Xia Xiaowu, a great math teacher from New York City, sent this awesome activity that has kids figure out what the sum and product of a quadratic’s roots are by using the Quadratic Formula.
Now, I know that many of you know that sum and product of roots is sort of “on the way out” in terms of content being assessed on both CC Algebra I and Algebra II, but this project is really neat and strengthens student understanding of quadratics and the quadratic formula. So, it is well worth a look.
Thanks so much Xia!!!!
