【教学过程】

Ⅰ. Pre-task preparations

1．播放一首与形状有关的歌曲（见“参考资料”），让学生跟着录音一起唱，为接下来的学习渲染气氛。拿出一张正方形的纸，接着将纸对折，呈现一个三角形，然后再换一种方式对折，呈现一个长方形。通过演示，引出单元话题“形状”。

T: (point at the paper) Look at the paper. It's a square.

(Fold the paper and point at the shape) Look, is it a square now?

T: It's a triangle, (fold the paper in another way and point at the shape) Is it a triangle?

S1: No, it isn't.

Ⅱ. While-task procedures

1．出示Look and learn栏目中的单词图片，学生在理解意思的基础上仔细听其发音后进行模仿，并进行拼读。模仿和拼读活动可以是集体的，也可以是个别的。

T: (show the flashcard for square) Look, it's a square. Square. S-Q-U-A-R-E, square.

Ss: Square. S-Q-U-A-R-E, square.

2．What's missing? 游戏。将所有单词图片呈现给学生，任意抽走一张，让学生说出被抽走的单词。前几次可以通过图片消失形式，后面几次可以是以单词消失的形式。然后让学生集体拼读这些单词。

T: What's missing?

S1: A circle.

Ss: Circle. C-I-R-C-L-E, circle.

…

3．让学生做Draw and say，在一张白纸上画一画生活中常见的与这些形状匹配的东西，每个形状画一样。接着请一个学生上来，教师进行示范介绍。然后，让学生与同桌交流自己的画。通过画画和介绍，建立起形状与生活的联系，进一步巩固所学单词。

Ss: (draw an object in the shape of circle.)

T: (show S1's picture) Look, this is an orange. It's a circle. This is a book. It's a rectangle.

S1: (show the picture to S2) This is a ... It's a...

S2: (show the picture to S1) This is a ... It's a...

4．在上一活动的基础上，用歌曲Shape song（见“参考资料”）中的句型介绍学生所画的东西，帮助学生理解歌词，然后播放歌曲，让学生歌唱，通过歌曲拓展形状的语言表达方式。

T: (point at the picture of a ball) Look, this is a circle. It's a ball. A circle's like a ball.

Ss: A circle's like a ball.

T: (point at the picture of a box) What is like a box?

S1: A square is like a box.

T: (trace the shape) How many sides does a square have? Let's count.

Ss: One, two, three, four.

T: Yes, a square has four sides. How about a triangle? How many sides does a triangle have?

Ss: Three.

Ⅲ. Post-task activities

1．让学生指着教室里的某些不同形状的东西进行介绍，培养学生的观察能力和语言表达能力。

S1: This is our classroom.

It's big and clean.

We can see many shapes in our classroom.

I can see a flag on the wall.

It's a rectangle.

A rectangle is like a flag.

I can see a clock on the wall too.

It's a circle.

A circle's like a clock.

Look, that's a TV.

It's a square.

…

2．I spy游戏。可让学生分组或全班一起玩游戏。展示一些物品，然后将它们放入袋中，每次请一名学生以所看到的物品出题，说：“I spy with my little eyes something (shape).”猜的人可追问问题，出题的学生只能回答“Yes”或“No”。

S1: I spy with my little eyes something circle.

S2: Is it red?

S1: No.

S3: Is it white?

S1: Yes.

S4: Is it big?

S1: Yes.

S2: Is it a clock?
