1、圆的认识教学设计城关二小杨菊莲教学内容:教材第页的内容及练习。教学目标:1、使学生认识圆,掌握圆的特征;了解圆的各部分名称。2、会用字母表示圆心、半径、直径;理解并掌握在同圆(或等圆)中直径与半径的关系。3、能正确熟练地掌握用圆规画圆的操作步骤。4、培养学生动手操作、主动探究、自主发现、交流合作的能力。教学重难点:了解圆各部分的名称,理解并掌握圆的特征探究圆内的直径与半径的关系。教学方法:自主探究,合作交流教学准备:多媒体课件学生准备圆形物体和圆形纸片教学过程:一、导入新课(1)师生对话教师:日常生活中或周围的物体上哪里有圆?学生:在钟面、圆桌、人民币硬币上,都有圆。教师:请同学们用手摸一摸,

2、体会一下有什么感觉?学生用眼看一看、用手摸一摸,感觉:,闭封的、弯曲的。教师(多媒体演示:圆形物体圆):这(指圆)和我们以前学过的平面图形,有什么不同呢?学生:以前我们学过的平面图形如长方形、正方形、三角形、平行四边形和梯形的共同特征,都是由线段围成的直线图形。而我们现在看到的(指圆)这种图形是由曲线围成的图形。教师(鼓励表扬学生):对,这个图形就是圆,你能说说什么是圆吗?学生讨论后回答:圆是平面上的一种曲线图形。(这时,教师请同学们把眼睛闭上,在脑子里想圆的形状,睁开眼睛再看一看,再闭上眼睛想一想,能否记住它。)教师在此基础上揭示课题,并请学生回答:你还想认识圆的什么?学生说:还想认识圆的圆

3、心、直径、半径,这里通过生生交流、师生互动,形象感知、抽象概括,帮助学生正确建立“圆”的概念。二、探索新知。(2)探究圆的直径、半径及其关系。教师:你还想知道什么?学生:还想知道圆的直径、半径,直径与半径之间有什么关系?,分组探究,合作学习。教师提出学习活动要求:(课件出示要求,让学生一步步完成,在汇报交流)通过动手“折、量、画、数、比(估)、看、议”等方法。操作检验,内化提升。a.考考你的判断力。(课件出示判断圆内的哪些线段是半径或直径)动手量一量自己圆中的半径和直径,你发现了什么?学生汇报交流,教师演示。或板书b.对答游戏(每两个学生一组):你说直径长度,我答半径长度;你说半径长度,我答直

27、玩”中学习。如“游戏趣味题”中“教师的评说”,能唤起学生学习的热情。如“自我习作、操作表演、大家共赏”,享受成功的愉悦,可激发学生探知的欲望。如让学生剪、折、画、量、议、找,多种感官参与活动,可培养学生的动手、实践能力,学会探索的方法。如通过学生评价教师、学生,师生平等相待,可解放学生的脑、手、眼,让学生大胆地想、放开去说、随心地做,有利于培养学生的创新精神和探究能力。教学中师生互动、生生互动、民主平等、开放自由、心心相映、情感交融,课堂充满了生命活力,这样教学有力地促进了学生学习方式的改变。置身于这样的学习情境之中,真正达到了“让学生享受学习”的意境。文档编码:CJ1I7T9S5A1 HH5
