摘  要：运算定律是小学阶段十分重要的教学内容，掌握正确的运算方法、运算规律对小学生而言非常重要。对于初接触数学运算的小学生而言，运算定律也许比较难以理解，想要让小学生深刻记忆、掌握运算定律，需要教师采取特殊手段，比如情境教学法、小组合作教学法等。同时，小学数学课堂上应当重视对学生口算能力的培养，更加有耐心，细心，帮助学生更有效地应用数学运算定律，提高学生解决数学问题的能力。本文就探究优化小学数学运算定律教学的新方法进行了以下阐述。

A New Method of Optimizing Teaching of Mathematical Operation Law in Primary School

ZHANG Junxia （Jingmei Primary School，Pingchuan District，Baiyin City，Gansu Province，China）

【Abstract】The law of operation is a very important teaching content in elementary school. It is very important for elementary school students to master the correct operation method and operation law. For elementary school students who are new to mathematical operations，the law of operation may be more difficult to understand. To make pupils remember and master the law of operation，teachers need to adopt special methods，such as situational teaching method and group cooperative teaching method. At the same time，the primary school mathematics classroom should pay attention to the cultivation of students' verbal arithmetic ability，be more patient and careful，help students apply the laws of mathematical operations more effectively，and improve their ability to solve mathematical problems. This article describes the following elaboration on the new method of exploring and optimizing the teaching of the law of mathematical operations in primary schools.

小学数学运算定律是小学生数学学习的基础，是教学过程中十分重要的教学内容之一，但是对于小学生而言，运算定律较为抽象，难以理解，所以教师要选择更加有效的教学方式来帮助学生进行运算定理的理解和掌握，不仅如此，为了更好的加强小学生对于运算定律的学习，教师同时要在课堂教学中增加口算方面的技巧讲授，多管齐下，使数学运算定律教学更高效。

1.重视学生口算能力的培养

数学计算以口算为基础，也是运算定律的重要环节，学生在没有教师的指导下，进行口算训练，基本上用到的是笔算法则，他们会结合问题内容，在脑海中构建数学体系，列出算式最终求出结果。在这样的过程中，学生往往认为口算并没有笔算便捷，而且很容易出现错误，从而逐渐对口算训练失去兴趣。……
