Upgraded Solid Ash Wooden Sticks Teaching Aid: Made of high-quality ash wood, it includes colorful sticks and plates. Designed specifically for children over 3 years old, it helps develop hand-eye coordination and logical thinking through color matching and insertion and removal actions Safe and environmentally friendly material and craftsmanship: The beech wood is hard, sturdy and durable, with rounded edges and smooth surfaces without sharp edges. The environmentally friendly water-based paint has bright colors and is non-toxic. The length of the insertion rods is moderate to prevent accidental swallowing, and the hole positions of the inserts are precise to prevent loosening. This ensures the safety of children's operation Color perception and classification thinking: Guide children to insert the sticks of the same color into the corresponding holes, or arrange them according to a pattern (such as red-yellow-blue), thereby enhancing their ability to identify colors and make logical inferences Fine motor skills and hand-eye coordination: Grasping the rods, aligning them with the holes, and precisely inserting or withdrawing them, which helps to train the fine control of the hands, the strength of the wrists, and the hand-eye coordination ability Concentration and Parent-Child Interaction: Repeated practice helps cultivate patience and concentration; support family cooperative games (such as "Quick Matching"), which promote parent-child communication and social skills through interaction
