Exploring Parabolas

Description: In this activity students explore the graph of a quadratic in vertex form. Interactives are used to allow students to interact with the graphs of parabolas and understand the effect that each part of the equation has on the appearance of the final graph. Interactive practice is also provided to solidify the concepts.


Parabola Applets: In these applets students use sliders to explore the a, h, and k values of an equation of a parabola in vertex form.These applets were created with Geogebra.
