The Makedo EXPLORE Toolbox enables one or two children aged 4 and up to construct imaginative creations using cardboard. Cardboard, a material recognized by the National Toy Hall of Fame, is widely available and can be folded, cut, and punched while remaining sturdy. It is also reusable and recyclable. Designed for small groups and creative settings like home play or building projects, Makedo encourages hands-on learning while promoting sustainability. The open-ended nature of the system fosters independent making, allowing children to engage in imaginative play with their own creations. By experimenting and building, children develop STEM and STEAM skills. The reusable tools support endless construction possibilities, reinforcing creativity and problem-solving.
