2、初步认识这一教案内容是在学生已经初步认识长方形、正方形和三角形的基础上进行学习的。教材从引导学生观察实物开始,逐步抽象出角的几何图形,再通过学生实际操作,折一折、比一比、画一画等加深对角的认识和掌握角的基础特征。教材对本单元的要求是初步认识角,知道角各部分的名称,初步学会用尺画角,并初步认识直角,会用三角板判断直角和画直角。学生熟练掌握这部分内容,就为以后继续学习角的有关知识奠定了基础。在本单元中,我分成两个专题来组织学习活动。专题一:角的初步认识:在这个环节使学生初步认识角,知道角的各部分名称,并学会用尺画角;专题二:直角的初步认识:在这个环节使学生初步认识直角,会判断直角并学会画直角。这两
3、个专题的确定是源于教材,且基本覆盖了教材的全部要求,又不拘泥于教材,把知识应用于实际,为今后的学习做了铺垫。主题学习目标(描述该主题学习所要达到的主要目标)2/4 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
4、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 课时)专题二:直角的初步认识(1 课时)专题一角的初步认识所需课时1 课时专题一概述(介绍本专题在整个单元中的作用,以及本专题的主要学习内容、学习活动和学习成果)角的初步认识这一教案内容是在学生已经初步认识长方形、正方形和三角形的基础上进行学习的。教材从引导学生观察实物开始,逐步抽象出角的几何图形,再通过学生实际操作,折一折、比一比、画一
