在初中阶段,图形与几何是数学课程中的重要内容,这部分内容主要涉及现实世界中的物体,几何体和图形的形状、大小、位置关系及其变换,它是学生更好地认识和描述生活空间的重要工具,帮助学生逐渐建立空间观念,积累几何活动经验,注重培养学生的几何直观与推理能力,从空间形式的视角更准确清晰地认识、描述、把握现实世界。
In the junior middle school, graphics and geometry are the important contents of mathematics course. This part mainly deals with the shape, size, position and transformation of objects, geometries and figures in the real world. It is a way for students to better understand and describe life Space is an important tool to help students gradually establish the concept of space, accumulation of experience in geometric activity, focusing on developing students’ geometric intuition and reasoning ability, more accurate and clear understanding, description and grasp of the real world from the perspective of spatial form.
