Simply Great
I have a 5 year old who loves puzzles and loves games. Thought Id Dragon Box a try, without any expectation that hed either a) like it, or b) learn anything.
Its been amazing to watch -- he loves the game, he has no idea hes following any rules re: simplification of equations. Well see (years from now, sadly) how well it translates -- unless I decide to start introducing algebra-as-algebra earlier -- but hes having a blast.
Really well thought out, great progression of concepts.
