师:同学们,在四年级的时候,我们已经了解了图形的密铺,请你说一说,什么是图形的密铺?(没有重叠、没有空隙地铺在平面上,就是密铺。)师:图形的密铺又可以叫做镶嵌,以上四个图片,都是由哪些基本图形密铺(镶嵌)而成的呢?(请学生边指边说。)师:还有哪些图形也可以镶嵌?(学生可能回答:三角形,平行四边形,梯形,菱形,正六边形,……)师:今天就请你发挥一下想象力,设计一些与众不同的镶嵌图形。[设计意图说明:学生在四年级已经初步了解了图形的密铺(镶嵌)现象,四幅图片是四年级下册教材《三角形》单元中《密铺》内容中的原图。本单元在此基础上,通过数学游戏拓展镶嵌图形的范围,让学生用图形变换设计镶嵌图案,进一步感受图形变换带来的美感以及在生活中的应用。]二、新授探究一:利用平移变换设计镶嵌图形
