Puzzle Doubles giant products take the concept of a traditional puzzle to a whole new level. Each giant floor puzzle in this series includes a 30-piece, 2"x3", beautifully illustrated "talk about" floor puzzle. After assembling the puzzle, turn it over for a giant coloring activity. Use the four write-on/wipe-off crayons that are enclosed to color each large scene. You can wipe off the crayons with a dry cloth. Puzzle doubles provide the children with multiple learning activities all combined in one great product.
