Step 2.Leading-in（略）

Step 3.Presentaion（略）

Step 4.Practice

1.Check and learn: How do you like it? It’s/ They’re very pretty.

Underline the sentences for your answers.

How do you like this skirt?It’s very pretty.

教師帶讀，并板書。用圖片dress,hat,socks 替換skirt 練習(xí)。

2.Check and learn: How much is it? It’s $89.

（1）Underline the sentences：How much is it? It’s $89.

PPT: $-dollar,￥-yuan It’s RMB.教師帶讀dollar（圖片呈現(xiàn)美元和人民幣，以示區(qū)別）。

（2）教師板書句型并帶讀：How much is it/...? It’s $89.

（3）T: How much is it? S:It’s 50 yuan.

T: How much is it? S: It’s 80 yuan.（PPT 呈現(xiàn)地?cái)偡b）Do you want to know how much it is? How to ask the vendor?（教師指著另外兩種物品問）

Ss: How much is it?

T: It’s 100 yuan.

設(shè)計(jì)意圖：從表層信息到深層信息，教師通過提出有層次性的問題，從是什么到為什么再到怎么做，環(huán)環(huán)相扣，引領(lǐng)學(xué)生走向深度思維。在層層遞進(jìn)的引導(dǎo)性問題情境中，學(xué)生思維的靈活性、邏輯性、批判性和創(chuàng)造性也得到有效培養(yǎng)。

3.Pairwork.

T: Can you ask and answer in pairs?（PPT 呈現(xiàn)地?cái)偟乃臉迂浳铮?/p>

...

S1: How much is it?

S2: It’s 35 yuan.

設(shè)計(jì)意圖：在問題情境中，深入思考文本內(nèi)容，學(xué)習(xí)和運(yùn)用目標(biāo)語言，較好地培養(yǎng)了學(xué)生思維的深刻性和靈活性，能舉一反三。

4.Let’s think.

Why can’t Sarah buy this skirt?

（1）在文中找出答案并畫線：Because it’s too expensive/cheap.

（2）T: The skirt is $89.Do you know the Exchange rate of RMB and US dollar? 你們知道人民幣和美元的匯率嗎？Let’s go to Baidu and find out.（通過百度網(wǎng)頁查詢?nèi)嗣駧艆R率）

1 美元≈6.6995 人民幣 89美元=596.2288 人民幣

設(shè)計(jì)意圖：學(xué)習(xí)利用百度搜索的策略，通過貨幣兌換，感受expensive 的含義。

（3）So The skirt is $89.It’s 630 yuan.It’s very expensive.

詞卡教學(xué)：expensive,Read one by one.

T: Look at the jacket.It’s$100.

Ss: It’s expensive.

T: So what is expensive in this street stall in your opinion？

（PPT 呈現(xiàn)umbrella,toy car,football，有些貴，有些便宜）

S1: I think the umbrella is expensive.

S2: ...

設(shè)計(jì)意圖：在相互了解的過程中批判性思維得到鍛煉。

（4）T: Are the pants expensive?（PPT 呈現(xiàn)pants 售價(jià)30 元，售價(jià)便宜）

T&S: No.They are cheap.

Learn: cheap， ea,ee,eat,see,sea,meat,keep,three,bea,cheap

T: What do you think is cheap in this street stall?

S1/2/3: I think...is cheap.

設(shè)計(jì)意圖：在創(chuàng)設(shè)的地?cái)偳榫持袑W(xué)習(xí)新詞，學(xué)生能較好地領(lǐng)會(huì)其含義，進(jìn)一步學(xué)習(xí)單向發(fā)音規(guī)則。

（5）T: So will you buy this umbrella? ...Why? ...Yes.It’s too expensive.（板書）

設(shè)計(jì)意圖：創(chuàng)設(shè)批判性問題情境“Will you buy...?”，學(xué)生運(yùn)用生活經(jīng)驗(yàn)來分析判定該不該買，該買什么。在理解了expensive 和cheap 的基礎(chǔ)上，學(xué)生通過分析判斷，思維的深刻性、靈活性、批判性和創(chuàng)造性都得到鍛煉和提升。

5.Talk about your experience and give suggestions to Sarah.

T: And Sarah will not buy this skirt because mum says“Sorry,Sarah.It’s too expensive.”But Sarah likes it.How does she feel?

Sn: She feels sad./...

T: Yes,she is not happy.

T: Have you got the same experience as Sarah? How did you feel?

Sn: No./ Yes,sad,bored,upset...

T: What do you want to say to Sarah?

Ss: It doesn’t matter./You can choose another one./...I’m sorry.

Emotion: We should buy suitable things at a reasonable price.We buy things not because they’re cheap or they’re expensive，but because we need them and their price is reasonable.

設(shè)計(jì)意圖：結(jié)合文本圖片的情境和所學(xué)內(nèi)容，引導(dǎo)學(xué)生體會(huì)文本主人公的思維。同時(shí)，學(xué)生通過思考，學(xué)會(huì)關(guān)心他人，并能提供適當(dāng)?shù)慕ㄗh來開導(dǎo)、幫助他人，引導(dǎo)學(xué)生學(xué)會(huì)友善地“Care for others”。

6.Listen and imitate.

7.Practise the dialouge.

T: Now you know the text very well.Can you finish the dialogue in this way?

設(shè)計(jì)意圖：創(chuàng)設(shè)學(xué)習(xí)目標(biāo)語言規(guī)則的文本情境，引導(dǎo)學(xué)生深入理解和運(yùn)用句型規(guī)則、差異和語用情境。

Step 5.Consolidation

1.Watch a new video,find out the answers and think.

T: Boys and girls,Sarah and her mum go to another shop.Let’s watch the video and find out if Sarah will buy something.How much is it?

T&S: What will Sarah buy?A dress.How much is it? It’s eighty-five yuan.Is it expensive?No...It’s cheap.Yes,it’s cheap.Is it pretty?...Yes.So Sarah takes the suitable dress at a reasonable price.Right? What do you think of Sarah?...She is happy / great!

設(shè)計(jì)意圖：利用文本信息創(chuàng)造性地創(chuàng)設(shè)從不能買到能買的情境，引導(dǎo)學(xué)生再次學(xué)習(xí)和建構(gòu)目標(biāo)語言，為任務(wù)的完成打下基礎(chǔ)，提升思維的深刻性、創(chuàng)造性和敏捷性。

2.Fulfill the task: Set up street stalls and buy something.

OK,boys and girls.Now let’s set out things on the street.We have our own street stalls.I need some vendors to sell things.And the others are customers.You can buy things with your coupons.Who wants to be the vendors? As rewards,you can get another coupon of 10 yuan...Thank you.

T: Boys and girls,today we’ve learned how to ask and describe something,and how to ask and answer the price.I’d like you to buy things you need with reasonable price.You can go to street stall and find what you need.OK?

設(shè)計(jì)意圖：學(xué)生在交際情境中發(fā)現(xiàn)、感知、理解、體驗(yàn)語言，并吸收、內(nèi)化和建構(gòu)成自己的語言機(jī)制，充分發(fā)揮想象力，從而能夠獨(dú)立地、創(chuàng)造性地解決實(shí)際問題。設(shè)置情境去解決問題，完成任務(wù)也是發(fā)展創(chuàng)造性思維的重要途徑。

Step 6.Homework（略）
