因数对于小学五年级学生而言,虽然是新概念,但其在整数除法及倍数的概念学习中早已经有所渗透,其概念的理解深深影响以后的学习。结合教科书内容,将其转化为适合学生的学习活动,并利用电子白板的互动特性,让学生在游戏中学习,熟练找出整数的所有因数,进而分析归纳解题策略,为学生未来解决问题打下坚实的基础。抢数活动的基本规则是:教师给定数的范围(如1~12),学生抢走 Although the factor is a new concept for the fifth grader in primary school, it has long been infiltrated in the concept of integer division and multiples, and the understanding of the concept deeply influences the subsequent study. Combined with textbooks, will be transformed into learning activities suitable for students, and the interactive features of the whiteboard so that students learn in the game, skilled to find out all the factors of the integer, and then analyze and solve the problem solving strategies for students to solve the problem laid in the future solid foundation. The basic rules for grabbing a few activities are: the range of teachers’ given numbers (eg 1 ~ 12), the students take away
