《义务教育数学课程标准》指出:“小学生要掌握必要的计算技能。”简便运算是小学数学计算能力的一个重要组成部分,是学生计算能力的综合体现。但在学生实际运算中,出现了各种各样的错误,严重阻碍了学生数学成绩的提高。所以,我们应该针对学生的错误类型及错误原因进行分析,发现其中的问题并对症下药,以下是我在平时教学工作中发现学生计算出错较多的一些问题:一、错误类型1.学习了减法的性质后,会出现以下错误:683原137原383=
The Standard of Compulsory Education Mathematics Curriculum states: “Primary school students need to master the necessary computational skills.” Convenient computing is an important part of primary school mathematics calculation ability and a comprehensive expression of students’ computing abilities. However, in the actual operation of students, a variety of errors have appeared, which seriously hindered the improvement of students’ math scores. Therefore, we should analyze the types of students and the reasons for the error to find the problems and the right medicine, the following is my usual teaching found that students calculate more errors some of the problems: First, the error type 1. Learning the subtraction After the nature, there will be the following error: 683 original 137 original 383 =
