小学几何形体知识中有些概念的揭示、公式的推导，是用实验的方法进行的。教学时，针对小学生的年龄特点和好奇爱动的心理特征，多让学生自己实验，动脑动手，有利于强化对概念的认识，深化对公式的理解。同时，通过实验也有利于学生发现几何形体的性质、特征，找到一些较抽象问题的解题方法。一、通过实验，有利于学生认识概念的本质属性。几何形体中一些容易混淆的概念，或者是比较抽象的概念，教学时，让学生自己动手做实验，有利于学生认识概念的本质属性，搞清它们之间的区
The discovery of some concepts in elementary geometry knowledge and the derivation of formulas are conducted experimentally. Teaching, the age characteristics of primary school students and curious love moving psychological characteristics, let students experiment, brain, help to strengthen the understanding of the concept, deepen the understanding of the formula. At the same time, it is also beneficial for students to discover the nature and characteristics of the geometry through experiments, and to find some solutions to the abstract problems. First, through experiments, is conducive to students to understand the essential attributes of the concept. Some confusing concepts in geometry, or abstract concepts, allow students to do their own experiments while teaching, which helps students to understand the essential attributes of concepts and clarify the relationship between them
