《义务教育数学课程标准(实验稿)》中提出:“在‘图形与几何’的学习中,应帮助学生建立空间观念。”空间观念是指根据物体特征抽象出几何图形,根据几何图形想象出所描述的实际物体;能够想象出空间物体的方位和相互之间的位置关系;根据语言描述或通过想象画出图形等。
“Compulsory Education Mathematics Curriculum Standard (experimental draft)” put forward: “In the” graphics and geometry, “the study should help students to establish the concept of space.” Space concept refers to the geometric characteristics of the abstract according to the object, according to the geometry Imagine the actual objects described; We can imagine the orientation of the space objects and the positional relationship between them; According to the language description or the imagination to draw graphics.
