小明的爷爷是个“旅游迷”,他从美国买回来一个光盘,光盘的内容是《美国数学趣题集》.这些趣题大多与生活、生产的实际相关,对培养学生应用数学解决实际问题的能力和培养思维能力很有帮助.这次数学兴趣小组的活动别开生面,是因为小明把光盘带来的缘故.同学们边看电视屏幕上的趣 Xiaoming’s grandfather is a “traveling fan”. He bought a CD from the United States. The content of the CD is “America’s Math Interests Collection.” Most of these interesting questions are related to the actual life and production, and they are used to train students in applying mathematics to solve practical problems. Ability and ability to develop thinking skills are very helpful. The activities of this number of interest groups are unique because Xiaoming brings CDs. Students watch TV screens
