A tray after use
Full educator lesson · Pupil invitation · Empty work mat · Optional home activity · Larger project · Written read-together script · Additive Work Bench
Access
Show, draw, type, sign, use your usual communication or direct an agreeing helper. Choose quiet/private work, switch a route, pause, pass or finish. One useful part is enough. A helper can read the exact words or scribe your choices; supplying an operation, count, regrouping or reason is mathematical help and is named. No speed, neatness, speech, handling or device requirement.

Notice
Ordinary optional home practice, not unseen assessment or proof a child actually handled stock. Suggested 5–12 minutes, unpiloted; stop after a useful part.
Numbered moves
Read the stated source and choose paper, description or usual communication. Use 30−8 first if regrouping needs teaching.
Try one own way before the grown-up model. Keep your values and unit labels.
Grown-up separate practice possibility: Rename 102 as 9 tens 12 ones; subtract 3 tens 8 ones=64; check 64+38=102.
Receive one available explanation or check. Ask whether to keep, change, pause or finish; another example is optional.
