Here are starting points for learning each of the apps/languages our students use to communicate. These websites provide wonderful resources on both learning how to use the app and how to incorporate AAC use into the classroom. As Liz also mentioned, her and any other speech pathologist at 208 would be happy to sit with you and your staff and teach you more on how to use the device, model language use, and provide opportunities in the classroom. Communication happens all day and in all environments!
