从小学数学考试试卷来看,每份试卷上计算题所占分值都在40分以上,而80%以上的学生计算题得不到满分,有的学生失分较多。其实,计算几乎渗透到一份试卷的每道题,特别是应用题,学生列式正确而因计算错误失掉分,十分令人惋惜。学生计算能力差,成为学生进一步学习数学知识的严重障碍。所以,提高学生 From the primary school mathematics exam papers point of view, each piece of paper on the calculation of the questions are accounted for more than 40 points, while more than 80% of the students did not calculate the full score, and some students lose more. In fact, it is regrettable that the calculation of almost every question in a test paper, especially the question of application, will result in the correct classification of students and the loss of points due to miscalculation. Students poor computing power, as students a serious obstacle to further learning mathematics. So raise the students
