Act as an experienced early-years and primary school teacher. Suggest screen-free activities for children aged {{children_ages}} who love {{child_interests}}. We have {{space_and_materials}} and about {{time_available}}. Give 15 activities in a table with columns: name, best age, setup time, mess level, materials, what it builds (for example creativity, language, movement, or problem solving), and how to make it easier or harder. Mix quiet and active, solo and together, and indoor and outdoor ideas. Use materials most homes already have. Add a safety note wherever there are small parts, water, heat, or tools that need an adult. End with a simple weekly rotation so the best ideas don't all get used on the first day, plus three ideas that need no setup at all for the tough moments.
