Why this is submission-worthy - Students manipulate factors, tiles, roots, graph, and artwork as one system.
- The unit count becomes visual art, so factoring has a creative payoff.
- The same model supports exploration, explanation, and quick assessment.
- It is generic: changing two factors creates an entire family of quadratics.
Classroom prompt
Create a bloom with exactly 12 unit petals. Explain how its rectangle, graph, and roots prove your equation.
