Shelf Talkers is one of the first centers I started using regularly during library classes. I got this idea from The Centered School Library. I tell the kids these are little advertisements for books they have enjoyed and want to share with other readers. So far, students at all grade levels have done a great job creating shelf talkers for our library!
In our library, we use 3"x5" index cards, folded in half. After students complete their shelf talkers, I laminate them and tape them to the shelves in front of the book they advertise. I have definitely seen an increase in check-outs for the books that are "advertised". Here are some shelf talkers you can see decorating the shelves in my library:
