Farm Life Series II, 3-in-1 puzzles include three different farm scenes and different piece counts.  The puzzle piece sizes will be different, so it is obvious which pieces belong together.  The six piece is a good starter puzzle as each piece has a flat edge.  As the puzzle progresses in piece count, children learn how to connect not just edge or border pieces, but the inner, less obvious pieces as well.  Fun farm scenes will keep the kids entertained even after the puzzle is completed! Each puzzle measures 6.375" x 6.375" when complete.
