Single Shape Montessori Peg Puzzle Gift Set by Maria and Me--Great for Developing Fine-Motor Skills and Concentration JUST THE RIGHT CHALLENGE unlike other shape puzzles, you can isolate a single shape to start with this puzzle, offering the perfect challenge for an older baby. As your child gains confidence, introduce more challenging shapes, and then combine to add another layer of challenge; because of this single-shape design, this set can be used earlier and longer than other similar puzzles! TEACH SHAPES AND CONCEPT OF SCALE three simple geometric shapes are included in this wooden puzzle: circle, square and triangle and two sizes of circles, that can be referred to as the small circle and big circle and can help child to begin to understand the idea of different sizes. Shape recognition is a basic underpinning of geometry, and an important preschool skill--give your child a head-start by teaching them young! DEVELOP HAND EYE COORDINATION as child practices putting puzzle piece into the inset, the child learns to both reach for the peg shape as well as place the shape directly into the matching inset. Different shapes present different challenges in terms of matching up the puzzle piece and inset. GRASPING EXERCISE knobs are perfect for little hands and help to develop grasp, and important aspect of fine-motor skills and also critical for developing the hand muscles to later be able to hold a pencil and write BEAUTIFUL WOODEN CONSTRUCTION these puzzles are made from European beechwood and painted with 100% non-toxic paint
