Students produce original art (visual art, music, drama or poetry) that conveys an anti-bias or social justice message. Students then plan a public showcase of their work.

This is an art lesson incorporating the Art element of Value with black and white photography. We are also incorporating Language arts & social studies standards as well. Preview image: "iPad" by Sean MacEntee is marked with CC BY 2.0.

The problem presents a context where a quadratic function arises. Careful analysis, including graphing, of the function is closely related to the context. The student will gain valuable experience applying the quadratic formula and the exercise also gives a possible implementation of completing the square.
