When my younger son was first and second grade it wasn't upsetting to him to read a book with a lower lexile. If he was reading on his own time he would read stuff below, at or above his lexile. The problem was if it was a lower lexile and he was having to read it slowly with a group or the whole class. So at that age his goal was to read every Goosebumps book ever written (there are hundreds) and generally he could read them in one sitting. Now if the class was to take that same book and drag it out for two weeks---would have gone insane. So many times throughout elementary school it wasn't the lexile but the pace. Stone Fox....great book...good for him to read. But it was a short story to him and a novel to the other kids.
