“空间与图形”是小学数学学习领域不可缺少的重要组成部分。数学《课程标准》提出:“几何学习最重要的目标是使学生更好地理解自己所生存的世界,形成空间观念。”在传统教学活动中,“空间与图形”课堂教学较普遍地存在着重结果、轻过程的现象,忽视学生自主探究、主动参与的过程。新教材充分关注到了这一点,提供了关于空间与图形的 “Space and Graphics ” is an indispensable part of primary school mathematics learning. Mathematical “curriculum standards” put forward: “The most important goal of geometric learning is to enable students to better understand their own living world, the formation of space. ” In the traditional teaching activities, “space and graphics ” classroom teaching There is a general phenomenon of the results, the process of light, ignoring the process of student self-exploration, take the initiative to participate. The new textbook takes full care of this and provides information about space and graphics
