I love your program and am thoroughly impressed with its logical and strategic methodology. It makes so much sense. It’s amazing to see my sons understanding place value, seeing patterns, and applying these mathematical principles to other situations.

Thanks Dr. Cotter. I tell everyone I know how wonderful this program is because it smacks against the ridiculous notions perpetuated [with] math systems generation after generation.
