After they learn what the various fruits look and smell like and how much they cost, they get practical experience in addition and subtraction when they purchase their favorite fruits with the NT $ 50 that she issues to each group of tykes. Back at school, they use the fruit to create pieces of mosaic art.
她發給每一組孩子 50 元，讓孩子認識水果的模樣、氣味、價錢後，實際加減計算，買回小組最愛的水果，回到學校再拿這些水果做為創作材料，合力拼出美術作品來。
