培养学生的数感,是数学课程改革的重要理念,是数学教学的主要任务。因此,数感是一个人数学素养高低的标志之一。“数感”不是通过他人的传授而能够获得的,培养学生的数感,要在现实生活中建立数感,在自主探索中形成数感,在动手实践中领悟数感,在体验估算中发展数感,在解决问题中升华数感。 Nurturing the sense of number of students, mathematics curriculum reform is an important concept, mathematics teaching is the main task. Therefore, the sense of number is one of the signs of a person’s level of mathematical accomplishment. “Sense of number ” is not obtained through the imparting of others, to cultivate the sense of number of students, to establish a sense of number in real life, to create a sense of number in the independent exploration, in the hands-on practice to realize the number of senses, experience estimation In the development of a sense of number, to solve the problem of the number of sublimation.
