Right now I am reading two books to the classes that visit the library.
Pancakes for Breakfast, by Tomie DePaola, is a simple easy to read book, because it has no words! Well, not totally. The only real words in the book are a recipe for pancakes. The rest of the book can just be read by looking at the pictures.
For some of the older classes we are reading:
which is a wonderful disgusting book about Mr. and Mrs. Twit, and the terrible things they do to each other. Or that they do to monkeys. Or birds. Or little boys. Really anyone. With lots of bizarre words made up by Roald Dahl and some strange scenarios, it has been a great read-a-loud so far.
