The Parable of the Rich Farmer, Rich Fool in Luke 12:13-21 is one of the terrific presentations found in the SunScool Bible App for Kids.
It is found in two places in the app in slightly different versions: (1) Under the Parables menu only when you select "Level 3" (grades 2-5), and (2) Under the Who is Jesus menu for all ages (but will require some reading help to complete the activities).
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.
