Written by educational RPG designer Michael Low, ArithMagine is a role-playing game for all ages to play, learn, and create together while building numeracy. 

Using simple math mechanics and a deck of cards, ArithMagine is easy to learn, but leads to edge-of-your-seat moments of drama, incentivizing collaboration and positive play in order to succeed!  

Though ArithMagine can be played on its own, it's designed to work with any tabletop RPG, and specifically in concert with StoriesRPG.  Here's a quick link library for all the StoriesRPG resources to help build a better learning story-game experience:


  • Core RulesA one page RPG focused on helping players tell stories of drama, excitement, and adventure together.  All you need is four 6-sided dice, paper, stuff to write with, and at least two people!
  • Scenes: A tool for outlining scenes for stories or games that's easy, collaborative, and intuitive.
  • Drama Clocks: Epic, spine-tingling, edge-of-your seat scenes where every Move counts - but without the violence!
  • Power UpsAn approach to "powering up" where writing becomes joyous - a source of character growth and peer support!
  • Teller Moves: A set of 16 quick-reference cards with strategies to help you run an engaging, collaborative, compelling, educational game for anyone!


  • Starsworn: A monthly set of print and play, play to learn adventures with read-aloud passages, coloring book illustrations, maps, and even a set of podcast stories from StoriesPodcast that follow a group of heroes on a parallel quest!  At 40 pages each, these play-at-home books are a steal!
  • Chapter 1Legends say magic came when the stars fell.  At this year's Starfall fair, a group of everyday people will rise to become heroes when they fall again - and be swept up in grand and heroic events!  Best of all?  Chapter 1 is pay what you want - go grab a copy now!
  • Chapter 2The heroes must journey to the Far Swamp to seek the Frog Witch, the only sage wise enough to help them unlock their powers. But strange forces are at work, and the stars have caused great chaos across the land ...
  • Chapter 3The heroes are summoned on a great quest ... to go to school! The Celestial Conservatory promises to train them in the use of their Starsworn powers - but what secrets does it hide?


  • World Building: How to help kids build their own worlds, with their own lore and internal logic.
  • Educator's Guide: This will be a longer work, and explain, step-by-step, strategies for using StoriesRPG to teach academic content in classrooms, including Common Core Standards, assessments, pacing guides, grouping strategies, and more!

Feel free to reach out with any questions, and hope this supplement boosts your stories to the next level!
