空间与图形的教学是小学数学教学的重要组成部分,其内容主要涉及现实世界中的物体、几何体和平面图形的形状、大小、位置关系及其变换。与其他教学内容相比,这部分内容具有很强的实践性、直观性与操作性,无论是学生的学还是教师的教都显现出强烈的个性色彩。根据这部分内容的特点与学生认知发展的规律,结合我自己的教学实践,我尝试总结出了“空间与图形”的概念教学模式。一、由生活实物引入概念几何体和平面图形来自丰富的现实原型,因此,进行空间与图 The teaching of space and graphics is an important part of elementary mathematics teaching. Its contents mainly relate to the shape, size, position and transformation of objects, geometries and graphic in the real world. Compared with other teaching content, this part of the content has a strong practicality, intuitiveness and operability, both student learning and teacher teaching have shown a strong personality. According to the characteristics of this part of the content and the law of cognitive development of students, combined with my own teaching practice, I try to sum up the concept of “space and graphics” teaching mode. First, the concept of life introduced by the concept of geometry and graphic from a rich real-life prototype, therefore, the space and map
