Boys and girls! (注意使用复数名词). How are you? How old are you?2Reivew:复数名词和数字。延续上节课的猜测游戏：桌子上放着一个铅笔盒，里面有一支铅笔。T: Whats this? S: Its a pencil-case.(教师将铅笔盒藏起来再问学生)T:I cant find my pencil-case. Where is it?Ss：On the desk.T: Thank you .Where is my pencil?Ss：Its in the pencil-case.T: Oh, I have one pencil.(板书)（找一名学生）Where is your pencil?S: On the desk.T: Give me, please. Now I have two pencils(板书)You say it, please.Ss:_.（下面依次用类似方法及其他学生的其它用品进行练习并板书 books, erasers, markers 在练习过程中，可以向学生多要些东西。设一些小圈套，把数字和复数名词错误的进行组合，如one markers,three book等等，学生们要通过重复正确答案表示同意或纠正错误。这样既可以集中学生的注意力，又可以练习听力，还有利于及时纠正学生错误）T：I want more and more books, do you want to count with me ?OK, lets play a game Clap. (注意学生的发音，纠正十几和几十的读法)。Game: Please count from one to one hundred.（在1-20的时候，用1-to-1,1-to-2的节奏，20-29用twen ty -one的节奏，然后数整十到一百，用one-to-twenty 的节奏。根据学生人数调整所数的数字，争取让每个学生都数到，可以在数到个别数字时做出不同的变化。）PracticeT: OK,Lets play a game. Find friend.T: What else do you have? Please find out the cards under your chairs.（教师拿出自己手中的数字卡片，让持有相同数字的同学站起来读出卡片上的数字,并读出卡片正面上的单词，组成一个数字短语）S: I have 35 apples.(这个游戏也可以变换一下形式，让同学与同学之间来做这个游戏，这样能够让更多的同学融入到学习中来。)(二) New concept :How many ? .1引入句型How many ? .练习几组之后，问一个学生：What do you have?S:I have 19 monkeys.T: Can you say it, again?(尽量用表情和体态来表现)How many monkeys?(用手指着19)S:19 monkeys.T:(举起三块橡皮)Look! How many erasers do I have? How many? (开始数) One, two, there. How many eraser? Three erasers.（举起两本书）How many books do I have?Ss：Two books.T: Let me put five books on the two books. How many books do I have?(如果学生不能正确理解puton，教师可以边说边做动作) Ss: Seven books.T: Let me put twelve books on the seven books. How many books do I have?Ss: Nineteen books.请单个同学解释puton的含义。如果学生还是不能理解的话，教师可以适当多做几次示范。（在这个环节中教师可以给学生们多做几组不同的示范，例如：putin，putout等等。）2练习句型How many ,总结句型特点。T：（找一名刚才在游戏中没有被提问过的学生，拿起他的卡片）Whats this?Ss：A chair.T:(翻过来，看chair数字) How many chairs in our classroom?Ss: Twenty-two chairs.T:(问全班) Can you ask?(换另一个同学的卡片)S1：Whats this?S2:A boy.T:How many boys?Ss: Twenty boys.T:Ask and answer in your group.在小组内练习，可以用卡片，也可以用实物。小组练习以后，有些学生可能出现将不可数名词放在How many 之后的现象，要给予提示，请学生总结：How many 句型用来提问数量，How many后面的名词要加s(也就是用名词复数)。3巩固1T:How many books does Danny have: Listen to the tape and answer the questions.T:First,How many books does Danny have?(只放一、二幅图的录音)S;Eight books.放第三、四幅图的录音（提示学生are,there也表示“有”）T:How many books are there on the desk?S:sixteen books.巩固练习there be 句型：将一个写有there be 句型的纸条剪开，每个单词分一段，然后让同学将句子恢复成原状，再组成 一个完整的there be 句型。根据时间，可多做几个这样的练习。齐读最后一部分：T:What happened?S:Danny falls down.师生一起总结表示“有”的词has、 have、there be并进行简单的区分。五板书设计Lesson 5: How many Do I have?1 pencil-2 pencils1 book -5 books1 marker-12 markers1 eraser-4 erasersHow many ereasers?-ereasers.六、练习1、连线：25+13 one hundred 49+37 thirty-eight 80+20 ninety-nine 56+43 eighty-six2、根据规律写数字 One three five _ _ _ Eleven twelve fourteen seventeen _ _ _ Twenty-two Twenty-four Twent
