systematics strategy building for solving problems

Creative Problem Solving in School Mathematics, Revised and Expanded 2nd Edition
George Lenchner
I use this book for preparing our math club for the Mathematics Olympiad for Elementary and Middle School Students. It provides systematic practice in problem solving strategies and also plenty of topics in which to use them. If a student is in our club from 4th through 8th grades, they’ll work through most of the book.
