【教学目标】1.从具体实例中理解因数和倍数的意义,掌握“求一个数的因数”的方法。2.经历“求一个数的因数”的过程,归纳出“求一个数的因数”的特点,体现从具体到抽象的推理过程。3.培养学生抽象、概括的能力,渗透事物之间相互联系、相互依存的辩证唯物主义观点。【教学流程】活动一:自学课本师:什么是因数?什么是倍数?自学课本,仔细看图,认真读书,边读边想。(全班展示交流“12的因数和倍数”)
【Teaching Objectives】 1. Understand the meaning of factors and multiples from the specific examples, master “a factor of seeking a number” method. 2. Experiencing the process of “seeking the factor of a number”, the characteristic of “factor of seeking a number” is summed up, reflecting the process of reasoning from concrete to abstract. 3. Cultivate students’ abstract and general abilities, infiltrate the dialectical materialistic views of interrelation and interdependence between things. Teaching Process Activity 1: Self-taught textbook: What is the factor? What is multiples? Self-study textbooks, carefully read the picture, study hard, read and think. (Class show exchange “factor of 12 and multiple ”)
