Reflection: Connection to Prior Knowledge Keys - Section 1: Set the Stage

 

My students surprised me during this part of the lesson because not one of them could come up with a real-world example without additional prompting.  One student almost immediately identified the equation as a quadratic function, but then couldn't give an application.  When I asked the rest of the class to help him they were equally lost.  It took several directed questions like "What does the graph of a quadratic function look like?" and "What real-world application might make a graph like that?" to get my students moving forward.  One suggested a football thrown down the field makes a shape like that and asked if that would work.  I put the question back to the class rather than answering it myself, and they determined that you could graph distance and height to get a parabola.  After encouraging further discussion about possible applications, I moved on with the lesson, but now I know that my students may not have much experience modeling real applications with functions when they get to my class.
