Mind your Manners B.B. Wolf
I would introduce this book to my class at the beginning of the school year to help students with their manners. If the students struggled with manners I would read it throughout the school year. The book is about B.B. Wolf (the big bad wolf) and how he goes to a tea party and has to use his manners. He burps but says excuse me before the burp and everybody turns to him.
