“空间与几何”被新课标列为十大核心概念之一.其“核心”意义至少有两个方面:从学科角度看,数学是研究空间形式和数量关系的科学.“空间与几何”作为数学三大领域之一,共同架构起数学知识体系,孕育思想方法.而空间观念又是学习这一领域的慧眼,为什么这么说?首先我们弄清什么是空间观念,简单地说就是对图形的数学看法和想法.它是发现与解决几何问题的数学思维先导.空间观念的品质决定解决几何问题的思维深度与广度.因而空间观念对学好数学具有 “Space and Geometry” has been listed as one of the ten core concepts in the new curriculum. Its “core” meaning has at least two aspects: from a disciplinary point of view, mathematics is the science that studies the relationship between spatial form and quantity. “Space and Geometry” is one of the three major areas of mathematics. It is a common framework for building a knowledge system of mathematics and gestation of ideas and methods. The concept of space is also a study of the eye of the field. Why do we say this? First, we understand what is the concept of space, Simply speaking, it is the mathematics view and idea of ​​the graph. It is the mathematical thinking that finds and solves geometric problems. The quality of the spatial concept determines the depth and breadth of the thinking to solve the geometric problem. Therefore, the spatial concept has the ability to learn mathematics.
