教学设计
教学目标
语言知识目标：
1)
掌握下列词汇：eleven，twelve，thirteen，fifteen，eighteen，twenty，thirty
2)
继续练习“询问价格”，
并学习运用数字ten~thirty-one来表达价钱。
3）学会如何作简单的价格报告。
4）阅读服装商店的促销广告，并能获得其服装的价格等相关信息。
2.
情感态度价值观目标：
日常生活中，人们去买东西之前，一般要阅读广告，从广告中获取该商品的一些有用信息，包括价格、性能等。所以给学生提供有些商品的广告或让学生去商店去阅读一些商品的广告，从中获取商品的价格，即可以锻炼学生的阅读能力，又能提高实践能力。本课时的话题贴近学生们的实际生活，便于调动学生们学习的积极性，并从中获得学习英语的乐趣。
