Quadratic Formula Derivation

06 October 2014
My Geometry Honors students have been cutting and gluing so much lately.  I think I’m going through a crafty phase in my teaching.  :)  I thought my Algebra 2 Honors kids might like to get in on the craftiness.  


I typically derive the quadratic formula by hand for my students on the board while they follow along.  This year, I typed up each step in the proof and had my students derive it themselves.  It worked so well and they enjoyed doing it.  You can download the file that I used.

When we were finished, I showed them a couple of videos to help them memorize the quadratic formula.

This was my student's favorite.



Overall, it was a fun day in Algebra 2 Honors.
