六年级英语下册第一单元第一课时教学设计
一、教学目标
1.能听、说、读、写taller、longer、older、younger 、shorter，than单词，发音准确。
2.能够在情景中恰当运用句型How tall are you? I’m1.61meters. I’m taller. You’re taller than me.
3.能够运用新学的内容完成 “Do a survey and report”任务.
4.能在课堂的活动中运用所学的语言进行交际。
二、教学重点： 能听、说、认读taller、longer、older、younger 、shorter单词，发音准确。
三、教学难点： 能读准than并能运用比较级的句型。
四、设计思路 利用大家都非常熟悉的名人刘翔和姚明引入新单词taller和shorter的学习，形象直观，便于学生接受。而在学习younger和older的时候，则直接用教师和学生的实际年龄做为教学资源，让学生在实际生活中学习新知识。Chant是小学生学习英语时最喜欢的练习方式，在学习新知时，用chant 加深学生的印象，便他们牢固掌握新学单词。
五、教具准备 教师准备教学过程中所需的挂图、单词卡片和光盘。
六、教学过程
