My first puzzle set series are great “starter” puzzles and will help little hands develop their fine motor skills. 4 In a box abc introduces first letters and sounds to your little one. The puzzles progress from 2 pieces to 4 pieces to 6 pieces to 8 pieces, giving your child the opportunity to grow with the set as they grow and develop. The 8 piece puzzle brings the characters from the other three puzzles together in one animated scene with lots to discuss and talk about. My first puzzle sets are a great way to help your toddler begin building their tactile and problem solving skills. Each puzzle measures approximately 12.5” X 8.5”. Ages 2+ years.
