《全日制义务教育数学课程标准》在知识与技能目标中明确指出:“学生要掌握必要的运算能力。”计算存在于数学学习的每一个环节之中,新课程的教材也非常强调从计算的本身延伸数学的其他教学,如应用题教学。所以要想学好数学首先要学会计算,而且要算好。然而学生在做计算题时经常出现抄错题、漏题、运算粗心、不进行验算等情况,大大影响了计算的正确率,最终导致数学学习成绩的下降,这种现象在农村小学尤为突出。 Full-time compulsory education mathematics curriculum standards in the knowledge and skills of the target clearly states: “The students have the necessary computing power. ” Calculations exist in every aspect of math learning, the new curriculum materials are also very stressed Computation itself extends other teaching of mathematics, such as applied problem teaching. So if you want to learn mathematics, you must first learn to calculate it, and you should do it well. However, when students make calculation questions, they often copy the wrong title, omission, carelessness, not checking, etc., greatly affecting the accuracy of the calculation, eventually leading to a decline in math scores. This phenomenon is particularly prominent in rural primary schools.
