Shari, Did you find that there is some repetition in the levels? I'm not sure where to start DS8. I read on their forum that if I sign him up for 3 on math and 4 on language arts, or vice vesra, I'll have access to both levels at once. (And I emailed them about that today).
DS really liked it (probably b/c it was easy and fun). Not sure if I should just let him whip through 3rd grade to reinforce his skills and cover anything he might not have had yet, or go to 4, 5 or whatever. Does it spiral?
Did you print out the worksheets?
And what have you used as a good mix of work/fun?
Thank you, everyone, for responding.
