2、你们都买过什么？同学们买过的东西还真不少，谁能把自己购物秘诀跟大家分享一下呢？找学生回答。这些都是同学们的宝贵经历，这样看来，买东西的学问还真不少呢！这节课我们就一起来讨论讨论买东西看什么。活动一：观察包装袋认识“三无”产品今天老师把懒羊羊和他的小伙伴喜羊羊一起请到了我们的课堂一起学习，大家知道懒羊羊有个大毛病，那就是贪吃，一不小心吃着吃着就吃出问题来了，瞧(出示课件)。喜羊羊：懒羊羊你又偷懒又不去上体育课。懒羊羊：我在路边摊买了包零食吃，吃了以后肚子疼喜羊羊：什么！你在路边摊买的？吃了不肚子疼才怪呢，你是不是买了“三无”产品了。懒羊羊：“三无”产品？什么是“三无”产品呀。同学们你们知道什么是
