实行新的课程标准之后,在计算能力方面对学生要求并没有太多变化,提高低年级学生的计算能力,依然是小学数学教学的重点之一,然而一个不容忽视的现实是学生的计算能力在不断下滑,特别是口算能力下滑严重,从而严重影响学生计算的准确性,更影响了学生后续学习数学的兴趣。每一次的考试之后,我们都能发现不少的学生错误在计算上,许多家长都说:“我的小孩子太粗心了,老是计算出错!”也有的学生在反思考试情况时说:“这次太粗心了,下次一定注意。”我想反思固然重要,然而找出根本原因才是最重要的。因此,提高口算能力在小学低年级数学教学中 After the implementation of the new curriculum standards, there is not much change in the students’ requirements in terms of computing power. Improving the computing power of students in lower grades is still one of the focuses of primary mathematics teaching. However, one of the most important realities that students can not afford to ignore is The declining trend, especially the decline in numeracy ability, seriously affected the accuracy of student calculations and affected students’ interest in further math. After each exam, we can find a lot of mistakes in the calculation of the students, many parents said: “My children are too careless, always make mistakes! ” Some students said in the reflection of the examination said : “This time is too careless, the next must pay attention. ” I think it is important to reflect on, but to find the root cause is the most important. Therefore, the ability to improve the numeracy in the lower primary mathematics teaching
