Best Teacher Ever by Mercer Mayer is part of his famous “Little Critter” collection. In this book, Little Critter wants to show his favorite teacher how special she is – and he does, in true Little Critter fashion. Even though this is a “children’s book,” any teacher is sure to love the message behind it. As an added bonus, it can become part of an elementary teacher’s class library – and honestly would probably be appreciated by older kids, too. This is a great, inexpensive way to show a teacher how much she means to you. Click the button to check the current price.
