Interesting, Grinity.
DS7 is only starting 3rd grade level in Aleks so we are still far from that level, but can anybody who tried it out tell if it is reinforcement (ie. assumes that the concepts have been taught), like Dreambox (which my son loved) or includes at least the basics of teaching inside the program (like Aleks and Khan Academy) and whether the lessons are "wall of text" (like Aleks, which my son finds meh!, mostly because it requires him to read way too much text in between math stuff) or spoken out loud (like Khan academy).
