Children love this book because green eggs seem impossible to them! The teacher could read this book to the class and then have green eggs and ham ready for them to try and eat! Watch for allergies, of course! This is a great book for a time you might be learning about rhyming words. After reading the students might could write down all the words they remember from the book that rhymed and then come up with some more words that rhyme with those. The food would just be to make the lesson stick ;) intended audience would be 1st-3rd grade.
