Grades: 8‒9

Students play games in which they use virtual algebra tiles to factor quadratic expressions. They play each game multiple times, with random challenges generated by Sketchpad, and work to improve their score. The activity concludes with students identifying the factoring strategies they used.

OBJECTIVES

- Students will use a grid of algebra tiles to factor quadratic expressions.
- Students will develop strategies for factoring quadratic expressions.
