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 larger optional project, 20–40 minutes or several sittings unpiloted; not proof practical making, independence or whole code attainment.

Numbered moves

  1. Read the complete fictional source; name wanted quantity and units. Select a representation after checking the day entry.

  2. Make a source/problem/strategy note. Work the stated problem on own paper or usual communication.

  3. Compare with a separate adult possibility only after available own work: 216 difference.

  4. Build the intended tangible note/puzzle/gallery or exact description. Create a comparison card for a maker: retained both whole counts, gap label, no preference from size alone.

  5. Try a different stated condition if wanted. Label the first and changed version separately; keep/check/change/pause/finish are choices.

Purpose

Create a comparison card for a maker: retained both whole counts, gap label, no preference from size alone.

Routes

  1. Instruction

    State quantities and try one operation with smaller whole counts. Keep actual mathematical help visible.

    Name

    One useful component

  2. Instruction

    Create a comparison card for a maker: retained both whole counts, gap label, no preference from size alone.

    Name

    A note another maker can read

  3. Instruction

    Select one count to change by 10–50 while keeping nonnegative values. State all new conditions, compute and check; an uncomputed change is a plan.

    Name

    A second version
