Charles Cook, author of our math curriculum, is a high school teacher with a proven track record of success in both the class room and publishing.  A passion for teaching advanced mathematics and a clear vision of both its content and presentation shapes Cook’s curriculum that we present here.

A quick look at this curriculum reveals that it definitely was not created by a committee: it discards the traditional approach of bloated, politically correct textbooks and opts for day-by-day lessons that are actually ‘doable’ in a single day.

Cook has carefully crafted each of these free, Algebra I, Geometry, Algebra II (alg), Pre-calculus( pre cal), and Calculus, lessons so as to cover all required topics in a single school year... and all with continuing built-in review and daily tweets.
