一、空间与图形教学现状的困惑与分析《标准》安排了“数与代数”、“空间与图形”、“统计与概率”、“实践与综合运用”四个学习领域。“空间与图形”作为其中一个学习领域在小学数学中占有非常重要的位置,然而教学中“空间与图形”的内容向来是教师觉得学生最难理解、最难掌握的知识,从学生在四个学习领域中作业和检测的掌握情况来看,“空间和图形”是最薄弱的一个领域,其主要原因是受小学生空间观念和空间想象力的制约,
I. Perplexity and Analysis of the Present State of Space and Graphics Teaching The Standard arranges four numbers of “number and algebra”, “space and graph”, “statistics and probability”, “practice and comprehensive utilization” Learning area. As one of the learning areas, “Space and Graphics” occupies a very important place in primary school mathematics. However, the content of “Space and Graphics” in teaching has always been the most difficult and difficult-to-grasp knowledge that teachers think students have. Students in the four fields of study operations and testing grasp the situation, “space and graphics ” is the weakest area, the main reason is subject to space concepts and spatial imagination constraints,
