I use this with my students that have special needs. Sometimes they cannot explain to me what is going on. The visual helps them pick what they are feeling so that we can resolve the issue quickly. I do not use all the flashcards at once because that would be overwhelming. I started with 10 flashcards, until they understood the system, and then I worked my way up.
This works for a student I have that is nonverbal. He is not able to tell me when his stomach is upset or when he needs a break. He uses the visuals to pick what he wants to tell me.
I also use this with a very high functioning student that sometimes has trouble verbalizing their wants/needs. If she wants to ask for a fidget or a break she goes and grabs one of the cards.
** 30 Flashcards are included
Wants (bathroom, thirsty, hungry)
