练习是数学教学的有机组成部分,对于学生掌握基础知识、基本技能和发展动力是必不可少的,是他们学好数学的必要条件。练习是学生将感性知识上升为理性知识的一个实践过程,通过练习,可以使学生加深对基础知识的理解和记忆,可以开发学生的智力,培养学生的各种能力。练习虽然重要,但只有进行正确合理的安排,才 Exercise is an integral part of mathematics teaching. It is essential for students to master basic knowledge, basic skills, and developmental motivation. It is a necessary condition for them to learn mathematics. Exercise is a practical process in which students increase their perceptual knowledge into rational knowledge. Through practice, students can deepen their understanding of basic knowledge and memory, develop their intelligence, and develop their abilities. Exercises are important, but only if they are properly and reasonably arranged
