纵观整个小学数学教材,“数与计算”是条主线,又是最基础最重要的一部分知识,它直接影响着其他数学知识的学习,是整个小学数学教材的重点。计算是每个小学生必须掌握的一项基本技能。然而在平时的教学过程中,许多学生的计算正确率并不高。通过调查和分析,我发现除了一小部分学生因为算理、算法未真正掌握而导致错误外,很大一部分竟然与学生在计算过程中的一些不良习惯有关。这已成为困扰我们数学教学的重要问题。那么该如何 Throughout the entire primary school mathematics textbooks, “number and calculation” is the main line, but also the most basic part of the most basic knowledge, which directly affects the learning of other mathematical knowledge, is the focus of primary school mathematics textbooks. Calculation is a basic skill that every pupil must master. However, in the usual teaching process, many students calculate the correct rate is not high. Through the investigation and analysis, I found that except for a small part of students because of arithmetic, the algorithm did not really grasp the error, a large part of unexpectedly with the students in the calculation of some bad habits related. This has become an important problem plaguing our mathematics teaching. Then how?
