Using Desmos to Support Conceptual Understanding of Quadratic Equations and Their Graphs

Abstract

When teaching secondary mathematics, there is often a struggle to distinguish true understanding versus the ability to follow a memorized procedure. This commonly occurs in Algebra I content of solving and graphing quadratic equations. Engaging students in Desmos interactive graphing learning activities has been shown to help deepen students’ understanding of such concepts. This curriculum project is designed to deepen students’ understanding and fluency of quadratic equations by including hands-on activities that support students discovering relationships and patterns between quadratic equations and their corresponding graphs. The unit plan aligns to the New York State Common Core State Standards.
