These first puzzles grow with your child. As preschoolers master the 3 piece puzzle, they then progress to the 4 piece, 5 piece and 6 piece puzzles. With four puzzles included in each set your budding puzzler will soon be constructing an excavator, a bulldozer, a concrete mixer and even a loader!  Made from recycled cardboard and printed with vegetable inks.
