My year 7 DS has been given a reading age of 15 years 6 months on an accelerated reader test. i know he has to read books and do quizzes on the books.
I've looked up the books he has recently read on the AR book finder and they have come up as mostly upper years and 5 or 6 point something. Some books he has read in the last few weeks are 'Ready player one', 'the book of dust', and he has re-read the 'his dark materials' series. Other books like 'children of time' and 'a long way to a small angry planet' were not on there. I looked up what was available at the higher levels and I don't see him wanting to read most of it.
So, should he just keep reading what he is already reading? What is this program meant to achieve?
