# X03 · Make a helper-proof frame

**Prepare/source:** Paper rectangle and broad labels top/centre/bottom; fictional two positions centre then top for one named marker. **Do:** Child chooses label words, directs a willing helper to place/read markers, revises only with actual feedback if received. **Worked reasoning:** A stable explicit reference makes the comparison reproducible as a paper task, not calibrated astronomy. **Outcome:** Usable frame instructions. **Next help:** If helper moves frame, name that action and try one wanted correction. No body contact/tactile requirement.
