Relief Teacher Tip I keep a post it note in the inside cover of the books that I read to classes. I record which classes I've read the book to & which ones I've done an activity with the book too. It's an easy way to keep track of which classes you've done what with! I also have a checklist of activities and classes, that I keep in my folder. The post it notes are just a quick way to check when I'm choosing books to pack for the day!
