Exact complete national selection
NATIONAL.json retains every138 canonical selected record, full HTML attributes/plain meaning, canonical pin and inherited acquisition metadata unchanged. NATIONAL-MEANINGS.md is a full reader, not a code-only list. RAW.json keeps every actual1650 cell slot with absent/present-empty/present-value distinctions, native cell attributes/styles/types/shared-string indices and full decoded values. NATIVE-XML.json keeps all138 complete native row-XML byte substrings with hashes and complete worksheet/shared-string identities. The current official workbook was actually acquired20013October2026, same exact inherited bytes/SHA db446882d2c00cf7c085a03e250e2442fda6c44011fc114680c46c1dc7a822c3 . Attribute-level equality verifies the selected records. Selection is not a full workbook curriculum-meaning review.

Full year achievement-standard boundary
By the end of Year 4, students use their understanding of place value to represent tenths and hundredths in decimal form and to multiply natural numbers by multiples of 10. They use mathematical modelling to solve financial and other practical problems , formulating the problem using number sentences, solving the problem choosing efficient strategies and interpreting the results in terms of the situation. Students use their proficiency with addition and multiplication facts to add and subtract, multiply and divide numbers efficiently. They choose rounding and estimation strategies to determine whether results of calculations are reasonable. Students use the properties of odd and even numbers. They recognise equivalent fractions and make connections between fraction and decimal notations. Students count and represent fractions on a number line. They find unknown values in numerical equations involving addition and subtraction. Students follow and create algorithms that generate sets of numbers and identify emerging patterns. They use scaled instruments and appropriate units to measure length, mass, capacity and temperature. Students measure and approximate perimeters and areas. They convert between units of time when solving problems involving duration. Students compare angles relative to a right angle using angle names. They represent and approximate shapes and objects in the environment. Students create and interpret grid references. They identify line and rotational symmetry in plane shapes and create symmetrical patterns. Students create many-to-one data displays, assess the suitability of displays for representing data and discuss the shape of distributions and variation in data. They use surveys and digital tools to generate categorical or discrete numerical data in statistical investigations and communicate their findings in context. Students order events or the outcomes of chance experiments in terms of likelihood and identify whether events are independent or dependent. They conduct repeated chance experiments and describe the variation in results.
The block offers actual future evidence only for the taught additive strategy/modelling, estimate and unknown-equation relationships. It does not complete the Year4 achievement standard. Fraction/decimal/place-multiplication/parity/algorithm opportunities earlier in the fixed tree remain partial. Measurement, space, statistics, chance and the other retained descriptions require their own instruction and actual evidence.
Queensland · using the guidance fairly
The April2025 official11-page standards-elaborations PDF was read as complete operative parsed text; all871 numbered lines are saved with actual web provenance. The two403DOCX responses remain unsuccessful acquisitions. No matrix-diagram inspection is inferred. The two-page March2023 alignment and three-page October2023 techniques/conditions were read in full operative parsed form; direct download403 is kept distinct from web success.
The standards elaborations support teacher on-balance judgement about qualities in a folio across the year/band, using opportunities actually taught and observed. Achievement-standard expectations relate to the C standard. Understanding, fluency, reasoning and problem-solving interact; correct calculator/Bench output, copied wording or an adult representation does not supply an unobserved learner proficiency. The32 original criteria are formative task-specific statements, not official calibrated A–E bands, grade conversions or causal progress measures.
Simple familiar tasks have few obvious elements and identifiable procedures with no needed interpretation/analysis. Complex familiar work has several elements and some interpretation/analysis within identifiable procedures or prior related experience. Complex unfamiliar work has unclear procedures and limited prior related experience, needing interpretation, clarification and analysis. Number size or route letter alone does not assign a complexity/band: actual prior experience, scaffolding, steps, representations and cross-strand links matter. Do not make route A/B/C permanent learner categories.
Schools choose range/balance and appropriate local contexts. The guidance lists project modes as written/spoken-signed/practical/multimodal and supervised modes as written/spoken-signed/practical. Teacher observation can contribute documented evidence against relevant achievement aspects. These everyday proposals are not official supervised assessments by default. Its suggested project up-to200 words/one-minute spoken-signed and supervised up-to40 minutes+5perusal/planning/instruction/up-to200total/50per short item are suggestions, not daily quotas or requirements to fill all boxes. Tasks may be staged and exact instructions read; longer responses do not necessarily offer better evidence. Practical work needs schools' current safety arrangements. Here paper descriptions, usual communication and agreed helper direction are fully available; no purchase, actual stock handling, recording or public display is required.
A real Australian fact with an original small application
The RBA's current education page gives Australian banknote denominations $5,$10,$20,$50,$100. Source: Reserve Bank of Australia2026, https://www.rba.gov.au/education/topics/banknotes/ , direct200 and narrow sentence verified13October2026. Optional ordinary application: use original plain number cards labelled20,50,10 dollars. The invented total is80dollars; to reach a hypothetical100-dollar target would need20more. Child can choose just one sum/check, use a card-count analogue or skip money. No actual banknote possession, design copying, current price, transaction, cash-handling skill or personal finance is claimed. Staff model20+50+10=80; inverse100−80=20. RBA images/designs are excluded; use plain original text/shapes only.
Local information that a teacher can review
- Choose a narrow nonpersonal quantity from an actual current official publisher, or count an authorised shared fictional/ordinary collection.
- Save the publisher/place/URL, date checked, complete quantity/unit and any uncertainty. If a source is undated or inaccessible, keep it held.
- Check rights/permission before copying; a link or plain original paraphrase can suffice. Avoid pupil identities/location histories, FirstNations translations or cultural knowledge without authority.
- Distinguish the real stated fact from original invented numbers and the child's actual observation. Verify arithmetic and compare a second primary source when conflict matters.
- Restate the complete new situation and answer conditions. Test the prompt/criterion/art together; changes are not silently equivalent-difficulty forms. Record what remains unverified. This is a paper/edit workflow, not a live-data service. Council403/undated brochure are not current availability evidence.
