One exact instruction

Ask, “What should happen first with your ready sheet?” Keep the child's own instruction before an adult example. With locally suitable paper, the child may place/mark one part or direct a willing adult exactly. Name the actual actor. Ask a next-use or return step, retaining it as proposed unless done. Finished work can be kept intact. No cutting, tidy-up quota or reward for touching is required.

Grown-up help

Next help: replace a vague “do it” invitation with a neutral question about which part and place; do not complete the design.
