# Three different records Match “0 mL”, “not recorded” and “spill” to value, missing and invalid. Three supplied labels: 0 mL; not recorded; spill. The first is a value; the second is missing; the spill makes this comparison invalid. Use three spoken choices or ordinary drawn cards; no calculation worksheet is required. Try one small explanation, then stop or return later. Tell or show it in your usual way: words, drawing, pointing, signing, typing, dictation or your communication device. Work quietly or privately, pause, ask for a helper, or return later. Sharing and recording are optional.
Grown-up help **Useful response:** Zero is a supplied recorded value; not recorded is missing; spill is invalid for this comparison. No equipment purchase, water handling, trip or private household data is required. Keep this ordinary practice separate from new assessment sources.
