“空间与图形”是《小学数学课程标准》安排的四个学习领域之一。在小学阶段的数学教学中,有很多关于平面图形和立体图形的知识。根据小学生的年龄特点,其知识分布在各个学段。因此,我将小学阶段的平面图形与立体图形知识集于一体,制作了“平面.立体”多用演示板,适用于1～5年 Space and Graphics is one of four areas of study scheduled for Primary Mathematics Curriculum Standards. In elementary school mathematics teaching, there is a lot of knowledge about plane graphics and stereo graphics. According to the age characteristics of primary school students, their knowledge is distributed in various sections. Therefore, I put the elementary graphic and three-dimensional graphics knowledge in one set, produced a “flat. Three-dimensional” multi-purpose demonstration board for 1 to 5 years
