Geometry and art: Art museum post-visit
This is the third lesson in a three-part unit integrating math, writing and visual arts. In this integrated lesson, students apply their knowledge of geometry by organizing and displaying information in graphs with correct labeling. Students then compare and analyze graphs. Finally, with this information students create a geometric design.
