I recently bought this book to go along with my minilesson for Dr. Raulston's class. I am so glad I bought this. It is a very cute book that helps teach punctuation. I would use this in a 3rd or 4th grade classroom to help them understand the importance of using punctuation when they are writing. You could make the postcards that are in the book and have the students get into groups and try to figure out which punctuation is taking a vacation by the description given in the post card. You could also have your students come up with their own sentences using the punctuation listed in the book. I think the intended audience is students aged anywhere from 2nd-4th grade, but I personally would use it in 3rd grade.
