Teaching Procedures	Tips
Step 1 Lead in
Review Step1: Show Ss teaching goals. T: Morning everyone. Today we are going to count the numbers over 10 and find out the rules. Step2: Ask Ss to do Q&A on P5-P7. (T asks Ss to guess the price of the things given on PPT, and Ss only have three chances. When they answer the questions, the sentence patterns must be used: It’s…dollars. Do they …? Does he/ she…? Yes …do/ does. No …do/ does. ) Lead in Step1: The T can present the target numbers on P8-P11 and teach Ss how to read them in English. Step2: T asks Ss to observe and find the rules. ( Ss can count numbers line by line, from 1 to 50. T can ask Ss to read the words on PPT P8-P11. Then ask Ss to find out the rules. Then T asks Ss to write the numbers down according to the rules in their exercise books: 1-12 13-19 20-23 30,40,50,60,70,80,90 to make sure Ss can write correctly.) Step3: T asks  Ss to make a summary about numbers. 英语数词不难记，找出规律就容易。 零至十二词不同，一个一个单独记， 后面加teen变十几，thirteen , fifteen辨仔细， eighteen 只有一个t，两个音节念清晰。 二十至九十后加ty，twenty不同重点记， forty去掉字母u，thirty, fifty更出奇， 十位数后个位数，表示数值几十几， 按序排列不费力，连字符号莫丢弃。
Step 2Presentation
1a Step1: T asks Ss to listen and repeat. The T can also have them chant these numbers. Step2: T asks Ss to have a Group competition. (Ss count and spell numbers from 10 to 31 in groups. The group who can finish first can get a star.) 1b The activity is to give Ss practice in guessing word meaning. Teaching Tip: Board Writing Relay Have Ss compete to write the words for the numbers 1-31 on the board. Divide Ss into small groups of four to six. Invite two groups to the front of the class and have them compete against each other. The group that first finishes writing the numbers 1 to 31 on the board is the winner. However,each group has only one pen/stick of chalk. Ss must take turns to write each of the numbers before passing the pen/stick of chalk to another member of their group. The winning group gets to pick which two groups will compete next. If both groups finish at the same time, the T will declare the group with the neatest handwriting the winner. Answers:row 2 should be row 4 row 4 should be row 2 1c The activity is to provide guided listening practice with the target language. Teaching Tip:Recalling Tips Encourage Ss to recall useful tips they may have been taught in the past.For 1c, ask Ss if they can remember which words they are likely to hear before they hear a price.Elicit the answer:How much? Answers:fifteen(15),eleven(11),twenty (20),sixteen(16) (After listening, T can ask Ss to answer the following questions according to the picture in 1d to practice the target structure. How much are the black shoes? How much is the blue sweater? How much are these trousers? How much is the T-shirt? How much is the green sweater? ) 1d The activity is toprovide listening practice with the target language. Teaching Tip:Shopping for Fun In the US,clothes shopping is often considered a fun activity.Many young people will tell you that they like to go to the mall in their free time.What they often mean is that they like to browse in stores,perhaps trying on interesting outfits. These young people don't always buy something when they go to a store.They might not have any money. If you go shopping without planning to buy something,you can say you are "just browsing" or "window-shopping". Answers:Circled:blue sweater,socks,T-shirt,trousers,green sweater Checked:trousers 1e The activity is toprovide speaking practice with the target language. Teaching Tip:Take a Test For 1e,have Ss test each other. Have Ss close their textbooks and take out a piece of paper. Ask for the price of each item in the picture in 1d.Tell Ss that they can write down the prices but not the questions. Have Ss compare answers. Then have Ss open their textbooks and repeat the questions.
Step 3Language points
Language points: 基数词的用法 数词是表示数量或顺序的词， 可分为基数词和序数词两种。 表示数目多少的词叫基数词， 如one, two, three等。 基数词可指代或修饰可数名词。 1) 表示数量，置于名词前。 2) 表示编号，置于名词后。名词和基数词首字母通常大写。 3) 表示号码。 4) 表示年龄。 5) 表示时间。 6) 表示计算。
Step 4 Exercises & Homework
Exercises Step1: Ask Ss to do the exercises on PPT P27-P29. Step2: Ask Ss to make a summary about language points they learned today. Homework 1. Preview the passage in Section B 2b. 2. Do the exercises in students’ book.
Teaching Reflection	I designed many activities to help students to master the numbers from one to one hundred and they can say them well but some of the students don't know how to write the numbers from one to thirty-nine, so students must write down the words at the end of the class to make sure they can spell well.
