The AAC from A to Z series continues with another explainer video; this time about expanding the functions of communication your AAC user can use. This is about moving on beyond simple requesting and/or choice-making, so that your AAC user can say more about what (s)he really needs to communicate.
You might take a look at the first 3 videos in the series: A is for Aided Language Stimulation
and C is for Core
and P is for Planning
I also have many AAC implementation resources in my store's AAC Category Section
