知识与技能：1初步认识角和直角，知道角各部分名称。2初步认识到角的大小与两边张开的大小有关。过程与方法：1培养学生初步的空间观念和抽象思维能力。2培养学生的动手，语言表达，合作交流等能力。情感态度与价值观：1通过学习激发学生探索知识的欲望，培养学生自主学习的精神，促学生知、情、意、行同步发展。2通过分组讨论，实践操作等活动，增强学生合作交流的意识,培养学生善于思考的学习习惯。3渗透数学知识来源于生活，应用于生活的观念。对应课标对应标准：教案生初步认识角，知道角各部分的名称，会画角，使学生初步认识直角，会用三角板判断直角和画直角，并体会角和直角存在于生活中，感受数学与生活的密切联系。主题单元问题设计角有哪几部分组成的？怎样画角？直角有什么特点？怎样画直角？专题划分专题一：角的初步认识（1
