新课程理念实施以来,不难发现实践活动课已成为课程改革中一道靓丽的风景线。《义务教育数学课程标准》(实验稿)明确提出:“让学生通过实践活动,初步获得一些数学活动的经验,了解数学与生活的广泛联系,加深对所学知识的理解,获得应用数学解决问题的思考方法,并能与他人合作交流,获得积极的数学学习情感。”数学实践活动,因具有操作性、主体性、开放性、挑战性、互动性、灵活性、新颖性等特点,学生感到生动有趣,学得轻松自 Since the implementation of the new curriculum concept, it is not difficult to find that the practice activity class has become a beautiful landscape in the curriculum reform. The compulsory education mathematics curriculum standard (experimental draft) clearly states: “Let students get some experience in math activities through practical activities, understand the extensive connection between math and life, deepen the understanding of the learned knowledge, and get applied mathematics solution Problem-solving methods, and can cooperate with others to exchange and obtain positive math learning emotion. ”Mathematics practice activities, because of operational, subjectivity, open, challenging, interactive, flexible, novelty and other characteristics, Students feel lively and enjoy themselves
