数字与图形是数学研究的两个基本对象之一,两者可以在一定程度上进行转化,数形结合思想也是数学研究中常用的思想方法,学习的本质即是理解建构过程,通过以形助数、以数化形,使数字之间的关系直观呈现出来,能够帮助还处于形象思维阶段的小学生在学习中理清数学关系,更好地解决数学问题。教师如何在数学课堂更好地运用数形结合思想?本文从运用数形结合思想,有效打好数学基础;运用数形结合思想,有效突破数学难点;运用数形结合思想,有效拓展数学能力三个方面阐述。
Digital and graphics are two basic objects of mathematical research. They can be transformed to a certain extent. The idea of digital combination is also a common method of thinking in mathematical research. The essence of learning is to understand the process of construction. Number, with a number of figures, so that the relationship between the number of visual presentation, can help still in the image of the thinking stage of primary school students to clarify the mathematical relationship between learning, to better solve mathematical problems. How can teachers make better use of the idea of number combining in math class? In this paper, we apply the idea of number combining to effectively lay the foundation of mathematics; use the combination of number and shape to break through mathematics difficulty effectively; A
