One small rule can change the whole game.
Game Reasoning is a classroom-ready systems reasoning resource that helps students notice how rules, roles, boundaries, goals, scores, time limits, equipment, and communication shape what a system can do.
Students begin with a familiar game, identify its parts and relationships, then change one rule or feature and track what changes first, who or what is affected, what stays the same, and what evidence supports their explanation.
This is not a PE skills lesson or a lesson about winning. The game is the visible system. The learning is in noticing what affects what.
