While apples got old quick, my mom still does treasure notes she received and loves to remember students of hers, as she reads about their exploits (college, jobs, marriages, babies) in the local paper.
That's why I really like a new product from Josten's (yes -- the picture and yearbook and ring guys) that I think will make an excellent teacher appreciation gift. It's a simple-to-make photo memory book that will make a great keepsake for a teacher. I know my mom would have loved it.
The class picture. Some candids from the field trip or the classroom. Shots from the class play. Good stuff. Cool idea for the room moms at your school, too.
