Here is a instructional activity that focuses on analyzing the discriminant of a quadratic equation to determine the nature of the roots of the equation. It consists of a three-column organizational chart to complete. The first column states a scenario for the value of the discriminant, such as less than zero or equal to zero. The task for the student is to complete the last two columns, which ask for the nature of the roots and the number of x-intercepts of the graph for each given scenario. This resource can be used in a number of ways. It would be a good way to summarize concepts after an introductory lesson on the discriminant, it could be used for learners to record their observations during an introductory lesson, or it could be used as a review tool in the upper grades.
