I am also doing a rainforest theme for my classroom. I have found some that include: Reading Rainforest, Wild about Reading (this has an animal print background and book covers with big google eyes that looks as if are looking at a book), Hanging out in Mrs._____ Room (hall display), Mrs. _____ Bunch (Tree with a monkey and bannas), Wild About School, Wild About Books. These are just some that I have found, I have more but, I wrote them down and they are at school so I could decide which ones to use. Hope this helps.
