Try one tiny turn.

Prepare: MODEL whole 360 cm and known piece 175 cm; words/paper only.

Invitation: Keep the unknown empty until the child tries. Find the missing length and check by addition.

Adult worked model/check: 360 − 175 = 185 cm;175 + 185 = 360.

Choice and boundary: Adult reads wording if wanted without doing the computation first. No actual cord/cutting needed.

Usual communication, exact scribing, private/untimed work and stopping are welcome. Keep a model answer separate from your child's own attempt; do not correct it silently. Observe one useful reason and choose a new unrelated example if wanted.
