I have used story books with 1st class all the way up to 6th class. You are never too old for a good story book! I adore picture books, and would just teach using these for the whole year if I could.Novels are a firm favourite too.
This post includes a list of story books and novels I have used with first and second class which I found great for thematic planning
1.Not strictly picture books but anything by Roald Dahl will always be well received, particularly
The Magic Finger
Fantastic Mr Fox
2. Horrid Henry
3. I Need to Wee!
4. Frog in Love
5. Anne Fine's short novels are all good for this age group- nothing too exciting but an appropriate reading level.
6. The Giggler Treatment by Roddy Doyle
7. The Snail and the Whale
8. Anansi the Spider
9. Beowolf the Brave
10. Michael Morpurgo's The Castle in the Field.
