课后小结
本堂课的教学内容选自PEP小学英语教材四年级上册Unit 6 Part A Let’s learn 和 Let’s do。通过本课时的学习，要求学生能够熟练掌握四个新授单词：long ,short,big,small。在此基础上要求学生能够听懂Let’s do中的指令性语言，并做出相应的动作。本课的教学重点是四个单词的理解和掌握，以及让学生用句子“It’s big/small/long/short. It has a long/short tail”对相应的人或物的大小长短做出正确的描述。
为了达到以上教学目标，我把课堂分成两部分：long/short的学习以及，big 和small的学习。按照整体设计思路：实物呈现——操练——情景操练——表演——chant的过程，首先通过动物图片引出兔子玩偶，两个大小不同的兔子引出big 和small。并通过实物兔子玩偶引导学生用I have a rabbit,it’s big/small.让学生在句子中操练新词。运用角色扮演，让更多的学生在情景中运用句子，达到操练的目的。让学生在chant节奏鲜明的音乐中，听，说，做相结合。从呈现到操练，步步递进，让学生在高密度的操练中掌握新知。
