培养学生正确、迅速的计算能力是小学数学教学的基本任务之一,但在实际学习中,小学生计算的正确率常受到学生的兴趣、态度、意志、习惯等因素的影响。首先,我就学生的表现简单来分析一下学生计算出错的原因。第一,学习目的不明确,态度不端正,学习上马马虎虎,粗心大意,敷衍了事。如:把运算符号看错了:加号看成乘号,除号看成减号或把两位小数看成一位小数等。第二,100以内进退位加减法口算不熟练,对乘法 The training of students’ correct and rapid computing ability is one of the basic tasks in elementary mathematics teaching. However, in practical learning, the accuracy of primary school students’ calculation is often influenced by students’ interests, attitudes, wills and habits. First of all, I analyze the students’ performance simply to analyze the reasons why students calculate the error. First, the purpose of learning is not clear, the attitude is not correct, learning so-so careless, careless, perfunctory. Such as: the arithmetic symbol wrong: plus sign as a multiplication sign, the division number as a minus sign or two decimal places as a decimal and so on. Second, the addition and subtraction within 100 plus or minus the mouth is not skilled, multiplication
