My 9 year old DYS has a lexile from MAP of 1350-1475. There is literally nothing that is age appropriate AND interesting. I do not think he should be reading about the history of Jack the Ripper from a college level perspective.
My dd was in about that Lexile range at the same age. A search for "humor" in that range in the online list produced a single scholarly treatise on humor, one that looked incredibly boring. So we've just not bothered with dwelling on her Lexile range. She is now 13yo and still reads a huge amount, most of it "below her Lexile level," but she enjoys it all immensely.
