Core words give us power in communication. Adding core to fringe allows the communicator to say much more beyond labeling the item: e.g. - play ball, get on base, big tent, small campfire, get in/out of sleeping bag, I like it, I don’t like it, do more, etc.
Let's Teach Core is a great resource that gives you ideas on how to introduce a core word, how to model it, what to expect, and how to grow language! Each handout gives you multiple ideas for fun activities to engage your AAC learner with core vocabulary and language.
