在平日的解题训练中,有意进行一题多解,数法并用,织“法”成网,串“解”成链,小“题”大做,借“题”发挥,可以起到培养发散思维能力,提高创新能力.众方位,多角度,全视野,认真对待一道题,还可以培养同学们学习数学的兴趣,提升同学们的数学思维品质.本文仅举一例,供读者细细体会 In the problem-solving training on weekdays, you are interested in doing more than one question, using multiple methods, and weaving “methods” into a network, stringing “solutions” into chains, and “small questions” making great efforts. Divergent thinking skills, improve the ability to innovate. Azimuth, multi-angle, full vision, a serious problem, but also can cultivate students interest in learning mathematics, improve the quality of students’ mathematics thinking. This article just give one example, for the reader to experience
