Math Challenge is OPEN for the 2026/2027 school year! 

 

 

 

🐻 Welcome, Grizzly Math Detectives!

Every two weeks, a brand-new set of puzzles drops, and your mission is to crack them. Some will make you think hard.  and every one of them will make your brain stronger!

You don't have to be a "math person" to join. Every great problem solver started exactly where you are: curious, and brave enough to try.

  • Everyone's invited. Every grade, every Grizzly!
  • It's totally free, thanks to our amazing Grand Ridge PTSA.
  • 15 challenges, all year long. Check the Schedule Calendar below to see when each challenge (and its solutions) will be released.

👨‍👩‍👧 Grown-ups, join the fun!
Some of the best math happens around the kitchen table. Solve together, ask "How did you figure that out?", and cheer for the thinking, not just the answers. Talking through ideas together is one of the best ways to grow a strong problem solver.

 

🧠 How to Play

  • Grab the challenge. Click CURRENT MATH CHALLENGE to see the newest puzzles. A fresh set drops every two weeks (see the schedule below).
  • Dig in! Work on your own or team up with family. Draw pictures, make lists, try a wild idea. Show your thinking; that's where the magic happens!
  • Send your answers. Submit them online using this form by the due date.
    Answers must be submitted online. You'll usually have about two weeks from when a challenge comes out to when it's due.
  • See how others cracked it. Solutions are released with the next challenge. Check your work, discover new strategies, and think about how you solved it. There's often more than one path to the answer, and finding a new one is a win too!

📬 Never miss a challenge!
Join the Grand Ridge Math in Action mailing list.
We'll send you a reminder when each new challenge drops, when it's due, and any fun news along the way.

🏆 Prizes, Glory… and a Party!

  • Complete at least 10 challenge sets this school year and you'll be celebrated at the end of the year with a certificate and a prize!
  • Complete ALL 15 challenge sets and you're invited to our end-of-year Math Party to celebrate your amazing effort!

You don't need every answer right to earn these. What counts is showing up, giving it your best, and sending in your thinking. Mistakes are just clues on the way to the answer!
