By: Raymond Briggs I don't know if this is something you could use or not. It is a book about a snowman who comes alive at night in a child's dream. There are no words with the story, only pictures. Maybe it is something that you could use to brainstorm ideas about writing about a picture.
I also love the book Snowmen at Night. It is by Caralyn Buehner. My kids loved it. I read it before break and then they made snowmen. She also has a book called Snowmen at Christmas and Snowmen All Year (I don't have this yet, but do plan to buy it).
The Snowman would be perfect. The book is wordless and may be hard to follow without adding your own narration, but you can find the video version on Youtube.
Also, you could ask your librarian at school for suggestions on snowmen books or check your online card catalog (OPAC).
I just did a quick search of my library and I have 37 snowmen books in my school collection! Even if there is just one book that the teacher may want for read aloud, she could check the others for a fun reading center for early finishers.
I am going to read the book The Snow Globe Family and have my students write If I lived if a snow globe...
You can get the book at Amazon
They will make their own snow globe picture to go with their writing. Very cute!
