“练”在《新华字典》里的解释为:反复学习,多次操作。而“恋”的解释则为:想念不忘,爱慕不舍,不忍舍弃,不想分开。这两个看似毫不相关的词语如何在数学计算教学中有机地统一或是转换呢?今天我就借此谈谈自己的想法。我国小学数学历来都非常重视计算教学,在《义务教育数学课 “Practice ” in “Xinhua Dictionary” in the explanation: repeated learning, multiple operations. The “Love ” explanation is: do not forget, love sad, could not bear to give up, do not want to separate. How can these seemingly unrelated words be organically unified or transformed in mathematics teaching? I will take this opportunity to talk about my own thoughts today. Our primary school mathematics has always attached great importance to the calculation of teaching, in "compulsory education math class
