Some are home-made and some are store-bought. Some are funny and some are not. Sam wants to give just the right valentine to the most popular girl in the class, Tiffany. But what kind is the right kind? Mary Ann helps Sam figure out how to make all sorts of valentines. But will Tiffany even notice Sam gives her a special valentine?” This is a delightful book! We loved it. There is a surprise ending that will warm hearts of all ages. We immediately read it a 2nd time. It would be a great addition to any classroom and could be used in a unit on Valentine’s Day, feelings, friendship, and emotions. Pre-K. EL (K-3). ESSENTIAL. Reviewer: SL.
