I don't know about Kumon, but I don't see Score being anymore drill and kill than Aleks. FWIW, DD8 uses both and likes them both. Aleks isn't appropriate for DD5 yet, but she will probably have learned enough by the end of her program at Score to start it if she wishes.
I do work with the girls a little after school. I want them to accept me in a teaching role in case I have to homeschool.
Although, both girls prefer to have someone else teach them. As they get older they just want me to be "the mom".
The Score programs have the same algorithms built in as Aleks so it is "self leveling" as well.
We do a lot of incidental learning and it seems as though that's where we are naturally progressing to.
