We started using AinA this fall, and I'm enjoying it. The chapters are easy to do, and I appreciate the review questions (Although I'm sure I could come up with them myself. Just glad that I don't have to. One less thing, ya' know. :D) I really like their reader suggestions. I've added in some extra art projects here and there and extra chapter books which are slowing us down a bit, but I don't mind if we go into the summer or next school year.
