Query: Great series, easy to use for parent/teachers, a few mistakes though

There are a few mistakes in this series, I will admit that. I don't get tooo crazy about them, as there are very few and if my kids don't agree with an answer, we find it together.These are easy to use, and I can tell you that's true because I hate algebra! The moment I learn something (again) about it, the new information goes right out of my head. My kids, however, are really getting it. There is gradual new information, there is just enough repetition.I highly recommend their other sets as well!My book:Whispers Of AngelsA Knight In Glendalough (The Aerleah Series)
