I would be grateful for any suggestions.
My DS is in first grade and his teacher uses the A to Z leveled readers. He has the same level reader as he did last because to get to the next level the children have to state the characters, theme, and what happens in the beginning, middle, and the end. He reads each book in about 30 secs and declares it to be too easy (which he did last year as well). If you ask him any questions, then he states that he doesn't know.
The thing is he actually had a book from last May (he remembered and I didn't), and he told me details about the book before opening it. He reads for pleasure books at a much higher level, and often will discuss plot details that interest him (days, sometimes weeks later). DS had a hard time completing assignments even coloring assignments last year because his pace is slow and careful. If you ask him questions about what happened during the day he will say he doesn't know. Usually if you ask about specifics he will say he doesn't know and then answer.
