Books to entice 3rd & 4th graders with chapter 1:
Judy Blume books (Fudge)
Trumpet of the Swan (flows nicely for a read aloud)
From the mixed-up files of Mrs Basil...
Dinosaur Cove (good for lower level readers)
Roald Dahl books
I've read dozens of really good books to DS this year. I'll come up with more surely.
