An Engaging Series of Problems More than a decade's worth of puzzles and problems from the International Championship of Mathematics are found in this three-volume set. The problems are organized by mathematical themes-geometry and symmetry, arithmetic and number theory, logic and algorithmic process-for easy adaptation to your mathematics curriculum. Orange Collection The Orange Collection (Grades 9-12) 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.
