众所周知,小学生的逻辑思维能力比较弱,特别是第一学段的学生更依赖于直观形象思维,而数学学科又具有较强的抽象性和逻辑性。因此,教学过程中,教师要想方设法用学生易于理解的方式呈现抽象的数学问题,比如,借助数形结合思想中的图形直观手段,就是一种非常好的教学方法和解决方案。著名数学家华罗庚说过:“数缺形时少直观、形少数时难入微”。数形结合思想就是通过数和形之间的 As we all know, primary logic ability of students is relatively weak, especially in the first semester students rely more on intuitive thinking, and mathematics has a strong abstract and logical. Therefore, in the process of teaching, teachers should find ways to present abstract mathematical problems in a way that students can easily understand. For example, using the combination of figure-shaped and graphic visual methods in thought is a very good teaching method and solution. Hua Luogeng famous mathematician said: “When the number of lack of shape less intuitive, shaped into a minority few micro ”. The idea of ​​associating numbers with numbers is by number and shape
