七年级数学(北师大版)上册《丰富的图形世界》是初中生入学后学习数学的第一章,也是在小学认识的一些基本图形的基础上,从大量的生活中存在的图形入手,引出了立体图形与平面图形,使学生感受几何图形与我们的生活息息相关,并体验立体图形与平面图形的相互转化,从而初步建立空间观念,有着承上启下的特殊价值和认知序列上的特殊意义。以七年级数学(北师大版)上册《丰富的图形世界》为例,谈谈“图形与几何”内容教学的方法。 The seventh grade mathematics (Beijing Normal University Edition) Volume “rich graphics world” is a junior high school students to learn mathematics after the first chapter, but also on the basis of some of the basic graphics recognized in primary schools, starting from a large number of living graphics, It leads the students to feel the geometry is closely related to our life, and experiences the mutual transformation of the three-dimensional graphics and the graphics, so as to initially establish the spatial concept, which has the special value of inheritance and special significance in the cognitive sequence. In the seventh grade mathematics (Beijing Normal University Edition) Volume “rich graphics world”, for example, talk about “graphics and geometry ” content teaching methods.
