More than a decade's worth of puzzles and problems from the
International Championship of Mathematics organized by the Fédération
Française des Jeux Mathématiques have recently
been translated into English and published in this three-volume
set.

These problems from the championship are organized by mathematical
themes—geometry and symmetry, arithmetic and number theory,
logic and algorithmic process—for easy adaptation to
your mathematics curriculum.
Created for all puzzle and game lovers and students, this
engaging series of problems relies more on reasoning than knowledge.
It will give your students hours of investigative problem solving
and will reinforce and integrate the fundamental themes of
traditional mathematics with discrete mathematics.
Each book of 50 problems is laid out with one problem per
page for easy overhead use or distribution. Full solutions
are provided.
The Green Collection (Grades
6–12) -- Discontinued
The Orange Collection (Grades
9–12) [4 Left in Stock] is
the intermediate set and will challenge most high school students.
Students divide polygons into tilings of congruent shapes;
they encounter knots, chains, and networks; they decipher messages
and break codes. A few solutions are facilitated with algebra
and trigonometry. 96

The Red Collection (Grades 9–College) [3 Left in Stock] is
the most challenging set, involving distance, vectors, transformations,
systems of equations, series, powers, and number theory. Problems
are solved with compass and straightedge constructions, trigonometry,
the Pythagorean theorem, synthetic division, and a great deal
of ingenuity. 96
