This set includes 2 puzzles, each containing four animal pieces with knobs; rabbit, dog, bird, cat, elephant, zebra, lion, and giraffe. Puzzles help develop basic skills such as shape recognition, concentration, goal setting, patience and a sense of achievement. They also help develop hand-eye coordination and fine motor skills due to the precise nature of matching each piece exactly. Peg puzzles are easy for small hands to grab on to, allowing for ease in removing the puzzle piece and putting it back where it belongs.
