Natural Math’s first-party toolkit says Math Storytelling Day is celebrated on September 25 and explains how Maria Droujkova and Sue VanHattum developed the observance.
About Math Storytelling Day
Math Storytelling Day is celebrated on September 25 as a participatory day for telling, making and sharing stories in which mathematics matters.
Natural Math’s first-party history traces the idea to Maria Droujkova, Sue “Math Mama” VanHattum and their math community, who combined a shared birthday with their interests in mathematics and stories.
Why Math Storytelling Day matters
The day treats mathematics not only as calculation but as something that can appear in narratives, jokes, comics, cultural traditions, theatre, puzzles and imaginative worlds.
Its educational value is in helping learners connect mathematical ideas with language, creativity and social participation.
History of Math Storytelling Day
Natural Math says Sue and Maria both loved mathematics and stories and shared a birthday.
The history says Maria researched holidays, looked for patterns and brainstormed with Sue and other math friends; that process produced Math Storytelling Day.
The creator-community toolkit invites everyone to participate on September 25 and describes celebrations in families, schools, libraries, math-education organizations and math circles.
The reviewed first-party material documents the tradition by 2015 but does not establish the exact first annual observance year, so the guide leaves that field unresolved.
How the observance developed
This timeline uses documented milestones from reviewed sources. Missing stages are left out rather than guessed.

Math Storytelling Day Facts
Math Storytelling Day is observed on September 25.
Natural Math’s origin story centers Maria Droujkova and Sue VanHattum, with other math friends involved in brainstorming.
September 25 is tied to the shared birthday of Sue and Maria.
