These pictures are also useful to adapt academic activities in the classroom for nonverbal students. The main problem I have found with this program is that I end up with SO MANY pictures and nowhere to store them!
I have tried several ways of storing them, until I found the one that worked best for me. I bought clear plastic baseball card holders at target and put them in a binder. Then I organized pictures according to categories. A section of pictures in alphabetical order, a section of schedule pictures, etc. This takes up little space and allows easy access to your pictures whenever you need them!
