I love this book and movie! It definitely gets everyone in the holiday spirit so I would use it around the Christmas season. The Lexile level is 510L. I would use this in a 2nd or 3rd grade classroom. I would first read the book aloud to the class so that they know the story. Then we would sing the song together while they all have copies of the lyrics. Then we would go through the lyrics and find the similes and metaphors and write them on a T chart. There are so many fun things to do with How the Grinch Stole Christmas!
