Abstract: A kit for making a floor on the permanent floor of a venue from modules. Adjacent modules are releasably interconnected by magnetic coupling means. A flooring module base layer having an upper surface with upwardly facing grooves that include magnetic coupling means for connecting it to a complementary magnetic coupling means on an adjacent activity layer. A flooring module activity layer having a lower surface with downwardly facing grooves that include magnetic coupling means for connecting it to a complementary magnetic coupling means on an adjacent base layer. A method for making a floor from a plurality of modules that are placed in contact with each other so that a portion of each module overlies an upwardly facing or downwardly facing portion of each adjacent module. The adjacent modules are coupled to each other by the magnetic coupling means to create a floor of desired area.
