在《数学课程标准》中“图形与几何”部分的主要内容有:空间和平面基本图形认识,图形的性质、分类和度量,图形的平移、旋转,轴对称、相似和投影,平面图形基本性质的证明,运用坐标描述图形的位置和运动等。在“图形与几何”的教学中,要注重发展学生的几何直观,让学生更直观地理解空间与图形,“图形与几何”在数学学习过程中有着重要的意义和作用。一、发展空间观念1.形成空间观念。学生在学习“空间与图形”这一
The main contents of the “Graphics and Geometry” section of the “Mathematics Curriculum Standards” are: basic understanding of space and plane graphics, nature of graphics, classification and measurement, translation, rotation, axisymmetry, similarity and projection, The basic nature of the proof, the use of coordinates to describe the location and movement of graphics. In the teaching of “Graphics and Geometry”, we should pay attention to developing students’ geometric intuition, let students understand space and graphics more intuitively, and “Graphics and Geometry” have an important meaning and function in mathematics learning process. First, the concept of space 1. The formation of space concept. Students are learning “Space and Graphics ” this one
