2022年一上《认识立体图形》教学设计精品教育 .pdf

学习好资料欢迎下载一上：认识立体图形教学设计一、教学目标（一）知识与技能在分类、观察、动手操作等活动中，直观认识长方体、正方体、圆柱、和球，并能辨认和区别这些图形。（二）过程与方法在对图形进行分类的活动中渗透分类的思想。（三）情感态度和价值观培养学生初步的观察、想象、表象思维和语言表达的能力，初步建立空间观念，初步感受数学与实际生活的联系。二、目标分析这部分内容是学生学习图形与几何的开始，学生虽然没有经历系统学习图形知识，但是学生从小就玩积木，在玩的过程中积累了大量的生活经验。因此本课就从玩积木开始切入，使学生在玩的过程中了解、感知这几种图形的特征。三、教学重难点教学重点：使学生能够初步认识长方体、正方体、圆柱、球，能够正确识别这几种图形。教学难点：正确区分长方体和正方体。四、教学准备形状为长方体、正方体、圆柱、球的积木和实物。五、教学过程学习好资料欢迎下载（一）激趣引入导语：今天开始学习图形。（出示课件）我们和小熊一起来认识图形吧。这些图形很有趣，就像我们小朋友一样，有的很乖，有的很淘气。【设计意图】通过采用富有童趣的提问方式，给学生创设愉悦的学习氛围，激发学习兴趣。引导学生观察物体，意识到些物体是有区别的，为了解图形的特征做准备。（二）初步认识图形的本质特征1认识球。（1）找一找：哪种图形最淘气?为什么认为它最淘气？（2）摸一摸：找出学具中的球摸一摸，发现球的特征：圆乎乎的，可以任意滚动。（3）贴图：把球画在纸上，就是这样的。2认识圆柱。（1）找一找：哪种图形比较淘气，会顺着一个方形滚动，但不会随意滚动。（2）摸一摸，试一试：在做操作中感受发现圆柱的特征：除了有两个平平的面，侧面是弯的，上下一样粗，可以来回滚动，但不能随意滚动。（3）贴图：像这样有两个平平的面，一个弯弯的面，并且上、下一样粗的图形叫圆柱。（4）出示短粗形圆柱：这个图形是圆柱吗？说一说理由吧。文档编码:CR10K6T1M2G7

个面不是一样大的。（3）辨别扁的长方体。教师拿出扁长方体，把正方形的一面对准学生，让学生辨别这是什么图形，引发学生思维冲突，引导学生辩论出它为什么是长方体。小结：我们通过，看一看、摸一摸、试一试的方法，认识了球、圆柱、长方体、正方体这四种图形。【设计意图】在具体事物的辨析中，初步建立图形的特征，为后续进一步认识图形奠定基础。（三）再次分类认识图形特征1为图形分类让学生将桌上的所有图形分类。此时，学生很容易运用刚刚掌握的知识将这些图形分成4 类。2找朋友游戏：文档编码:CR10K6T1M2G7 HR6H6Q7R5V3 ZM3K6F7O4B8文档编码:CR10K6T1M2G7 HR6H6Q7R5V3 ZM3K6F7O4B8文档编码:CR10K6T1M2G7 HR6H6Q7R5V3 ZM3K6F7O4B8文档编码:CR10K6T1M2G7 HR6H6Q7R5V3 ZM3K6F7O4B8文档编码:CR10K6T1M2G7
