数形结合就是把抽象的数学语言、数量关系与直观的几何图形、位置关系结合起来,是最基本的数学思想之一。“数与形本是相倚依,怎能分作两边飞;数缺形时少直观,形少数时难入微;数形结合百般好,隔离分家万事休。”我国著名数学家华罗庚曾这样评价数形结合思想。通过“以形助数”或“以数解形”即利用形的直观加深对数量关系的理解或利用数的抽象性加深对图形的认识,实现了抽象思维与形象思维的结合与转换。在初中数学教材内容中,数轴,绝对值,
Combination of numbers is the abstract mathematical language, the number of relations and intuitive geometry, positional relationship, is one of the most basic mathematical ideas. “Number and shape is dependent on, how can be divided into two sides fly; few lack of shape when less intuitive, shaped when a few are hard to find; shape with a hundred and good all, everything is separated from the rest.” “China’s famous mathematician Hua Luogeng This is the evaluation of digital combination of ideas. Through the ”help form“ ”or “ the number of solution shape ”that is to use the shape of intuition to deepen the understanding of the relationship between the number or the use of the number of abstraction to deepen the understanding of graphics, to achieve a combination of abstract thinking and thinking of the image With conversion. In junior high school mathematics teaching materials, the number of axes, absolute value,
