数学的一个重要特点,是它具有抽象性。而小学低年级学生的思维,正处于以形象思维为主的阶段。要使他们理解地“消化”抽象的数学知识,仅凭教师“架空”的语言阐述,是不能达到教学要求的。因此,小学低年级的数学教学,要下功夫加强操作指导,促使智能的“内化”。设计操作的程序操作作为帮助学生理解新知,锻炼思维的一种手段,需要教师精心设计合理的操作程序。如“元、
An important characteristic of mathematics is that it is abstract. The thinking of the students in the lower primary school is in the stage of thinking based on the image. To make them understand “to digest” abstract mathematical knowledge, it is impossible to meet the teaching requirements merely by the language of the teacher “overhead”. Therefore, the mathematics teaching in the lower grades of primary schools should make efforts to strengthen the operation guidance and promote the “internalization” of intelligence. The operation of the design process as a means to help students understand the new knowledge, exercise thinking, requires teachers to carefully design a reasonable operating procedures. Such as "yuan,
