一、从现实生活中感受具体几何体,培养学生的空间观念学生对几何图形的认识来自于学生的现实生活。学生空间观念的培养首先要从学生的生活实际入手,创设一定的数学生活情境引导学生感知、理解实物,引导学生在摸一摸、量一量、议一议的过程中探索图形的特征,使学生在头脑中建立生活中实物的表象,形成初步的空间观念。从学生的生活经验出发,引导学生把生活中对图形的感受与空间存在的几何图形建立联系,培养了初步的空间观念。 First, feel the concrete geometry from the real life, cultivate the students’ space concept Students’ understanding of the geometry comes from the students’ real life. Firstly, we should start from the actual life of students and create a certain mathematical life situation to guide students to perceive and understand the real objects, to guide students to explore the characteristics of graphics in the process of touch, quantity and discussion Students in the mind to establish the appearance of life in kind, forming a preliminary space concept. Starting from the student’s life experience, the students are guided to relate their feelings in the life to the geometrical figures existing in the space and cultivate the initial space concept.
