让解决问题的思路更“活”一些——由“鸡兔同笼”问题教学引发的思考

Let Problem-Solving Ideas More Live Some——Reflections on "Teaching Chicken with Rabbit Cage"

解决问题的策略是在解决问题的实践中形成的,解决问题时,要把实际问题转化成数学问题,要把数学问题转化成数学方法,让学生有更大的思考空间和活动平台,将已有的数学知识和生活经验紧密联系起来,那么他们的主动性、能动性将会更好地发挥出来,解决问题的思路才会越来越"活"。

The strategy for solving problems is developed in practice.When solving the problems,it is necessary to change the practical problem into mathematic problem,and change mathematic problem into practical problem,to let the students have a bigger thinking space and activity platform.By linking the mathematics knowledge gained to life experience closely,the students may better play their proactivity and initiative,and their train of thought for problem-solving will be more and more alive. Key words：solve the problem;strategy;mathematical thinking;train of thought
