what math program/curriculum did you use with it? my kids are 5.5, will be 6 this fall.
i'm only just starting to use FIAR with my 4yo daughter, I didn't know about it when my son was young. But I can tell you what math program we're using, and we're using it no matter what other programs we end up using for other areas -- RightStart math. It's absolutely the best. :)
