This article features Sweet play math, a "math by the month" activity that involves decorating and making sugar cubes. Teachers may want to substitute straws, paper squares, alphabet blocks, or such commercially made manipulatives as Unifix[R] cubes for the real sweets. Given no allergy concerns, teachers and students alike would enjoy some sweet rewards after having a taste of these mathematical explorations. Full-sized students' activity sheets of sweet play for grades K-2, 3-4, and 5-6 are presented.
