相遇问题是小学五年级数学应用题教学内容的一个重要的组成部分,这是行程问题的一种类型,既有它的特殊性又有它的广泛性。让学生正确地理解和掌握相遇问题的解题方法,不但能巩固行程问题的解题,方法,而且为今后学习工程问题打下基础,为达到此目的,我在教学相遇问题时紧紧抓住其解题的特点进行分析引导。1、找题目中的关键词语相遇辨别是非是一种匀速相向运动。相向而行是这种类型应用题的情节特点,速度和是这种类型应用题的数量特点,
Encounter problem is an important part of the teaching content of the fifth grade primary school mathematics application, which is a type of itinerary problem, both of its particularity and its extensiveness. To enable students to correctly understand and grasp the solution to the problem of encounter, not only to consolidate the problem-solving and methodological problems, but also to lay the foundation for the future study of engineering problems. In order to achieve this goal, I firmly grasp the problem of teaching encounter Problem-solving characteristics of the analysis and guidance. 1, to find the key words encountered in the title recognition is non-uniform movement of a uniform. Oppositeness is the plot characteristic of this type of application problem, the speed and quantity characteristics of this type of application problem,
