小学数学课程中的空间几何学习,被概括为“图形与几何”。它是小学数学学习领域不可缺少的重要内容,主要研究现实世界中的物体和几何图形的形状、大小、位置关系及其变换等。学生在已有的知识和经验之上,通过观察与操作、比较与分析、抽象与概括、推理与判断等活动,发展空间观念、几何直观、推理能力、应用意识和创 Spatial geometry learning in elementary mathematics is generalized as “Graphics and Geometry.” It is an indispensable and important part in primary school mathematics learning. It mainly studies the shape, size, position and transformation of objects and geometries in the real world. Students develop spatial concepts, geometric intuition, reasoning ability, application awareness and creativity through activities such as observation and operation, comparison and analysis, abstraction and generalization, reasoning and judgment based on the existing knowledge and experience
