Symbol Resources (@SymbolResources) is an online resource created and managed by Tina Voizey to help teachers, speech-language therapists, parents, and others who are interested in creating and using symbol-based materials to support the language development and learning of individuals who have special needs. This site features information about best practices in using symbols, guides on how to use popular symbol software, & FREE resources supporting monthly themes as well as life skills and academics. The resources that are available on Symbol Resources are created in Boardmaker, Communicate: In Print and Matrix Maker.
This site is one of a few activity shares geared towards special education that I have recently discovered. It's great when we don't have to recreate the wheel when it comes to creating adapted/modified instructional materials!
