Groups of three fold real paper cups and test them with water. A trainer teaches a new worker three ways: telling for 30 seconds, teaching from a job breakdown sheet, then using the four-step card. The kit has a 7-page facilitator guide, the fold drawings, the four-step card, the job breakdown sheet, an observer tally and a results board, with filled-in examples.

Watch how to run it (about 5 minutes)

Letter-size. Each group also needs scissors, a pen, a tray and a jug of water.
