The Lost Son (Prodigal Son) in Luke 15:11-24 is one of the terrific presentations found in the SunScool Bible App for Kids.
It is found in the "Parables" section of the app's menu when you select either Level 1 or 2 (it isn't in 3 or 4). A slightly different retelling is found under the "Who is Jesus?" menu in the app in all levels (though its activities require the ability to read).
Update: Member Luanne Payne has created a Lost Son (Prodigal Son) Stories, Activities, and Answers Guide for the SonScool Bible App for Kids, the PDF is attached to this post and you can download it here.
The App is free, ecumenical, and can be downloaded for use on tablets, smartphones, Windows, and Mac! Get the download link and look up the story you need in our Outline of all 170+ stories in SunScool. That page also includes app helps.
