计算不仅是学生重要的数学能力,而且是发展学生思维的有效载体。“数与代数”作为数学新课程教学内容的四大领域之一,贯穿于小学数学教学的全过程,本身就说明计算素养对于学生发展之重要。学生的数学思维在系统的计算教学中能够得到充分的发展,有利于形成稳定的心理和良好的习惯。新课程实施以来,计算课堂教学充满了生机和活力。但计算正 Computation is not only an important mathematical ability of students, but also an effective carrier for developing students’ thinking. “Number and Algebra” as one of the four major areas of the teaching content of the new mathematics curriculum runs through the entire process of primary school mathematics teaching, which in itself illustrates the importance of calculating literacy for the development of students. Students’ mathematical thinking can be fully developed in the system of computational teaching, which is conducive to the formation of stable psychology and good habits. Since the implementation of the new curriculum, calculating classroom teaching is full of vigor and vitality. But calculate positive
