I wrote this readers theater script called:
Working Together: The Fact Family Triangle
You can download a copy of the script by Clicking HERE.
I think it would be fun for a 3rd or 4th Grade Class to present to a First or Second Grade Class as a play. The costumes are minimal and the message is important. No need to memorize the script as I would just present it in Reader's theater format.
Let me know if you plan to try it in your class as this is my first attempt at writing a play about a math concept.
