This 26-piece wooden puzzle pronounces the correct name of each letter when it is placed correctly in the puzzle board! Pieces are slightly raised above the puzzle board for easy grasping. Colorful pictures underneath each piece help reinforce the relationship between letters and their sounds. (TIP: Puzzle has light-activated sensors; for best results, expose a sensor by removing pieces in a brightly lit room, then make the sound play by replacing the piece in the board.)
