Teaching content: PEP “compulsory education textbooks, mathematics,” the fourth grade, the next page p. Teaching Objectives: 1. To enable students to find, understand and understand the law of multiplication distribution in mathematical activities such as calculation, observation, communication and induction. 2. In the process of exploring laws to develop students ability to compare, analyze, abstraction and generalization, enhance the use of symbols to express the law of mathematical consciousness, penetrating the combination of numbers and ideas. 3. To further understand the connection between mathematics and life, to find the law of pleasure and sense of success, enhance
