Try: “Show one idea you can use again.”
Adult teaching purpose: Child-selected evidence and teacher next move; source-specific
components, not full Year2 judgment.
1 · Prepare and invite. Review actual ordinary work from this fortnight or offer a new
ordinary task if nothing was retained. Keep the selected held stage/source/own responses
separate from worked examples and staff keys. Check actual source familiarity, wanted
access, interval and teaching. A later stage is later only after a real first capture and
intervening teaching. No required score or public comparison.
2 · Model a different small example. Model reflecting on unrelated addition14+9: “I split9
as6 and3 to reach20, then23; my check used14+9=23. Next I want to choose a useful
missing-part problem.” This names a mathematical action and next question, not “I am a
visual learner” or a level label. Let a child reject a reflection stem and communicate in their
usual way.

3 · Guide one attempt. Child selects one table/count interpretation or one number
representation/problem. Ask “Which part helped? What is still tricky?” Keep their actual
wording. Teacher compares the actual response against only its component criteria and
support. A plan or adult demonstration cannot substitute for the child's own observed
mathematical choice.
4 · Your own useful turn. Offer a suitable unseen later/core/reserve Data or Number source,
individually complete, only where appropriate. Capture the four own responses before
feedback. Otherwise choose a new ordinary source and label it practice/first encounter.
Child can pause, direct/scribe privately or stop. Record first response separately from a
supported correction; an unanswered question is not assumed incorrect reasoning.
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. Use the exact missing component to choose unrelated next
teaching: category boundary/exact-once list/unknown claim; hundreds comparison/zero
place/value exchange; part-whole operation/bridge partition/contextual check. Set a
concrete new example and check question, and agree a later opportunity when possible.
Retain exposure/help/interval records. Do not add unlike first/later task totals into a growth
or annual attainment claim.
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-50); parent offer (../family/home-50.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:** “Show one idea you can use again.”

**Adult teaching purpose:** Child-selected evidence and teacher next move; source-specific components, not full Year2 judgment.

**1 · Prepare and invite.** Review actual ordinary work from this fortnight or offer a new ordinary task if nothing was retained. Keep the selected held stage/source/own responses separate from worked examples and staff keys. Check actual source familiarity, wanted access, interval and teaching. A later stage is later only after a real first capture and intervening teaching. No required score or public comparison.

Let a child reject a reflection stem and communicate in their usual way.
