This 21-piece wooden sound puzzle pronounces the name of each number when its piece is placed correctly! Pieces are slightly raised above the puzzle board for easy grasping. Colorful pictures underneath each piece help teach counting and reinforce the relationship between quantities and numerals. This educational puzzle has lots of ways to learn and play! (TIP: Puzzle has light-activated sensors; for best results, expose the sensor by removing a piece in a brightly lit room, then make the sound play by replacing the piece in the board.) 2 AAA batteries required, not included.
