教学步骤
一． 问题探究与拓展活动
1.How much和how many的用法区别：how much与how many的意思基本相同，但前者用来修饰不可数名词，也可单独使-用，意思是“多少钱”；后者用来修饰可数名词复数。如：How much are the pants?这裤子多少钱? How much is the book?这本书多少钱?How much bread d0 you want?你要多少面包? How much meat is there on the table?桌子上有多少肉?
How many apples d0 you want?你要多少苹果? How many students are there in your class?你们班有多少学生?
练习设计
用how much和how many完成下列表格。
Ask Answer
l. _______ __________ is the red sweater? It’s $30．
2. ________ _________ are the pants? They’re $50．
3. _________ _________is the T-shirt? _______ $30．
4. How much_______ the green shoes? _______ $60．
5. _________ __________ hats are black?? Two hats．
6. _________ _________ meat do you want? A kilo．
KEY：1．How much 2．How much 3．How much It’s 4．are；They’re 5．How many 6．How much
2．Can I help you?
在讲英语国家的商店里，售货员见到顾客常说“May I help you?”您买东西吗? “Can I help you?” “What can I do for you?”而不说“What do you buy?”因为这样显得无理.
3．基数词10～31的构成。
英语中的数字有简单的记忆方法！
仔细观察，分析，它们是有一定规律的。请按以下三组进行观察分析1)one～twelve；2)thirteen～nineteen：3)twenty～ninety.
1)one～twelve拼写和读音都不同，每个都要记2)thirteen～nineteen这七个单词都以teen为结尾。3)twenty～ninety这七个单词都以ty为结尾。
英语中这些数字，是表示多少的词，统称为基数词.几十几在十位数和个位数之间要使用连字符“-”如：31 thirty—one，98 ninety—eight。
4．袜子、裤子和鞋子的表达方式：在英语中，袜子、裤子和鞋子都用复数形式来表示，但是在表达一双袜子、鞋子或一条裤子时，可运用a pair 0f(一双；一件；一条)词组，当这个短语做主语时，谓语动词用单数形式。如：
The white socks／shoes／pants are$50．那袜子／鞋子／裤子是50美元。
I want a pair of socks／shoes／pants．我想要一双袜子／鞋子(一件裤子)。
The pair of socks／shoes／pants is very cheap．那双袜子／鞋子(那件裤子)很便宜。
二．词意辩析
1．each与every的异同：each与every都可以作形容词用，意思是“每个的；每一的”，一般可以互换，后跟单数可数名词；但each还可以用作代词，单独使用或跟of短语，而every则没有这种用法。如：Each／Every student has a hat．每一名学生都有一顶帽子。We have a hat each．我们每一个人都有一顶帽子。Each of them has a hat．他们每一个人都有一顶帽子。
2．buy与sell的异同：buy的意思是“买”，常用于buy something from…(从……买某物)；sell意思是“卖”，常用于sell something to…(把某物卖给……)。如：I buy a basketball from the store．我从商店里买了一个篮球。He sells the tennis racket to me．他把那只网球拍卖给了我。
三．熟悉课本句型，利用图片，模仿购物
Clerk: Can I help you?
Mary: Yes, please. I want a sweater.
Clerk: What ______ do you want?
Mary: Blue.
Clerk: Here you are.
Mary: is it?
Clerk:20 dollars.
Mary: I’ll take it. .
Clerk: You’re welcome.
四．教室变成商场，真实购物
1.同学们先熟悉自己所穿衣物的英文名称，并联想自己穿的各种衣物，找出相应的英文名词、形容词等。
2.模拟买卖衣服的现场，练习相关对话。

五．Exercise:根据汉语提示完成下列句子。
1．________ you ________ (喜欢)the red hat?
2. Eight，ten，_______，________，sixteen，________…(按规律写出数字)
3. You can come down to Yintai Clothing Store and see _________ (你自己)．
4. We can ________ a good computer _________ (卖给)you．

8. He can buy this T-shirt _________ ________ ________ ________ (以一个好价钱)．

教学探讨与反思
本单元主要是学习“询问和谈论价格”等目标语言，而这个知识与实际生活联系密切。我们每个人都买过东西，在买东西的过程中一定要进行比较与选择，比较与选择的过程就是询问与讨论价格、颜色、大小与款式的过程，就会运用到本单元所学习的知识。所以，要想让学生真正掌握本单元的目标语言，就要给学生提供这些实际的交际活动，通过这些活动运用所学的知识
