数学知识具有严密的逻辑性和抽象性,而小学一年级学生仍是以具体形象思维占主导地位,逻辑思维尚处于萌芽阶段。如果沿用以往的传统教学模式,仅靠教师讲解和学生做书面练习的方法来学习,容易使学生对学习数学感到枯燥无味。笔者以一年级数学的重难点——加减运算为突破口,借助于小学生好玩、好动、好奇、好胜等心理特点,化难为易,变枯燥为有趣,收到了理想的效果。 Mathematical knowledge has strict logic and abstraction, and the first grade primary school students are still dominated by specific image thinking, logical thinking is still in its infancy. If you follow the traditional mode of teaching in the past, only by teachers and students to practice written methods to learn, easy to make students feel boring to learn mathematics. The author takes the first grade mathematics heavy and difficult point - the addition and subtraction operation as the breakthrough, with the help of pupils' fun, active, curious, aggressive and other psychological characteristics, turns the difficulty into the easiest, turns the boring into the interesting, and receives the ideal result.
