小学生数感培养的几点思考──以“分数的再认识(二)”一课为例

Some Thoughts on the Cultivation of Pupils’ Sense of Numbers——Taking the Lesson “Recognition of Fraction(2)” as an Example

建立数感、培养数感对学生的数学素养发展具有重要意义。文章以《小学数学(五年级上册)》(北京师范大学出版社)"分数的再认识(二)"一课为例,通过学生一系列动手操作,让学生进一步理解分数的产生过程,了解分数与整数、分数与小数之间的联系,为培养学生的数感奠定扎实的基础。

The cultivation of number sense is of great significance to the development of students’ mathematical literacy. This article takes the lesson"recognition of fraction(2)"of grade 5 mathematics published by the Beijing Normal University Press as an example. Through a series of hands-on operations inclass,students can further understand the meaning of fractions,the relationship between fractions and integers as well as the relationship between fractions and decimals,which lays a solid foundation for cultivating students’ sense of numbers.
