I love this book. It's so simple and so cute! It is about a little boy who believes his not-so-fun teacher must be a monster. But then he interacts with her outside of school and realizes that the person he sees in the classroom isn't all of who she is. Students in 1st and 2nd grades will love this adorable book (and some will relate to it)!. This book would work wonderfully alone as a read-aloud for emergent readers. I would use the book as a read-aloud, and them introducing class discussion by asking students if they have been in similar situations. The story will teach a valuable lesson about not jumping to conclusions and judging people before really knowing them. There's a great lesson in there for every age!
