Grade level (age) ?
From Talk:Martian Math
While there are possibilities (Martian Math, Neolithic Math, Supermarket Math are great titles!), but I am not sure what grade level (age) these materials are for?
That's deliberately unspecified. I'd say "for adults" if pressed, to counter the stereotype that "education is for children only".
