21世纪的第一个10年,HPM(History and Pedagogy of Mathematics,数学史与数学教学)进入中国,到了第二个10年,HPM受到了较多关注,数学史被越来越多地运用于课堂教学实践。然而,相较于中学,HPM视角下的小学数学教学实践还不够深入。原因是什么呢?数学史融入小学数学教学需要注意哪些问题?采取什么措施,小学数学教师才能开发出好的HPM课例?这些都是HPM视角下的小学数学教学亟待解决的问题。为了找寻问题 In the first decade of the 21st century, HPM (History and Pedagogy of Mathematics) entered China. By the second decade, HPM received more attention and the history of mathematics was increasingly used in Classroom teaching practice. However, compared with secondary schools, HPM perspective of primary school mathematics teaching practice is not deep enough. What is the reason? What should be paid attention to when mathematics history is integrated into mathematics teaching in primary school? What measures should be taken so that elementary mathematics teachers can develop a good HPM lesson? All these are problems to be solved in elementary mathematics teaching under HPM. In order to find the problem
