First, the teaching objectives 1. Through the observation, operation, cooperation and exchange activities, preliminary understanding and identification of rectangular, square and round, 2. In the process of hands-on operation to create a sense of space and sense of innovation. Through the extensive use of graphics in life, we can feel that mathematics knowledge is closely related to life and stimulate students’ interest in mathematics learning. Second, the teaching focus: will recognize the rectangular, square and round three, teaching difficulties: experience “face ” in “body ” on the fourth, teaching preparation: multimedia courseware, building blocks, white paper, process
