数学运算能力是小学数学要培养的一项最主要的基本能力。低年级学生运算错误的原因主要是注意力分散、感知粗浅、思维定势、口算不扎实、忽略算理、不良的学习习惯。要减少运算错误,应该强化口算训练,打好运算基础;加强估算教学,提高运算准确性;精心设计情境,激发运算兴趣;加强算法教学,重视数理探究;建立错题库,提高运算正确率;培养良好习惯,形成运算技能。 Mathematical computing ability is one of the most important basic skills in primary school mathematics. The reasons for the low grade students’ miscalculation are mainly distracting, superficial perception, fixed thinking, poor comprehension, ignorance of arithmetic and bad study habits. To reduce the calculation error, we should strengthen the port arithmetic training, lay the foundation for the operation; strengthen the teaching of estimation, improve the accuracy of the operation; elaborate the situation and stimulate the interest of the operation; strengthen the algorithm teaching, pay attention to the mathematical inquiry; Good habits, forming computing skills.
