For 25 years Social Thinking has been bringing books, curricula, conferences and on-line training to the social learning community -- parents, educators, and interventionists. They provide frameworks, tools, skills and a shared language to improve social competencies.
Social Thinking is generously offering many of their materials to families and educators for free right now. I encourage you to check them out and, if you wish, to share with your child. There is something here for everybody.
Social Thinking - free stuff
(Perhaps you have heard your child talking about Zones of Regulation, Body in the Group, the Group Plan, Expected or unexpected behaviors, Whole Body Listening, Rock Brain, Super-Flex? These are concepts from Social Thinking.)
