小学数学教学中有效渗透数形结合思想的体会

The Experience of Effectively Penetrating the Combination of Numbers and Shapes in the Teaching of Mathematics in Primary Schools

把数量关系和空间形式结合起来去分析问题、解决问题,就是数形结合思想。数形结合不仅是一种重要的数学思想,也是一种很好的教学方法。著名数学家华罗庚先生曾经说过:“数缺形时少直观,形少数时难入微”。在教学中,许多算理学生模棱两可,如能做到数形结合,学生便可透彻地加以理解。下面我就结合自己的教学实际谈谈在教学中如何有效渗透数形结合的数学思想。

Combining quantitative relations with spatial forms to analyze and solve problems is the combination of numbers and shapes.The combination of numbers and shapes is not only an important mathematical thought,but also a good teaching method.Hua Luogeng,a famous mathematician,once said,"number is less than form and time is less intuitive."In teaching,many arithmetic students are ambiguous.If they can combine numbers with shapes,they can understand them thoroughly.Next I will combine my own teaching practice to talk about how to effectively infiltrate the mathematical thinking of the combination of numbers and shapes in teaching.
