【Abstract】The continuous development of modern social economy has put forward higher requirements for our country's education work.In primary school mathematics teaching,the rational application of the combination of numbers and shapes can effectively improve the teaching effect and strengthen the students' mathematics literacy.To ensure that students can participate in classroom teaching and promote the further development of modern education,educators must pay more attention to it.This paper first analyzes the characteristics of the combination of numbers and shapes,and then,on this basis,comprehensively explores the concrete application of the idea of the combination of numbers and shapes in primary school mathematics teaching,hoping to provide a richer theoretical basis for the specific work of its related personnel.

在小學阶段开展数学教学时,数形结合的应用具有极其重要的价值,教育人员需要对其进行深入研究,确保能够通过数形结合思想对学生进行更为有效的引导,提升课堂教学效率,为了进一步明确在小学数学教学过程中如何更为有效的应用数形结合思想,特此展开本次研究,希望能够推进我国现代教育事业的有效发展。
1.数形结合思想特点
其一为直观性,该特点主要是在图形上体现,在解答数学问题时,根据题目画出对应的图形,对图形和数字构建相对应的关系,利用直观图形形成现数学问题,可以使学生对其具有更为深刻的理解。通常情况下,小学阶段学生没有成熟的抽象思维,教师在具体进行课堂教学时,利用图形进行辅助教学,可以对学生思维能力进行科学培养。数形结合思想在数学教学中的合理应用,可以使学生同时从听觉和视觉两个方面获取知识,进而对相关知识加深印象。……
