教学反思：
一、教学内容和重点：本节课的复习内容是数词和口语训练, 通过对基数词以及序数词的构成和用法的复习,达到让学生能够熟练掌握和运用数词的教学目的, 并且选择口语材料时有意识地选了一篇数字较多的Passage26, 以便检查学生在碰到短文中的数字时是否能流利地读出来。
二、具体教学环节做了如下安排：（1）教学前的热身与铺垫：通过学生比较熟悉的儿歌《数鸭子》引出本课复习内容。（2）复习时先呈现一些容易出错的数词，如：four-fourteen-forty; eight-eighteen-eighty; nine-ninth-nineteenth-ninetieth等，然后再让学生做一些习题，最后让他们总结出使用数词时需要注意的规则、重点。数词复习后用一篇朗读短文和一个话题来检查学生在口语中碰到数字时是否能脱口而出。
三、总体效果：上课流程清晰，结构合理，过渡自然。能够按照预设的教学目标，完成教学任务。学生参与热情高，课堂气氛较为活跃。学生的口头和笔头能力都得到了训练，取得了较好的教学效果。
四、需要改进的环节：校对答案时应该有针对性地选择学生易错的评讲，而不应该逐个讲解, 以致于后面觉得有点赶.
五、小结：通过开设这节市级公开课，让我明白课前充分备课、精心设计教学流程，是上好一节课的前提。同时从蒋老师和听课教师那里学到了很多教学建议和方法，他们让我收获了宝贵的教学经验，能让我在以后的教学上路走得更远。
我希望以后能更加精心备课，让我的课堂变得生动精彩，取得更好的教学效果
