14、一阶段的学习后，学生在教师的引领下，自主、合作梳理单元知识与技能、构建数学思维网络。这节课不是简单地知识与回顾，而是学生们自主梳理，展示自我的舞台，学生在相互交流、分享、展示和评价的过程中，将一单元的知识形成整体的网络系统，发现、提出、分析、解决问题能力得到进一步的提高。二、单元梳理课的意义1、单元知识梳理能够加深学生对知识的理解。2、单元知识梳理可以使知识系统化。三、单元梳理课的原则1、关注梳理方法。2、鼓励学生自主、合作梳理知识。3、注重学生数学水平的提高。四、单元梳理课的特点1、再现性。2、概括性。3、系统性4、综合性五、单元梳理课的教学流程1.课前自主梳理。这部分内容教师课前要根据班级学生的实际情况和本单元的重、难点，精心设计课前尝试小研究作业，内容包括知识点的梳理以及典型题和易错题的梳理。学生梳理的形式不限，可以是文字式、表格式、画图式等，总之放手让学生采取个人喜欢的方式进行梳理，调动学生的积极性和主动性。2 .组内交流完善梳理。在交流的过程中，吸取他人的长处，比如知识点整理的疏漏，解题技巧的妙招，透过生生的思维碰撞，完善个人的知识梳理，解决小组中同学之间存在的问题。3 .班级交流提升梳理。各小组汇报小组中的知识梳理，提出本单元应该注意的问题以及典型题和易错题等，形式可以是展示，提问和质疑等多种形式。这一环节有助于学生进一步领略单元知识的全
