It's a Solving Quadratics Mystery! Students are given 4 mystery problems. Each problem has been answered incorrectly. First, students must PROSECUTE the wrong answer by explaining why it is wrong. Next, they must find the correct answer and DEFEND it by showing all of their work. Each mystery is a different representation.
This activity is great for reviewing for a test! This activity addresses the mistakes that students make when solving quadratic equations/problems. Students learn from their mistakes. Hopefully, by addressing the mistakes from the beginning they will not make the same mistakes again. It's Math on the Spot!
