The puzzle consists of a set of pieces and a board with calendar dates. The goal is to use the puzzle as a starter activity in the classrooms and eventually lead the class to explore the symmetry and algebra of polyomino and polyhex pieces. As a part of the STEM program, the puzzle is going to 1000+ schools in India along with 80+ other engaging models/puzzles.en-USConference PaperConference Paper123456789/9047
