Teaching Procedures	Tips
Step 1 Warm-up
Show Ss teaching goals. T: Morning everyone. Today we are going to learn the prepositions in / on / at and the ordinal numbers. Show Ss PPT P5-P6. Ask Ss to say the months in English and then try to spell the words. (Ask B-level students to read and spell. If Ss can’t answer correctly, T must correct their grammar mistakes.) Show Ss PPT P7-P8. Let Ss look at the chart on the left, then write down new conversations following the example. Free Talk T can make this activity as a competition. There are seven festivals on PPT P9. For each festival, T can ask Ss to stand up and speak the date out aloud. The S who stands up first and say the date in English correctly will be the winner. (These festivals are known by everyone, so they don’t need to talk with the partners. If Ss can’t answer correctly, T must correct their mistakes.)
Step 2Grammar
Grammar Focus Ask Ss to read the contents on grammar focus part, and make a summary. (T can show the questions on the blackboard like: 1. How do we ask for a person’s birthday? 2.How do we say a date? Ask them to talk about the questions in groups. After that T can ask Ss to make a summary according to the grammar in their books. T can give Ss more examples to help Ss understand the grammar.) Grammar 1. 询问他人生日日期：When is _____ birthday? 2. “名词+’s”所有格 “名词+’s”所有格主要用于有生命的名词的所有关系。 1) 单数名词后加“ ’s ”（以-s结尾的人名后加“ ’ ”或“ ’s ”）。 2) 以-s结尾的复数名词只加“ ’ ”，不以-s结尾的复数名词通常加“ ’s ”。 3) 表示几个人共有，仅在最后一个人的名字后加“’s”；表示各自所有时，应在各个名字后加“’s”。 of 所有格 1) of 所有格多用于表示无生命事物的名词的所有关系。 a map of China 一幅中国地图 2) of 所有格也可用于表示人和其他有生命的名词的所有关系。 the name of her cat 她的猫的名字 3) ’s所有格和of 所有格有时可以互相转换。 the girl’s new dress = the new dress of the girl 这个女孩的新连衣裙 3. 序数词   表示人或事物先后顺序的数词叫序数词。序数词大多数是由基数词变化而来的，序数词往往与定冠词the连用。 序数词的构成   1) 1-3的序数词first / second / third与基数词差别很大，应逐一记忆。 2) 4-19的序数词是在相应基数词后加上后缀-th。注意fifth，eighth，ninth，twelfth的特殊性。 3) 整十的序数词，通常是把相应的整十的基数词词尾的y变成ie，再加-th。 4) 表示“第几十几”，只需把个位数的基数词变为序数词，十位数不变。 5) 序数词的缩写形式是在阿拉伯数字后直接加上序数词的最后两个字母。 巧记妙学：基变序，有规律，多数词尾加-th。一二三，特殊记，词尾字母t, d, d。 八去t，九去e，f 来把 ve替，然后再加-th。遇到整十需注意，变 y为ie，然后再加-th。若是遇到几十几，只变个位数字就可以；中间连字符“-”，千万别忘记。 序数词的用法 1) 序数词前一般要加定冠词the。 2) 序数词常用来修饰名词，但当名词前有形容词性物主代词等限定词时，序数词前不用定冠词。 3) 表示分数时，分子用基数词，写在前面；分母用序数词，写在后面。当分子大于1的时候，表示分母的序数词要+s。 4) 序数词前有时也可加不定冠词a / an，这时表示的不再是具体范围内的“第几”，而是表示在原有基础上的“又一个，另一个”。
Step 3Practice
3a Ask Ss to match the questions and answers. Answers: 1.b  2.d  3.e  4.c  5.a (This part is very easy, T just need to ask Ss to answer one by one in a row or a line.) Ask Ss to practice the conversation in 3a. T: Suppose you are a reporter and you have a chance tointerview your partner, and your partner needs to answer your questions. Practice the conversations in 3a. (Ss can practice first and make their own conversations later. Then they can share in class. ) 3b Ask Ss to complete the conversation and practice it with their partners. (When Ss share their answers, T should ask them to explain the reasons. Ss read the conversations and T explains the language points. After students shared their answers, T asks Ss to make a conversation in class.) Answers: 1. old  2. I’m  3. when  4. birthday  5. on  6. in 3c Ask Ss to find out their group members’ birthdays and ages and line up from the youngest to the oldest. Ask Ss to finish the task in 3c and fill in the chart. (Ss are suggested to use the sentence patterns: A: How old are you, Li Hai? B: I'm thirteen years old. A: When is your birthday? B: It's on February 20th. Give Ss two minutes to ask and make a summary first. Then ask Ss to share like this: In my group, … is the oldest. … is the second oldest. … is the youngest.)
Step 4 Exercises & Homework
Exercises Ask Ss to do the exercises on PPT P27-P30. T ask Ss to make a summary about language points they learned today. Homework Preview the new words and phrases in Section B (1a-1d). Do the exercises in students’ book.
Teaching Reflection	Ss have enough training for the sentence patterns: When is … birthday? It’s on… However, most Ss are still not so clear about the expressions of dates. More exercises should be done to help them master the expressions of dates.
