数感作为一种主动、自觉的理解数和运算数的态度与意识,是建立明确的数概念和有效地进行计算等数学活动的基础,是将数学与现实问题建立联系的桥梁。那么,我们怎样在数学教学中培养学生的数感呢?一、着力帮助学生建立数概念理解数的意义,既可以通过组成理解数的大小和多少来加强对数的感知,又可以联系生活实际,在抽象的数和具体的量有机结合中进一步理解数的意义。在课堂教学中,
As a kind of initiative and conscious understanding of the attitude and awareness of numbers and operands, sense of number is the basis for establishing a clear concept of numbers and for conducting mathematical activities such as calculations efficiently. It is also a bridge connecting the mathematics with the reality. So, how do we cultivate the sense of number of students in mathematics teaching? First, focus on helping students to establish the meaning of the number of concepts to understand the number, both by understanding the size and number of numbers to enhance the perception of the logarithm, but also contact the actual life , The number of abstract and the specific combination of quantitative understanding of the significance of the number. In classroom teaching,
