I have used tis project for the last few years in Algebra 2. Students
create their own word problem, write the equation, find the roots and maximum, graph it, explain realistic roots/domain/range, and compare it with a 2nd scenario. The second scenario is same thing on another planet - Yes, I still consider Pluto a planet. :)
This zip file contains a complete project, example word problems, a rubric, and powerpoint template. I usually check a students word problems before they continue with the project.
