乘法分配律是简便运算中的难点问题,展现的是学生的思维历程,学生很难理解其意义。本文用笔者自身实践,谈乘法分配律的教学与思考。通过建立、应用、辨析,即开启思维、实践思维、挑战思维,促进乘法运算定律知识在学生的大脑中真正建构,使学生的学习效果事半功倍。同时在教学当中渗透归类思想,使学生学会数学地思考问题,从而达成提升学生数学素养的目的。
Multiplication distribution law is a simple operation of the difficult problem, showing the students thinking process, the students is difficult to understand its significance. This article uses the author’s own practice to talk about the teaching and thinking of the law of multiplication distribution. Through the establishment, application, discrimination, that is, to open thinking, practice thinking, challenge thinking, and promote the law of multiplication law knowledge in the brain of students truly construct, make the students learn more efficiently. At the same time, it infiltrates the idea of classifying in teaching so as to enable students to think mathematically to solve the problem so as to achieve the purpose of improving students’ mathematical accomplishment.
