Maths practice the whole room can see.
Quick maths review usually means one student answers while everyone else waits. In The Going Up Fix™ every team solves at the same time, and the answer is shown with their whole body.
What actually happens
The Fixes run a neon hotel tower, and each colour team rides its own glass elevator. When the brass doors open, every team gets its own button panel: two ten frames with different numbers for each team, so teams cannot copy each other. Each team has two answers beside it. The top answer means stand and the bottom answer means sit, with a picture of a standing or sitting figure beside each number. Teams agree, move together and freeze when the doors lock.
What the teacher does
Press Open the doors. When the chime sounds, the panels show the answers and the right button glows. Tap any team that got it wrong or moved after the chime, then press Send them up and watch the elevators ride.
