## Introduction

The main focus of this module will be on using the kinematic equation h(t)=1/2at2+v0t+h0 to introduce students to graphing quadratic equations and how each parameter affects the graph. Using kinematics to introduce the topic gives students a concrete example so that they can better visualize how a, b, and c affect a quadratic graph. Instead of simply discussing the general parameters or features of the graph, students can use their intuition about something like a ball flying through the air to visualize how changing parameters would change a graph. So, instead of thinking how b would affect the graph of a quadratic equation, students could think, "what would happen if I threw two baseballs into the air, but threw one harder than the other?" the students would think in terms of the context of the problem, "would the ball go higher or lower? Spend more or less time in the air?" and use their intuition about the world around them to understand the idea first with the kinematics example and later in a more general and abstract case.
