How Many Sentences Can You Make?

To the left is a board with 20 core words on it.  Some people wonder how many things can be said with 20 words.  I thought I would give it a try:

1. I like you.
2. You like me.
3. I like it.
4. I like that.
5. I want some.
6. I want more.
7. I want some more.
8. You want more.
9. You want some.
10. You want some more.
11. I want that.
12. You want that.
13. I want help.
14. You want help.
15. I want (to) go.
16. I want (to) go in.
17. I want (to) go out.
18. I want it.
19. You want (to) go.
20. You want (to) go in.
21. You want (to) go out.
22. I am all done.
23. You are all done.
24. You go in here.
25. I go in here
26. I like (to) go out.
27. I like (to) go in.
28. You like (to) go out.
29. You like (to) go in.
30. I want you (to) stop.
31. You want me (to) stop.
32. It go on here.
33. It go out.
34. It go in.
35. What (do) you want
36. That what I want.
37. It is what I want
38. I want some in here.
39. You want some in here.
40. What?
41. What go(es) in?
42. What go(es) out?
43. What is here?
44. Mine is here.
45. It is mine.
46. What is that?
47. Some like it.
48. Some like that.
49. Not on this board.
50. It not on this board.

Obviously my list assumes facial expression to imply a question versus a statement, but 50 possible sentences from 20 squares really increases that value of what some call a limited about of "real estate" on a communication board.
On the right is a 25 word communication board.  (It happens to be a photo of a poster a family uses to model core words and sentence building for their AAC user.)  This board is a print out from a dynamic display device, so abox is lost to "back", although back can certainly be used as a word as well.  By adding "not", "who", "that", "eat", and "now" to the above board how many more sentences can we make?

So with 25 core words that is a total of 200 different things that can be said.  There are definitely some missing from my list too.  Feel free to add the ones missing to the comments.  Imagine how many things could be said with 30, 35, 40, 50 or 100 core words?  20 Core words is absolutely a starting point in working towards more self-generated language.  It has it's shortfalls: you can't say everything, there is no way to provide context (excluding multi-modal communication like pointing, eye pointing, gestures, nodding/shaking a head or a set of fringe vocabulary), there is no way to provide verb tenses (and therefore give context as to time) and 20 words is only a teeny, minuscule portion of what there is to say in the world.  
An intuitive and attentive communication partner can allow an AAC user to guide the conversation by asking clarifying questions, such as:

AAC User:  I go there.

Partner: You went there?

AAC User:  (Using gestures) No. (Using board.)  I want go there.

Partner:  Oh, you want to go somewhere?

AAC User: (Using gestures) Yes. (Using board) You help I (me) go there.

Partner: You want me to help you go somewhere.  Somewhere in the school? 

AAC User: I go eat.

Partner:  You want me to help you go to the cafeteria!?!

AAC User:  (Using gestures) Yes. (Using board)  I go eat now.  You go eat now.  Go eat there.

As you can see it takes some work on both sides, but try saying all that if you had twenty-five buttons that only had complete sentences like, "I want to listen to Raffi" and "I want to go potty"!  Core words do not have to replace pragmatic, phrase or sentence based alternative communication, but they are an excellent add-on to those systems.

Students can be taught to "try to tell me with your core words" when they cannot find a way to say what they want to say within their other pages.  If a core word page set is linked to a more pragmatic phrase or sentence based set of communication pages it might even be faster to say "stop" or "more" using the core words pages instead of navigating deep into the boards to find those things!

Core word pages can also be printed and laminated to make a portable, water proof and convenient solution on the road, in the pool or on a walk.  If you go to an office center like Staples or Office Max (or online at Vista Print) you can print out a core word board poster size (and have it laminated) to use around the house, outside or even hang it over the AAC users bed on the ceiling so he or she can "talk to myself".

You can try doing this sentence building activity yourself.  Try it at a staff meeting with aides and others or at home with your family.  Using pointing and gestures to provide context and see how much you can say.  This activity, sort of a sentence scramble, is a great way to train communication partners in how far you can go with just core words.  It could work in training adults or children to be good communication partners.

Core words can be limiting but its better than a world of yes/no questions and hoping someone guesses the questions to ask correctly, isn't it?
