Comment ... the Facts aren't what's -really- important (Score 1) 489
Especially if you are looking to -suppliment- an education system that is based on "here is a TYPE X problem ... you solve it this way with this algorithm ..."
I suggest books such as Proofs from THE BOOK. Firstly it deals with topics outside the -regular curriculum- but whose problems are easily explained to (and understood by) just about anyone. "Graph Theory" ... simply put "connect-the-dots". "Combinatorics", well that's just "counting things".
This book is particularly good as it offers, in many cases, more than one proof for a given problem, looking at problems in different creative ways to find elegant solutions. Feynman was a huge advocate of this (see the "Cargo Cult Science" chapter in his book Surely you're joking Mr. Feynman!
