说课
在热身环节，我通过问题引导学生回顾上节课所学的重点词句。在单词学习环节，我让学生通过观察，归纳出英文数字的表达法，引导学生自主学习。接着我设计了“看图片快速说单词”和“猜价格”的游戏，进一步巩固数字以及询问价格的句型，让学生在活动中熟练掌握单词和句型。在歌曲学习环节，我先通过歌曲中营业员的图片引出四个服饰单词，通过谈论物品的价格，让学生感知价格很便宜，引出生词。接着让学生自己听歌曲找出营业员售卖东西的用语，教授新句型。然后让学生自读歌词，全班跟唱和模仿老师的动作齐唱；最后通过改编歌曲让学生更熟练地掌握购物用语，为后面的编对话做好铺垫。在最后的巩固环节，我设计了“比一比谁是最佳营业员”的活动，这样可以激发学生的表演欲望，提高综合语言运用能力。
最后，跟大家分享一下本节课中的几点思考：
关注复习环节与课前课时的衔接
关注游戏是否让每个学生都参与进来
关注学生综合语言运用能力的训练
