数学是研究数量关系、空间图形、数的变化、数的规律等以及它们之间关系的一门学科。数形结合是一种非常重要的思想,把数与形有机地结合起来解决问题,可使复杂的问题变得简单,使抽象的问题变得直观。数与形相结合的例子在小学数学教材与教学实践中随处可见。比如说,有的题型是图形中暗含着数的规律。那么,如何让学生轻而易举地从中找出数的规律来呢?首先让学生通过分析图形,然
Mathematics is to study the relationship between quantity, space graphics, number changes, the law of numbers and the relationship between them. The combination of number and shape is a very important idea. The combination of number and shape solves the problem, which can make the complex problem simple and make the abstract problem intuitive. The combination of numbers and forms can be seen everywhere in elementary mathematics textbooks and teaching practice. For example, some questions are implied by the number of laws in the figure. So, how to make it easy for students to find out the law of numbers come first? Let the students through the analysis of graphics, of course
