  • Review
Step1: T asks Ss to see the pictures and say the price on PPT P5-P6.
(T shows pictures one by one and ask students the question: How much is an egg? How much are the socks? How much is the pencil box? How much is the pen? How much is the hat? Ss should answer the question with the sentence patterns like: They are … It is … If Ss cannot say the words correctly, T must correct them .)
Step2: T asks Ss to do Q&A in pairs.  
(Ss ask and answer questions with the sentence patterns:
A:How much is/are...?
B:It's/They're _______ dollars.)
Step3: T asks Ss to say the numbers as fast as they can so that they can have a good review of the numbers they have learned.  
(If Ss see the number, just stand up to say it out.)
Step 2While-reading
  • 2a
The activity is to provide practice with the target language as a warm-up for the reading.
Teaching Tip:What's the price?
Have Ss work in pairs to match the clothes and prices in 2a.Then conduct a survey about how much they think each item costs in their town.It may be easier to do this in Chinese yuan rather than dollars.The T can then introduce the exchange rate between the US dollar and the Chinese yuan,so that Ss can compare the prices they matched in 2a and the prices of the clothes in their town.
  • 2b
The activity is to provide reading practice with the target language.
Step 1: T askS Ss tolook at the title and the picture and answer the following
questions.
Q1: What can you see in the picture?
Q2: Where are the clothes?
Q3: What’s the store’s name?
Q4: Predict the prices of these clothes.
Step 2: Have Ss work in pairs.Have one S cover the picture and look only at the textbook passage while the other S covers the textbook passage and looks only at the picture.While one S reads the passage,the other S tries to fill in the price tags.Then have Ss change roles.
Answers : green sweaters:$15yellow sweaters:$12
black trousers (for boys):$22 shorts (for boys):$16
purple skirts (for girls):$20 jackets:$30
black shoes:$28socks:$2 for three pairs
Step 3: Have Ss read the ad again and answer the questions.
Q1. Can we buy blue sweaters in Mr. Cool's Clothes Store?
Q2. Which is cheaper, purple skirts or black shoes?   
Q3. How much are six pairs of socks?
(T tells Ss what scan is: to read carefully and find the details. Ss read para by para, and do the tasks. After Ss read the passage together, T should correct their pronunciation, and lead them to read the words the sentences where they have problems again to make sure they can read correctly. T asks Ss to answer the questions after each paragraph. They can share the answers one by one or in a row or in a line. It's better for T to correct their pronunciation of the words or grammar mistakes when Ss answer questions.)
  • 2c
The activity is to provide readingand writing practice with the target language.
Teaching Tip: Helpful Words
For weaker Ss who may have difficulties with this activity,provide them with the set of words to choose from.You can write the words on a piece of paper and give it only to those Ss who need extra help. In doing so,you still allow stronger Ss to try the activity on their own.
For 2c,the words are:
much,take,skirt,shorts,dollars,skirts,can,shoes,twenty,only,sixteen,shoes
Answers: can,skirt,skirts,much,twenty/20,take,shoes,only,dollars, sixteen/16,shoes,shorts  
Then the T can ask Ss to chant the conversation to check their pronunciation and intonation. Then invite some open pairs to role-play in class.
Step 3Language Points
1. Mr. Cool’s Clothes Store 酷先生服装店(教材P41 2b)
在英语中, 服装店等专有名词(人名、地名、店名等)的每个单词的首字母均要大写。 例如:No. 6 Middle School 第六中学; Huaxing Clothes Store 华兴服装店
2. Come and buy your clothes at our great sale!  (教材P41 2b)
句式剖析: 本句是一个祈使句,表示建议。其中and连接两个动词come和buy,表示动作的一先一后。祈使句通常省略主语you,以动词原形开头。buy是及物动词, 反义词是sell(卖),常见用法有:buy sb. sth. = buy sth. for sb. 给某人买某物  buy sth. from... 从……买某物
1) sale是动词sell的名词形式。
2) on sale 折价销售; 减价出售;for sale 待售
3) at a/one's great sale相当于on sale,其中at表示“以……(价格)”。
3.We sell all our clothes at very good prices.  (教材P41 2b)
price作名词, 常用于以下结构:
1) at... prices/at a... price  以……的价格
2) the price of...  ……的价格表示价格高低用high(高的) 和 low(低的);
表示物品贵或便宜用expensive(昂贵的)和 cheap(便宜的)。
4. For girls, we have skirts in purple for only $20! (教材P41 2b)
1) for girls中的for做介词, 在此处表示对象,意为“对……来说”。
2) 句中的介词in在此处用于表示物品的颜色。
3) for only $20 中的介词for用在此处表示价格, 意为“以……金额”。
Step 4 Exercises& Homework
Exercises
Step1: Ask Ss to do the exercises on PPT P28-P30.
Step2: Ask Ss to make a summary about what they learned today.
Homework
1. Read and recite the new words and phrases.
2. Do the exercises in students’ book.
Teaching Reflection
I didn't make full use of the sentences in this passage because students only make conversations using some simple sentences and what we learned before. Some sentences aren't practiced in the conversation part like:We have skirt in purple for only twenty yuan. We sell all our clothes at very good prices. And students didn't master the key sentences well so the class is not so effective.
