数感主要是指关于数与数量、数理关系、运算结果估计等方面的感悟.数学课程标准指出:建立数感有助于学生理解现实生活中数的意义,理解或表达具体情境中的数量关系.数学核心素养可以理解为学生学习数学应当达成的有特定意义的综合性能力,核心素养不是指具体的知识与技能,也不是一般意义上的数学能力.它的核心素养基于数学知识技能,又高于具体的数学知识技能.核心素养是在数学学习过程中形成的,具有综合性、整体性和持久性特点.
Sense of number mainly refers to the number and the number of mathematical relations, the calculation of the results of the perception of mathematics curriculum standards that: the establishment of sense of number helps students understand the meaning of the number of real life, to understand or express the relationship between the number of specific situations The core literacy of mathematics can be understood as the comprehensive ability of students with specific meanings that should be reached by mathematics learning, and the core literacy does not refer to specific knowledge and skills, nor is it a mathematical ability in the general sense.Its core literacy is based on mathematical knowledge and skills, and Higher than the specific knowledge and skills of mathematics.The core literacy is formed in the process of mathematics learning, with the characteristics of comprehensiveness, integrity and persistence.
