This is a great lesson that I use after solving by factoring, completing the square and the quadratic formula. Administrators love to see this lesson because it is a great way to differentiate.
There is a ticket out the door included that students will need to fill out on the day before you do this activity. An answer key is provided that will tell you which stations students need to go to depending on the questions that they miss.
There are 6 different stations - there are 2 of both solving using the quadratic formula and completing the square as those tend to be the ones that students miss the most of.
An answer sheet is included for the students where you can fill in which stations each student is to visit or you can choose the number for each to visit.
