The Slide Small Wooden Ring (I460) is an infant and toddler manipulation material designed to support early hand-eye coordination and the development of the palmar and pincer grasp in children from approximately 6 to 18 months. The smooth wooden ring slides along a fixed rod or track, giving very young children a clear cause-and-effect interaction that is appropriately challenging without being frustrating. It works well in a nido or toddler shelf arrangement where you want low materials with high repetition value.
