数感是学生在学习数学过程中必须掌握的一种基本素养,它是学生认知数学的一种意识,也是学生是否主动、是否自觉地理解数学的态度。数感来源于数学教学,它是将数学的数概念与实际生活相联系的桥梁,也是学生可以有效进行数学计算,形成数学素养和数学技能的基础。《数学课程标准》指出:“数感主要表现在:理解数的意义;能用多种方法来表示数;能在具体的情境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
Sense of the number of students in mathematics learning process must grasp a basic literacy, which is a cognitive cognition of students, but also whether the students take the initiative, whether or not to consciously understand the attitude of mathematics. The sense of number comes from mathematics teaching. It is a bridge that connects the concept of mathematics with real life. It is also the basis for students to carry out mathematical calculation effectively and form mathematical literacy and math skills. Mathematical Curriculum Standard states: ”Sense of number mainly in: the significance of understanding the number of; can use a variety of ways to represent the number; can grasp the relative size of the relationship between the number of situations; can use the number to express and exchange information ; Can choose the appropriate algorithm to solve the problem; can be estimated
