I agree, Flat Stanley is something I would have read in maybe second grade...not 4th. By then I would have found it way way too insipid.
I assume everyone means something different when they post here, "my child reads at x level". For some it is prob a full understanding like howler karma stated...and for some I suspect it is simply they can handle pronouncing the words, and go though a paragraph of such and such book without trouble...though the self drive to read the entire book is not there.
My husband is just finishing reading 5 Levels of Gifted..after I finished it too. What we were trying to decided is how many years above grade level son is to fit it to the tables in that book. But I suspect that what parents reported to author is as diverse as what people report on this forum. I wish these milestones were better defined. Does "began reading" mean first time they notice their first word...or first time they string a whole sentence or even a whole book together?
I guess I am just trying to define all these terms, because I am a stickler for that type of thing:)
