“数”与“形”是数学教学最根本的两个方面,数形结合就是把实物、图形和代数有机地结合起来,分析它们之间的对应关系和内在联系,利用数形之间的联系去解决数学问题,从而降低数学问题的难度,找到优化解题的路径,培养学生的学习能力。数形结合思想在数学学习中有着广泛的应用,应贯穿于小学数学教学全过程。一、数形结合,帮助学生建立数感数轴是体现数形结合思想的一个重要工具。数轴将数有规律、有方向地排列,将数与点 “Number ” and “Shape ” are the two most fundamental aspects of mathematics teaching. The combination of number and form is to organically combine the physical objects, graphics and algebra, analyze their correspondence and internal relations, To solve the mathematical problems, thus reducing the difficulty of math problems, find the path to optimize the problem-solving, develop students’ learning ability. The combination of number and shape has a wide range of applications in mathematics learning and should be run through the whole process of elementary mathematics teaching. First, the combination of numbers and shapes to help students build a sense of number of axes is an important tool to reflect the ideas of number-shape combination. The number of axes will be regular, directional arrangement, the number and point
