Originally published in France, this translation of mathematical conundrums offers Englishspeaking students, as well as lovers of math games and logic puzzles, an opportunity to meet the challenges devised by the F\'ed\'eration Fran\c c{}aise des Jeux Math\'ematiques for the International Championship of Mathematics. Designed to address a students' reasoning skills rather than knowledge, this series of 50problem sets represents the best of more than a decade's worth of championship questions. The three collections are organized by mathematical themes  geometry and symmetry, arithmetic and number theory, logic and algorithmic process  to easily adapt to an instructor's curriculum. Each book is arranged with one problem per page for easy overhead use or distribution. The Orange Collection is the intermediate set, designed for high school students (grades 9 to 12). Concepts include the division of polygons into tilings of congruent shapes; knots, chains, and networks; deciphering messages and breaking codes. A few solutions are facilitated with algebra and trigonometry.
