著名数学家华罗庚说过“数缺形时少直观、形少数时难入微”。形象地反映了数与形之间的关系,同时也是对数学教学工作提出的要求。《数学课程标准》中指出:“要重视直观,处理好直观与抽象的关系。”小学阶段学生的思维仍处于相当长的直观阶段,数形结合对培养学生的思维能力,提高分析问题、解决问题的能力,以及获得基本的数学思想具有很重要的作用。一、数形结合,加强对数的认识认数是小学阶段数学学习的重要内
Well-known mathematician Hua Luogeng said “few lack of shape less intuitive, shaped when the minority is hard to micro ”. Image reflects the relationship between number and shape, but also the requirements of mathematics teaching. “Mathematical Curriculum Standards” pointed out: “We should pay attention to the visual and handle the relationship between intuition and abstraction.” "The thinking of primary school students is still at a fairly long and intuitive stage. The combination of numbers and forms can improve students’ ability of thinking and analysis , The ability to solve problems, and access to basic mathematical ideas have a very important role. First, the combination of a few figures, to enhance understanding of the number of recognition of primary school mathematics learning is important
