The Great Shapes Magnetic Activity Board from HearthSong is a virtual 'blank slate,' just waiting for a child to use its palette of 40 brightly colored magnetic shapes to create (and re-create) countless fun designs---then wipe the slate clean and start again. Its convenient carrying case adds a clever blackboard option, and a set of 21 different designs to copy is included for starters! Approx. 10'L x 1.5'W x 10'H; 20.5' when fully open. Wood-framed magnetic board; recommended for ages 3 years and older.
