“一题多解”就是启发和引导从不同角度、不同思路,运用不同的方法和不同的运算过程,解答同一道数学问题,即由多种途径获得同一数学问题的最终结论.一题多解能提高综合运用已学知识解答数学问题的技能技巧,锻炼思维的灵活性,开阔解题思路,能更好地掌握知识间的纵横联系.举一例如下. “One problem and many solutions ” is to inspire and guide from different angles, different ideas, the use of different methods and different computing processes, to solve the same math problem, that is, by a variety of ways to get the final conclusion of the same mathematical problem. Multi-solution can improve the comprehensive use of knowledge learned to solve mathematical problems skills, exercise flexibility of thinking, broaden the problem-solving ideas, to better grasp the vertical and horizontal linkages of knowledge.
