Tomie dePaola is another classic author of children's literature. I have used his books time and time again in the classroom, whether for simple story reading or for teaching a lesson. He is known for retelling favorite tales, such as in his Strega Nona series. His book Nana Upstairs, Nana Downstairs makes me cry every time I read it.
I also really like his books about the holidays. For Christmas and Easter, he is able to provide a balance with the religious aspects of each holiday. He also has written about other holidays.
I also admire dePaola for doing his own illustrations.
Some of the stories are too advanced for the young children that I teach. But most of them are appropriate for the elementary age. Check some of them out and see what you think.
