I have 4 kids that go to public school and they are good students and they do well. One of five is probably the most gifted mentally but least motivated and seems better suited to online for now--very challenging for me being his parent ... very.

Anywho? I've got a 6th grader. We'd like something that allows him to finish curriculum/quizzes so that he can self-pace on courses.

* Khan Acadamy - So good. Love it, but lacks things outside Math.
* http://time4learning.com - the lessons are really rough to listen to.
* k12.org - good but no curriculum or quizzes.
