教学重点和难点
重点: 用句型There are enough.和There aren’t enough. 表达物品数量是否充足。
难点：单词enough和词组give out 的理解与运用。
教学过程
Step 1: Warming up(热身活动)
1. Greetings（日常问候）
2. Review（复习）：Sing a song《How many do you want?》
（设计意图：通过复习，为学习本课句型作铺垫。）
Step 2: Presentation(呈现活动)
1. 利用情境来导出句型：There are enough…
T:How many windows are there in our classroom?
S：There are 4 windows in our classroom.
T: How many doors are there in our classroom?
S：There are 4 doors in our classroom.
T: How many students are there in our class?
S：There are…
T: How many English-books are there in our class?
S：There are…
T: Are there enough?(呈现enough)
S：Yes! There are enough English-books.(教师引导学生回答,并板书)
T: There are…students and …English-books. There are enough English-books for everyone.(呈现everyone)
T: Everyone gets a desk.. There are enough.
T: Look! There are some pencils in my hand. How many pencils are there?
S：There are …
T: Are there enough?
S：No! There aren't enough pencils.
板书：
There are enough chairs.
There aren't enough pencils.
(设计意图：通过情境来导出，学生更容易理解这一句型。)
2.利用游戏来对这一句型进行操练，并导出give out和give …to…
T：Let’s play a game.(抢凳子游戏)
T：I want to play a game with you.Do you like playing games?
(放5张椅子在教室前面，请5位同学上来)
T：I want 5 students to come here. There are 5 chairs here. Are there enough chairs?
Ss:：Yes! There are enough chairs.（引导学生回答）
T：You circle the chairs. When I say “stop”, you must sit on one chair. Other students say“There are enough chairs.” Clear? （提醒学生做游戏的时候要小心：呈现careful）
Ss:：Yes!
T：Who wants to try?
玩了第一轮游戏后：
（搬去一张椅子，5个同学继续玩）
T：There are 4 chairs and 5 students.
T:：Are there enough chairs?
Ss:：No,there aren’t enough chairs.
T：Very good!
游戏结束后：
T：Ok! You all do a good job. I will give out the presents!（呈现give out） T：Give candy to every actor. (把candy分给每一个表演的同学，呈现every) （设计意图：通过游戏来进行操练There are enough.和There aren't enough.激发学生的积极性。通过奖励来导出give out 和give …to…，比较自然合理）
3. 回归课本：
①Let’s go into the text. Open your book and turu to page 18. What did Ms Smart buy yesterday?
Ss：Pencils.
T：Listen to the tape and answer my questions.
T：How many pencils did Ms Smart buy?
S：25.
T：How many children are there in the class?
S：25.
T：So,there are enough pencils for students. But, why dose Sam say“there aren’t enough”?
②Read this paragraph again and find out the answer.
T：How many pencils does Sam get?
S：15.
T：How many pencils are there in the blue box?
S：10
（读一次学生还找不出答案，再读一遍）
③Look at the two pictures. What happened to them? Read this paragraph.
S：…
T：Sam stumbled by John’s bag. And what happened to John’s pencil? S：…
T：Yes, John’s pencil is divided into 2 pencils. Who gets 2 pencils？
S：John gets 2 pencils.
T：Ok! Let’s retell the story.
复述：Ms Smart bought 25 pencils yesterday. She asked Sam to give out the pencils for everyone. There are 25 children in the class. But Sam gets only 15 pencils. There are 10 pencils in the blue box. There are enough pencils for everyone. John’s pencil is divided into 2 pencils. John has got 2 pencils.
（设计意图：课文比较长，通过问题的解决理清故事情节，复述课文内容更进一步理解课文。
Step 3: Practice(操练活动)
1.Read after the tape ,then read this text in roles.
2.模仿朗读课文，表演精彩片段。
Step4 Summery and homework（课堂总结和作业布置）
1.总结
2.Homework
1）读课文
2）活动用书练习
（设计意图：任务作业的布置帮助把课堂所学迁移到新的情景中，促进学生自主学习和自觉完善，进一步巩固运用所学内容）
课堂教学预测
课堂可能出现的问题：在呈现活动中，本课的课文比较难，老师在提问题的时候，学生可能回答不出来，这时老师要注意随机应变，可以通过再次读，来回答。老师要循循善诱，启发学生，引导学生回答。
在游戏这一环节中，学生只顾着玩，老师应给以提醒。
