论文部分内容阅读
“空间与图形”在小学数学中占有非常重要的位置,这部分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,它是人们更好地认识和描述生活空间并进行交流的重要工具。但是,由于小学生缺乏空间观念,空间想象能力较弱,要从实物中抽象出这些物体的特点,是比较困难的。那么,在教学实践中,我们如何培养学生的空间观念?下面浅谈自己的一些看法。一、从现实生活中提取素材,形成鲜明的表象
Space and Graphics occupy a very important position in elementary mathematics. This part mainly relates to the shape, size, position and transformation of objects, geometries and graphic shapes in the real world. It is a better understanding of people And describe the living space and communicate important tools. However, because pupils lack the concept of space and their spatial imagination is weak, it is difficult to abstract the characteristics of these objects from the real objects. So, in teaching practice, how do we cultivate students’ space concept? Here’s some of their own views. First, extract material from real life, a clear appearance
