近几年从事低年级数学教学,我发现,口算教学在低年级占有较大的比重,特别是一年级,没有出现笔算的形式,一年级是打好口算基础的重要时期,小学数学新课程标准也提出,培养学生的计算能力,首先要重视基本的口算训练,口算既是笔算的基础,也是计算能力的重要组成部分。口算教学,不仅是提高计算能力的过程,更是学生思维、心智的训练过程。要提高学生的计算能力,必须打好口算这个基础,口算能力的高低将直接影响到学生中、高年级计算能力 In recent years engaged in mathematics teaching in the lower grades, I found that oral arithmetic occupies a large proportion in the lower grades, especially the first grade, did not appear in the form of pen and pound, the first grade is an important period to lay a good foundation for mathematics, mathematics new curriculum standards Also proposed that to develop students’ computing ability, we must first pay attention to the basic port training, accounting is not only the basis of calculation, but also an important part of computing power. Mouth arithmetic, not only to improve the computing power of the process, but also the students thinking, mental training process. To improve the computing power of students, we must lay the foundation for this calculation. The ability of numeracy will directly affect the middle and upper grades of students
