What happens when thousands of students unite to solve math puzzles on the same day?Momentum. Magic. JiJi Day.
Friday, April 25, 2025 is JiJi Day, and this year, we’re going big. We’re calling on every ST Math classroom to join the first-ever National JiJi Day Puzzle Challenge—a collective, coast-to-coast celebration of learning, problem solving, and perseverance.
Whether your students are just beginning their ST Math journey or racing toward year-end goals, every puzzle solved on JiJi Day moves us forward—together.
It's not a competition—it's a nationwide movement.
We’re inviting classrooms across the country to help us reach a shared goal: Solve as many ST Math puzzles as possible in a single day.
You’ll be able to:
JiJi Day is more than just a party. It’s a powerful reminder that math is for everyone—and that perseverance, curiosity, and a little bit of fun can turn struggle into success.
Every puzzle holds potential. Every student brings something unique to the table.
When we come together to learn, to try, to think, and to celebrate—we show what’s possible when students lead their own math journeys.
Whether you're hosting a JiJi-themed dress-up day, tracking your classroom’s puzzle total, or designing your own puzzles for a chance to be featured, there are countless ways to join the fun.
