The theme for 2024: Playing with Math
Every year we announce a theme to flavor the celebration, spark creativity and bring light to connections between mathematics and all sorts of fields, concepts and ideas.
In 2024 we want to celebrate mathematical games, puzzles and other entertaining activities, but also "playing" with mathematics itself, exploring, experimenting, and discovering.
Play with the theme!
In some languages the verb play means other things, like "performing" and instrument, or "acting" in a theater.
