小学数学“空间与图形”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,是人们更好地认识和描述生活空间并进行交流的重要工具。“空间与图形”的学习,不仅使学生获得有关基础知识和基本技能,而且要让他们亲历“操作、观察、猜想,并进行合情推理验证”的探究过程。 Primary Mathematics “Space and Graphics” mainly studies the shape, size, position and transformation of objects and geometric shapes in the real world. It is an important tool for people to better understand and describe the living space and communicate with each other. The study of “Space and Graphics” not only enables students to acquire basic knowledge and basic skills, but also enables them to experience the process of “operation, observation, conjecture, and reasoning and reasoning.”
