"We Got My Brother at the Zoo" by John and Ann Hassett

This book has a pattern of starting out by saying Did you know we got my brother from _____?  It also has further narrative to explain each different place where they got his brother.  I think I would us this as a writing prompt.  I would allow my students to start out with a similar line and then have them write to elaborate on that first line.  I could also just have them plug in different words into the question for younger grades to get them brainstorming.
