小学几何初步知识的教学(形的教学),是使小学生打好数学基础的重要方面,它的意义在于培养学生的空间观念和初步的空间想象力。那么,如何在教学中实现这两个意义呢?下面谨就此谈些拙见。我们知道,空间观念是指在空间知觉的基础上形成的关于物体的形状、大小及其相互位置关系(方向、距离)的表象。由于小学生是以具象思维为主,抽象思维 The teaching of primary elementary geometry knowledge (form teaching) is an important aspect that enables pupils to lay a solid foundation of mathematics. Its significance lies in cultivating students' space concepts and initial spatial imagination. So, how to achieve these two meanings in teaching? Here are some humble opinions on this. We know that space concept refers to the appearance of objects' shapes, sizes and their mutual positional relationship (direction, distance) based on spatial perception. Because primary school students are based on the concrete thinking, abstract thinking
