三年级下册unit 3 Part B Lets learn.doc

Unit 3 Part B Lets learn1. 教学重点：单词big, small, long, short的音、形、义、用；能听懂会说句型It has ,区别使用Its和It has 。2. 教学难点：利用所学形容词熟练自如地描述各种动物。单词small 中 l 的发音，舌头要上卷.Short 的两种意思。三、教法与学法本节课我主要采用了任务型教学法，以make a ostrich为主线任务，引出形容词，操练形容词和句子。同时在和黄老师商量之后，我们提前布置了让孩子们带上自己动物玩偶，让孩子们在巩固扩展环节能够运用所说句子和单词说一说动物。激发他们的兴趣，让他们有兴趣地说，有信心地说。四、教学过程设计本节课的教学设计是按整体部分来设计，总的流程如下：Step: warm up-Presentation-Practice -consolidation-summary and evaluation：首先在warm up 热身环节，我进行了listen and guess的游戏，老师描述动物的外貌特征，孩子们猜动物。主要是为了激活孩子已有知识，激发学习兴趣，为接下来的语言学习做铺垫。在presentation呈现部分，我通过呈现鸵鸟不同的身体部位引出不同的形容词。在Practice操练部分，我通过listen and number, look and match, look and say, lets do几个环节操练单词的音型义用。在consolidation and extension巩固拓展部分，我主要是让孩子用所学句型来描述自己的动物玩偶，或者是PPT上的动物，然后扩展到对人的描述，运用到She/he has这个句型。然后再进行一个写的练习。在summary and evaluation部分我会对本节课星星最多的小组进行表扬及奖励。五：课堂实录：1.
