空间与人类的生存和居住密切相关,了解、探索和把握空间,能使人类更好地生存、活动和发展。培养初步的空间观念是发展空间想像力的基础,是小学几何初步知识教学中的一项主要任务。《课程标准》目标中指出:在数学学习中,要丰富学生对现实空间及图形的认识,建立初步的空间观念,发展形象思维。而在现实的学习活动中,学生往往缺乏的就是空间观念,儿何知识的学习成为他们学习的难点,“空间观念”这一部分知识成为 Space is closely related to the living and living of human beings. Understanding, exploring and grasping the space can make human beings better survive, move and develop. To cultivate the initial concept of space is the basis for the development of spatial imagination and is a major task in the elementary knowledge teaching of elementary geometry. The goal of “Curriculum Standard” states: In mathematics study, it is necessary to enrich students’ understanding of real space and graphics, establish preliminary spatial concepts and develop image thinking. In the real learning activities, students often lack of space concept, knowledge of children and children become their learning difficulties, “space concept ” this part of the knowledge to become
