This story is called: "What are Talkers for? A Story about Different Voices"
I made it to address the jealousy and fighting I saw in classrooms when one child gets an iPad to use as a communication device, but the other kids don't have one. Although with a little alteration, you could make the story to explain to a child who uses a talker the reason that it doesn't have games. Just print, cut the pages in half, bind, and you've got yourself a little four page book with lots of pictures.
