Kindergarten.com is offering all of their ABA apps free for the month of April in honor of Autism Awareness Month. I was actually going to purchase some this week after hearing about them over at Unringing the Bell. Really, I bought an iTunes card at the grocery store this weekend so I could get my fuel discount. Glad I didn't have time to use it!
FYI: The ones listed under the heading Flashcards were always free and the rest of them were 99 cents.
I would recommend the receptive language ones and I downloaded the Action Flashcards for Goldie because verbs are something she has been working on in speech.
