《全日制义务教育数学课程标准(实验稿)》明确指出:小学数学教学目标不仅仅要使学生掌握基础知识及技能,而且要让学生在日常的数学活动中“经历、感受、体验、探索”,让学生在探究学习中实现过程性目标,在探究过程中获得充分发展。本文试以“千克的认识”教学片断为例,谈谈如何让学生在体验中“做”数学。 Full-time compulsory education mathematics curriculum standards (experimental draft) “clearly states: primary mathematics teaching objectives not only to enable students to master the basic knowledge and skills, but also to allow students in the daily math activities” experience, feel, experience, explore “ , To enable students to achieve procedural goals in inquiry learning and achieve full development in the process of inquiry. This article attempts to ”kilogram of knowledge“ as an example of teaching, to talk about how to make students ”experience" in the experience of mathematics.
