[教学内容]人教版数学四年级下册P117例1及相关练习题。[教材简析]“植树问题”是人教版数学四年级下册第八单元“数学广角”的内容。数学广角主要是通过简单的实例渗透一些重要的数学思想方法,让学生在解决这些问题的过程中能主动尝试从数学的角度运用所学知识和方法寻找解决问题的策略,培养学生解决实际问题的实践经验和能力,激发学生对数学的好奇心和求知欲,增强学生学习数学的兴趣。[教学设计]1.学问在手中。这节课的内容并不陌生,因为生活中经常见到,难点就是使学生理解间隔数跟节点之间的关系,如何突破这个瓶颈,让学生轻松愉快掌握这个知识呢?我
[Teaching content] PEP Teaching mathematics fourth grade P117 cases and related exercises. [Textbook analysis] “tree planting problem ” is the fourth unit of the fourth edition of the PEP Teaching eighth unit “mathematical wide angle ” content. Wide angle of mathematics is mainly through a simple example of infiltration of some important mathematical ideas and methods so that students in the process of solving these problems can take the initiative to try from the mathematical point of view using the knowledge and methods to find a solution to the problem of strategies to develop students to solve practical problems Practical experience and ability to stimulate students curiosity and curiosity in mathematics and enhance students interest in learning mathematics. [Teaching design] 1 learning in hand. The content of this lesson is no stranger to one another. Because it is often seen in life, the difficulty is to make students understand the relationship between the number of nodes and intervals. How to break this bottleneck so that students can feel relaxed and happy about this knowledge?
