小学数学新课程改革标准中明确指出:“小学数学在提高人的推理能力、抽象能力、想象能力和创造能力等方面有独特的作用。”这就明确要求在小学数学教学活动开展中,教师要注重对学生计算能力的培养,从口算、笔算、简算等方面对学生进行数学计算训练。但是在当前的小学数学计算活动开展中,我们发现,许多小学生的计算能力不尽如人意,在计算的时候常常是错误百出,这种情况已经成为数学计算的一种“常态”。数学本身就是一门以计算为基础的学科,数学计算错误成为影响学生数学发展的主要障碍。因此,在小学数学教学活动开展中,教师需要注重对学生数学计算的指导,加强计算,提高学生的计算水平。
The standard of primary school mathematics new curriculum reform clearly states: “Primary school mathematics plays a unique role in improving people’s reasoning abilities, abstract abilities, imagination abilities and creativity.” “This explicitly requires that in primary school mathematics teaching activities, Teachers should pay attention to the cultivation of students’ computing abilities, and carry out math calculation training on students from the aspects of math, pen calculation and simple calculation. However, in the current elementary mathematics calculation activities, we find that many primary students are not so good at computing ability and are often mistaken in calculation. This situation has become a ”normality " in mathematical calculation. Mathematics itself is a computing-based discipline, mathematical errors have become the main obstacle to the development of students’ mathematics. Therefore, in the primary school mathematics teaching activities, teachers need to pay attention to the guidance of the students mathematical calculations, to strengthen the calculation, improve the level of student computing.
