四.教学过程:
(一)开始上课和复习:
1.问候:
T:Hello! Boys and girls!(注意使用复数名词).
2.复习复数名词和数字。(结合第4课学过的方位词和Where is ?的句型)
①桌子上放着一个铅笔盒,里面有一支铅笔。
T:I can’t find my pencil-case. Where is it?
全班:On the desk.
T: Thank you .Where is my pencil?
全班:It’s in the pencil-case.
T: Oh, I have one pencil.(板书)(找一名同学)Where is your pencil?
:On the desk.
T: Give me, please. Now I have two pencils(板书)
You say it, please.
下面依次用其他同学的其它用品进行练习并板书 books, erasers, markers…… 在练习过程中,设一些小圈套,把数字和复数名词错误的进行组合,如one markers,there book等等,同学们要通过重复正确答案表示同意或纠正错误。(这样既可以集中同学的注意力,又可以练习听力,还有利于和时纠正同学错误)
②练习之后,教师说:I want more and more markers, do you want to count with me ?
做游戏Clap 注意同学的发音,尤其是十几和几十的读法。
(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。根据同学人数调整所数的'数字,争取让每个同学都数到,可以在数到个别数字时做出不同的变化。)
③T:What else do you have? Please find out the cards under your chairs.
教师出示数字卡片,拿着相同数字卡片的同学读出数字再加上后面的图案读出来。如教师出示fifty-four时,拿者54卡片的同学站起来,读fifty-four cats.
(二)教授重要概念How many ? .
1.引入句型How many ? .
练习几组之后,问一个同学: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示)
How many monkeys?(用手指着19) =www.XXJXSJ六十铺中小学教育=小学优秀教案网
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? There erasers(板书划线局部)(举起两本书)How many books do I have?
全班:Two books.
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同学,拿起他的卡片)
What’s this?
全班:A chair.
T翻过来,看elephants数字) How many elephants?
:Twenty elephants.
T:(问全班) Can you ask?(换另一个同学的卡片)
全班:What’s this?
:A boy.
全班:How many boys?
:Sixty 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,有些同学可能出现将不可数名词放在How many 之后的现象,要给予提示,请同学总结:
How many 句型用来提问数量,How many后面的名词要加s(也就是用复数名词)。
3.巩固

同学自读课文第一局部,然后男女分角色亮度第一、二幅画。
T:First,How many books does Danny have?
