小学阶段的几何初步知识比较分散,毕业总复习时,教师要注意把知识集中归类,以便学生能系统地认识各种平面图形,立体图形的特征,熟练地掌握有关形体的周长、面积和体积的计算方法,并能灵活运用公式,解决实际问题。现先将小学几何初步知识归纳列表如下,然后作简要的说明,供教师在指导学生复习时参考。 The preliminary knowledge of geometry in the elementary school phase is scattered. When graduating, the teachers should pay attention to classify the knowledge so that the students can systematically recognize the features of various plane graphics and three-dimensional graphics and master the perimeters and areas of the relevant shapes. Volume calculation method, and can use formulas flexibly to solve practical problems. The elementary knowledge of elementary school geometry is first summarized as follows, and then a brief description is provided for teachers to refer to when they are instructing students to review.
