量的计量是小学数学基础知识的一个重要组成部分。主要包括量、计量、计量单位和名数等。这些内容分散地编排在二年级至六年级的教材里。几乎贯穿于整个小学数学的教学当中。在量的计量里,计量单位是教学的重点和难点。如何在教学中使学生对这方面的知识有一个清醒的认识,较好地掌握计量单位之间的进率、互相转化呢?不妨在教学实践中实行三步走:建立观念、理解联系、揭示规律。一、建立观念观念是人们对客观事物的概括形象的认识,是一种浅层次的 Measurement is an important part of elementary school mathematics. Including the amount, measurement, measurement units and names and so on. The content is distributed in grades two through six. Almost throughout the entire primary school mathematics teaching. In the measurement of quantity, the unit of measurement is the teaching of the key and difficult. How to enable students to have a clear understanding of this knowledge in teaching, to better grasp the rate of progress among the units of measurement, and transform each other? Three steps in teaching practice may be: to establish the concept, to understand the link, reveal law. First, to establish the concept of concept is the people’s understanding of the general image of objective things, is a shallow
