在小学数学练习中,为了突出数学知识的重点、难点,教师可有意识地设计易产生思维偏差的练习题,诱导学生误入“圈套”,落入“陷阱”,而后促其反思、剖析、矫正,化错为利,从而更加深刻地领悟数学知识,以利形成准确、灵活的解题技能,促进思维发展。 In primary school mathematics exercises, in order to emphasize the key and difficult points of mathematics knowledge, teachers can consciously design exercises that easily lead to deviation of thinking, induce students to misunderstand “trap” and fall into “trap” and then promote their reflection, analysis and rectification , The wrong is the benefit, so that a deeper understanding of mathematical knowledge, in order to facilitate the formation of accurate and flexible problem-solving skills to promote the development of thinking.
