基于核心素养的小初衔接数学单元整体教学设计与实施——以立体图形为例

Design and Implementation of Mathematics Unit Teaching for Primary and Secondary School Connection Based on Core Literacy:Taking the Teaching of 3D Graphics as an Example

小学数学教育对学生数学思维和能力的早期发展至关重要,小学数学和初中数学的衔接既涉及学习内容上广度和深度的提升,也涉及学生思维从具象到抽象的转变。学段过渡时期,以核心素养为指向,进行大单元整体教学设计,可以将小学阶段碎片化的数学知识,借助大概念串成线、连成面,促进学生结构化知识的形成,锻炼数学思维,感悟数学思想,发展核心素养,进而帮助学生顺利过渡、有效衔接。

Primary school mathematics is crucial for the early development of students' mathematical thinking and abilities.The connection between primary school mathematics and junior high school mathematics involves not only the improvement of the breadth and depth of learning content,but also the transformation of students' thinking from concrete to abstract.During the transitional period of the academic stage,with the core literacy as the direction,the overall teaching design of large units can be carried out,which can connect the fragmented mathematical knowledge in primary school into lines and surfaces through the use of big concepts,promote the formation of structured knowledge for students,cultivate mathematical thinking,comprehend mathematical ideas,develop core literacy,and help students transit smoothly and effectively.
