虽然“田忌赛马”的故事早已家喻户晓,许多学生都通过父母或媒体对这个故事了然于胸,们在人们的心目中,如果“田忌赛马”的故事编入教材,一定是编入语文教材。因此,把“田忌赛马”的故事编入小学数学教材不能不说是一个创举(见人教版小学数学四年级(上册)数学广角之例4)。编者把“田忌赛马”的故事编入小学数学教材一定是看中了这则故事中所包含的数学思考,而绝非是仅仅为了让学生感知孙膑的智慧和灵活解决问题的策略。如果不弄清这则故事中所包含的数学教学价值,就会把这个例题上成语文课或者故事课。那么这则故事中到底包含了什么样的数学教学价值呢?经
Although the story of “Tian Ji Race Horse” has long been known to the public, many students know this story through their parents or the media. In the minds of people, if the story of “Tian Ji Race Horse” is compiled into a textbook, Into the language teaching materials. Therefore, the “Tian Ji horse racing,” the story into the primary school mathematics textbook can not be said to be a pioneering move (see People’s PEP Edition fourth grade mathematics mathematics wide-angle example 4). The editor of the “Tian Ji horse racing” story compiled into primary school mathematics textbooks must be fancied in this story contains mathematical thinking, but by no means only to enable students to perceive Sun Yong’s wisdom and flexible solution to the problem. If you do not understand the mathematical teaching contained in the story value, will this example into a language class or story class. So what exactly does this story include in mathematics teaching?
