见多就加,见少就减,是小学生解答应用题易犯的毛病。这反映了学生不是通过分析数量关系解决实际问题,而是凭题目中“多几”、“少几”等字词机械地决定用加法、减法。这会形成学生思维的惰性,阻碍智力的发展。因此,必须改进教学方法,防止这类毛病的发生。首先,在教学第二册“求一个数比另一个数多几(少几)”的应用题时,应作好孕伏。让学生特别注意弄清“谁与谁比”,“谁比谁多多少(或少多少)”,真正理解“甲比乙多几”就是“乙比甲 See more plus, see less to reduce, is a primary school students to answer questions of application easy to commit mistakes. This reflects that students do not solve practical problems by analyzing quantitative relationships, but instead mechanically decide on additions and subtractions by the words “more” and “less” in the title. This creates inertia in student thinking and impedes the development of intelligence. Therefore, teaching methods must be improved to prevent such problems.
