“鸡兔同笼”这一类数学问题能够引导学生经历由形象思维到抽象思维过渡的心理体验,有利于学生数学能力的培养。从教多年,我对鸡兔同笼这一数学问题进行了多次探究,下面就解题的策略谈谈我的看法。列举法用列举法解决鸡兔同笼问题简单易行,我们可以用尝试的方法来解答该题。首先鸡兔共有35只,因此我们先要设定一个大概的数据,然后再做出相应的调整,这样列举的步骤才会尽可能地少一些。假设鸡有20只,兔有15只,那么共有脚100只(20×2+ Mathematical problems such as “chickens, rabbits and cages” can lead students to experience the psychological experience of the transition from the image thinking to the abstract thinking, which is good for the students' math ability cultivation. After many years of teaching, I have conducted many explorations on this math problem with chickens and rabbits. I will talk about my opinion on the solution to the problem. Enumerating Laws and Enumerations to Solve the Problem of Chicken and Rabbit in a Cage It is easy to solve the problem in a try. First of all, a total of 35 chicken, so we must first set a rough data, and then make the appropriate adjustments, so that the steps listed will be as less as possible. Suppose there are 20 chickens and 15 rabbits, then there are 100 rabbits (20 × 2 +)
