《小学数学》是九年义务教育小学阶段一门重要学科,通过数学教学要初步培养学生具有辩证唯物主义观点,对立统一观点,相互转化的观点等。同时要培养学生各项数学能力,而任何一项能力、一种品质都要依托某些知识的学习,某一公式的指导及运用等诸多实践中获得。笔者以圆锥体积的教学为例浅谈如下:一、演示实验,推导公式《圆锥体积》是九年义务教育小学六年级数学教学内容,通过这一知识教学,主要是培养学生动手操作能 Primary Mathematics is an important discipline in the nine-year compulsory education elementary school stage. Through mathematics teaching, students should have a tentative view of cultivating their students with dialectical materialist point of view and opposites point of view and mutual transformation point of view. At the same time to develop students’ mathematical ability, and any one ability, a quality must rely on some knowledge of learning, guidance and use of a formula and many other practices obtained. I conical volume of teaching as an example to talk about as follows: First, the demonstration experiment, derive the formula “conical volume” is the ninth grade compulsory education sixth grade mathematics teaching content, through this knowledge, mainly to develop students hands-on
