I so appreciate the wisdom of the teachers of ClassicalU and am especially enjoying this course! Due to my background teaching physics, I realized the importance of this depth of mathematical understanding and have taught math so far to my children using many of the techniques that Mr. Elizalde proposes. I would love to continue this method as we begin to explore Algebra-Calculus in the next year or so. Is anyone familiar with some resources/texts that would continue to introduce material in this way? I am considering VideoText algebra now, but would love any opinions from the forum!
