《数学课程标准(2011年版)》指出:“数感主要是指关于数与数量、数量关系、运算结果估计等方面的感悟。建立数感有助于学生理解现实生活中数的意义,理解或表述具体情境中的数量关系。”要想在教学中培养学生的数感,就必须先要了解数感的具体内涵,只有充分了解并掌握了数感的内涵,才能把握学生的数感培养问题。对于小学生而言,数学学习就是不断与数打交道的过程,对于这个阶段的学生而言,数不可能与生活现象脱离联系,将生活问题转化为数学问题进行解答,这
“Mathematical Curriculum Standard (2011 Edition)” points out: “Sense of number mainly refers to the sentiment about the number and the quantity, the relation of the quantity, the estimation of the operation result, etc. The establishment of the sense of number helps the students to understand the meaning of the number in real life and understand Or to express the relationship between the number of specific contexts. ”In order to cultivate the sense of number of students in teaching, we must first understand the specific meaning of number sense, only to fully understand and grasp the meaning of the number of senses in order to grasp the sense of the number of students Develop problems. For pupils, mathematics learning is the process of constant dealing with numbers. For students in this phase, it is impossible to get out of touch with the phenomenon of life and translate life problems into mathematical problems to answer them.
