如果在教完1+1=2后,你还会问孩子“1+1还能等于几”吗?也许你会认为这是一个违反常识的怪问题,而赴德国参观考察的中国老师就亲眼目睹了这样的事实: 在一节数学课上,一位德国老师用几个苹果几块糖做教具教1+1=2。他讲完1+1=2后,竟轻声地问孩子:“请小朋友们仔细再想想,1+1还能等于几呢?”这一问,孩子 If after teaching 1 + 1 = 2, will you still ask your child if “1 + 1 can be equal to”? Perhaps you may think this is a strange problem that violates common sense, and the Chinese teacher who visited Germany Witnessed the fact that in a math class, a German teacher made a number of apples with a few apple pieces to teach 1 + 1 = 2. After he finished 1 + 1 = 2, he whispered to ask the child: “Please children carefully think about it, 1 + 1 can also be equal to a few?” This question, the child
