Unit 1 How Tall Are You? 教学设计【教材分析】六年级的学生正是好奇心极强的十分感兴趣，这课就是以谈论恐龙开篇的，所以我在课件中多加了几张恐龙动画片，把重点句型和词汇让恐龙说出来。
接着教材又用萨拉询问埃米她穿多大号的鞋，这是学生日常生活中常见的。
【学生分析】我所带的两个六年班，学生整体素强一些，基础薄弱是这两个班学生的共同之处，鉴于这一课开始学习比较级和最高级难度大，我准备这样设计教学环节和教学方法，完全让学生自己操作，多准备几个尺子和小称，亲自测量，把重点句型使用多媒体反复播放。
【教学内容】中心话题：询问身边的人或事物的年龄、身高、重量及长度并做比较。
语言功能：能够运用目标语进行身体或事物高矮、大小、重轻、长短进行描述和问答。

【单元重难点】1.本单元的教学重点是让学生在联系日常生活的对话中运用比较级。
2.本单元的教学难点a. 各类比较级词汇及相应问题的掌握。
b. 比较级不规则变化和写法的掌握。
