How about the Wayside School series by Louis Sachar? DS started reading these when he was 5. He has read and re-read them many times. "Holes" by the same author is very good too. There's also a movie on it. Another good, old classic I can think of is The Phantom Tollbooth by Norton Juster.

To add: DS loves the "Choose your own adventure" series too. We are very lucky that we managed to find these in the library (even though they were torn and tattered!). When DS8 didn't know what else to read back in grade one, his teacher recommended him the Encyclopedia Brown books... which he found in the libraries too and devoured all of them! wink
