教学方法（或模式）

情境探疑教学模式

教学过程：

第一课时

一、带入情境

确立目标

1．Greeting：

T：Hello! Boys and girls! (注意使用复数名词).

How are you? How old are you? 2．Review:复数名词和数字。

出示幻灯片2、3、4，复习数字1-100。

①

猜测游戏：桌子上放着一个铅笔盒，里面有一支铅笔。

T: What is this?

S: It is a pencil-case.

(教师将铅笔盒藏起来再问学生)

T:I can’t find my pencil-case. Where is it?

Ss：On the desk.

T: Thank you .Where is my pencil?

Ss：It is 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:_____________.

T：I want more and more books, do you want to count with me ?

OK, let’s play a game ‘Clap’. (注意学生的发音，纠正十几和几十的读法)。

二、凭借情境

解疑探究

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put……on，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put……on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。[

三、拓展情境

达标训练

．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）

What’s 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：What’s this?

S2:A boy.

T:How many boys?

Ss: Twenty boys.

T:Ask and answer in your group.

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)。

四、聚焦情境

反思构建

1．T: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.

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、巩固练习：

出示幻灯片5、6。

六、结束课堂

出示幻灯片7

七、板书设计：
