“数”和“形”是小学数学教学的研究对象,也是贯穿小学数学教材的两条主线。所谓的“数形结合”就是根据数量与图形之间的对应关系,把抽象的数学语言与直观的图形相结合,使抽象思维和形象思维相结合,通过数与形的相互转化来解决数学问题的一种重要的数学思想,也是一种常用的数学方法。而数学思想方法就是增强学生数学观念,形成良好思维素质的关键。所以,在小学数学的教学中,教师要有意识地沟通数、形之间的联系,帮助学生逐步树立起数形相结合的观点,提 “Number ” and “Form ” is the subject of primary school mathematics teaching, but also through the two main lines of primary school mathematics textbooks. The so-called “combination of numbers ” is based on the correspondence between the number and graphics, the abstract mathematical language and intuitive graphics, the combination of abstract thinking and thinking, through the conversion of numbers and shapes to solve Mathematics is an important mathematical problem, but also a common mathematical method. The mathematical method is to enhance students’ mathematical concepts, the key to a good thinking quality. Therefore, in the teaching of primary mathematics, teachers should consciously communicate the connection between the number and form, to help students gradually establish the combination of several forms of point of view, mention
