三、教学过程
Ⅰ. Warming-up and revision
1. Greet the Ss. Check the homework.
2. First let students repeat the numbers 0-9. Then have a free talk. And then ask different students to imitate a shopping scene in a store, talking about clothing and prices in pairs. Show the following clothes and prices on the screen: this purple sweater ($5), that red bag ($8), that yellow shirt ($6), these blue trousers ($ 7), those black shoes ($9), those white socks ($2).
S1: How much is this purple sweater?

3. Tell Ss that some of the numbers are in the wrong order. Check the answers.
4. Let Ss find out the rules of the numbers.
① 13~19 规律：个位数字后加 teen；注意：thirteen, fifteen, eighteen的差别。

③ 20、30等表示几十的数，大部分构成形式为：个位数后加ty，注意twenty, thirty, fifty等。
Ⅲ. Game
1. T: Now let’s play a number game. Count the numbers from one to thirty-one. But when you count to the multiples of “7” or the numbers which contains “7”, you should hot count, instead, say “next”.
e.g. one, two, three, four, five, six, “next”, eight, nine, ten ... thirteen, “next”, fifteen, sixteen, “next” ...
2. Ss work in groups of ten to twelve people and play the game.

Play the recording for the first time, Ss only listen. Then play the recording again. This time Ss listen and circle the numbers they hear.
2. Let Ss look at the picture in 1d. Kate and her mother are talking about some clothes. Ask one student to name the various items of clothing shown. Ask another to point at the price tags and read them aloud.

2. Ss work in pairs. Ask and answer about the things in the picture above.

Ⅸ. Role-play
1. Imagine you work at Mr. Cool's Clothes Store. Read the conversation first and complete the conversation.
2. 指导：首先，快速阅读对话一遍，明确自己售货员的身份，可知第一句话应为“Can I help you?”。
然后，读对话，通过对话中谈到的衣物的颜色或价格等信息来确定是何衣物；或通过所谈到的衣物来填写其颜色或价格。如在女孩购物的情境中，根据所谈到these red and purple one，再与。短文中的“We have skirt in red and purple”信息相对应，可知女孩是想买短裙，价格是$20。男孩谈到需要一双棕色的某物上学穿，再由下文知其仅是28美元，回顾短文可知所谈应是鞋子。男孩还谈到了要买短裤，对应短文内容可知短裤的价格是16美元。
