## Reflection: Grappling with Complexity Quadratic Function Applications - Section 2: Guided Practice

This lesson is a good way to push students to think deeper about quadratics. It also answers the question that math teachers always get: “when will we ever use this in real life?”  Since these can be hard to visualize, it’s extremely helpful to draw a picture. A quick sketch to show the curve of the parabola goes a long way to show help students conceptualize what’s happening in the problem.  This is also a good place to infuse technology, especially Geogebra, to reinforce the curve trajectory.  This lesson is difficult for some students so I suggest either pairing strong students with those who struggle or creating a group of struggling students who you can focus on helping.
