It is nice to meet you Caroline! My youngest has just started AR too, he is in 2nd grade. He doesn't do too well on the tests, even though he is a bright little guy. They don't require a certain amount of points, just that they get so many 100's on the tests. I think that is crazy too. His teacher doesn't put too much pressure on them though. Not like dd's 5th grade teacher.
It can be good, but like your child, dd only cares for a certain type of genre-fantasy books. She is reading Black Beauty and the Little House set (finally-after trying to get her to read it for years) for this quarter. I can tell she is miserable and would rather be reading something else, but these will get her the high points.
Anyway, I look forward to seeing you on these boards!
