Students work in teams to solve quadratic equations by factoring and completing the square. The game is short, quick, and a fun way to review. The teacher presents teams with a problem to solve. Students solve and then race to pick up the matching answer card. There are enough answer cards for all teams but one ... one short! The game addresses these CCSS:
• CCSS.Math.Content.HSA-REI.B.4a Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x – p)2 = q that has the same solutions. Derive the quadratic formula from this form.
• CCSS.Math.Content.HSA-REI.B.4b Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
