摘要
《全日制义务教育数学课程标准》(2011年版)提出十大核心概念,将数感摆在首要地位,其中还包括运算能力。在数感教育的价值问题上,我国学者普遍地认为数感的培养有助于学生数学的理解和解释现实问题,有助于学生发展心算、估算等技巧。本文从以下几点浅析如何在速算教学训练中培养数感。
"Mathematics curriculum standards for full-time compulsory education"(2011 Edition)puts forward ten core concepts,which put number sense in the first place,including computing ability.In terms of the value of number sense education,Chinese scholars generally believe that the cultivation of number sense is helpful for students to understand and explain practical problems in mathematics,and to develop mental calculation and estimation skills.This paper analyzes how to cultivate the sense of number in the teaching and training of quick calculation from the following points.
