This material presents children with a wooden pegging box alongside a screw interchanger component, offering two distinct tool-use experiences within a single practical life work. It supports the 3–6 classroom by refining hand strength, pincer grip, and the coordination required for real tool use — skills that transfer directly to dressing frames and later writing readiness. Teachers looking to extend their tool-use sequence beyond hammering alone will appreciate having both mechanics available in one compact material.
