Elementary School Math Curriculum

If you were in charge, what would elementary school children (that is, grade 7 and below), be expected to learn before going to high school.

#27:  No.  Do you mean Jean Piaget, "a Swiss philosopher, natural scientist and developmental psychologist, well known for his work studying children and his theory of cognitive development"*?  Surely you're not suggesting that dumbing our children down (through a process of reacting to diminished expectations) is instead the natural order of development.
