数感是学生对“数”的敏感、精确、丰富的感悟,《数学课程标准》明确指出:“在数学课程中,应当注重发展学生的数感”。因此培养学生的数感是当前数学教学的一个重要任务。作为数学老师,在传授数学知识的过程中,让学生去体验现实生活,启蒙数感;让学生学会观察,建立数感;学生间合作交流,形成数感;动手实践操作,增强数感;质疑反思,发展数感,从而进一步提升学生学习和综合运用数学的能力。
Sense of number is the students “number ” sensitive, precise, rich insights, “Mathematics Curriculum Standards” clearly states: “Mathematics in the curriculum, should pay attention to the development of the sense of the number of students ”. Therefore, to cultivate students’ sense of number is an important task in current mathematics teaching. As a math teacher, in the process of teaching mathematics knowledge, let students experience real life, enlightenment sense of numbers; let students learn to observe and establish sense of number; cooperation and exchange between students to form a sense of number; hands-on practice to enhance the sense of number; questioned Reflection, the development of a sense of number, so as to further enhance the ability of students to learn and comprehensive use of mathematics.
