Letter walk: walk around the neighborhood looking for letters on signs or things that begin with that letter, and then fold down tab on the plate. This would make a great car activity too! Road trip games Good for the classroom too!
Reading chains: Every time a student finishes a book, they can write their name, title and author of the book on a strip and attach it to their class chain. Perhaps the class with the longest chain at the end of the year could get some type of reward.
