式。

2、句型：What are these/those? They are…Are these/those…? Yes, they are.No,they aren’t.的问答。

教学难点：所学单词的复数形式（尤其要注意sheep的复数、单数形式是一样的）以及复数形式发音。

教师: 课件；所学动物的图片、单词卡（单、复数各一套）；学生奖品若干。

学生：白纸若干

1、Greetings.

2、Revision.

T:  I’m Old Macdonald .I have a big farm. Yesterday we visited my vegetable farm. Let’s go and see again.

T：Are these …?

S1: No, they aren’t.

T: What are these?

S1: They are…

T: How many … can you see?

S1：I can see…

T: Do you like …?

S1:…

T: Work in pairs and show.  此复习说能够高效地带动学生复习上节课的主要知识，快速地进入本课内容，也能增加学生在课堂中练习的时间。

1、T:My farm is so big. So I need an assistant for my animal farm. Do you want to be my assistant?

Ss:  Yes!

T:  But you should finish the three tasks:

1. The names of the animals.

2. What can you do for my animal farm?

3. What can the animals do for people?

T: Are you ready？

Ss:  Yes.

2、Sing an English song :“ Old Macdonald had farm!”

Dear class, Let’s sing an English song. Please，give me your hands and follow me and follow the CAI.(播放课件，展示flash动画，师生一起拍手跟唱歌曲“ Old Macdonald had farm!”。）

T： On the farm I had some animals. Do you know what are they?（学生根据歌曲内容回答问题）

S:  Chicks and ducks.

T: Good job! But there are also had many other animals in it. Let’s go to 。；。-the farm and have a look. Listen to the sound. Guess what they.（听声音，学生根据动物的叫声猜测是什么动物！） are

【设计意图】通过学生听动物的声音，既可以引起学生的有意注意，又可以激发学生们的学习兴趣，完成P41 Let’s play。

①教学hen

T:  What is it? ( 画简笔画，学生们看图可用汉语回答)

S1: 母鸡

T：Yes,（出示单词ten, pen，让学生自己说出“hen”。）Please follow me, please!

Ss: Read it together.（升、降调、小组、个人等形式读单词。）

T：Do you know what is it？（老师在母鸡的后面画一个鸡蛋）Yes, it’s an egg.(然后再画一个)Look, what are they? (学生们已将知道是鸡蛋了,于是便会说是eggs) Yes, good job. They are two eggs. (继续画一个鸡蛋)What are they?

Ss: They are three eggs.

T: Yes, very well. (然后老师一边画另一支母鸡一边问,学生可能仍就感觉是鸡蛋,但最后画的是一只母鸡)What are they?形象生动

Ss: Hens.(学生们根据上面的练习,会很自然的说是hens)

T: (教师鼓励)They are hens.(展示附属母鸡的图片)

How many hens can you see? Do you like hens?

【设计意图】 通过相同音素单词的比较，由学生自己感觉“en”的发音，用以学过的的单词教学新单词会更加容易。同时通过学生们自然的理解记忆,更能进一步加深学生对单词复数的的印象。

②教学cow

T: What is it? Do you know?

S: 牛

T: What is it? It’s black and white.

S: 奶 牛

T：Yes！It’s a cow. ( 左手出示一头牛奶的词卡) Look at these words,(how, now) . How to read?

S：学生用各种形式跟读单词。

T：（右手出示一群奶牛的图片）It’s a cow. And they are cows.

S: 经过教学hens的复数,学生们很自然的感知cow的复数形式是cows。

T：You are so clever.

③教学horse

T: Listen！Who is coming? (播放课件马的声音，学生们都可以猜出是马)Who can draw it on the blackboard。

S: （学生画马）

T：Is he/she right？

S:  Yes！

T: （教师展示一匹马的课件）Yes，is a horse. Look at my mouth and Follow me.（强调o的发音圆唇不变化）Who can try? (Ask students to read out the word。 )

Ss: Read it together, this line, one by one，

T：（点击课件，出现了两匹马）Look，What are these?

S: They are horses. (重点强调horses的发音) 操练单词。

④教学sheep

T: It has two horns. Its wool is long. What is it?

S: 绵羊

T：Yes, It’s a sheep.(出示绵羊的词卡)Follow me. “sh”—“∫” “ee”—“i:” “sheep” Who can try? (Ask students to read out the word )

Ss: Read it together, one by one group and group.

T：（点击课件，出现了三只绵羊）What are they?

Ss: They are sheeps.（学生可能根据以前的规律说出sheep的复数是sheeps，所以教师纠正：sheep的单复数形式一样）

⑤教学goat

T: Look, (教师边画边说边做动作)It has beard and two horns. It likes climbing mountains. What is it?

S: 山羊。

T：Yes, we can see a goat.(出示山羊的图片)Look at my mouth. Follow me. Who can try?

 Ss: Read it group by group, one by one and so on。

⑥教学lamb

T: Please look at the CAI. It’s the mother goat and it’s the father goat。Do you know what is it？  (教师出示CAI，展示羊爸爸羊妈妈的图片，最后由学生猜测？表示的是什么？)

Ss：小羊。

T：Who can draw it on the blackboard？

S：学生上台来画小羊的图片。

T：Is he/she right？

S:  Yes！

S:（个别学生操练）（生降调操练）

T: One lamb, two lambs, three lambs. Look, they are lambs. (出示许多小羊羔的图片,教学单词复数。)

2.Let’s do:

T: Now, let’s go to the farm and help me to do something. (播放课件Let’s do部分音乐，师生一起做动作)
