一、编排特点1.提供丰富的素材,加强数学与生活的联系,利用学生的已有经验展开教学活动教材选取了学生日常生活中熟悉的形形色色的包装盒作为素材,使学生感受到数学就在身边。同时借助素材,引导学生通过观察、比较、操作,从直观到抽象学习知识,有利于学生构建新知识。长方体和正方体是日常生活中较为常见的形体,也是最基本的立体图形。学生在低年级对这两种图
First, the layout features 1 to provide a wealth of material, to strengthen the connection between mathematics and life, the use of existing teaching experience of students to start teaching activities selected textbooks in the daily life of students familiar with all kinds of packaging as a material, so that students feel that mathematics is Around. At the same time with the material, to guide students through observation, comparison, operation, learning from intuitive to abstract knowledge is conducive to students to build new knowledge. Cuboids and cubes are more common in everyday life, but also the most basic three-dimensional graphics. Students in the lower grades of these two plans
