《数学课程标准》指出:“数学教学强调从学生已有的生活经验出发,让学生亲身经历将实际问题抽象成数学模型并进行解释和应用。”这就要求我们在平常的教学中要结合学生的生活经验和已有的知识来设计富有情趣和意义的活动,使学生切实体验到身边有数学,用数学可以解决生活中的实际问题,从而对数学产生亲切感,增强学生对数学知识的应用意识,培养学生的数学能力。
The standard of mathematics curriculum states: “Mathematics teaching emphasizes starting from students’ existing life experiences and let students experience the abstraction of practical problems into mathematical models for interpretation and application. ” This requires us to be in normal teaching Combination of student life experience and existing knowledge to design interesting and meaningful activities, so that students can actually experience the mathematical side, using mathematics to solve practical problems in life, thus creating a sense of intimacy and enhance students’ knowledge of mathematics The application of awareness, develop students’ mathematical ability.
