什么是数感呢?所谓数感是一个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,并为解决复杂问题提出有用的策略。也可以说数感是一种数学素养。《数学课程标准》明确要求“:教师在教学中要培养学生良好的数感”。那么什么是数感呢?所谓数感就是一种数学素养,就是一个人对数与运算的感觉、感受乃至感情,是对日常生活中的数与运算有敏锐的感受力,有意识地从数学的角度去观察、解释和表示
What is the sense of the number? The so-called number sense is a person’s general understanding of the logarithm and operation. This understanding can help people make mathematical judgments in a flexible way and put forward useful strategies for solving complex problems. It can also be said that a sense of mathematics is a mathematical quality. “Mathematics Curriculum Standards” clearly requires “: teachers in teaching students to develop a good sense of number ”. So what is the sense of the number? The so-called number sense is a mathematical literacy, that is, a person’s logarithm and operation of the feeling, feeling and even feelings, is the daily life of the number and operation of a keen sense of consciously from mathematics Point of view to observe, explain and said
