This is one of my favorite childhood books! The Miss Nelson collection is a must read to students in the primary grades and will keep them giggling from start to finish. A great book to teach students the importance of showing respect and appreciation, or they may just end up with a visit from Miss Viola Swamp. I would read this story to my first or second graders at the first of the year, while discussing behavior expectations and substitutes. This is also a great selection to study compare and contrast with character traits, as well as cause and effect with third graders.
