Core Skills
Math Forge
Combine the four numbers with + − × ÷ and brackets to hit the target — and forge a robot part by part as you solve. 8 tiers from grades 1 to 12. Play free solo, or run a live class where students race the same puzzle on their own devices.
For Educators
Built for the classroom
Mental math, order of operations (BEDMAS), and number sense — students hunt for an expression that equals the target, building fluency and flexible thinking rather than rote recall.
Grades 1–12 · 8 difficulty tiers. The host picks the tier; start a new match to change it for a mixed-ability room.
Three ways to play
-
Play free (solo)
No login. Great at home or as a warm-up — build robots at your own pace and collect them in the Garage.
-
Host a live class
Open a room on the projector; a 4-letter code + QR appear. No 1:1 devices? Run it teacher-led on the one screen.
-
Join on a device
Students enter the code (or scan the QR) and race the same puzzle each round on a phone or laptop.
Run a live class in 5 steps
- Open the Forge Floor — pick solo or teams, and a difficulty tier.
- Share the 4-letter code / QR on your screen; students join on their devices.
- Start the round: everyone gets the same target. Fastest correct answer scores most (solving always scores — never negative).
- Watch the live leaderboard; hit “Call Time” when you’re ready for the next robot part.
- After the last part, the winning robot wakes up on the podium. No accounts — scores live only while the room is open.
Tip: host on a laptop or projector (the big screen shows the code, QR and leaderboard); students join on their phones or laptops.
