I walked away from the Calaba conference with three books. My favorite being Visual Support for Children with Autism Spectrum Disorders by Vera Bernard-Opitz and Anne Haussler. This book is full of ideas and tons of pictures. What I like most is it has tons of ideas for lower functioning children. I also picked up Visual Strategies for Improving Communication by Linda Hodgdon and lastly I picked up Social Skills Solutions A Hands on Manual for Teaching Social Skills to Children with Autism by Kelly McKinnon and Janis Krempa.
