Day 28 - Last Day of Quadratics

The students covered the ideas behind -b/(2a) for finding the x coordinate of the vertex. The students struggled with the understanding of where this value came from. Unfortunately, I do not have anymore time in class to cover its derivation, but I will allowing students to come in at other times (lunch, after school, etc.) to think about this a little more.

I really need to start taking more pictures in class...
