3.情感得到升华“Sharing brings happiness.”

教学过程:

Step1. Lead in

1.利用多媒体播放歌曲“How many boxes?”(两只老虎的配乐)

2.欣赏完歌曲后,老师问:“How many boxes?”学生回答eighteen。

T:I have three boxes here.(老师拿出3个不同颜色的盒子)Whats in the blue box?Come here,touch and guess.先让学生摸并猜一猜,然后数一数有多少个。Eleven rubbers. Thirteen stickers.Fourteen rulers.老师分别送一个给上来数的同学。

I am very happy to share things with you.老师告诉大家自己是分享俱乐部的成员,大家把自己闲置下来的物品带到分享俱乐部,给那些需要的同学。Look,this is my name card.Am I cool?(老师展示挂在胸前的证件)Do you want to join the club.告诉学生要加入分享俱乐部,要完成3件事情。(1)Learn to count.(2)Learn a story (3)Learn to share.

Step 2. Learn to count 完成任务1

1.利用多媒体呈现分享俱乐部成员提供的cap图片,请学生看图回答问题“How many caps?”。

S1:Fifteen.

用PPT呈现另外又有同学捐献了cap,一顶一顶的增加,同时问学生:“How many caps?”请学生一起数1~19.

2.让学生总结13~19的特点。

让学生看这些单词的共同点是什么,发现“十几”的规律。

除了eleven,twelve,thirteen,fifteen,eighteen为特殊形式外,fourteen,sixteen, seventeen,nineteen 都是由个位数+teen构成。

Step 3. Learn a story 完成任务2

T:You have learned to count.Now lets learn a story about numbers.

1.观察图片,说说信息。

T:Look at the pictures.Who are they?Where are they?

S:They are Mike,Helen,Liu Tao and Yang Ling.They are at Mike and Helens home.

2.无声动画,视觉领先。

看完无声动画后,给出图片帮助,让学生来数一数共有多少玩具车,和贴纸。

S:Thirteen cars.Fifteen stickers.

3.发挥想象,预测对话。

T:Look at the pictures and try to guess what they are talking about.

T:Mike is pointing at his toy cars.What does he say?

S:Look at my toy cars./I have many toy cars./Look here…

T:Great!Excellent. Look at Liu Tao,Hes surprised.What does he say?

S:How nice!/Great.How many toy cars do you have?/ So many toy cars!

T:How many?Ss:Thirteen.

在学生看完一遍无声动画,对故事内容有了一个视觉印象后,在此基础上,让他们一幅幅地看着图画,自己观察图画,猜测他们的谈话内容。学生的答案可以与书中一样,正是这样才能锻炼学生的思维能力和口语表达能力。顺势引导学生说说Yang Ling 和 Helen 的感受,渗透情感教育,让学生理解分享可以带来快乐。

4.有声动画,还原课文。

T:You did a great job in guessing their dialogues.This time lets watch the cartoon carefully to see what they are saying indeed.

【设计意图:在学生进行充分的猜测之后,让他们观看有声音的动画,这种设计主要是让学生对课文内容有更深刻的记忆,方便学生理解课文。】

5.跟读故事,注意语音。

6.集体朗读,注意感情。

2.拿出自己所带物品,编对话,老师先和一位优秀的同学编对话,做示范。

3.学生两人一组,拿出自己所带的物品,根据投影上的句子提示,与同桌编对话。
