As part of their interim assessment in Labor Training, fourth-grade students faced a challenging yet exciting task: designing and building their own tabletop puzzle game—a "Labyrinth." The project combined elements of construction, logic, and artistic design. The students followed the full process of a professional game developer, moving through planning, prototyping, and decorating. Each project turned out interesting and unique. At the end of the lesson, the fourth-graders tested their classmates' labyrinths and appreciated the effort that went into creating them.
