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?

S2: It's five dollars.

S1: How much are these blue trousers?

S2: They're seven dollars.

Ss ask and answer about all the clothes in pairs.

Ⅱ. Listening

1. T: We have learned the numbers 0-9. Today we’ll learn the numbers 10-31 in la, Section B. Listen to the recording and repeat the numbers.

(Play the tapes for the Ss to listen and repeat them. Ask students to listen to the recording and learn the numbers.)

2. Then point to some numbers and ask students to say them out. Ask students to finish writing the numbers individually.

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。

 ② 21～29及31~39等数字的规律：twenty或thirty后加连字符，再加个位数

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.

Ⅳ. Listening

 1. T: Next you will hear a mother and a daughter talking about buying clothes. First listen and circle the numbers you hear in 1a.

 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.

 1. 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. [来源:学科网]

Ⅴ. Pair work

1. T: Now look at the pictures in 1d. Point to the white T- shirt and ask and answer like this:

—How much is the white T- shirt?   —It’s eleven dollars. 

Have students repeat again. Remind them to use is / it’s with T-shirt, skirt, etc, the singular nouns and are / they’re with socks, trousers, the plural nouns. [来源:学_科_网Z_X_X_K]

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

Ⅷ. Reading

1. Mr. Cool's Clothes Store has a great sale. They sell their clothes at a very good price. What are the prices of their clothes? Look at their ads below and fill in the price tags.

(指导：此题是考试中的任务型阅读理解题。捕捉图片中所示物品及短文中对应的价格是解题的关键。学生读短文过程中，划出广告中所售的衣物，然后圈出该物品的价格。最后将衣物名称与价格一一对应，填入价签中。)

2. Ss read the ad and fill in the price tags then check the answers. [来源:学科网]

3. If Ss have something they don't understand. Put up their hands and ask the teacher to explain them. Explain some main sentences that Ss don't understand. 

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。

3. Ss read the conversation and the Mr. Cool's ad and fill in the blanks. Check the answers.

4. Work in a group of three students. Role-play the conversation. 

5. Let some pairs come to the front and role-play the conversation.

X. Homework

1. 按规律复习所学的有关数字的词汇，并强化记忆。

2. 课下复习2b中的短文，并试着复述短文。
