数学是抽象性、逻辑性很强的一门学科。小学生的思维正处于由具体形象思维为主向抽象逻辑思维为主的过渡阶段。尤其对于低年级的小学生而言,在学习中,他们更多地关注“有趣、好玩、新奇”的事物,动作思维与形象思维是支撑他们学习的主要形式。《数学课程标准》也指出:“有效的数学学习活动不能单纯地依赖模仿与记忆,动手实践、自主探索与合作交流是学习数学的重要方式。”由此可见,在低年级数学课教学中,适当地引导学生动手操作,让学生通过学具操作参与知识的形成过程, Mathematics is an abstract, highly logical discipline. The thinking of primary school students is in the transition stage from the concrete image thinking to the abstract logical thinking. Especially for the elementary students in the lower grades, they pay more attention to things like “fun, playfulness and novelty” in their study. The action thinking and the image thinking are the main forms that support their learning. The standard of mathematics curriculum also states: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, independent exploration and cooperation and communication are important ways to learn mathematics.” Thus, in the lower mathematics teaching In appropriate guidance to students hands-on operation, so that students through the operation of learning tools involved in the formation of knowledge,
