Efforts to force kids to take algebra at lower and lower ages, such as attempts in California to make all kids take algebra in 8th grade.
What exactly is this "algebra" that they have to learn?
As another person in the comments, I don't find starting algebra at the eight grade outrageous, but maybe the topics behind the general term are a bit different.
I've had what's called "algebra" here since grade 7. We had equation and inequality solving, single-argument functions, linear functions, monomials and polynomials. And in grade 8 we got to factoring polynomials (short multiplication formulae) and solving quadratic equations.
What do people in the US normally have at that age? And what is in the California attempt?
