《数学课程标准(实验稿)》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。”因此,我们认为在小学数学教学中通过操作学具,让学生摆一摆、折一折、剪一剪、量一量、画一画、分一分、拼一拼等,使他们在亲自动手中理解数学概念、促进思维的发展,从而感受数学的童义,发展思维,培养数学能力。 Mathematical Curriculum Standard (Experimental Version) states: “Effective mathematics learning activities can not rely solely on imitation and memory, hands-on practice, self-exploration and cooperation and communication are important ways to learn mathematics.” Therefore, we think that in primary school mathematics Teaching through the operation of learning tools, so that students put a fold, fold, cut, measure a quantity, draw a picture, a minute, spell, so that they understand the concept of mathematics in hands, to promote thinking So as to feel the morality of mathematics, develop thinking and cultivate mathematics ability.
