4. 出示Ask and answer的图片，让学生开展对子活动，让更多的学生能够操练How many …are there? There are…，复习和巩固词汇和句型。还可以把挂图贴在黑板上，让学生根据挂图中的形状拼画进行问答。
S1: Look at Picture 3. How many circles are there?
S2: There are four circles.
Post-task activities
1. 让学生用不同的形状画一幢房子，然后根据教师的示范，用一段话进行介绍。让学生综合巩固所学的知识，提高语言表达能力。

2. 把挂图贴在黑板上，让学生看图中各种形状拼画，然后把不同大小、颜色的各种形状分发给学生，让他们自由分组，发挥创意，拼出一幅图画。
S1: I have a circle. I have a star too.
S2:1 have two triangles and a rectangle.
S3: I have ...
S1: Let’s make a ...
然后请个别小组上来介绍他们的作品，教师根据作品提问，让其他学生回答。
