数学是研究空间形式的科学。空间与图形正是小学数学领域的一大重要内容。小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。它们是人们认识和描述生活空间、进行交流的重要工具。儿童的空间观念形成大致经历了这样几个阶段:具体、半具体、半抽象、抽象。可以看出小学生缺乏空间观念,空间想象能力较弱,因此在这部分内容教学时学生很不容易理解和掌握。利用信息技术教学,能直观、形象、生动地在学生面前展现空间图形知 Mathematics is a science that studies the form of space. Space and graphics are just a big part of elementary mathematics. Primary space and graphics The main study of objects and geometric shapes in the real world, size, location and its transformation. They are important tools for people to understand and describe the living space and communicate with each other. The formation of children’s space concept generally goes through several stages: concrete, semi-specific, semi-abstract and abstract. It can be seen that primary school students lack of space concept and their spatial imagination ability is weak, therefore students are not easy to understand and master when teaching this part. The use of information technology teaching, intuitive, vivid image in front of students to show the spatial pattern
