Working in groups, pupils plot three points on the coordinate plane representing three different parabolic paths. Using a calculator, they determine the quadratic regression equation for their models. Each team then figures out the vertex and a fifth point for the parabolas before using their creativity to make colorful graphs.

Instructional Ideas

• Alter the activity, have learners draw the parabola on graph paper instead of using technology

Classroom Considerations

• Requires access to ActivInspire
• Assumes class members are comfortable with finding the vertex from a quadratic equation

Pros

• Contains directions on how to enter the information into the program
• Includes a self-assessment rubric for pupil use

Cons

• None
