Chi once played a coin game with some aboriginal first-graders. She wanted students to combine coins so that the total equaled NT $ 25. Some students were very clear that coins had different values of NT $ 1, NT $ 5 and NT $ 10 and quickly made correct combinations. But most of them didn't care about the face values of the coins, and merely counted 25 coins of different values.
紀惠英曾跟一年級的小孩「玩」計算幣值的遊戲，她要學童拿出二十五元來，有的孩子會很清楚地辨認幣值不同的一元、五元、十元等，找出共二十五元；但大多的小孩則不管幣值大小，一律以數量做總數，常找出不同幣值的二十五個硬幣來。
