the book Welcome Comfort? I read that book to my class today and I loved it. I thought it was a great story. The kids had it figured out way before I did when I first read it. If you haven't read it, please add it to your read aloud collection. Great Christmas book.
P. Polacco is great for a 4th grade author study. She wrote many more books than have been listed here, including Thundercake, Uncle Vova's Tree, Rechenka's Eggs, The Bee Tree... and so on. A lot of her books are based on her culture and personal family history.
Not much to say on this thread, except I have loved every book I have read by PP. I will check around for Welcome Comfort. I read The Bee Tree every year at the beginning of school, assigning the children to be characters in the story. It is great.
