Teaching aids 教学准备（含板书设计）教学准备：PPT板书设计：Unit 8 We’re twins !Who’s he/she?Is he/she your father/mother …?Yes, he/she is …No, h e/she is not …说课本节课是Unit 8的最后一课时，教学内容是Checkout time, Sound time and Ticking time 。
主要教学目标是复习本单元核心词汇和表达，帮助学生检验自己的学习成果，学会自我评价和互相评价。
为了达到这些教学目标，我设计了四个板块：在复习板块，通过猜测动物的父母想象他们的对话，复习单元核心句型。
表演创编卡通，介绍Sam 的一家，培养学生小语篇输出能力。
Checkout time 板块，首先引导学生观察图片，讨论Mike 的家庭照片；接着通过书面练习，检测学生掌握情况。
Sound time 板块，引导学生阅读理解，朗读体会发音。
然后，让学生从自己已知的词汇中找到含有n 发音的词，并创编儿歌，激发学生朗读学习发音的兴趣。
Ticking time 将单元复习和评价相结合，教师将每部分的评价标准细化，让学生通过自评和互评的方式进一步巩固这个单元的核心内容。
特别分享： n [n] new nine man 学生找到含有n 发音的单词·发挥学生的创意，用相同发音的单词创编简单的韵律儿歌。
