第三单元 绿色小卫士11 我是一张纸,找一找,我在哪,请同学们仔细观察图片并找出神秘朋友。,1.学习用纸:课本、画画本、作业本、课外书这些都是我们学习中常用的东西,可见我们的学习离不开纸。,2.生活用纸:餐巾纸、纸杯、报纸、箱子、挂历、纸币这些都是我们生活中常用的东西,可见我们的生活离不开纸。,3.美化纸:窗花、灯笼、壁纸、纸折的各种装饰品这些用纸做的东西使我们的生活变得更加有情趣,可见纸可以美化我们的生活环境。,了解纸的来历,体会纸的来之不易,造纸的过程,制造纸张需要经过漂白、压膜、烘干等许多工序,一张小小的纸来之不易。,交流浪费纸的现象,树立节约用纸的意识,(1)你们知道图中的几个孩子在干什么吗?你们认为他们的做法对吗? (2)咱们班有没有这样的现象?我们以后应该怎么做呢?,(1)你们看到了什么? (2)和纸做朋友,我们还可以怎么做?不可以怎么做呢?,课堂小结,通过本节课的学习,我们知道了一张小小的纸要经过好多工序才能制造出来,它来之不易,我们一定要节约用纸。,板书设计,谢谢,
