Part B Let's learn & Let’s do
内容分析
本课是PEP小学英语三年级起点第二册Unit3第五课时。在本课时中，John
和Chen Jie继续参观动物园。他们看到了鸵鸟，并描述它的样子，由此引出重点词汇：small，big，short，long。这四个词汇要求学生会认读。Let’s do 和A部分的Let’s do相似，是个与身体部分与形容相关的指令性活动。主要内容是把眼睛睁大，眯小，把胳膊伸长、缩短。在活动中练习本课时的四个重点单词。让学生既对教学内容感兴趣又在多种形式游戏中，快乐地学习、操练，达到预定的教学目标。
课时目标
知识与能力
（1）能够听 说 认读单词“small, big, short, long”。
（2）能够熟练运用上述单词并通过多种活动运用句型“It has…”描述动物的特点。
（3）能够借助大量的肢体活动和思维活动,培养学生的观察能力 思维能力和表演能力。
（4）通过活动能够更好地掌握单词和句型,进一步培养语言交际能力。
过程与方法
首先，先整体呈现动物,再将具有big特征的动物身体部位圈出,给学生以直观的认识,引导学生归纳共有的特点,引导学生用句型“It has…”来讨论动物 通过对比引出“small”,并借助PPT呈现区别,使学生易于接受和掌握
其次，引导学生自己通过观察寻找符合“short”特征的动物身体部位并进行描述,培养学生的观察能力和语言综合运用能力 再用相同的方式，引导学生学习单词“long”,突出学生的主体地位,培养学生的自主学习能力 并通过问题引导学生观看并讨论动画,关注学生的有效参与,借助问题让学生把握教学内容,提取关键信息
最后，做游戏能够很好地调动学生的学习积极性,吸引学生的注意力,让他们在略显紧张的氛围中,强化对单词的记忆 Let’s do活动进一步巩固知识,调动学生多种感官的参与
情感态度价值观
在Let’s do部分，让学生根据所发出的指令做出相应的动作，会激发学生对本节课的学习的热情和兴趣。
