培养小学生的数感是提升学生数学素养的重要基础,教师在教学过程中要创造性使用教材,开放性使用教材。多给学生提供一些动手观察、操作的机会,让学生在具体生活情境中感知数感,只实际操作中构建数感,在估算中加强数感。所谓数感,通俗讲就是学生对数的感觉,具体表现为对数和运算有敏锐的感受力,在日常生活中,有意识地、主动地从数学的角度把握问题中潜在的数学特征。培养良好的数感,是提高学生数学素养的标志。学生的数学素养并不能完全用计算能 Sense of raising pupils ’sense of numbers is an important foundation for improving students’ mathematical literacy. Teachers should creatively use teaching materials and open teaching materials during the teaching process. Give students more hands-on observation and operation opportunities, so that students can feel a sense of number in specific life situations. Only in practice can they build sense of numbers and sense of numbers in estimation. The so-called sense of number, popular talk is the sense of logarithm of the students, the specific performance of the logarithm and arithmetic have a keen sense of power, in daily life, consciously and actively take the math from the perspective of potential mathematical problems. Develop a good sense of the number of students is to improve the mathematical quality of the logo. Students’ mathematical literacy can not be completely calculated
