Things a commerce class argues about.

Four ways to run one.

A library that only works when the wifi does is a library that goes unused. Most activities here run more than one way, and the pack decides which.

On thirty phones

A six digit code and a QR on the screen. Nobody installs anything and nobody makes an account. Scored live, and the standings go up where the room can see them.

On the board alone

No devices in the room at all. The options stay on screen and the room answers out loud. This is the version that still works the week phones are in a box at the door.

Printed and cut up

Card sorts and worksheets with a facilitation script and an answer key, each section on its own sheet so the key never shares a page with the handout.

In a computer lab

A spreadsheet task and the same file with every figure in it. The answers are computed by a calculator rather than typed, because a room checks those in real time.
