数学主要研究的数量关系和空间形式的科学。空间形式在我们的教学中主要体现在“空间与位置”的学习中,小学阶段的关于空间形式的教学对学生的空间观念的形成十分重要。在课程标准中对空间观念进行了如下的阐述:“空间观念主要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,想象出物体的方位和相互之间的位置关系,描述图形的运动和变化,依据语言的描述画出图形等。”对于以直观形象为主的小学低年级学生来说,如何展开空间与图形的教学呢?
The main relation between mathematics and the spatial form of science. Spatial forms are mainly reflected in the study of “space and position” in our teaching. The teaching of space form in elementary school is very important to the formation of students’ space concept. The concept of space is described as follows in the curriculum standard: “The concept of space mainly refers to abstracting geometric shapes according to the characteristics of objects and imagining the actual objects described according to the geometric shapes, and imagining the positions and mutual positional relationships of the objects , Describe the movements and changes of graphics, draw graphics based on language descriptions, etc. ”How to expand the teaching of space and graphics for the lower primary students who are mainly visual images?
