### Intro to Quadratics - using technology

With the new Common Core Algebra I, we teach polynomials first then go into quadratics.  The idea is good - it gets them to factor first and hopefully make the Quadratic chapter easier.  We shall see.  They weren't so strong with factoring.
Well, after they found or borrowed earbuds.  They are supposed to bring them every day.  They are supposed to bring a pencil every day too and that often doesn't happen.  It is May, we are still working on the small things.
Mario is on youtube and its description says it is a "good culminating assignment".  I liked the idea of starting with it because it might grab the students and I think it did.  It had them looking at the shape of the graph, if it opened up or down, how it gets compressed or stretched, and the vertex.  So, they should be ready to go with some important vocabulary for tomorrow's class.
The Angry Birds video talks about the zeros of the graph.  I am hoping the students might see the connection between the factoring we have been doing for weeks and the zeros of the graph.  It is a big "jump" for them but I will cross my fingers.
And, the last two, have the students watch and graph the swinging process.  It will be interesting to see what their graphs will look like.
When I first handed out the graphing homework after the Polynomial test, they said "Oh, graphing, we haven't done this in a long time.  This looks easy."  Okay, so if I can bring all this together - factoring and graphing, maybe it will be a good way to wrap up our Algebra I year.
