What they do at my childrens school is both ways. It is true that in the U.S public schools they must show their work. At my childrens school the teacher does not care how they get the correct answer as long as they are not cheating and he does teach rapid math, math tricks , vedic math etc... but to help in case the kids go to public schools he teaches them the method of showing work. Funny though the kids at this school are in the top 1 percent in the world for math and it is such a small school.

You get not just addition, subtraction, etc, you get a wide range of topics... At the moment my son is working on fractions, algebra, pos/neg numbers, long division and such. I like that he can move at his OWN pace and if he needs extra practice in some areas he gets it......
Tried Firefox, explorer, and google chrome .... none of them worked...
