摘要
在数学教学中，如果能注意把数和形结合起来考察，根据问题的具体情形，把图形性质的问题转化为数量关系的问题，或者把数量关系的问题转化为图形性质的问题，使复杂问题简单化，抽象问题具体化，化难为易，就可获得简便易行的成功方案，因此，必须重视数形结合的教学。
In mathematics teaching, if can pay attention the number and the shape unifies the inspection, according to the question concrete situation, transforms the graph nature question as the stoichiometric relation question, or transforms the stoichiometric relation question as the graph nature question, causes the complex question simplification, the abstract question concrete application, melts thanks easily, may obtain the successful plan, therefore, must take the number shape union the teaching.
