Graph Quadractics with Absolute Ease (VIDEO!)

Why do we make students suffer so when it comes to graphing quadratics? Why memorise the vertex formula x = -b/2a? We make it all too hard! Look here for the natural -and easy – way to graph quadratic curves.

  Written for educators - and their students too! - this website, slowly growing, takes all the content Tanton has developed in his books, videos, and workshops, and organizes it into short, self-contained, and complete, curriculum units proving that mathematics, at all points of the school curriculum, can be joyous, fresh, innovative, rich, deep-thinking, and devoid of any rote doing! Let's teach generations of students to be self-reliant thinkers, willing to flail and to use their common sense to "nut their way" through challenges, to assess and judge results, and to adjust actions to find success. (Great life skills!)
