Before the session
- Prepare labeled kits and set an adult-only station for any cutting, drilling, fastening, glue, or finish work.
- Give each station one job—sort, measure, sand, dry-fit, observe, record, or cleanup—and one completion check.
- Plan the stop signal, movement path, material return point, and a quiet alternative for a learner who is waiting.
During the session
- Keep groups small enough that each learner has a real role, not only a turn watching.
- Use a completed sample to make part orientation and inspection criteria easy to see.
- Record the group result and any incomplete adult-controlled work so it does not become an untracked next-session hazard.
Finish well
Leave the space safer and easier to restart: return materials, label any unfinished work, note the learner's actual role, and decide the next adult-controlled check before the session ends.
