Teaching content: compulsory education curriculum standard experimental textbook Sujiao version of the fourth grade volumes 50 ~ 51 pages. Teaching objectives: ① Students experience the process of matching two things, initially found that the law with a simple match, and can use the found rules to solve simple practical problems. Students in the observation, operation, abstraction, generalization, cooperation and exchange activities, the development of thinking skills, cultivate a sense of the initial symbol. ③ students in the activities to enhance the interest in exploring the laws of mathematics, mathematics learning to develop the emotion. Teaching Points, Difficulties: Through observation, cooperation and exploration, to explore how the collocation of two items can be orderly, to find some of these phenomena simple mathematical rules
