Once students have learned how to solve a quadratic by factoring, graphing, completing the square, and the quadratic formula I assign this activity. It takes a total of 50 minutes. I assign each of my students a different quadratic. They then have to solve it four different ways on the sheet provided. Once they solve it four different ways on the sheet provided. They will see that if they do it correctly, they should get the same answer four times. Once they solve the quadratic correctly on the sheet of paper with the quadrants, I give them a poster to make a poster version of their quadratic solutions. It's a great way to reinforce that quadratics can be solved four different ways.
