什么是数感?简单地说,数感是人对数与运算的一般理解,这种理解可以帮助人们用灵活的方法做出数学判断、为解决复杂的问题提出有用的策略。数感是人的一种基本的数学素养,它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,是数学与现实问题建立联系的桥梁。它是一种主动地、自觉地或自动地理解数和运用数的态度与意识。
What is a sense of number? In short, sense of number is a general understanding of human logarithm and operation, this understanding can help people make mathematical judgments in a flexible way, put forward a useful strategy to solve complex problems. Sense of number is a kind of basic mathematical accomplishment of human beings. It is the basis for establishing a clear concept of numbers and for conducting mathematical activities such as computation efficiently. It is also a bridge linking mathematics with practical problems. It is a kind of initiative and consciously or automatically understand the number and the use of the number of attitudes and awareness.
