Gretchen Hanser's article "Making Simple Books" in OT Practice has some fun activities. I love the "fluffers" used to make turning pages easier. She descirbes these on her web site: http://www.creativecommunicating.com/tips-pf.cfm
The article also describes how to make books out of food boxes and pages filled with plastic bags of materials such as dried peas to feel and view. As Hanser concludes: "students with disabilities need access to a wealth of books-no different than students without disabilities. Occupational therapy practitioners can make books thatr not only meet student's sensorimotor needs, but also their literacy needs."
