几何是数学中一个非常重要的分支,小学的直观几何具有中学的论证几何无法取代的课程功效,图形与几何的知识又是相对抽象的,学生不易掌握。因此,立足深度学习,通过借助熟悉的生活材料,以核心问题为引导,开展观察、操作、分析、想象等活动,是发展学生空间观念的有效途径!下面以苏教版三年级下册“面积的认识”为例,谈谈如何立足深度学习、培养学生的空间观念和几何直觉能力。一、激活学生思维,直观感受面积“这个世界是几何的。”图形和几何的知识在生活中几乎都能找到其原型,就像车轮为什么要做成圆的,椅子摇晃了怎样用木条固定 Geometry is a very important branch in mathematics. The elementary geometry of the elementary school has the argument that the geometry can not be replaced by the middle school. The knowledge of the figure and the geometry is relatively abstract, and the students are not easy to grasp. Therefore, based on in-depth study, through the use of familiar living materials and guided by core issues, activities such as observation, operation, analysis and imagination are effective ways to develop the concept of student space. In the following, Area of ​​awareness “as an example, to talk about how to base on depth learning, cultivate students’ space concept and geometric intuition ability. First, activate the students thinking, intuitive feeling of area ”The world is geometric. " Graphics and geometric knowledge almost always find its prototype in life, just like the wheel why make a round, the chair shakes how to use wood Fixed
