【教学内容】人教版《数学》六年级下册100页例1。【教材分析与目标定位】数学思考是进行数学推理训练的重要内容。基于我们对教材的理解,结合六年级学生现有知识基础和年龄特点,把教材中“研究6个点,8个点可以连成多少条线段”的问题情境改为“41个人,每两人握一次手,一共要握多少次?”通过创设情境,把生活中握手的问题抽象成数学问题,这样的引入来源于学生的生活经验,能激发他们的学习兴趣,引导运用知难而
【Teaching content】 People’s Education Edition “Mathematics” sixth grade next 100 Page Example 1. 【Textbook Analysis and Goal Positioning】 Mathematical thinking is an important part of mathematical reasoning training. Based on our understanding of teaching materials and the existing knowledge base and age characteristics of the sixth grade students, we changed the question situation of “6 points and 8 points can be connected into many lines” in the textbook to 41 persons, How many times do we hold a hand for every two people? "By abstracting the situation, abstracting the handshake problem in our life into a mathematical problem is derived from the students’ life experiences, which can stimulate their interest in learning and guide the use of the knowledge Difficult
