Solving Quadratic Equations Activity & Revisions (pp. 71--90)

Jackie McCarthy

Abstract


The author describes a classroom activity that had students solve quadratic equations in stations.  Students were provided with four different solution techniques and selected the `best' method for each equation. Then they created their own equations. The author discusses revisions to the activity based on her students' misconceptions and research.
