我家老大五歲，對＂Follow the Money＂比較感興趣。老大三歲對＂If you made a Million＂裏的胖娃很感興趣。
我覺得這兩本書的趣味性和知識性都很不錯，通過通俗易懂的文字、插畫介紹錢幣上的總統、數量、錢的流通。在amazon上查看了custom review，找到其他書，看介紹不錯。有興趣的可以根據link去查。
Here is one review for "How much is a Million":
I'm currently a college student, majoring in Mathematics.
I clearly remember this book, and the sequel by the same author, as huge parts of my childhood love for the subject. Its clear and innovative style helped spark in me a deep love of mathematics. I still imagine big numbers as fields of stars and lines of kids holding fishbowls.
This is perfect for any child, it gives potentially abstract and boring numbers a proper sense of wonder. I can't reccomend it enough.
