运算律是高度概括的运算知识,是在运算实践中不断总结、归纳,从而抽象概括出来的。乘法分配律作为运算律中抽象程度较高、使用频率较高的一种,支撑着很多数学模型。在引导学生探索乘法分配律的过程中,教师要给予学生充分的空间,让他们对乘法分配律有足够的认识,有深刻的领悟和必要的体验。一、经历探索过程,形成清晰的概念激发学生的主观能动性,让他们自己去经历观察、思考、实验等过程,从而领悟运算律的内涵,能用自己的语言或者
Operation law is a highly general knowledge of computing, is summarized in the computing practice, summarized, and thus abstract out. Multiplication assignment law, as a high degree of abstraction and high frequency of use in arithmetic laws, supports many mathematical models. In guiding students to explore the law of multiplication distribution, teachers should give students enough space to allow them to have sufficient understanding of the law of multiplication and distribution, with profound insight and necessary experience. First, the process of exploration, the formation of a clear concept to stimulate students’ subjective initiative, let them go through the process of observation, thinking, experiment, and so on to comprehend the connotation of arithmetic law, in their own language or
