要学好数学,练习是必不可少的,只有完成一定数量的数学练习题,才能巩固所学知识,正确理解概念、定理、公式等,逐步形成技能、技巧,不断提高观察、比较等思维能力。因此,数学教师必须充分挖掘教材资源,精心组织练习,变有限为无限,从而促进学生的思维发展。 To learn math, practice is essential. Only by completing a certain number of math exercises can we consolidate what we have learned and correctly understand the concepts, theorems and formulas, and gradually form skills and techniques to constantly improve our thinking skills such as observation and comparison. Therefore, mathematics teachers must fully tap the resources of teaching materials, carefully organize exercises, change limited to unlimited, so as to promote the development of students’ thinking.
