《数学课程标准》指出:“数感是人的一种基本素养,是人主动地、自觉地理解和运用数的态度和意识。”数感主要表现在:理解数的意义,能用多种方法来表示数,能在具体的情况中把握数的相对大小关系,能用数来表达和交流信息,能为解决问题而选择适当的算法,能估计运算的结果,并对结果的合理性做出解释。“由此可见,培养学生的数感是我们在数学课堂中的重要教学任务。笔者试从以下三个方面谈一谈培养学生数感的做法。一、融入生活,帮助学生建立数感我们要培养孩子良好的数感,就应让孩子体会到 ”Mathematical Curriculum Standard“ states: ”Sense of number is a kind of basic human quality, and it is the attitude and consciousness of people who actively and consciously understand and use numbers." Sense of number mainly displays in: understanding the meaning of numbers, A variety of ways to represent the number of cases in a specific situation to grasp the relative size of the relationship between the number can be used to express and exchange information can solve the problem and choose the appropriate algorithm to estimate the results of the operation and the results of reasonable Sex to explain. Thus, to cultivate the sense of number of students is an important teaching task in the math classroom.I try to talk about the following three aspects to cultivate the sense of number of students practice: First, into life, to help students build a sense of number we To develop a good sense of the number of children, we should let the children understand
