空间思维是指对物体和几何图形的形状、大小、位置关系及其变化的直觉想像,能让人们正确认识和描述生活空间并进行交流。小学数学课程标准中指出:“空间思维主要表现在‘能由实物的形状想象出几何图形,由几何图形想象出实物的形状,进行几何体与其三视图、展开图之间的转化;能根据条件做出立体图形或画出图形;能从较复杂的图形中分解出基本的图形,并能分析其中的基本元素及其关系;能描述实物或几何图形的运动和变化;能采用适当的方式描述物体间的位置关系;能运用图形形象地描述问题,利用直观来进行思考。’”不难看出,培养学生的空间观念是促使小学生能更好地认识、理解生活的空间,更好的认知世界。
Space thinking refers to the intuitionistic imagination of the shape, size, position and change of objects and geometric shapes, allowing people to correctly understand and describe the living space and communicate with each other. Primary mathematics curriculum standard states: "thinking in space mainly in the ability to imagine from the physical shape of the geometric figure, the shape of the physical image from the geometry, geometry and its three views, expand the conversion between the picture; according to the conditions Make three-dimensional graphics or draw graphics; can be decomposed from more complex graphics basic graphics, and can analyze the basic elements and their relationships; can describe the physical or geometric movement and changes; can be described in an appropriate manner It is not difficult to see that cultivating students’ space concept is to encourage pupils to better understand and understand the space of life and to better recognize Know the world.
