These masonry buildings provide a rich starting point for developing engaging STEM curriculum and build challenges that connect play to real-world engineering and architectural history. They fit naturally into SAMANSIC's Monument Kit with historical build guides, Engineer Kit with CAD access, and Classroom Kit with teacher curriculum and assessment tools.
