22、动体现的内容是“由平面图形经过旋转形成几何体”,这不仅是对几何体形成过程的学习,同时体会面和体的关系也是发展空间观念的重要途径,这也是教材将此课题目定为“面的旋转”的原因.教材呈现了几个生活中的具体情境,鼓励学生进行观察,激活学生的生活经验,使学生经历“点动成线”“线动成面”“面动成体”的过程.在结合具体情境感受的基础上,教材又设计了一个操作活动,通过北师大版小学六年级数学下册全册教案(word 版可编辑修改)manipulator control mode and programmable controllers introduction 2.1 Select discussion with

32、操作与思考、想象相结合,发展学生的空间观念操作与思考、想象相结合是学生认识图形、探索图形特征、发展空间观念的重要途径。在本单元中,教材重视学生操作活动的安排,在每个主题活动中都安排了操作活动,促进学生理解数学知识、发展空间观念。如“圆柱的表面积”的教学中,教材引导学生通过操作来说明圆柱的侧面展开后是一个怎样的图形,并呈现了两种操作的方法:一种是把圆柱形纸盒剪开,侧面展开后是一个长方形;另一种是用一张长方形纸卷成圆柱形。再如本单元的最后专门安排了一个“用长方形纸卷圆柱形”的实践活动,先让学生用两张完全一样的长方形纸,一张横着卷成一个圆柱形,另一张竖着卷成一个圆柱形,研究两个圆柱体积的大小;然后组
33、织学生将两张完全一样的长方形纸裁开,把变化形状后的纸再卷成圆柱形,研究圆柱体积的变化,引导学生发现规律,深化对圆柱表面积、体积的认识,并体会变量之间的关系.3。引导学生经历圆柱和圆锥体积计算方法的探索过程,体会类比等数学思想方法类比是一种重要的数学思想方法,是合情推理时常用的方法。教材重视类比、转化等数学思想方法的渗透。在“圆柱的体积”教学时,教材引导学生经历“类比猜想-验证说明的探索过程.由于圆柱和长方体、正方体都是直柱体,而且长方体与正方体的体积都等于“底面积高”,由此可以产生猜想:圆柱的体积计算方法也可能是“底面积高。在形成猜想后,教材再引导学生“验证说明”自己的猜想。在“圆锥的体积”教
34、学时,教材继续渗透类比的思想,再次引导学生经历“类比猜想验证说明”的探索过程。另外,教材还注意转化、化曲为直等思想方法的渗透,如在验证说明“圆柱的体积底面积高”时,引导学生把圆柱切割拼成近似的长方体进行研究,体现了化曲为直的思想方法.4.在解决实际问题中巩固所学知识,感受数学与生活的联系圆柱和圆锥的知识在生活中有着较为广泛的应用,教材在编排练习时,选择了来自于现实生活的问题,引导学生灵活运用所北师大版小学六年级数学下册全册教案(word 版可编辑修改)manipulator control mode and programmable controllers introduction 2.1 S
