一、背景分析“数学广角——田忌赛马”是人教版实验教材四年级上册的内容,它从《田忌赛马》的故事引入对策的应用问题,通过这个故事让学生体会对策论方法在实际中的应用。《田忌赛马》的故事学生可能已经了解,但大都并不是从数学的角度去理解的。为此,我们制定了如下教学目标:(1)了解《田忌赛马》 First, the background analysis “Mathematical Wide Angle - Tianji horse racing ” is the content of the fourth grade of the PEP experimental teaching book, which introduces the application of countermeasures from the story of “Tian Ji horse racing”, through which students can experience the method of game theory Practical application. The story of “Tian Ji horse racing” students may already know, but most are not understood from the mathematical point of view. To this end, we have formulated the following teaching objectives: (1) understanding “Tian Ji horse racing”
