The benefits of puzzles are well documented. Putting together a puzzle develops cognitive, eye-hand coordination, fine motor, and spatial skills. The process of figuring out how the pieces go together involves problem solving, persistence, and patience and builds self esteem. Working cooperatively on a puzzle develops social skills. Ship, a 4-piece puzzle in a 6″ square wooden tray, is one in a collection of three traditional wooden block puzzles. The others, sold separately, are Car and Ladybug.
