Read a practice mark
The supplied straight scale labels 0,10,20,30,40 mL and marks 20. Read the amount and unit.
Practice straight scale: 0, 10, 20, 30, 40 mL, in equal steps. The marker is exactly at 20 mL.
Tell a helper or point; no purchased measuring container is needed.
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: The paper mark is 20 mL. Reading it is practice, not proof of actual scaled-instrument use.
No equipment purchase, water handling, trip or private household data is required. Keep this ordinary practice separate from new assessment sources.
