Check out this free App below from Prentke Romich:
Language Lab: Core Words is the first in a series of apps from the Prentke Romich Company based on developmental stages of language development. In stage one, language objectives include directing the behavior of others and the course of any activity with words instead of behavior, expanding the ability to request and direct action, direct using negatives and identifying familiar people by their name. This exciting app will address all four language objectives to help early language learners as well as children with expressive language delays who use augmentative and alternative communication methods. The icons for these core vocabulary words that are introduced throughout the app directly correspond with the Unity language system on the communication devices by the Prentke Romich Company but can be easily used by all.
