» Is this a program that can be used to replace a text book?

This is a resource designed to help teachers develop stronger conceptual understanding in math in addition to video tutorials on how to teach math conceptually and visually to help students build their own conceptual understanding. Because most of us teachers were not taught this, we often need a lot of re-training or re-learning in order to feel comfortable switching from teaching procedurally to teaching both conceptually and procedurally.

The videos are intended for teachers, not for students.
