Try: “Make one thing that helps a reader.”
Adult teaching purpose: Complete a chosen categorical question→list/table→bounded
interpretation; optional comparative representation componentST02.
1 · Prepare and invite. Offer the ordinary blank table aid or plain paper/spoken directing.
Use a safe own fictional dataset or adult-approved willing class question. Keep actual
learner-made/directing and adult operation distinct. First held Data A/B stage may be
offered separately BEFORE its worked solution; do not show staff keys or reserve sources as
practice.
2 · Model a different small example. Model a different paper-badge display: question “star
or circle?”, replies star, circle, star, no reply. Build a list, category table star2/circle1,
separate no reply1, and a small sign “star had more of the three recorded choices; one
reply unavailable”. Say why this can help a decision without proving a whole group's
preference.

3 · Guide one attempt. Review the child's question or use ordinary MODEL3. Check
purpose/options, one record per reply, full table and scope. Ask the child to choose one
helpful feature: title, category explanation, zero row, source list, count key or no-response
note. Adult feedback asks a question first; it need not dictate a layout.
4 · Your own useful turn. Create/direct a small usable sign/table or a read-aloud
explanation. Try it on a new question yourself or invite a willing reader to use it. Keep an
actual misunderstanding or useful comment if one occurs; otherwise call the next step a
test plan. Child chooses one revision. The output may stay private and unfinished; one
meaningful decision matters more than a poster quota.
5 · Observe and record. Keep the actual choice, representation, method and meaning
before a correction. Distinguish a source fact, child decision, adult reading/scribing/handling
and mathematical hint. Observe exact data accounting and a bounded helpful statement.
Choose the specific missing component for later ordinary teaching: one variable, category
boundary, exact-once list, frequency check or inference limit. A supported revision remains
separate from first evidence. If secure, compare two representations for the same data,
then identify what neither records. Day50's later capture requires an actual teaching
interval, not just the label later.
6 · Teach next and revisit. Choose just the applicable next teaching in step5, on a different
ordinary source; then offer a new question after an actual interval. Record what happened
rather than completing all branches. Read the three participation choices
(../ROUTES.md#day-45); parent offer (../family/home-45.md) is optional. A short useful
attempt can replace a long sheet. Full source/rights and curriculum evidence stay in the
adult mapping (../curriculum/MAPPING.md) and notice (../legal/NOTICE.md).

**Try:** “Make one thing that helps a reader.”

**Adult teaching purpose:** Complete a chosen categorical question→list/table→bounded interpretation; optional comparative representation componentST02.

**1 · Prepare and invite.** Offer the ordinary blank table aid or plain paper/spoken directing. Use a safe own fictional dataset or adult-approved willing class question. Keep actual learner-made/directing and adult operation distinct. First held Data A/B stage may be offered separately BEFORE its worked solution; do not show staff keys or reserve sources as practice.
