课堂练习作为课堂教学的重要环节,是教学信息反馈的重要渠道,是学生由知识到技能形成的桥梁。几何形体知识具有一定的抽象性,小学生理解和掌握起来比较困难,因此必须设计形式丰富的练习进行及时的巩固和消化,提升学生对几何形体知识的理解、掌握与应用,并在练习中提升学生数学思维的能力。一、操作性练习,培养空间观念《义务教育数学课程标准(2011)》指出:几何知
Classroom practice as an important part of classroom teaching is an important channel for teaching information feedback and a bridge between knowledge and skills. Geometry knowledge has a certain degree of abstraction. It is difficult for pupils to understand and master it. Therefore, it is necessary to design and practice rich forms of practice to timely consolidate and digest students ’understanding, mastery and application of geometry knowledge and enhance students’ Mathematical thinking ability. First, operational practice, training space concept “compulsory education mathematics curriculum standards (2011)” pointed out: Geometry know
