In 1988, successful inventor ROBERT SUN embarked on a journey to teach children the relationship between numbers through a game. The result of his efforts was the 24® game, a unique mathematics teaching tool that has proven to successfully engage students in grades 1 through 9 from diverse economic and social backgrounds. "Knowing the answer is always 24 alleviates a classic brand of math anxiety—getting the right answer—and instead puts the emphasis on the process and patterns, what I like to call the method behind the math,” says Sun.
