• Keep the two adult-only cards off the learner screen. Have a pencil and scrap paper if useful; oral pointing/typing/AAC can replace handwriting unless spelling or composition is the target. No printing, cutting, account or purchase is required.

• Open Show first, read the explanation together, and pause to check the central idea. Then do Guided Try together.

• For Try, close earlier models and the adult keys unless the task explicitly supplies a reference. Record any hints, read-aloud help or model reopening; do not call supported work independent.

• Use only the active learner card. Keep the private key closed until an attempt is recorded. Stop or take a break on request; practical claims stay not observed unless actually done.

Use on screen; read aloud or recreate a tactile model only with declared support. No printer or purchased kit.

Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.
