一、空间观念及其在小学数学中的作用在小学切实打好数学基础,不仅应使学生学习数以及数的四则运算,还应认识常见的几何形体,了解它们的特征,培养学生的空间观念。在几何初步知识的教学中发展学生的空间观念,是小学数学教学目的要求之一。空间是物质存在的一种客观形式,由长度、宽度、高度表现出来。空间观念是指在空间知觉的基础上形成的关于物体的形状大小,以及物体之间的距离、方位在人们头脑里留下的概括的形象。它属于表象。
First, the concept of space and its role in primary school mathematics Mathematical foundation in the primary school to lay a solid foundation, not only should enable students to learn the number and number of the four operations, but also recognize the common geometry, understand their characteristics, cultivate students' space concept . Developing the students' concept of space in the teaching of elementary knowledge of geometry is one of the requirements for the purpose of primary school mathematics teaching. Space is an objective form of material existence, manifested by length, width and height. The concept of space refers to the shape and size of the objects formed on the basis of spatial perception, and the distance between the objects and the general image of the orientation left in people's minds. It belongs to the appearance.
