大数学家、科学家牛顿曾说过:“在数学上,例子比法则更重要。”鸡兔同笼这一古老的数学问题最早见于《九章算术》,可谓家喻户晓,妇孺皆知。在新课程推进的今天,鸡兔同笼问题出现在数学教科书“解决问题的策略”这一章节,使解法条理化、系统化,更易于学生接受、理解和应用。例:我国古代数学著作《孙子算经》中有“鸡兔同笼”问题:“今有鸡兔同笼,上有三十五头,下有九十四足,问鸡兔各几何?”一、列举法 Newton, a great mathematician and scientist, once said: “Mathematically, examples are more important than laws.” The oldest mathematics problem of chickens and rabbits was first seen in “The Chapter Nine Arithmetic” and it is well-known to everybody. Today, with the advancing of the new curriculum, the problem of chickens and rabbits appears in the section of Mathematical Textbook “Strategies for Problem Solving” to make the solution systematic, systematic and easier for students to accept, understand and apply. Example: In ancient Chinese mathematics book “The Sun Tzu”, there are “chicken with rabbit cage” question: “Now there are chickens in the same cage, there are thirty-five, there are ninety-four feet under the chicken Geometry? ”First, enumeration Act
