A high-stakes, interactive classroom competition designed for 3rd-grade mastery.

The Unfair Game transforms standard math practice into a thrilling experience of risk, reward, and tactical decision-making. Specifically built for students to master multi-digit addition and subtraction (Standard 3.M.NBT.A.02).

🎯 The Objective

In a world where the rules are flipped, the goal is simple but counterintuitive:

Finish with the score closest to 0 to win!

🕹️ How to Play

  1. Solve to Earn: Players are presented with challenging 3rd-grade math problems. Solve them correctly to earn the right to influence the game.

  2. The Decision: If you get the answer right, you face the ultimate choice: Do you keep the hidden points for yourself, or do you "gift" them to your opponent?

  3. The Reveal: Flip a tile on the mysterious 36-card grid. Behind each card lies a hidden value ranging from +9 to -9.

  4. The Twist: Because the goal is the lowest score, a +9 is a disaster for you but a perfect "gift" for your rival. Conversely, a -9 is a golden treasure to keep for yourself!
