简便计算作为数学计算教学的重要组成部分,对培养学生数感,发展学生观察、分析问题的能力,提升学生思维品质发挥着重要作用。它能摆脱运算方法、顺序的约束,化繁为简,实现快速地计算。简算教学能培养学生细心观察、发现规律的能力,有助于训练学生的思维,提高计算效率。一、当前小学数学简算教学存在的主要问题(一)缺乏本质理解。教师在简算教学中过于重视机械的技能训练轻算理的分析,部分学生死记定律、机械套用公式,不利 Simple calculation as an important part of mathematics teaching, which plays an important role in cultivating students’ sense of number, developing students’ abilities to observe and analyze problems, and improving students’ thinking quality. It can get rid of computing methods, the order of the constraints, simplification, to achieve rapid calculation. Simple teaching can develop students ’ability to observe carefully and discover regularities, which helps to train students’ thinking and improve calculation efficiency. First, the current primary school mathematics simple teaching problems (a) the lack of essential understanding. Teachers in the simple teaching emphasis on mechanical skills training Lightweight analysis, some student law of death, mechanical formula, unfavorable
