Many school districts in Massachusetts, including ours, use Everyday Math (EM) as the elementary school math curriculum. The authors of EM have objected to the Common Core Math Standards http://pqme.org/uncategorized/everyday-math-objects-to-common-core-standards/ , but now that many states have adopted them, including MA, EM has come out with a Common Core edition of its curriculum http://everydaymath.uchicago.edu/teaching-topics/standards/ . I don't like EM much (it jumps around too much), but maybe the Common Core version will be a slight improvement.

Are there any schools that adapt EM to the needs of gifted students?
