Before the session
- Choose one observable skill—measure, mark, hold, smooth, dry-fit, or inspect—instead of trying to cover an entire project.
- Prepare a safe sample and a completed reference so the learner can compare before and after.
- Use plain language first, then introduce the technical word next to the real part or action.
During the session
- Ask what changed, what stayed aligned, and what the learner would check next.
- Give a correction to the work or setup, never a vague judgment about the learner.
- Let the adult handle tool setup, speed, structural correction, and any step the plan marks adult-controlled.
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.
