《Unit5 There is a big bed Part A Let’s spell》教学设计广水市骆店镇草店中心小学李芬课题：Unit5 There is a big bed? Part A Let’s spell课型：讲授课教学内容分析：这是一节典型的语音教学课，主要是让学生通过听例词发音，观察例词结构中共有的特征，学习ai/ay在单词中的发音规律，强化学生对语音的感知意识。
通过看图，听录音，写单词活动培养学生听、说、读、写单词的能力。
教材对象分析：小学五年级学生活泼好动，课堂上注意力很难长时间集中在同一件事情上，他们对图片、实物和具体的教具感兴趣，大多数学生上课时能积极参与到英语学习中来。
但对于枯燥的语音知识，要马上让学生进入学习状态，抓住语音发音规律还是有一定的难度，教师应予以方法上的指导。
教学目标:1.知识与技能目标：1).学生能够感知并归纳字母组合ai 和ay在单词中的发音规则。
2).学生能够读出符合ai 和ay发音规则的单词。
3).学生能够根据单词的读音拼写出符合ai 和ay发音规则的单词，补全短语和句子。
2. 过程与方法目标：1).引导学生自主拼读新单词，通过见词造句的活动引导学生在生活中真实表达。
2).运用色彩鲜艳的图片理解记忆本课中单词，如 wait, paint, rainbow等词。

3.情感态度与价值观目标：1).通过句子的的操练培养学生主动思维，乐于模仿，积极开口的英语学习态度。
2).通过小组合作和小组竞赛的学习和评价方式帮助学生树立合作意识和竞争意识，体验成功，获得自信。
3).通过吟唱歌谣，化了学生对句子连读、重读和语调的意识，培养学生的英语语感，增强了英语学习的自信心。
