新课程标准对小学数学教学赋予了培养学生空间感、开发空间想象能力和空间理解能力的使命,同时新的教育理念也要求学校培养学生的创造能力,深化学生对基本概念的活化理解。通观小学数学教材,里面也灵活地应用了多种数学工具来帮助学生发展相关能力,其中方格图在图形的认识和理解方面应用最广。一、图示位置变换,有效启蒙空间感空间想象是建立在基本的距离感和方位感的基础之上的,苏教版小学数学教材,借助方格纸作为基本工具对学 The new curriculum standard gives primary school mathematics teaching the mission of cultivating students’ sense of space, developing space imagination ability and space comprehension ability. At the same time, the new education philosophy also requires schools to cultivate students’ creativity and deepen students’ understanding of basic concepts. Through the elementary mathematics teaching materials, there are also a variety of mathematical tools that are flexibly applied to help students develop relevant abilities. Among them, the grid graph is the most widely used in understanding and understanding of graphics. First, the iconographic position change, the effective enlightenment of space sense of space Imagination is based on the basic sense of distance and sense of orientation based on the Supiao version of primary school mathematics textbooks, with the use of graph paper as a basic tool for learning
