Geometry of Great Buildings
A ready-to-teach curriculum module for high school geometry teachers that uses the Sagrada Familia, Hagia Sophia, and Taj Mahal to teach ratios, symmetry, polyhedra, and catenary curves in a project-based, real-world way.
High school and introductory college geometry teachers looking for project-based material
- Slide decks and printable worksheets mapped to Common Core and equivalent geometry standards
- Step-by-step derivations showing how Gaudí's 7.5m module and dodecahedral stars actually work
- Short on-location videos of mathematicians visiting each building to point out the geometry
- Auto-graded quizzes and a capstone project where students measure their own local landmark
Schools are moving toward 'math in context' curricula to fight student disengagement, and the Gaudí centenary gives teachers a built-in cultural hook to anchor the year.
Architecture-themed geometry PBL exists and is bought (19,000+ 'real world geometry' resources on TPT, multiple dedicated 'Geometry In Architecture' bundles), but the specific Sagrada Familia/Hagia Sophia/Taj Mahal framing is niche and the source HN thread had only 3 points/0 comments, indicating weak organic buzz.Real World Geometry results - TPT ↗Sagrada Familia Educational Project ↗
Saturated market: dedicated TPT stores already offer 'Geometry Transformations Project with Real World Math Using Architecture Design', 'Scale Model Geometry Project', Taj Mahal lesson plans on Scribd, and broader geometry-in-architecture bundles — leaving little uncontested space for this specific three-building module.Geometry Transformations Project with Real World Math Using Architecture Design - TPT ↗Mathematics in Taj Mahal Design - Scribd ↗
TPT resources typically sell for $5–30; teachers have small PD budgets and the category is crowded with cheap/free alternatives, capping unit economics. Premium bundles (Termeric, Outschool, district licensing) offer upside but most teacher-creators earn modest side income.Termeric — Buy & Sell Ready-to-Teach Curriculums ↗How to Sell Lesson Plans & Teaching Materials Online ↗
Gaudí centenary is a 2026-only cultural hook, but architecture-as-geometry content and the Sagrada Familia education program have long shelf life; demand will taper sharply once the centenary passes unless repackaged for ongoing curriculum use.Sagrada Familia 2026: Gaudí Centenary Key Events ↗Educational project - Sagrada Familia ↗
Trivial to build — lesson plans, worksheets, and simple printables; aligns with formats teachers already buy on TPT, no engineering required; existing creators ship comparable products.Geometry Transformations Project with Real World Math Using Architecture Design - TPT ↗
