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.
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 SI) 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?

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?
