摘　　要：《义务教育数学课程标准(2022年版)》强调,落实核心素养须构建、强化具有结构化特征的课程内容设计。学科大概念是结构化课程设计核心,能引领组织教学内容,体现学科本质,帮助学生深层理解知识。本文探讨大概念视角下的数学教学:先准确阐述学科大概念内涵,再以“小数乘法”单元为例,阐述整体教学设计流程及学科大概念如何统领教学,最后分析总结该单元教学特色、创新及效果,为学生数学核心素养发展奠定基础。The Mathematics Curriculum Standards for Compulsory Education(2022 Edition)emphasizes that the key to implementing core literacy lies in constructing and strengthening the curriculum content design with structural characteristics.The big ideas of the discipline are the core of structural curriculum design,which can lead and organize teaching content,embody the essence of the discipline,and help students understand knowledge in depth.This article explores mathematics teaching from the perspective of big ideas.Firstly,it accurately expounds the connotation of big ideas of the discipline.Then,taking the“decimal multiplication” unit as an example,it elaborates the overall teaching design process and how big ideas of the discipline guide it.Finally,it analyzes and summarizes the characteristics,innovations and effects of the unit teaching,laying afoundation for the development of students’core mathematics literacy.
