学生数感的发展不是一朝一夕的事。作为一名数学教师,不仅需要将“数感”贯穿于整个数学教育教学过程的始终,还要有意识地引导学生主动运用于日常生活之中。那么,低年级数学教师如何围绕发展学生数感,让学生经历充分的数数活动,在多样化的数数实践中加深对数概念的理解,在活动中发展学生的数感;如何在数数操作过程中发展学生的数感,提高操作活动的有效性呢?这一问题是我们一线教育工作者的研究重点,也是小学数学 The development of student number sense does not happen overnight. As a math teacher, we not only need to pass “number sense” throughout the whole process of math education and teaching, but also consciously guide students to take the initiative to use in daily life. So, how do the junior math teachers develop students’ sense of numbers around, let the students experience the full number of activities, deepen the understanding of the concept of logarithm in diverse practice of numbers and develop the sense of number of students in the activity; The development of students during the operation of the number of sense to improve the effectiveness of operational activities? This issue is the focus of our education workers, but also elementary mathematics
