I really like Abeka for Math for grades 1 - 4 (I get grade 1 for my kindergartner). The lessons are very user friendly - my kids like the pictures too.
Lots of review but the lessons progress in an easy manner. They are advanced but make it easy for a child to excel.
My Comments: I have heard good and bad about Abeka math. You're right, though, if a child wants to excel, then Abeka will give them the challenge.
