So many to choose from! Here are some of our favorites (for both my sons and dtr):
Ginger Pye--- they really got into it, esp. with Carrie's ideas that go along with Storytime
The Sword in the Tree
The Cricket in Times Square (my boys esp love it, and we also read Tucker's Countryside after)
All Little House books are great (dtr)
Sarah Whitcher's Story
Key to the Treasure
Mr Popper's Penguins
All EB White books!
The Cabin Faced West (starts a little slow, but they got into it after a while)
McBroom's Wonderful One-Acre Farm (that is in the DITHOR pack, but I did it as a read-aloud for humor, and they LOVED IT. It is hilarious if you read it with the right accent!
I've switched up between some of the DITHOR books and the sets, as far as storytime goes. There are so many good choices! You really can't go wrong!
