数学思想是数学教学的精髓,是学生将知识转化为能力的纽带,因此,在课程标准理念的指导下,作为数学思想成员之一的“数形结合”思想的渗透就显得十分必要,这不仅有利于提高学生的数学素养,而且为学生的终身学习和可持续发展奠定了基础。本文就数形结合思想在小学数学教学中的渗透方面谈谈自己看法。一、数形结合思想的内涵及重要性1.数形结合思想的内涵所谓的“数形结合”思想就是把数量关系与空间形式有机、和谐地结合起来,通过“以形助数”或“以数解形”的形式,即借助线段、矩形、数轴等图形或模型、学具等实物或具体的生活情形等事例将代数问题几何化,或者是以恰当的数量关系来表达图形中隐含的信息,将几何问题代数
Mathematical thinking is the essence of mathematics teaching and a link between students’ ability to transform knowledge into ability. Therefore, under the guidance of curriculum standards, it is necessary to infiltrate the idea of “mathematical combination” which is one of the members of mathematical thought. This is not only conducive to improving students ’mathematical literacy, but also lays the foundation for students’ lifelong learning and sustainable development. This article talks about his own opinion on the infiltration of mathematical and mathematical ideas in elementary schools. I. The Connotation and Importance of the Combination of Number-Shapes 1. The Connotation of Combination of Number-Shapes The so-called “combination of number and shape” means that the quantity and the space should be organically and harmoniously combined through “ ”Or “ in the form of number solution ”, that is, with the line, rectangle, number of axes and other graphics or models, school tools and other physical or concrete life events such as algebra problem geometry, or in an appropriate number of relationships To express the hidden information in the graph, the geometric problem algebra
