I've been considering Descartes' Cove for my almost-7yo, too. He's doing geometry and loving it right now--we did parallel lines cut by a transversal yesterday, and he got a big kick out of seeing all the congruent and supplementary angles in the "puzzle." Then I read this thread and it made me think that the DC game might be right for him after all...

So please keep us updated on how your DS likes it as the newness wears off, would you, Cathy? Thanks!
