Small games that teach one idea each.
Free, no login, runs on a Chromebook or a phone. Each game takes 10 to 20 minutes and ends with the student having figured something out, not having been told it. Teacher guides included.
Draw the Lines
Draw voting districts for a tiny state. Then get hired by the losing party and make them win anyway. Packing, cracking, compactness rules and the efficiency gap, learned by doing them.
Rigged or Random?
Fake a coin and get caught by a detector. Spot the fake. Pick the best shooter on a team where everyone is equal. Find the jelly bean that "causes" acne. Streaks, luck and false positives in 15 minutes.
Discovery, not delivery
The student does the gerrymandering. The student gets fooled by the leaderboard. The idea lands because they produced it.
Immediate feedback
Every click updates a scorecard. Students form a guess, test it, and adjust in seconds, dozens of times per lesson.
Zero setup
A link. No accounts, no installs, no data collected. Progress is saved on the device. Works on Chromebooks, tablets and phones.
Built for the debrief
Each game ends in a discussion. Teacher guides give the questions, the misconceptions to listen for, and a 45-minute plan.
